A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.

An adjustable safety utility knife includes an elongated ergonomically shaped handle formed of two elongate shell members each having a peripheral edge and an outer generally convex surface and an inner generally concave surface. The shell members are fastened at the peripheral edges along a vertical parting plane to form an elongated internal cavity. The handle defines a front end, a back end and an intermediate portion suitable for being gripped by a user and also defining top and bottom surfaces extending along opposite sides of the shell members along the peripheral edges. The handle has a slot-like aperture at the front end substantially aligned with the parting plane and dimensioned for passage of a flat cutting blade therethrough. A guide element within the elongated cavity guides the cutting blade between a first position for safely storing the blade fully inside the cavity and a second position for selectively extending the blade beyond the aperture to expose at least a portion thereof. A manually operated button is arranged on the top surface and coupled to the guide element for selectively moving the blade between the first and second positions. The guide element includes a carriage within the elongated internal cavity for supporting a flat cutting blade and guide elements on at least one of the inner generally concave surfaces for guiding the carriage and cutting blade carried thereby between the first and second positions. The carriage includes a locking element for normally locking a cutting blade mounted thereon to substantially fix the cutting blade against relative longitudinal movements between the cutting blade and carriage. The locking element includes an unlocking element the actuation of which releases the cutting blade to permit relative longitudinal movements between the cutting blade and the carriage. A blade release element on one of the shell members actuates the unlocking element when manual force is applied thereto, whereby application of a force on the release element releases the cutting blade and enables it to be withdrawn through the front end aperture.

A front-loading, refuse collecting vehicle is modularly provided with a combination of a low-profile, front-loadable waste bin (intermediate container) and one or more, side-loading robotic arms. To reduce mechanical stresses along couplings between the vehicle and the combination of the intermediate container and the robotic arm(s), a major portion of the mass of the robotic arm mechanism is situated to the rear of the intermediate container so that a mass and beam combination is defined where the mass-supporting beam has reduced length. More specifically, hydraulic and / or other relatively massive motor means of the robotic arm mechanism are mounted to the rear of a refuse-containing wall of the intermediate container. Elastomeric and / or other dampening means may be interposed between the vehicle and the bulk mass of the combination of the intermediate container and robotic arm mechanism for converting into heat some of the vibrational energy which may otherwise move between the vehicle and the combination of the intermediate container and robotic arm mechanism. A modular sled system may be provided for supporting different robotic arms in combination with refuse containers made of different materials as may be appropriate for different waste collection situations.

The invention relates to a single-drum front loading washing machine, in particular to a door of the single-drum front loading washing machine. During washing, the drum of the single-drum front loading washing machine contains washing water, but the outer drum does not contain washing water. At present, the single-drum front loading washing machine still uses the machine door of a drum type washing machine, and the porthole of the machine door of the drum type washing machine cannot directly seal the clothes filling opening of the drum. As a result, the highest washing water level can only reach the lower edge of the clothes filling opening of the drum, so high-water level washing or rinsing cannot be performed. In the invention, a door frame 1 is openably arranged on the shell 11 of the washing machine by a hinge, the porthole 2 is fixed on the door frame by a bearing system and a shock absorbing device, or the machine door which is formed by fixedly combining the door frame and the porthole is arranged on the drum by a hinge, and thus, the porthole seals the clothes filling opening of the drum 9 when the door is closed. Therefore, the washing machine provided by the invention can perform high-water level washing or rinsing, the rinsing effect is improved consequently; and during washing, the small clothes in the drum are prevented from entering the space between the drum and an outer barrel 10 to cause a fault.

Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector. Alternatively, an iris-like structure may be incorporated into the front surface of the injector, for closing about the syringe upon insertion of the syringe into the injector.

A system and methodology for human behavior modification or maintenance implemented by electronic two way communication between a host computing device with software adapted to the task, and a user. The system employs collected data regarding user identity, availability, and behavior, and generates a customized program of sequential events during identified user available time segments on a plurality of days. The events are constantly re-allotted to the available time in given daily time segments through a feedback acknowledgment from the user subsequent to communications sent to the user about an event. This results in a constantly updated program based on user responses which continually adjusts for the remaining time in the time segment on any day during the program. The program is customizable by user input requests such as exclusion of time during the daily time segments, front loading or rear loading of daily events, program day extensions or reductions, starting a program day earlier than the regularly scheduled time, inserting plateaus to repeat days in a program, and backsetting or forwardsetting within a program profile. A shaping function may be employed to further customize the program.
