Abstract: A foot support and abduction assembly includes an abductor-mounted foot support configured for pivotal attachment proximate a foot end of a maternity bed. A calf support assembly, for mounting to the foot support, includes a housing for removably attaching the calf support to the foot support. The housing includes a spring-biased pin for releasably securing the housing to the foot support and at least one mounting stud configured for insertion into a keyhole aperture on the foot support. A calf support portion is adjustably mounted to the housing by a ball-type pivot mount. An adjustment mechanism is provided for selectively fixing the position of the calf support portion relative to the housing. The adjustment mechanism includes a slidable sleeve for locking the ball-type pivot, and a threaded rod or a cam shaft arranged to shift the slidable sleeve.

Abstract: An ink replenishment system for supplying a working solution of an ink to an electrographic imaging device. A plurality of removable ink cartridges each have at least a first compartment containing ink concentrate and a second compartment. A fluid handling system couples the first compartment of each ink cartridge to a respective working solution reservoir. A controller controls the flow of ink concentrate from each ink cartridge and liquid carrier from a source of liquid carrier to maintain a working solution concentration of working solution in each of the working solution reservoirs. A return system fluidly couples each of the developer stations to the second compartment of the respective ink cartridges. Alternate embodiments include one compartment and three compartment cartridges, and locating the working solution reservoir in the removable cartridge.

Abstract: A development apparatus for developing a latent electrostatic image on an imaging substrate in a liquid electrographic imaging system includes a cleaning roller for removing back-plated developer from a development device such as a development roller, and a squeegee apparatus for.sub.-- removing both "drip-line" developer liquid and "wrap-around" developer liquid from the imaging substrate. The squeegee apparatus may include a squeegee roller having a crowned profile and a loading mechanism configured to achieve a uniform loading force across a pressure nip formed between the squeegee roller and the imaging substrate. The cleaning roller may include a fiber cleaning media and fluid delivery means for flushing back-plated developer from the cleaning media. The development apparatus also may include means for spacing the development apparatus relative to the imaging substrate without contacting the imaging substrate, thereby avoiding disruption of the motion quality of the imaging substrate.

Abstract: An apparatus and method for removing excess developer liquid from an imaging substrate make use of a squeegee roller, and a mechanism for loading the squeegee roller against the imaging substrate. The squeegee roller removes the excess developer liquid from the imaging substrate at an upstream side of the squeegee roller relative to a direction of movement of the imaging substrate. A portion of the excess developer liquid can pass to a downstream side of the squeegee roller, however, and be transferred from the squeegee roller to the imaging substrate. A second developer liquid removal mechanism is provided to remove from the imaging substrate the portion of the excess developer liquid transferred from the squeegee roller. The second developer liquid removal mechanism may include a second squeegee roller mounted at a position adjacent the downstream side of the first squeegee roller.
