Abstract: A filter press plate shifter assembly provided with a shifter housing having a center part which passes over the filter plates and housing parts positioned adjacent opposite side rails. The housing parts are rollingly supported on rods which extend along the side rails. One housing part mounts a rotary pneumatic motor and a drive roller which drivingly engages the rod. Each housing part mounts a plate shifter unit having a pneumatic shift cylinder which is provided with relatively fixed and movable plate shifting blades. A pneumatic lift cylinder pivots the shift cylinder upwardly so that the blades project between handles of adjacent filter plates, following which the shift cylinder is energized so that the movable blade engages and shifts the endmost plate toward the open press head.

Abstract: A litter container is provided that is particularly adapted for use in urban environments. The litter container comprises an architecturally-styled, substantially cylindrical body which is bolted or otherwise suitably secured to a support surface. An arcuate door is disposed in the cylindrical body, the door comprising a substantially 180.degree. arcuate section of the cylindrical body. A hinge and mounting structure for the door is provided for pivotally mounting and cantilevering the door about a substantially vertical axis. The end of the door opposite the hinge is automatically locked in a closed or latched position by a tamper-proof latch which can only be actuated from the exterior of the litter container by a special key. A corrosion-resistant liner is disposed within the cylindrical body of the container and a chute centered on the axial centerline of the container communicates with the corrosion-resistant liner to direct litter therein.

Abstract: A heated, moist air sandwich bin for maintaining sandwiches therewithin sufficiently moist and at pre-selected appropriately elevated temperatures comprising a front always open service opening through which sandwiches may be inserted into and/or removed from the bin. A bin floor divides the bin into an upper sandwich compartment and a lower compartment and defines with the side walls of the bin air flow passages for permitting air movement between the upper and lower compartments. Blower means in the lower compartment forces moisturized air over heaters and through a discharge nozzle extending substantially across the width of and below the service opening. Air directing vanes positioned at the service opening and extending into the upper compartment direct the flow of air discharging the nozzle away from the service opening to create and maintain a dome of hot, moist air over the sandwiches while creating turbulent zones outside the dome to minimize hot, moist air escape through the service openings.

Abstract: A series of like-shelved, convertible refrigerating and heating cabinets, accessible from either one of two sides thereof through self-closing glass doors for self-service and replenishment of prepared food and drinks, and following a door opening of any duration over periods of intermittent replenishing, dispensing and storage conditions, providing fast automatic rapid air condition recovery for uniformity of refrigeration, or heating, and/or humidification of miscellaneous food products accessibly displayed.

Abstract: An easily and readily cleaned, preferably multi-tiered, freely movable, counter-top food display stand for self service which is simple in construction, easy to assemble and maintain and provides full viewability, maximizes accessibility and shields for sanitation the food displayed. The stand is preferably supported at each tier, in whole or a major part, by one leg at each end with the leg of the lowest tier disposed at the front where customer contact might occur and damage be resisted.

Abstract: The present invention relates to a food service tray slide rail drop support bracket where an accidental or intentional vertical movement of the front edge of the rail will not induce a folding or dropping of the rail below a horizontal tray-supporting position. The rear edge is lifted for lowering the front edge.

Abstract: The cabinets are equipped with elongated three-sided, flanged or webbed channels, opening downward and extending along a bottom edge. A plurality of detachable leg assemblies, having extendable feet is provided which have top plates that fit into the channels in an interlocking and mating arrangement. Holding means for each leg comprise set screws or the like that impinge against one flange of the channel and force the opposite edge or flange of the plate into the corner defined by the other flange of the channel. The legs can be inserted at intermediate or end positions along the channels at desired positions without the necessity of insertion into the open ends and sliding them longitudinally of the channels for proper placement. A modified telescoping leg assembly is also disclosed.
