  • Patent number: 8127492
    Abstract: A barrier mechanism for providing selective access to a passageway on the floor of a lobby, room or pavilion. It utilizes a frame and carriage assembly thereon, a panel which is swivelable to selectively overlie and block the passageway, and an electric motor which powers the carriage assembly and moves the panel. A group of power components, including a driver operated by the motor and other linkages on the frame, provide simultaneous translating movement of the carriage assembly and panel and swiveling of the panel, synchronized to bring about a “wrap-around” effect to the latter. Optionally, the panel can be locked in either its blocking or its access position. Important safety features are incorporated in the mechanism, to prevent inadvertent injury to passageway personnel.

  • Patent number: 5386644
    Abstract: In one preferred embodiment, a hands free hair dryer having a body in which are disposed a fan and a heating element, the body being mounted on a wall or the edge of a door. An infinitely positionable, self-supporting hose has a proximal end attached to the outlet of the body and a distal end selectively disposed to direct a stream of hot air toward the head of a user. Alternatively, the heating element may be disposed in the distal end of the hose. In another embodiment, the body is replaced with a housing within which the outlet nozzle of a conventional hand held air dryer is releasably secured.
