Abstract: An automatic pet toilet has a housing defining a generally closed chamber having a floor and side walls, one of the latter having an opening through which the pet can pass. A door is displaceable on the housing between a closed position blocking the opening and an open position clear of same by means of a door drive motor. A closed-door switch on the housing generates an output only when the door is in its closed position. Floor and wall sprays respectively directed in the chamber at the floor and walls of the chamber are supplied with wash liquid, usually water, by a valve connectable to a source of pressurized liquid. A drain in the floor and a chopper connectable to a waste line receive material washed by the sprays from the walls and floor, comminute the material, and feed it to the waste line.

Abstract: A press has a flywheel and a spindle both rotatable about an axis, an axially displaceable ram and nut threadedly engaging the spindle so that rotation of the spindle axially displaces the ram, and a clutch between the flywheel and the spindle. The clutch has a housing formed with a radially open service port, a clutch plate rotationally fixed to the flywheel, and another clutch plate rotationally fixed to the spindle. One of the plates is formed with axially open cavities and one of the plates is axially movable through a relatively long stroke between an outer position with the plates spaced apart and an inner position with the plates close together. High-friction coupling elements of a predetermined axial height shorter by a working distance than the long plate stroke are seated in the cavities. The movable clutch plate can be displaced through the long axial stroke so that the clutch plates engage axially and rotationally link the spindle and flywheel.
