Abstract: A swing arm restraint system for an automotive lift includes a movable carriage including a swing arm mounting portion. A first swing arm restraint housing is non-rotatably connected to the swing arm mounting portion, the first swing arm restraint housing including a first internal space. A first swing arm is pivotally connected to the swing arm mounting portion and is rotatable relative to the first swing arm restraint housing. A first restraint device is located in the first internal space and connected to the the swing arm restraint housing. A second restraint device is operably connected to the first swing arm such that the second restraint device rotates with the first swing arm relative to the first swing arm restraint housing.

Abstract: A surface supported vehicle lift includes at least one independent elevating runway member which accepts loads of varying weights. The runway member accepts uniform or non-uniform loads imposed from a first end to a second end. The runway member includes at least two lift leg assemblies. The lift leg assemblies include hydraulic cylinders and a pump having an electric motor to drive the hydraulic cylinders. Each lift leg assembly also includes pulsed or proportional solenoid valves and position sensors affixed thereto. Synchronizer pumps are provided to equalize flow to and from each lift leg assembly for the runway member, and each lift leg assembly includes pulsed or proportional flow divider bias thereby maintaining lateral and longitudinal synchronization between each lift leg assembly. The surface mounted vehicle lift need not be fixedly attached to a supporting surface, and in addition, may be in moveable contact with the supporting surface.

Abstract: A shower stall featuring wall panels joined together to form a three-sided enclosure and a pair of rigid elongated hand rail members attached to opposing ones of the wall panels and extending rearward within the stall to connect to the rear wall panel. An elongated brace is attached to the outside surface of the rear wall panel and extends at least partially across the same to interconnect through the rear wall panel to each of the hand rail members.

Abstract: An automatic sequencing circuit is disclosed which recognizes a particular coded input signal, initiates a process or data operation, and provides a coded output indicative of the operation performed. The circuit is particularly suited to hardware implementation of the control graph of a directed-graph design for any equipment using digital logic circuits.
