A mechanical device and method for installing a permalloy plate

Abstract

This invention relates to the field of alloy plate installation technology, specifically a mechanical device and method for installing permalloy alloy plates. The device includes a carrier plate, with traction boxes for built-in electric hoists fixed at each of the four corners of the carrier plate's bottom surface. Steel wire ropes are wound and fixed around the electric hoists, with the bottom ends of the wire ropes detachably suspended and fixed to the corners of the alloy plate. A hydraulic cylinder is fixed inside the connecting arm, and a crossbeam slidably connected to the carrier plate is fixed to the output end of the hydraulic cylinder. In this invention, by installing four independent electric hoists on the bottom surface of the carrier plate, each electric hoist pulls the alloy plate via a steel wire rope. Simultaneous release of the steel wire ropes from two electric hoists at one end of the carrier plate allows the alloy plate to be adjusted at an inclined installation angle. When the plate surface is uneven, the downward movement of the linkage extrusion component increases the friction between it and the plate surface. Greater friction hinders the linkage extrusion component from continuing to move on the plate surface. The flatness of the alloy plate is determined by observing whether the linkage extrusion component can move on the plate surface.

Description

Technical Field

[0001] The invention relates to the technical field of alloy plate installation, in particular to a mechanical device and method for installing a Permalloy plate. Background Art

[0002] Permalloy plate refers to a plate made of Permalloy, which is a soft magnetic alloy with high magnetic permeability. It is mainly composed of two elements, iron (Fe) and nickel (Ni). Through the addition of appropriate alloying elements (such as molybdenum, chromium, copper, etc.) and heat treatment process, alloy plates with specific magnetic properties can be obtained. Permalloy usually has a face-centered cubic crystal structure, which makes it have good plasticity and processing properties;

[0003] When installing the alloy plate on the alloy frame of the lattice shell structure, it is generally necessary to first use a tower crane with an electric hoist to lift the alloy plate to the outside of the alloy frame, then release the alloy plate to the alloy frame, and then manually install and fix the alloy plate to the alloy frame of the lattice shell structure;

[0004] Traditionally, alloy plates are hoisted with only one electric hoist, which can easily cause the alloy plates to swing during the hoisting process. It is also difficult to arrange the alloy plates on the inclined mesh frame structure at a certain tilt angle, which affects the hoisting efficiency during the installation of the alloy plates. During the installation process, the alloy plates will be released outside the inclined alloy frame. Without the suspension of the electric hoist wire rope, the alloy plates are prone to slide and shift along the inclined alloy frame, which is not conducive to the precise positioning and installation of the alloy plates.

[0005] The curved surface on the outside of the lattice shell structure needs to be installed with a slightly curved alloy plate, and the inclined surface on the outside of the lattice shell structure needs to be installed with a straight alloy plate. When hoisting the straight alloy plate for installation, it is easy to mistakenly hoist the slightly curved alloy plate, resulting in the need to re-hoist the alloy plate. Most of the existing Permalloy plate installation mechanical devices do not have the function of checking whether the alloy plate is a straight alloy plate during the hoisting process, resulting in poor applicability of the installation mechanical devices. Summary of the invention

[0006] The object of the present invention is to provide a mechanical device and method for installing a Permalloy plate to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A mechanical device for installing permalloy plates, comprising a tower crane fixedly installed on a reticulated shell structure. A connecting arm is rotatably connected to the boom of the tower crane. A carrier plate is fixed to the bottom of the connecting arm. Four corners of the bottom surface of the carrier plate are each fixed with a traction box with an internal electric hoist. A steel wire rope is wound and fixed on the electric hoist. The bottom end of the steel wire rope is detachably suspended and fixed to the corner of the alloy plate. An oil cylinder is fixed inside the connecting arm. The output end of the oil cylinder is fixed with a cross beam slidably connected to the carrier plate. Linkage traction members are arranged at both ends of the cross beam. The linkage traction member includes a first connecting column embedded and fixed to the cross beam. A first gear is rotatably connected to the bottom of the first connecting column. A first rack is meshed and driven on both sides of the first gear. A telescopic assembly is fixed to the outside of the first rack. A linkage extrusion member is arranged at one end of the telescopic assembly away from the first rack. The linkage extrusion member includes a second connecting column fixedly connected to the telescopic assembly. A second gear is rotatably connected to the bottom of the second connecting column. A second rack is meshed and driven on both sides of the second gear. A rubber wheel is rotatably connected to the bottom of the second rack. A through-ring mechanism for assisting in fixing the steel wire rope to the alloy plate is fixed to the bottom of the second connecting column.

[0009] Furthermore: A circular ring is fixed to the bottom end of the steel wire rope. A hook is rotatably connected to the bottom end of the circular ring. Hoisting rings are fixed at four corner positions on the top surface of the alloy plate. Sliding columns slidably connected to the carrier plate are fixed at both ends of the top surface of the cross beam.

[0010] Furthermore: Two support blocks I rotatably connected to the first gear are fixed to the bottom of the first connecting column. Both sides of the first rack are slidably clamped to the corresponding support blocks I.

[0011] Furthermore: The telescopic assembly includes a first square tube fixedly connected to the first rack. An electric push rod is fixed inside the first square tube. The output end of the electric push rod is fixed with a second square tube slidably sleeved on the first square tube. The electric push rod is electrically connected to an external overload protector through a wire.

[0012] Furthermore: The second connecting column is fixedly connected to the corresponding second square tube. Two support blocks II rotatably connected to the second gear are fixed to the bottom of the second connecting column.

[0013] Furthermore: Both ends of the support block II are slidably clamped to the corresponding second racks. A C-shaped frame rotatably connected to the rubber wheel is fixed to the bottom end of the second rack.

[0014] Furthermore: The through-ring mechanism includes a special-shaped rod fixedly connected to the support block II. An L-shaped rod I is meshed and driven inside the special-shaped rod. An L-shaped rod II is meshed and driven on the outside of the special-shaped rod.

[0015] Furthermore, the inside and the outside of the special-shaped rod are rotatably connected with gear three via a rotating shaft, the outsides of the L-shaped rod one and the L-shaped rod two are embedded with fixed rack three, the rack three is meshed with gear three at the corresponding position for transmission, and the outside of the special-shaped rod is fixed with a limit rod slidably connected with the L-shaped rod two.

[0016] Further, an arc groove is formed on the top surface of the L-shaped rod, a rectangular groove is formed on one end of the special-shaped rod, two rubber blocks are fixed on the inner side of the rectangular groove, and notches are formed on both sides of the hook.

[0017] The present invention also provides a method for installing a mechanical device for a Permalloy plate, the method specifically comprising the following steps:

[0018] Step 1: The tower crane transfers the carrier plate to the top of the alloy plate through the boom, and the oil cylinder moves the crossbeam downward so that the linkage traction part moves the linkage extrusion part downward;

[0019] Step 2: The rubber wheels on the linkage extrusion piece abut against the two ends of the middle of the plate surface, and the output end of the electric push rod extends to move the linkage extrusion piece toward the lifting ring of the alloy plate;

[0020] Step 3: If the two ends of the board are not level, the linkage extrusion piece at a higher position will push the rack 1 upwards, and the other rack 1 will drive the other linkage extrusion piece to squeeze the board surface under the transmission of the gear 1, so that the resistance between the board surface and the linkage extrusion piece is larger, which prevents the rubber wheel from continuing to roll along the board surface;

[0021] Step 4: Observe whether the rubber wheel rolls on the plate surface to determine whether the alloy plate meets the straight installation requirements. If the rubber wheel cannot roll, it means that the alloy plate does not meet the requirements;

[0022] Step 5: When the board surface is straight, the linkage extrusion piece will move smoothly to the lifting ring position, and the ring-threading mechanism will hook the hook to the lifting ring;

[0023] Step 6: The electric hoist reels the wire rope to make multiple hooks lift the alloy plate, and the tower crane suspends the alloy plate to the installation location;

[0024] Step 7: The oil cylinder moves the crossbeam downward again, and multiple linkage extrusion parts squeeze and fix multiple corners of the alloy plate to assist in the manual installation of the alloy plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Electric hoists are installed and fixed at the four corners of the bottom surface of the carrier plate. Each electric hoist is hung on the lifting ring of the alloy plate through the hook on the wire rope. The boom of the tower crane can move the carrier plate to different positions through the connecting arm, and then the carrier plate is transferred to the upper part of the to-be-installed position on the lattice shell mechanism through the electric hoist and the wire rope with the alloy plate. The two electric hoists at one end of the carrier plate can be rotated at the same time to release the wire rope, and the two electric hoists at the other end of the carrier plate can be rotated at the same time to reel in the wire rope, so that the alloy plate can be adjusted to an inclined state to adapt to the inclined alloy frame. By fixing four independent electric hoists on the bottom surface of the carrier plate, the multi-angle lifting of the Permalloy plate and the installation at different angles on the working surface can be realized. During the transportation of the alloy plate, the four corners of the alloy plate are all pulled and restrained by the independent wire ropes, which can keep the alloy plate in a stable moving position.

[0027] 2. Drive the crossbeam with the connecting column to move toward the alloy plate through the output end of the oil cylinder. The rack gear with meshing transmission on the outside of the connecting column moves downward with the linkage extrusion part through the telescopic assembly, so that the rubber wheel contacts the alloy plate (refer to the instruction manual). Figure 4 ), the output end of the electric push rod drives the connecting column on the linkage extrusion piece to move in the direction of the lifting ring (refer to the instruction manual Figure 5 ), the connecting column 2 rolls along the surface of the alloy plate with two racks 2 and the rubber wheel at the bottom of the racks 2. When the alloy plate is bent and the surface heights of the two ends are different, the higher curved convex surface at one end of the alloy plate will push the rubber wheel upwards, so that the connecting column 2 above the rubber wheel moves up with a rack 1 through the telescopic component, and the other rack moves down or has a tendency to move downward under the meshing transmission of the gear 1. The downward thrust will be transmitted to the rubber wheel of the other connecting column 2 through another telescopic component. The rubber wheel at this position will increase the resistance of the electric push rod output end to extend and push the connecting column 2 to move because of excessive compression with the alloy plate;

[0028] The overload protector electrically connected to the electric push rod will automatically cut off the power of the electric push rod when the resistance at the output end of the electric push rod is greater than the preset value, thereby stopping the second connecting column and the rubber wheel from moving on the board surface. By observing whether the second electric push rod can drive the rubber wheel on the second connecting column to move on the board surface, it can be indirectly judged whether the alloy plate is a straight alloy plate, so as to pre-check whether the alloy plate is the required straight alloy plate before lifting the alloy plate.

[0029] 3. There are two racks 2 meshingly driven on the outside of gear 2 at the bottom of connecting column 2. The bottom ends of the two racks 2 are rotatably connected with rubber wheels. When the two rubber wheels roll along one end of the board at the same time, if a local area of ​​one end of the board is bent or concave, a rubber wheel on the linkage extrusion piece will push rack 2 upward. Under the meshing transmission of gear 2, the other rack 2 on the linkage extrusion piece moves down with the rubber wheel to extrude the board, thereby increasing the resistance of the linkage extrusion piece to move on the board, and also triggering the overload protector to cut off the power to the electric push rod, thereby determining that the board is uneven, so that the two linkage extrusion pieces can cooperate to detect whether the two ends of the board are straight, and a single linkage extrusion piece can detect whether one end of the board is straight.

[0030] 4. When the connecting column 2 rolls along the plate surface with the rubber wheel to detect whether the plate surface is straight, the connecting column 2 will move the hook connected to the end of the special-shaped rod toward the direction of the lifting ring. After the hook passes through the lifting ring, the L-shaped rod 2 contacts the lifting ring. At this time, the special-shaped rod continues to move toward the lifting ring along with the connecting column 2. The lifting ring will push the L-shaped rod to rub the outer gear 3 of the special-shaped rod to rotate. The rotation of the gear 3 on the outer side of the special-shaped rod drives the inner gear 3 of the special-shaped rod to rotate synchronously (the two gears 3 are fixed on the same rotating shaft). The inner gear 3 of the special-shaped rod drives the L-shaped rod 1 to move up, and the L-shaped rod 1 drives the hook to move up, so that the hook can move up automatically after passing through the lifting ring to prevent the hook from detaching from the lifting ring, eliminating the need to manually install the hook to the lifting ring position, which is beneficial to improving the efficiency of the installation and connection between the wire rope and the alloy plate.

[0031] 5. After releasing the alloy plate onto the inclined alloy frame, the output end of the oil cylinder can move toward the alloy plate with the connecting column, and the connecting column moves downward with the telescopic assembly through two racks, and the telescopic assembly moves downward with the linkage extrusion piece (refer to the instruction manual Figure 6 ), the two racks move away from each other so that the two linked extrusions can adapt to the inclined arrangement of the alloy plate and press it on the surface of the alloy plate, so that the surface of the alloy plate near the four corners is squeezed by the independent linked extrusions, which effectively prevents the alloy plate from moving in the inclined installation position and is conducive to the accurate installation and fixation of the alloy plate to the alloy frame.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] For example, see Figures 1 to 10In an embodiment of the present invention, a mechanical device for installing a permalloy plate includes a tower crane 200 installed and fixed on a lattice shell structure 100, a connecting arm 210 is rotatably connected to the boom of the tower crane 200, a carrier plate 300 is fixed to the bottom of the connecting arm 210, a traction box 310 with a built-in electric hoist is fixed to the four corners of the bottom surface of the carrier plate 300, a steel wire rope 311 is wound and fixed on the electric hoist, the bottom end of the steel wire rope 311 is detachably suspended and fixed to the corner of the alloy plate 400, an oil cylinder 211 is fixed inside the connecting arm 210, a crossbeam 320 slidably connected to the carrier plate 300 is fixed to the output end of the oil cylinder 211, and linkage traction members 500 are provided at both ends of the crossbeam 320, and the linkage traction member 500 includes a crossbeam 320 and a crossbeam 320. A connecting column 510 is embedded and fixed, and the bottom of the connecting column 510 is rotatably connected to a gear 520, and both sides of the gear 520 are meshed and transmitted with a rack 530, and a telescopic component 600 is fixed to the outer side of the rack 530, and a linkage extrusion component 700 is provided at the end of the telescopic component 600 away from the rack 530. The linkage extrusion component 700 includes a connecting column 2 710 fixedly connected to the telescopic component 600, and the bottom of the connecting column 2 710 is rotatably connected to a gear 2 720, and both sides of the gear 2 720 are meshed and transmitted with a rack 2 730, and the bottom of the rack 2 730 is rotatably connected to a rubber wheel 740, and a ring-threading mechanism 800 for assisting the fixation of the steel wire rope 311 and the alloy plate 400 is fixed at the bottom of the connecting column 2 710.

[0045] Specifically, four independent electric hoists are installed on the bottom of the carrier plate 300, and each electric hoist pulls the alloy plate 400 through the wire rope 311, so that the alloy plate 400 is more stable during transportation. The two electric hoists at one end of the carrier plate 300 release the wire rope 311 at the same time to adjust the inclined installation angle of the alloy plate 400. When it is necessary to take a straight alloy plate 400, the oil cylinder 211 drives the connecting column 1 510 on the crossbeam 320 to move downward, and the two meshing transmission racks 1 530 on the outer side of the connecting column 1 510 are brought into contact with the plate surface through the telescopic component 600 with the linkage extrusion piece 700, and the length of the telescopic component 600 is extended to make the linkage extrusion piece 700 The rubber wheel 740 can roll along the plate surface. When the two ends of the plate surface are bent at different heights, the higher end of the plate surface will move up with a rack 530 through the linkage extrusion piece 700, and the other rack 530 will move down with another linkage extrusion piece 700 under the transmission of the gear 520. The downward movement of the linkage extrusion piece 700 will increase the friction between it and the plate surface. The larger friction force will hinder the linkage extrusion piece 700 from continuing to move on the plate surface. By observing whether the linkage extrusion piece 700 can move on the plate surface, it is judged whether the alloy plate 400 is straight, so as to pre-check whether the alloy plate 400 is the required straight alloy plate 400 before hoisting the alloy plate 400.

[0046] like Figure 2-4As shown, in this embodiment, a circular ring is fixed to the bottom end of the wire rope 311, and a hook 3111 is rotatably connected to the bottom end of the circular ring. Hanging rings 410 are fixed to the four corners of the top surface of the alloy plate 400, and sliding columns 321 slidably connected to the carrier plate 300 are fixed to both ends of the top surface of the beam 320.

[0047] In this embodiment, the hook 3111 is hung on the lifting ring 410, and the electric hoist 311 of the prior art is used to reel in the wire rope 311 to lift the alloy plate 400. During the lifting process, the connecting arm 210 can be rotated on the lifting arm to adjust the lifting direction, and the lifting arm can swing up and down to adjust the pitch direction. The height control of the tower crane 200 itself also facilitates the large-scale height control of the alloy plate 400, thereby enabling the alloy plate 400 to be transferred to the installation position. The specific working principle of the tower crane 200 is the prior art and is not elaborated here. The sliding column 321 enables the beam 320 to move stably up and down on the carrier plate 300.

[0048] like Fig. 9 As shown, in this embodiment, two support blocks 511 are fixed to the bottom of the connecting column 510, both of which are rotatably connected to the gear 520. The two sides of the rack 530 are slidably engaged with the support blocks 511 at the corresponding positions, so that the two racks 530 can mesh and move in directions away from each other at the same time, and the rack 530 can stably slide up and down on the outside of the connecting column 510 without being separated from the connecting column 510.

[0049] like Figure 6 and Fig. 9 As shown, in this embodiment, the telescopic assembly 600 includes a square tube 610 fixedly connected to a rack 530, an electric push rod 620 is fixed inside the square tube 610, a square tube 2 630 slidably sleeved with the square tube 610 is fixed at the output end of the electric push rod 620, and the electric push rod 620 is electrically connected to an external overload protector through a wire.

[0050] In this embodiment, the extension or shortening of the output end of the electric push rod 620 can enable the square tube 2 630 to move on the plate surface with the linkage extrusion part 700, so that the linkage extrusion part 700 can detect whether the plate surface is straight. When the resistance encountered by the movement of the linkage extrusion part 700 is large, the output end of the electric push rod 620 needs to overcome the large resistance to complete the driving of the linkage extrusion part 700 to move. At this time, the overload protector will automatically cut off the power to the electric push rod 620 to prompt that the movement resistance of the linkage extrusion part 700 is large, thereby reflecting that the alloy plate 400 is uneven. The overload protector is a prior art and the specific working principle will not be elaborated here.

[0051] like Fig.10As shown, in this embodiment, the second connecting column 710 is fixedly connected to the corresponding square tube 630. Two second supporting blocks 711 are fixed to the bottom of the second connecting column 710, and both are rotatably connected to the second gear 720. Thus, the telescopic assembly 600 can move the second connecting column 710, and the second supporting blocks 711 enable the second gear 720 to rotate stably at the bottom of the second connecting column 710.

[0052] As Fig.10 shown, in this embodiment, both ends of the second supporting block 711 are slidably clamped to the corresponding second rack 730. A U-shaped frame 731 rotatably connected to the rubber wheel 740 is fixed to the bottom end of the second rack 730. Thus, the second rack 730 can move up and down stably outside the second connecting column 710 without separating from the second connecting column 710.

[0053] During specific implementation, the spare alloy plate 400 is pre-placed on an external support table. The tower crane 200 transfers the carrier plate 300 to directly above the alloy plate 400 through the boom. The oil cylinder 211 drives the cross beam 320 to move downward, so that the linkage traction member 500 drives the linkage extrusion member 700 to move downward through the telescopic assembly 600. The rubber wheels 740 on the linkage extrusion member 700 abut against both ends of the middle part of the plate surface (refer to the specification Figure 4 ). The output end of the electric push rod 620 extends to extend the overall length of the telescopic assembly 600. The square tube 630 drives the linkage extrusion member 700 to move towards the lifting ring 410 of the alloy plate 400. If the two ends of the plate surface are not flat, the linkage extrusion member 700 at the higher position will push the first rack 530 upward. The other first rack 530 drives the other linkage extrusion member 700 to extrude the plate surface under the transmission of the first gear 520, so that the resistance between the plate surface and the linkage extrusion member 700 is large, hindering the rubber wheels 740 from continuing to roll along the plate surface. By observing whether the rubber wheels 740 roll on the plate surface, it is judged whether the alloy plate 400 meets the flat installation requirements. When the plate surface is flat, the linkage extrusion member 700 will smoothly move to the position of the lifting ring 410, and the hook 3111 is hung on the lifting ring 410 through the ring-passing mechanism 800. Then, the electric hoist winds the steel wire rope 311 to lift the alloy plate 400 with multiple hooks 3111. At the same time, the oil cylinder 211 drives the cross beam 320 to move upward, so that multiple linkage extrusion members 700 are separated from the alloy plate 400. After the tower crane 200 suspends the alloy plate 400 to the installation position, the oil cylinder 211 can drive the cross beam 320 to move downward again, so that multiple linkage extrusion members 700 extrude and fix multiple corners of the alloy plate 400 to assist in the manual installation of the alloy plate 400. When the flat alloy plate 400 is not needed, multiple independent electric hoists can be directly used to cooperate to suspend the alloy plate 400, saving the work process of detecting the flatness of the alloy plate 400.

[0054] Embodiment 2, on the basis of Embodiment 1, in order to assist in hanging the hook 3111 on the lifting ring 410.

[0055] like Figure 7 As shown, in this embodiment, the ring-threading mechanism 800 includes a special-shaped rod 810 fixedly connected to the supporting block 2 711, the special-shaped rod 810 is internally meshed with an L-shaped rod 1 820, and the outer side of the special-shaped rod 810 is meshed with an L-shaped rod 2 830. The inside and the outside of the special-shaped rod 810 are both rotatably connected to a gear 3 811 via a rotating shaft, the outer sides of the L-shaped rod 1 820 and the L-shaped rod 2 830 are both embedded in a fixed rack 3 821, the rack 3 821 is meshed with the corresponding position gear 3 811 for transmission, and the outer side of the special-shaped rod 810 is fixed with a limit rod 812 that is slidably connected to the L-shaped rod 2 830.

[0056] In this embodiment, the L-shaped rod 1 820 and the L-shaped rod 2 830 are both slidably connected on the special-shaped rod 810, and are jointly meshed with two synchronously rotating gears 3 811 for transmission. When the L-shaped rod 2 830 is pushed by the lifting ring 410 and rotates with the gear 3 811, the gear 3 811 will move the L-shaped rod 1 820 upward, and then the L-shaped rod 1 820 will move up with the hook 3111 passing through the lifting ring 410, so that the hook 3111 is firmly connected to the lifting ring 410.

[0057] like Figure 7 and Figure 8 As shown, in this embodiment, an arc groove is formed on the top surface of the L-shaped rod 820, a rectangular groove is formed at one end of the special-shaped rod 810, two rubber blocks 813 are fixed inside the rectangular groove, and notches 3111a are formed on both sides of the hook 3111.

[0058] When the hook 3111 passes through the ring 410, the wire rope 311 is lifted up to make the hook 3111 leave the rectangular groove. The notch 3111a on the hook 3111 is convenient for increasing the contact area between the hook 3111 and the rubber block 813, so that the hook 3111 initially placed in the rectangular groove is more stable. When the rubber wheel 740 contacts the plate surface, there is still a gap between the L-shaped rod 820 and the plate surface. The sum of the gap distance and the distance that the L-shaped rod 820 can move upward satisfies that the special-shaped rod 810 will not contact the plate surface when the linkage extrusion piece 700 presses the inclined alloy plate 400 in the later stage.

[0059] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0060] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
