Abstract: An interactive toy in accordance with the present invention includes two pair of legs extending outwardly and downwardly from either side of a body to be in contact with a surface. Each pair of legs is rotatably attached to a motor. The toy also includes a sound activation device in communication with an integrated circuit. The integrated circuit is further in communication and control of the motors such that when the sound activation device is activated, the integrated circuit controls the motors to rotate the legs. The direction of the rotation of the legs will cause the toy to move along the surface in a predefined direction, defined as forward, reverse, or spinning to the right of left.

Abstract: A chair that enables the occupant to be seated with correct posture. The chair (10) has a seat assembly (12) for supporting a person sitting on the chair. The seat assembly includes a seat frame (42) and sheet material (32) that is stretched and secured in place relative to the frame to support the weight of a person sitting on the chair by tension forces in the sheet material. The sheet material (32) includes a bead (58) along an edge thereof, the seat frame including an extruded section with a recess (56) into which the bead (58) is located. The bead (58) is secured in the recess (56) by a retaining member (60) so as to secure the sheet material (32) under tension to the seat frame (42).

Abstract: This novel cushioned container consists of an inner tube in which an item is located and concentric outer tube resiliently connected to the inner tube. The inner tube is evacuated by a hose located therein after which the hose is closed off. The outer tube is then inflated by a hose to provide a cushioning chamber surrounding the enclosed item. The hose connected to the outer chamber is then closed off to prevent air from leaving the cushioning chamber.

Abstract: This invention relates to a novel process with attendant methods and apparatus for testing interlocks on machine barrier guards or equivalent safeguards. The process simulates the breaching of the interlocked safeguard to test the interlock without shutting down the machine operation. Failed interlocks are identified and their status warned against. Furthermore, the associated barrier guards may be physically locked to prevent access to their protected space while allowing normal machine operations until maintenance is practical. The testing process makes possible the reliable interlocking of fixed guards and may be automated to prevent bypassing or sabotage of interlocked safeguarding systems.

Abstract: A system for providing a precise amount of dilution liquid to a container of concentrate to produce a reconstituted concentrate of the desired consistency. This is accomplished by introducing the liquid at a predetermined pressure controlled by a pressure regulator for a preset period set by a timed valve mechanism.

Abstract: A shelf system including a rail member and a plurality of shelf dividers. The shelf divider includes a longitudinally extending portion which has formed at its front end an integral flexible undulated C-shaped member disposed normal to the longitudinally extending portion. The divider includes at its front end a cutout whereby the divider and flexible member can be readily compressed so that the flexible member can be snap-fitted into channels formed by the rail member and the divider positioned relative thereto against accidental movement.

Abstract: A panel consisting of a first metallic sheet and a second plastic rigidifying sheet, such as a synthetic resin. The plastic sheet is adhered to the metallic sheet and is integrally molded into a plurality of irregular inverted cup-shaped elements. The cup-shaped elements are arranged to provide the sheet with the desired strength and stiffness and to accommodate components over which it is disposed.
