Patents by Inventor David H. Buerkel

David H. Buerkel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multi-station power supply with rotary switch for connecting two stations together
    Patent number: 4733025
    Abstract: An electrical apparatus for regulating voltage polarity including a support for slidably receiving one or more carriers therein, with each carrier including circuitry. A positive and negative source of power is associated with the apparatus and each of the carriers includes connector means for coupling each carrier to the positive source of power when the carrier is in a first position, and for coupling each carrier to the negative source of power when the carrier is in a second position. In a preferred embodiment of the invention means are provided for preventing either intentional or accidental movement of the carriers from one of the first and second positions to the other position during operation of the carriers. Preferably a bridging connector is provided for coupling the circuitry of adjacent carriers to each other when the carriers are in a first position coupled to the positive source of power.
    Type: Grant
