Patents by Inventor Gerald P. Kehrer

Gerald P. Kehrer 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).

  • Base member coated with an electrically conductive silicone elastomer
    Patent number: 4303735
    Abstract: It has been discovered that the addition of a small amount (less than 5 percent by weight) of chopped graphite fibers to an electrically conductive silicone elastomeric mixture increases the electrical conductivity to an unexpected degree. The electrically conductive silicone elastomeric mixture can be coated on a base member and cured to yield an electrically conductive device.An application of the technology is the manufacture of conductive core for use in automotive ignition cable. By using this electrically conductive silicone elastomeric mixture it is no longer necessary that the base member itself be conductive.
    Type: Grant
    Filed: September 2, 1980
    Date of Patent: December 1, 1981
    Assignee: Dow Corning Corporation
    Inventors: Gerald P. Kehrer, William G. Smith
