Title: Heavy duty lamp flasher unit for long vehicle - uses electric motor driving rotary switch with conductors to provide an intermittent supply to signal lamps in form of diodes
IPC: B60Q1/34
Filed: 1981-10-16
Abstract: The unit uses an electric motor driving a rotating switch to provide the intermittent electric supply to a large array of signalling lamps such as are required on a long vehicle. The device has a low heat generation of the rotating switch, allowing sustained operation at high power. A two position switch supplies a variable speed electric motor which drives a wiper past two springs placed as arcs across the circle of rotation of the wiper so that the wiper makes intermittent contact with the springs. The springs are mounted on a conductive frame which has a connecting lead to an adjustable potentiometer which is in series with the flasher lamps. An indicator lamp installed in driving compartment is connected across the supply to the lamps. Pref. the motor is of the type used to equip 2-speed windscreen wipers. The diodes can be connected to an electric cigarette lighter assembly.

Date Nov. 24, 1983.A back rest and a chair seat are pivoted to each other about a displaceable axis and the back rest is pivotally attached to a support along an axis parallel to that axis. The back rest and the seat are continuously displaceable with respect to each other between a sitting position and a recumbent position of the user. At least the displacement of the chair seat is guided at the end opposite to the axis of pivotal attachment of the seat to the back rest along a curve so determined that, when the back rest and seat undergo a displacement between the two positions mentioned above, the center of gravity of the user's body moves away from a horizontal plane over a distance which is sufficiently short to ensure that the user can modify the relative position of the back rest and seat by exerting acceptable efforts without any need to rise from the chair.
