  • Process for producing a multi-colored thermoplastic plastics foil, and a multi-colored thermoplastic plastics foil
    Patent number: 6083446
    Abstract: The invention concerns a process for producing multi-colored plastics, in which slush material is introduced into a mold which can be heated and rotated and has a molding surface. The colorant material comprises a plurality of coloring elements consisting of a colorant content and a transparent plastics cover surrounding the latter or a plastics matrix holding the colorant content together. The colorant content is left in the plastics casing or matrix during sintering and gelling.

  • Anti-theft switch for vehicles
    Patent number: 4204100
    Abstract: An anti-theft device for a vehicle that is movably mounted on wheel carriers, for securing the vehicle against theft of wheels and against unauthorized towing, which comprises an alarm switch and an actuating member, one of which is mounted in a fixed position relative to the vehicle, and the other of which is mounted to move with one of the wheel carriers. The actuating member is arranged to actuate the switch, and has sufficient lost motion relative to the switch to accommodate normal relative movement of the vehicle and the wheel carrier during travel of the vehicle. The switch is actuated by relative motion of the switch and actuating member in excess of lost motion when the vehicle is raised for towing or for removal of a wheel.

  • Switch for controlling door locks
    Patent number: 4065812
    Abstract: The switch comprises a stator which is rigidly secured to a lock cylinder case and a rotor which is rigidly fixed to a lock cylinder. The rotor rotates within the stator which has two concentric and partially overlapping circular arc conductors. The rotor drives an elliptical slip ring in a groove between the conductors and between one of the conductors and a slide surface where the conductors do not overlap. The frictional connection between the conductors and the slip ring holds the slip ring from being fully drawn out of contact with both conductors when the locking cyclinder is turned from closed to neutral position and holds the slip ring from being drawn into contact with both conductors when the locking cylinder is turned from open to neutral position.
