Abstract: A hydraulic elevator system which utilizes a single hydraulic jack having a cylinder fixed below an elevator car, and a plunger. The elevator car is supported on the end of the plunger. The hydraulic jack extends upwardly and into the elevator car, reducing the space required below the car by the amount of the penetration of the hydraulic jack. The hydraulic jack is disposed adjacent to the front portion of the hatchway, enabling it to occupy an enclosed, concealed space in the elevator car, between its entranceway and its operational controls.

Abstract: An electrical switch and actuator therefor, arranged for relative movement. The switch is actuated in response to a predetermined positional relationship between the switch and actuator, with at least the mounting arrangement for the switch enabling both linear and angular adjustment of switch position. The adjustable mounting means for the switch additionally defines a wiring duct for the switch wires.

Abstract: A panel joint for joining two upstanding panel members at right angles to one another. A right angle joining member has slots which cooperate with spacers on the panel members. The spacers on at least one of the panel members include a cam surface which cooperates with a tapered transition portion of the slots in one of the leg portions of the right angle joining member, to facilitate joining panels having surfaces which may not be absolutely flat.

Abstract: A panel joint for joining first and second adjoining, upstanding wall panels such that their front surfaces are in a common plane and the forward facing corners of their adjoining edges are held tightly together. The panel joint includes first and second joint elements fixed to the back surfaces of the first and second wall panels, respectively, adjacent to their adjoining edges. The first and second joint elements each include upstanding leg portions disposed in spaced parallel relation, with one of the leg portions having a flanged end which bridges the spacing and butts against the side of the other leg portion. Clamping devices link the leg portions of the first and second joint elements.

Abstract: An elevator car including a passenger compartment having a selectable light distribution pattern through horizontally adjustable lighting fixtures and a vertically adjustable suspended ceiling which includes a light diffusing shield.
