  • Covering for improving worn out steps
    Patent number: 4783939
    Abstract: The covering (20) for repairing worn-out steps has two unitary flanges (21, 22, 25, 29) linked together, and is made of step and scuff resistant plastic. At least the capping (21) comprises at its underside facing the step (10) an insert of press board, which has less specific weight as the plastic (23) of the covering (FIG. 1).
    Type: Grant

    Date of Patent: November 15, 1988
    Assignee: Freiher von Kunssberg Vertriebsgesellschaft GmbH
    Inventors: Gunther Bergmann, Florestan F. V. Kunsberg
  • Two terminal circuitry for voltage limitation
    Patent number: 4323792
    Abstract: A two terminal solid state device for voltage limitation comprises a controllable current path and a control electrode for the control thereof. A series arrangement of one or more diodes is connected with one of the ends thereof to said control electrode and with the other end thereof to one of said two terminals of the device. The latter is adapted to operate above the combined threshold voltages of said controllable current path and that of said one or more diodes.

    Inventors: Gunther Bergmann, Arthur Kessler
  • Circuit arrangement for operating electromechanical switching devices
    Patent number: 4266150
    Abstract: A circuit for operating an electromechanical switching mechanism in response to steep-edged electrical stepping pulses, including a pulse shaping stage connected between the source of such stepping pulses and the switching mechanism to convert the stepping pulses into a stepping signal having edges of reduced steepness.

  • Method of manufacturing an integrated circuit including an analog circuit and an I.sup.2 L circuit utilizing staged diffusion techniques
    Patent number: 4197147
    Abstract: A method of manufacturing an integrated circuit including an analog circuit and an I.sup.2 L circuit which both contain NPN transistors on a P-type semiconductor chip in which the method includes an N.sup.+ diffusion step for producing a flat diffusion for certain NPN transistors having smaller penetration depth than N.sup.+ regions of the other NPN transistors for connection of an emitter electrode to the said certain NPN transistors.
