Detailed Description Transfer port systems can be designed with interlock systems to enhance their robustness and safety. Interlock assemblies can be configured to prevent the port door from opening when a mounting assembly is not docked to the port frame flange. Interlock assemblies can also be configured to prevent the mounting assembly from being removed from the port frame when the port door is in its open position. Ensuring that the port door can only be opened when a mounting assembly is docked PDSD No.162.0046WOU1 to the port frame flange prevents the exposure and contamination of the contents of the mounting assembly and the ambient and isolated environments on opposing sides of the barrier wall. The present disclosure is directed towards a toggle interlock system for a rapid transfer port system. In various embodiments, the rapid transfer port system can have a rapid transfer assembly including a port frame configured for placement in a barrier wall and defining a port opening extending from a first side to a second side of the barrier wall. The port frame can further include a port frame flange at the first side of the port frame and define a first set of mating features. The transfer port assembly can include a port door coupled to the second side of the port frame and configured to selectively obstruct the port opening. The transfer port assembly can include a toggle movably mounted to the port frame flange and a locking lever assembly mounted to the port frame. The locking lever assembly can include an interlock plate, the interlock plate defining an interlock slot, wherein the toggle is configured to selectively engage with the interlock slot. In various embodiments, the locking lever assembly is configured to move between a locked position wherein the port door is fixed in a closed position and an unlocked position wherein the port door is configured to move from the closed position to an open position. The transfer port system can further include a mounting assembly having a mounting assembly flange defining a second set of mating features configured to engage with the first set of mating features. In various embodiments, the locking lever assembly is fixed in the locked position when the toggle is engaged with the interlock slot. In various embodiments, the locking lever assembly is configured to move between the locked position and the unlocked position when the toggle is disengaged from the interlock slot. In various embodiments, engaging the first set of mating features with the second set of mating features disengages the toggle from the interlock slot. In various embodiments, the interlock assembly of the transfer port system accomplishes the function of a mounting assembly interlock, which can also be referred to as a cannister interlock, beta interlock or container interlock. A mounting assembly interlock keeps the mounting assembly from being removed unless the port door is closed. In other words, the mounting assembly can only be removed if the port door is closed. PDSD No.162.0046WOU1 In addition, or alternatively, in various embodiments, the interlock assembly of the transfer port system may accomplish the function of a port door interlock, because it prevents the port door from opening if the mounting assembly is not in place. In other words, the port door can only be opened if the mounting assembly is locked in place. In some embodiments the interlock assembly of the transfer port system can reduce the overall footprint of the transfer port system. For instance, the interlock assembly can be configured to allow for certain components of the transfer port assembly (e.g., actuation lever(s), gear boxes(s), or the like) to be mounted directly to the port frame. Such a configuration can eliminate the need for a mounting plate and simplify the installation of the transfer port system. Transfer Port System Overview (FIGS.1-5) Referring now to FIG.1, a cross-sectional side view of a transfer port system is shown in accordance with various embodiments herein. Transfer port systems are sometimes referred to as rapid transfer ports or RTPs. In various embodiments, the transfer port system 100 can include a transfer port assembly 101 having a port frame 102 extending from a first side 104 of a mounting plate 103 to a second side 106 of the mounting plate 103 and a mounting assembly 110. In various embodiments, the mounting plate 103 can be installed into a barrier wall. In various embodiments, the first side 104 of the transfer port system 100 can be consistent with ambient conditions in at least one implementation of the technology described herein. In various embodiments, the second side 106 of the transfer port system 100 can be consistent with conditions that are relatively cleaner or dirtier than the ambient conditions in at least one implementation of the technology described herein. The mounting plate 103 and the port frame 102 generally prevent contamination between the first side 104 and second side 106. The words ambient and isolated will be used herein to refer to the two different sides 104, 106 of the transfer port system respectively, where the isolated side 106 is the isolated side of the system that can be a relatively “clean” or “dirty” side, and the ambient side is the opposite side of the system. The isolated side 106 of the system can generally be contained on all sides by one or more barrier walls. It will be recognized by those of skill in the art that adjectives such as “dirty” or “clean” are non-limiting to the technology described herein. Indeed, the isolated environment, in a PDSD No.162.0046WOU1 variety of instances, can be a contaminated or dirty environment and the non-isolated environment can be the relatively clean environment. In various embodiments, the transfer port system 100 can include a port frame 102 that is configured to extend through a port opening 108 defined in the mounting plate 103 in fixed, leak-proof, sealed engagement with the periphery of the port opening 108. As such, the port frame 102 mutually defines the port opening 108 which extends through the mounting plate 103. A port door 112 is pivotably coupled to the second side 106 of the port frame 102 with a port door hinge (not shown in this view). The port door 112 is generally configured to selectively and sealably obstruct the port opening 108. In the example of FIG.1, the port door 112 is shown in a closed position in leak-proof sealed engagement with the inside perimeter of the port frame 102. However, in various embodiments, the port door 112 is moveable to an open position. As a broad overview, to transfer items in and out of the isolated side 106 of the transfer port system 100 from the ambient side 104 of the transfer port system 100 without exposing the transfer items to the ambient conditions on the ambient side 104 of the transfer port system 100 requires that a container or other type of mounting assembly 110 containing the transfer items be sealably mounted to the port frame 102 such that when the container is opened, the contents are only exposed to the isolated side 106 of the transfer port system 100 through the port frame 102. This can be accomplished by sealably mounting the container around the transfer port system 100 (such as to the port frame 102). When the port door 112 is then opened, the inside of the mounting assembly 110 communicates with the port opening 108 such that the contents of the mounting assembly 110 can be moved into the isolated environment 106. The mounting assembly 110 is shown alone in FIG.5, separated from a transfer port system 100, while FIG. shows a mounting assembly 110 attached to a transfer port system 100. In various embodiments, the mounting assembly 110 may include a mounting assembly flange 118 configured to mount to the port frame 102. The mounting assembly flange 118 is mountable to the port frame 102 by virtue of the mounting assembly mating features that are configured to mate with port frame mating features partially defined along a port frame flange 120 of the port frame 102 (best seen in FIG.2). The port frame flange 120 is generally the surface that the mounting assembly flange 118 is rotated against when mounting the mounting assembly 110, PDSD No.162.0046WOU1 and the port frame mating features are generally the locations along the port frame flange 120 that receives corresponding bayonets when the mounting assembly 110 is in a mounted position. The mounting assembly flange 118 is generally configured to form a leak-proof seal when mounted to the port frame 102. After mounting the mounting assembly flange 118 to the port frame 102, the port door 112 can be opened and moved out of the way of the port opening 108. One option for movement of the port door 112 is swinging about port door hinge between a closed position and an open position. In addition, or alternatively, the port door 112 can slide or move in other ways between a closed and open position. The port opening 108 defined by the port frame 102 and the mounting assembly flange 118 is open such that the environment within the mounting assembly 110 is accessible and exposed to the environment on the isolated side 106 of the transfer port system 100. The mounting assembly 110 can then be emptied or loaded. Further successive transfers may be made simply by docking a succession of mountable assemblies containing material to be transferred until the operation being performed within the isolated environment 106 is completed. Although the system is described with reference to the transfer of material into an isolated environment, the same series of steps is carried out in transferring materials from within the isolated environment to the ambient environment. The transfer port assembly 101 is generally configured to engage the mounting assembly 110, such as a container, when the port door is open, and can disengage from the mounting assembly when the port door is closed. In at least one embodiment the transfer port assembly 101 prevents translation of the mounting assembly 110 when the port door 112 is open and can permit translation of the mounting assembly when the port door is closed (and in some cases locked). Such a configuration prevents the mounting assembly 110 from being removed when the port door is open, thereby exposing the inside of the container and the isolated environment, prior to closing the port door 112. Referring now to FIG.2-3, views of a first side of the transfer system are shown in accordance with various embodiments herein. FIG.2 shows a perspective view of the first side of the transfer port system of FIG.1 with the mounting assembly removed and door closed in accordance with various embodiments herein. FIG.3 shows a perspective view of the first side of the transfer port system of FIG. 1 with PDSD No.162.0046WOU1 the mounting assembly removed and door open in accordance with various embodiments herein. In various embodiments, the rapid transfer port system 100 can include a port frame 102 having a port frame flange 120. The port frame flange 120 can define one or more port frame mating features 226 that are configured to receive corresponding mating features of a mounting assembly 110. In the example of FIGS.2-3, the port frame flange 120 includes three bayonet receptacles configured to mate with three bayonet connectors of the mounting assembly 110. Alternatively, the port frame flange 120 may include greater than or less than three bayonet receptacles in any suitable configuration. The port frame flange 120 may include any other suitable type of mating feature(s) in addition to or alternative to the bayonet receptacles. In various embodiments, transfer port system 100 can include a locking lever assembly 220. The locking lever assembly 220 can be mounted to the port frame 102 and is configured to move between a locked position (as depicted by FIG.2) wherein the port door 112 is fixed in a closed position and an unlocked position (as depicted by FIG.3) wherein the port door 112 is configured to move from the closed position to an open position. In various embodiments, the locking lever assembly 220 can further include a locking lever handle 221 and a locking lever shaft 223 extending through at least a portion of the port frame 102. In various embodiments, the locking lever handle 221 is movably mounted to the port frame 102 by the locking lever shaft 223. An interlock cover portion 232 forms a part of the port frame 102 and is located over and covers a portion of the interlock assembly. The locking lever shaft 223 protrudes from the interlock cover portion 232. In the example of FIGS.2-3, the locking lever assembly 220 is actuated between the locked position and the unlocked position by rotating the locking lever handle 221 about the locking lever shaft 223 by a set degree of rotation. In some embodiments, the degree of rotation can be greater than or equal to 15°, 25°, 35°, or 45°. In some embodiments, the degree of rotation can be less than or equal to 180°, 135°, 90°, or 45°. In some embodiments, the degree of rotation can fall within a range of 15° to 180°, or 25° to 135°, or 35° to 90°, or can be about 45°. In alternative embodiments, the locking lever assembly 220 can be actuated from the closed position to the open position by any combination of suitable movements such as pushing, pulling, sliding, or the like. PDSD No.162.0046WOU1 In the example of FIGS.2-3, the locking lever handle 221 is mounted to the first side 104 of the transfer port system 100. This gives the rapid transfer port system 100 an externally operated configuration. In the context of rapid transfer port systems, being externally- operated means that an operator can lock or unlock the port door 112 from the first (ambient side) 104 of the transfer port system 100 without requiring access to the second (isolated side) 106 of the transfer port system 100. Such a configuration can be advantageous due to decreased contamination risk and increased ease of operation. In alternate configurations, the locking lever handle 221 may also be mounted to the second side 106 of the transfer port system 100. In such configurations, an operator can access the second (isolated) side 106 of the transfer port system 100 to lock or unlock the port door 112, such as by using a glove port or automated actuator. In various embodiments, the transfer port system 100 can include a port door 112 configured to sealably obstruct the port opening 108 against the port frame 102. In various embodiments, transfer port system 100 can include a port door actuation lever 222, wherein actuating the port door actuation lever 222 from a first position (as depicted by FIG.2) to a second position (as depicted by FIG.3) causes the port door 112 to move from the closed position (where the port opening 108 is obstructed) to the open position (where the port opening 108 is not obstructed) about the port door hinge. In the example of FIG.2, the port door actuation lever 222 is mounted to the mounting plate 103. In various embodiments, actuating the port door actuation lever 222 from the second position to the first position causes the port door 112 to move from the open position to the closed position. In the example of FIGS.2-3, the port door actuation lever 222 is actuated from the closed position to the open position (or vis versa) by rotating the port door actuation lever 222 by a set degree of rotation. In some embodiments, the degree of rotation can be greater than or equal to 90°, 120°, 150°, or 180°. In some embodiments, the degree of rotation can be less than or equal to 270°, 240°, 210°, or 180°. In some embodiments, the degree of rotation can fall within a range of 90° to 270°, or 120° to 240°, or 150° to 210°, or can be about 180°. In alternative embodiments, the door actuation lever 222 can be actuated from the closed position to the open position by any combination of suitable movements such as pushing, pulling, sliding, or the like. PDSD No.162.0046WOU1 In the example of FIGS.2-3, the port door actuation lever 222 is mounted to the first side 104 of the mounting plate 103. This gives the rapid transfer port system 100 an externally operated configuration. In the context of rapid transfer port systems, being externally operated means that an operator can open and close the port door 112 from the first (ambient side) 104 of the mounting plate 103 without requiring access to the second (isolated side) 106 of the mounting plate 103. In alternate configurations, the port door actuation lever 222 may also be mounted to the second side 106 of the mounting plate 103. In such configurations, an operator can access the second (isolated) side 106 of the mounting plate 103 to open or close the port door 112, such as by using a glove port or automated actuator. Referring now to FIG.4, a perspective view of the second side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. In various embodiments, the port frame 102 can include a port door 112 that sealably obstructs the port opening 108 and is sealably closed against the port frame 102. As best seen in FIGS.2-3, the transfer port assembly can include a locking lever assembly 220 at the first side 104 of the transfer port system 100. The locking lever assembly 220 is configured to be actuated between the locked position to the unlocked position by rotating the locking lever handle 221 about the locking lever shaft 223 by a set degree of rotation. As depicted by FIG.4, the locking lever shaft 223 extends through at least a portion of the port frame 102 and is fixedly coupled to a locking latch 424 disposed on the second side 106 of the port frame 102. In the example of FIG.4, the locking latch 424 can include one or more cams, such as ramp 425, configured to move the port door 112 between its locked and unlocked positions when the locking lever assembly 220 is actuated. As best seen in FIGS.2-3, the transfer port system 100 can include a port door actuation lever 222, wherein actuating the port door actuation lever 222 from a first position to a second position causes the port door 112 to move from the closed position (FIG.2) to the open position (FIG.3). In the example of FIG.4, the port door actuation lever 222 extends through at least a portion of the port frame 102 and is connected to a gearbox 430 on the second side 106 of the port frame 102 and the gearbox 430 is connected to hinge shaft 432 disposed on the second side of the port frame. In the example of FIG.4, the gear box is mounted to the second side 106 of the mounting plate 103. In various embodiments, the force applied to actuate the port door actuation lever 222 on the first side 104 of the port frame is transmitted to the PDSD No.162.0046WOU1 hinge shaft 432 via the gearbox 430 and causes the hinge shaft to rotate. The hinge shaft 432 can be fixedly coupled to the port door hinge 428, which is fixedly coupled to the port door 112 by the hinge bar 426. Accordingly, actuation of the port door actuation lever 222 between its first position and its second position causes the port door 112 to rotate from its closed position to its open position (or vis versa) about its port door hinge 428. Referring now to FIGS.1 and 5, a perspective view of a mounting assembly is shown in accordance with various embodiments herein. FIG.5 depicts an example mounting assembly 110 that is similar to that depicted in FIG.1 but shown uncoupled from the transfer port assembly 101 for purposes of this discussion. The mounting assembly 110 is configured for connection with the transfer port assembly 101 at the first side 104 of the transfer port system 100for sterile transfer of a product. In various embodiments, the mounting assembly 110 has a container portion 538, a mounting assembly flange 118 configured to mount to a port frame flange 120 of a transfer port assembly 101, and a removable container cover 542. The mounting assembly 110 may also include one or more container handles (not shown in this view) configured to aid operator in mounting the mounting assembly 110 to the transfer port system 100. In various embodiments, the mounting assembly flange 118 may define a set of mounting assembly mating features 536. The mounting assembly mating features 536 can be configured to form a seal with the transfer port assembly 101, such as at the port frame flange 120. In the embodiment of FIG.5 the mounting assembly mating features 536 include three bayonet connectors configured to engage the port frame mating features 226 (configured as three bayonet receptacles in the embodiment of FIGS.2-3). In various embodiments, the one or more bayonet connectors of mounting assembly 110 are received by one or more corresponding bayonet receptacles defined by the port frame flange 120 when the mounting assembly 110 rotated relative to the port frame 102. In alternative embodiments, the mounting assembly flange 118 may include greater than or less than three bayonet connectors in any suitable configuration. The mounting assembly flange 118 may include any other suitable type of mating feature(s) in addition to or alternative to the bayonet connectors. Container portion 538 in FIGS.1 and 5 is a cylindrical wall defining an opening. The mounting assembly 110 may take a variety of forms, depending upon PDSD No.162.0046WOU1 particular transfer needs. For example, the container portion 538 could have a bag attached, could be formed as closed cylinder, or many other form factors. For example, rubber septums for vials containing injectable medications are commonly sterilized in bulk in a porous flexible bag, made of a material such as Tyvek® material made by DuPont (headquartered in Wilmington, Del., USA), and attached to a container portion of a mounting assembly. Alternatively, the mounting assembly can include a glove to permit an operator to reach into the isolated environment to permit manual operations to be performed while maintaining the integrity of the environment of the isolation chamber. In various embodiments, the removable container cover 542 defines first cover mating features 550 (e.g., bayonets) that can mate with second set of cover mating features on the port door 230 (e.g., bayonet slots), which are visible in FIG.2. Rotating the mounting assembly into engagement with the transfer port system causes the removable container cover 542 to mate with the port door and attach to it, such that when the port door is opened, the removable container cover 542 is removed from the mounting assembly, allowing access to the contents of the mounting assembly. In various embodiments, the removable container cover 542 can be replaced onto the mounting assembly when the port door is closed and locked. In various embodiments, the mounting assembly is reuseable. In various embodiments, the removable container cover 542 can also be reusable. In other embodiments, the mounting assembly 110 is intended for a single use. In various embodiments, the removable container cover 542 is replaced onto the mounting assembly 110 using fasteners that are not removable. Although the example transfer port system 100 shown in FIGS.1-5 includes a mounting plate 103, in other embodiments, the transfer port system 100 can be installed directly into a barrier wall without a mounting plate 103. The mounting plate 103 is helpful by providing the correct relative position of components including the port frame 102, the door actuation lever 222, the locking lever shaft 223, and the gearbox 430, which can aid in the installation process. However, these components can instead be installed directly into a barrier wall. Interlock Assembly (FIGS.6-9) FIGS.6-8 are front views of the first side of the transfer port system of FIG.1, including the mounting assembly 110 attached to the transfer port system, but with the PDSD No.162.0046WOU1 interlock cover portion 232 removed from the port frame 102, so that an interlock assembly 646 is visible, in accordance with various embodiments herein. FIGS.6-8 show the mounting assembly 110 and the interlock assembly 646 in different positions as the mounting assembly 110 is rotated into engagement with the interlock assembly 646. FIG.9 is a front view of the first side of the transfer port system of FIG.8, with the interlock cover portion removed, but with the locking lever assembly rotated into an unlocked position, in accordance with various embodiments herein. The interlock assembly 646 can be incorporated into the port frame 102 to enhance the safety and robustness of the rapid transfer port system 100. In various embodiments, the interlock assembly 646 is configured to prevent the port door 112 from opening when a mounting assembly 110 is not docked to the port frame flange 120. In various embodiments, the interlock assembly 646 is configured to prevent the mounting assembly 110 from being removed from the port frame flange 120 when the port door 112 is in its open position. Ensuring that the port door 112 can only be opened when a mounting assembly 110 is docked to the port frame flange 120 prevents the exposure and contamination of the contents of the mounting assembly and the isolated environment contained on the second side 106 of the transfer port system 100. In the example of FIG.6, the interlock assembly 646 can include a toggle 638 movably mounted to the port frame 102. In an embodiment, the toggle 638 can be rotatably mounted to port frame 102 about pivot fastener 640. In some embodiments, the toggle 638 can be biased into a predetermined position with biasing element 639. In various embodiments, the transfer port assembly 101 can include a locking lever assembly 220. The locking lever assembly 220 is configured to be actuated between the locked position to the unlocked position by rotating the locking lever handle 221 disposed at the first side 104 of the transfer port system 100 about the locking lever shaft 223 by a set degree of rotation. In various embodiments, the locking lever assembly 220 can further include an interlock plate 642. The interlock plate can be fixedly attached to and configured to rotate with the locking lever shaft 223. The interlock plate can define an interlock slot 644. In various embodiments, the toggle 638 is configured to selectively engage with the interlock slot 644. For instance, biasing element 639 can bias the toggle 638 such that a portion of the toggle 638 is engaged with interlock slot 644 when no other forces are acting on the toggle. In various embodiments, the locking lever assembly PDSD No.162.0046WOU1 220 is fixed in the locked position when the toggle 638 is engaged with the interlock slot 644. In the example of FIG.6, when the toggle 638 is engaged with the interlock slot, the locking lever handle 221 cannot rotate about its locking lever shaft 223 such that the port door 112 cannot be unlocked. This is due to the fact that the interlock plate 642 is fixedly attached to the locking lever shaft 223 and the presence of the toggle 638 in the interlock slot 644 prevents rotation of the interlock plate and thus prevents rotation of the locking lever handle 221 about it locking lever shaft 223. In various embodiments, the locking lever assembly 220 is configured to move between the locked position and the unlocked position when the toggle 638 is disengaged from the interlock slot 644. In various embodiments engaging the port frame mating features 226 with the mounting assembly mating features 536 causes the toggle 638 to become disengaged from the interlock slot 644, allowing for the locking lever handle 221 to rotate about it locking lever shaft 223 and for the port door 112 to be unlocked. The process of disengaging the toggle 638 from the interlock slot 644 and unlocking the port door 112 is illustrated by FIGS.7-9 herein. Referring now to FIG.7, a perspective view of the first side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. FIG. 7 includes all the features of FIG.6, but with the mounting assembly flange 118 rotated further into engagement with the port frame flange 120. In various embodiments, the mounting assembly flange 118 is mountable to the port frame 102 by virtue of the mounting assembly mating features 536 (e.g., bayonet connectors) that are configured to mate with port frame mating features 226 (e.g., bayonet slots) when the mounting assembly flange 118 is moved (e.g., rotated) into engagement with the port frame flange 120. In the example of FIG.7, as the mounting assembly flange 118 is rotated further into engagement with the port frame flange 120, one or more of the mounting assembly mating features 536 come into contact with the toggle 638. The forces transferred by the mounting assembly mating feature(s) 536 cause the toggle 638 to rotate about its pivot fastener 640 as the mounting assembly flange 118 is rotated further into engagement with the port frame flange 120. Referring now to FIG.8, a perspective view of the first side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. FIG. 8 includes all the features of FIG.7, but with the mounting assembly flange 118 being rotated further into engagement with the port frame flange 120. PDSD No.162.0046WOU1 In various embodiments, when the mounting assembly mating feature(s) 536 come into contact with the toggle 638 as the mounting assembly flange 118 is rotated into engagement with the port frame flange 120, forces are transferred to the toggle causing the toggle to rotate about a pivot fastener 640. In the example of FIG.8, the rotational motion of the toggle 638, in response to the forces applied by the mounting assembly mating feature(s) 536, causes the toggle 638 to rotate out of engagement with the interlock slot 644. In the example of FIG.8, the mounting assembly 110 has been rotated into full engagement with the port frame flange 120. In some embodiments, after reaching full engagement with the port frame flange 120, the mounting assembly flange 118 cannot be rotated any further due to the presence of one or more stop pins 848 defined in the port frame flange 120. In various embodiments, when the mounting assembly 110 is fully engaged with the port frame flange 120 and the toggle 638 is out of engagement with the interlock slot 644, the port door 112 can be unlocked with the locking lever assembly 220. Referring now to FIG.9, a perspective view of the first side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. FIG. 9 includes all the features of FIG.8, but with the locking lever assembly 220 actuated to the unlocked position. In various embodiments, when the mounting assembly 110 is fully engaged with the port frame flange 120 and the toggle is out of engagement with the interlock slot, the port door 112 can be unlocked. This is due to the fact that the interlock plate 642 is fixedly attached to the locking lever shaft 223 and without the presence of the toggle 638 in the interlock slot 644, the interlock plate (and thus the locking lever shaft) is free to rotate from the locked position to the unlocked position. In various embodiments, once the port door 112 has been unlocked with the locking lever assembly 220, the port door is configured to be actuated from its closed position to its open position with door actuation lever 222. In various embodiments, the mounting assembly 110 cannot be removed from the port frame 102 when the port door 112 is in its unlocked position. In particular, the mounting assembly mating features 536 cannot be disengaged from the port frame mating features 226 when the toggle 638 is disengaged from the interlock slot 644. This is because as the mounting assembly flange 118 is rotated out of engagement with the port frame flange 120, the toggle 638 is rotated back towards engagement PDSD No.162.0046WOU1 with the interlock slot 644. Moreover, the locking lever assembly 220 must be actuated to the locked position such that the toggle 638 can be engaged with the interlock slot 644 in order for the mounting assembly 110 to be removed from the port frame 102. Unless the toggle 638 is rotated all the way into engagement with the interlock slot 644, the mounting assembly flange 118 will not have sufficient clearance with respect to the toggle 638 to be rotated out of engagement with the port frame flange 120. Consequently, the port door 112 must be locked and in the closed position for the mounting assembly 110 to be removed from the port frame 102. FIG.10 depicts a closeup of the interlock assembly 646 of the transfer port system 100. In FIG.10, the interlock cover portion 232 has been removed from the port frame 102 to reveal the interlock assembly 646. In various embodiments the interlock assembly 646 can include a toggle 638 movably attached to port frame 102. The interlock assembly 646 can further include a locking lever assembly 220 that can include an interlock plate 642 fixedly attached to the locking lever shaft 223. The interlock plate can define an interlock slot 644. In some embodiments, the locking lever shaft 223 and the interlock plate 642 are manufactured as a unitary part. Alternatively, the locking lever shaft 223 and the interlock plate 642 can be manufactured separately and be permanently joined by any suitable process, such as welding, or the like. In various embodiments, the toggle 638 can include a pivot fastener 640 wherein the toggle is rotatably mounted to the port frame flange 120 at the pivot fastener 640 and rotates around the pivot fastener 640. In various embodiments, the toggle can further include an extension portion 1050. In various embodiments, the extension portion 1050 is designed to extend away from the pivot fastener 640 and fit within the interlock slot 644. The extension portion 1050 configured to selectively engage with the interlock slot 644. In various embodiments, toggle 638 can include a biasing element 639 configured to bias the toggle into a predetermined position. In the example of FIG.10, the biasing element 639 biases the toggle 638 such that the extension portion 1050 is engaged with the interlock slot 644 when no other forces (such as the forces applied by the mounting assembly mating features 536) are acting on to the toggle. In the example of FIG.10, the biasing element 639 takes the form of a spring with a coil PDSD No.162.0046WOU1 portion 1064 attached to and around the pivot fastener 640. The biasing element further includes a first end portion 1065 and a second end portion 1066, where at least one of the end portions 1066 is attached to the toggle. It should be appreciated that any other suitable biasing element(s) can be used in place of or additionally to the spring. In various embodiments, the toggle 638 can further include a curved profile 1052. In the example of FIG.10, the curved profile has a W-like shape, but any other suitable shape of toggle can be utilized. The curved profile 1052 can be configured to engage with the mounting assembly mating features 536. In the example of FIG.10, the curved profile 1052 can include a first protrusion portion 1054. In various embodiments, the mounting assembly mating features 536 are configured to engage with the first protrusion portion 1054 portion and cause the toggle 638 to pivot about the pivot fastener 640 and for the extension portion 1050 of the toggle 638 to be rotated out of engagement with the interlock slot 644 as the mounting assembly mating features 536 are rotated into engagement with the port frame flange 120. In various embodiments, the curved profile 1052 of the toggle can also include a second protrusion portion 1056 and a third protrusion portion 1058 with a first cavity 1060 disposed between the first protrusion portion and the second protrusion portion a second cavity 1062 disposed between the second protrusion portion and the third protrusion portion. In various embodiments, the first cavity 1060 and second cavity 1062 are configured to give the mounting assembly mating features 536 sufficient clearance to be rotated into engagement with the port frame flange 120. While the toggle 638 illustrated by the FIGS. is configured for rotational motion about pivot fastener 640, other configurations of toggle are possible. For instance, a toggle 638 can be designed to translate linearly with respect to the port frame 102 as a mounting assembly 110 is docked to the port frame 102 in order to selectively engage with an interlock slot 644, or other similar mechanism. Referring now to FIG.11, a cross-sectional view of the transfer port system of FIG.2 about section 11-11 is shown in accordance with various embodiments herein. In various embodiments, the toggle 638 can be disposed within a cavity 1168 defined within the port frame 102, such that the toggle 638 is not immediately accessible to an operator of the rapid transfer port system 100. The toggle 638 can be under the interlock cover portion 232 (FIG.2) of the port frame 102, though the interlock cover portion is removed from the view of FIG.11. PDSD No.162.0046WOU1 In various embodiments, the toggle 638 can be mounted to the port frame 102 at pivot fastener 640. The pivot fastener 640 can extend at least part of the way through the port frame 102. In the example of FIG.11, the pivot fastener 640 is threaded into the port frame 102 at threaded portion 1270 such that the pivot fastener 640 is rigidly attached to the port frame 102. In various embodiments, toggle 638 can include a biasing element 639 configured to bias the toggle into a predetermined position. In the example of FIG.11, the biasing element 639 takes the form of a spring with a coil portion 1064 that is attached to the surface of the toggle 638 around the pivot fastener 640 at a first end. The coil portion 1064 is configured to wrap around a sleeve portion 1170 of the pivot fastener 640. In various embodiments, the toggle 638 defines an aperture 1180 configured to receive the pivot fastener 640 in a configuration with sufficient clearance and interacting surfaces such that the toggle 638 is free to rotate about the pivot fastener 640. Referring now to FIG.13, a schematic front view of a toggle is shown in accordance with various embodiments herein. In various embodiments, the toggle can have a toggle length (LT). The toggle length LT as defined herein is longest length across the toggle. In some embodiments, the toggle length LTcan be greater than or equal to 50, 58, 67, or 75 mm. In some embodiments, the toggle length LTcan be less than or equal to 150, 125, 100, or 75 mm. In some embodiments, the toggle length LTcan fall within a range of 50 to 150 mm, or 58 to 125 mm, or 67 to 100 mm, or can be about 75 mm. In various embodiments, the toggle can have a toggle width (WT). The toggle length WT as defined herein is longest width across the toggle. In some embodiments, the toggle width WT can be greater than or equal to 25, 37, 48, or 60 mm. In some embodiments, the toggle width WT can be less than or equal to 125, 103, 82, or 60 mm. In some embodiments, the toggle width WT can fall within a range of 25 to 125 mm, or 37 to 103 mm, or 48 to 82 mm, or can be about 60 mm. It should be noted that the range of sizes provided in the context of FIG.13 is for exemplary purposes only. The size and relative proportions of the toggle can vary depending on several factors. For example, in some embodiments, the size of the toggle can increase with the size of the corresponding mounting assembly mating features 536. PDSD No.162.0046WOU1 In various embodiments, a front surface 1302 of the toggle 638 is a planar surface. In various embodiments, the front surface 1302 includes protrusions extending away from a planar front surface 1302.

Alternative Transfer Port (FIG.14) FIG.14 shows a perspective view of the first side of an alternative transfer port system with the mounting assembly removed and door closed in accordance with various embodiments herein. In various embodiments, the rapid transfer port system 100 can include a port frame 102 having a port frame flange 120. The port frame flange 120 can define one or more port frame mating features 226 that are configured to receive corresponding mating features of a mounting assembly (not shown in this view). In the example of FIG.14, the port frame flange 120 includes four bayonet receptacles configured to mate with four bayonet connectors of the mounting assembly. In various embodiments, transfer port system 100 can include a locking lever assembly 220. The locking lever assembly 220 can be mounted to the port frame 102 and is configured to move between a locked position (as depicted by FIG.14) wherein the port door 112 is fixed in a closed position and an unlocked position wherein the port door 112 is configured to move from the closed position to an open position. In various embodiments, the locking lever assembly 220 can further include a locking lever handle 221 and a locking lever shaft 223 extending through at least a portion of the port frame 102. In various embodiments, the locking lever handle 221 is movably PDSD No.162.0046WOU1 mounted to the port frame 102 by the locking lever shaft 223. As described in detail in the context of FIGS.2-3, the locking lever assembly 220 is actuated between the locked position and the unlocked position by rotating the locking lever handle 221 about the locking lever shaft 223 by a set degree of rotation. In various embodiments, the transfer port system 100 can include a port door 112 configured to sealably obstruct the port opening 108 against the port frame 102. In various embodiments, transfer port system 100 can include a port door actuation lever 222 mounted to the port frame 102. In various embodiments, actuating the port door actuation lever 222 from a first position (as depicted by FIG.14) to a second position causes the port door 112 to move from the closed position to the open position about the port door hinge. As described in detail in the context of FIGS.2-3, the port door actuation lever 222 is actuated from the closed position to the open position (or vice versa) by rotating the port door actuation lever 222 by a set degree of rotation. The location and shape of the port door actuation lever 222 is different in the alternative embodiment of FIGS.14-19 compared to the embodiment of FIGS.2-3. In particular, the port door actuation lever 222 of FIG.14 is mounted to the port frame while the port door actuation lever 222 of FIGS.2-3 is mounted to the mounting plate 103.However, the rotational motion of the port door actuation lever 222 to move the door between a closed position and an open position is similar in both embodiments. In various embodiments, an interlock cover portion 232 forms a part of the port frame 102 and is located over and covers a portion of the interlock assembly. The locking lever shaft 223 and the port door actuation lever 222 protrude from the interlock cover portion 232. (FIGS.15-18) FIGS.15-18 are front views of the first side of the transfer port system of FIG. 14, including the mounting assembly 110 attached to the transfer port system, but with the interlock cover portion 232 removed from the port frame 102, so that an interlock assembly 646 is visible, in accordance with various embodiments herein. FIGS.15-17 show the mounting assembly 110 and the interlock assembly 646 in different positions as the mounting assembly 110 is rotated into engagement with the interlock assembly 646. FIG.18 is a front view of the first side of the transfer port system of FIG.17, with the interlock cover portion removed, but with the locking PDSD No.162.0046WOU1 lever assembly rotated into an unlocked position, in accordance with various embodiments herein. The interlock assembly 646 can be incorporated into the port frame 102 to enhance the safety and robustness of the rapid transfer port system 100. In various embodiments, the interlock assembly 646 is configured to prevent the port door 112 from opening when a mounting assembly 110 is not docked to the port frame flange 120. In various embodiments, the interlock assembly 646 is configured to prevent the mounting assembly 110 from being removed from the port frame flange 120 when the port door 112 is in its open position. In the example of FIG.15, the interlock assembly 646 can include a toggle 638 movably mounted to the port frame 102. In an embodiment, the toggle 638 can be rotatably mounted to port frame 102 about pivot fastener 640. In some embodiments, the toggle 638 can be biased into a predetermined position with biasing element 639. In various embodiments, the locking lever assembly 220 is configured to be actuated between the locked position to the unlocked position by rotating the locking lever handle 221 about the locking lever shaft 223 by a set degree of rotation. In various embodiments, the locking lever assembly 220 can further include an interlock plate 642. The interlock plate can be fixedly attached to and configured to rotate with the locking lever shaft 223. The interlock plate can define an interlock slot 644. In various embodiments, the toggle 638 is configured to selectively engage with the interlock slot 644. For instance, biasing element 639 can bias the toggle 638 such that a portion of the toggle 638 is engaged with interlock slot 644 when no other forces are acting on the toggle. In various embodiments, the locking lever assembly 220 is fixed in the locked position when the toggle 638 is engaged with the interlock slot 644. In the example of FIG.15, when the toggle 638 is engaged with the interlock slot, the locking lever handle 221 cannot rotate about its locking lever shaft 223 such that the port door 112 cannot be unlocked. This is due to the fact that the interlock plate 642 is fixedly attached to the locking lever shaft 223 and the presence of the toggle 638 in the interlock slot 644 prevents rotation of the interlock plate and thus prevents rotation of the locking lever handle 221 about it locking lever shaft 223. In various embodiments, the locking lever assembly 220 is configured to move between the locked position and the unlocked position when the toggle 638 is disengaged from the interlock slot 644. In various embodiments engaging the port frame mating features 226 with the mounting assembly mating features 536 causes the PDSD No.162.0046WOU1 toggle 638 to become disengaged from the interlock slot 644, allowing for the locking lever handle 221 to rotate about it locking lever shaft 223 and for the port door 112 to be unlocked. The process of disengaging the toggle 638 from the interlock slot 644 and unlocking the port door 112 is illustrated by FIGS.16-18 herein. In various embodiments, the rapid transfer port system 100 can include a second interlock assembly 1546. In the example of FIGS.15-18, the second interlock assembly 1546 has a similar configuration to the interlock assembly 646. For instance, the second interlock assembly 1546 can include a second toggle 1538 that is movably mounted to the port frame flange 120 via a second pivot fastener 1540. In various embodiments, the second interlock assembly 1546 is configured to selectively restrict the port door actuation lever 222 from actuating the port door 112 from the first position to the second position. In an embodiment, the second interlock assembly 1546 is configured to ensure that the port door 112 is fully closed before the mounting assembly 110 can be disengaged from the port frame flange 120. In various embodiments, including the second interlock assembly 1546 in the rapid transfer port system 100 allows for the port door actuation lever 222 to be mounted on the port frame flange 120, reducing the overall footprint to the rapid transfer port system design. Referring now to FIG.16, a perspective view of the first side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. FIG. 16 includes all the features of FIG.15, but with the mounting assembly flange 118 rotated further into engagement with the port frame flange 120. In various embodiments, the mounting assembly flange 118 is mountable to the port frame 102 by virtue of the mounting assembly mating features 536 (e.g., bayonet connectors) that are configured to mate with port frame mating features 226 (e.g., bayonet slots) when the mounting assembly flange 118 is moved (e.g., rotated) into engagement with the port frame flange 120. In the example of FIG.16, as the mounting assembly flange 118 is rotated further into engagement with the port frame flange 120, one or more of the mounting assembly mating features 536 come into contact with the toggle 638. The forces transferred by the mounting assembly mating feature(s) 536 cause the toggle 638 to rotate about its pivot fastener 640 as the mounting assembly flange 118 is rotated further into engagement with the port frame flange 120. PDSD No.162.0046WOU1 Referring now to FIG.17, a perspective view of the first side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. FIG. 17 includes all the features of FIG.16, but with the mounting assembly flange 118 being rotated further into engagement with the port frame flange 120. In various embodiments, when the mounting assembly mating feature(s) 536 come into contact with the toggle 638 as the mounting assembly flange 118 is rotated into engagement with the port frame flange 120, forces are transferred to the toggle causing the toggle to rotate about a pivot fastener 640. In the example of FIG.17, the rotational motion of the toggle 638, in response to the forces applied by the mounting assembly mating feature(s) 536, causes the toggle 638 to rotate out of engagement with the interlock slot 644. In the example of FIG.17, the mounting assembly 110 has been rotated into full engagement with the port frame flange 120. In various embodiments, when the mounting assembly 110 is fully engaged with the port frame flange 120 and the toggle 638 is out of engagement with the interlock slot 644, the port door 112 can be unlocked with the locking lever assembly 220. Referring now to FIG.18, a perspective view of the first side of the transfer port system of FIG.1 is shown in accordance with various embodiments herein. FIG. 18 includes all the features of FIG.17, but with the locking lever assembly 220 actuated to the unlocked position. In various embodiments, when the mounting assembly 110 is fully engaged with the port frame flange 120 and the toggle is out of engagement with the interlock slot, the port door 112 can be unlocked. In various embodiments, once the port door 112 has been unlocked with the locking lever assembly 220, the port door is configured to be actuated from its closed position to its open position with door actuation lever 222. In various embodiments, the mounting assembly 110 cannot be removed from the port frame 102 when the port door 112 is in its unlocked position. In particular, the mounting assembly mating features 536 cannot be disengaged from the port frame mating features 226 when the toggle 638 is disengaged from the interlock slot 644. This is because as the mounting assembly flange 118 is rotated out of engagement with the port frame flange 120, the toggle 638 is rotated back towards engagement with the interlock slot 644. Moreover, the locking lever assembly 220 must be actuated to the locked position such that the toggle 638 can be engaged with the PDSD No.162.0046WOU1 interlock slot 644 in order for the mounting assembly 110 to be removed from the port frame 102. Unless the toggle 638 is rotated all the way into engagement with the interlock slot 644, the mounting assembly flange 118 will not have sufficient clearance with respect to the toggle 638 to be rotated out of engagement with the port frame flange 120. Consequently, the port door 112 must be locked and in the closed position for the mounting assembly 110 to be removed from the port frame 102. 22) a closeup of the interlock assembly 646 of the transfer port the interlock cover portion 232 and the locking lever handle 221 have been removed from the port frame 102 to reveal the interlock assembly 646. In various embodiments the interlock assembly 646 can include a toggle 638 movably attached to port frame 102. The interlock assembly 646 can further include a locking lever assembly 220 that can include an interlock plate 642 fixedly attached to the locking lever shaft 223. The interlock plate can define an interlock slot 644. In various embodiments, the toggle 638 can include a pivot fastener 640 wherein the toggle is rotatably mounted to the port frame flange 120 at the pivot fastener 640 and rotates around the pivot fastener 640. In various embodiments, the toggle can further include an extension portion 1050. In various embodiments, the extension portion 1050 is designed to extend away from the pivot fastener 640 and fit within the interlock slot 644. The extension portion 1050 configured to selectively engage with the interlock slot 644. In various embodiments, toggle 638 can include a biasing element 639 configured to bias the toggle into a predetermined position. In the example of FIG.19, the biasing element 639 biases the toggle 638 such that the extension portion 1050 is engaged with the interlock slot 644 when no other forces (such as the forces applied by the mounting assembly mating features 536) are acting on to the toggle. The toggle 638 can include an aperture 1954. In various embodiments, the aperture 1954 can be threaded such that a stud can be inserted into the aperture and protrude from an inner surface (the surface facing the port frame flange 120) of the toggle 638. In the example of FIG.19, the biasing element 639 takes the form of a spring and can include a portion contacting the pivot fastener 640 and another portion wound around the stud. A portion of the biasing element 639 can be bent around the pivot fastener 640. The bending of the biasing element 639 from its natural state PDSD No.162.0046WOU1 creates sufficient tension to bias the toggle 638 such that the extension portion 1050 is engaged with the interlock slot 644. In various embodiments, the toggle 638 can further include a first protrusion 1948. The first protrusion 1948 can be configured to engage with the mounting assembly mating features 536. In various embodiments, the mounting assembly mating features 536 are configured to engage with the first protrusion 1948 and cause the toggle 638 to pivot about the pivot fastener 640 and for the extension portion 1050 of the toggle 638 to be rotated out of engagement with the interlock slot 644 as the mounting assembly mating features 536 are rotated into engagement with the port frame flange 120. In various embodiments, the toggle 638 can further include a second protrusion 1950. The second protrusion 1950 can be disposed on the opposite side of the toggle 638 from the first protrusion 1948. The second protrusion 1950 can be configured to engage with the mounting assembly mating features 536 as the mounting assembly mating features 536 are rotated into engagement with the port frame flange 120. In various embodiments, the toggle 638 can further include a planar portion 1946. In various embodiments, the planar portion 1946 is not configured to engage with the second set of mating features 536 as the mounting assembly mating features 536 are rotated into engagement with the port frame flange 120.
