Patents by Inventor Jeffrey C. Leder

Jeffrey C. Leder 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).

  • Electrical devices comprising conductive polymer compositions
    Patent number: 4876440
    Abstract: In order to increase the stability of a device comprising at least one electrode and a conductive polymer composition in contact therewith, the contact resistance between the electrode and the composition should be reduced. This can be achieved by contacting the molten polymer composition with the electrode while the electrode is at a temperature above the melting point of the composition. Preferably, the polymer composition is melt-extruded over the electrode or electrodes, as for example when extruding the composition over a pair of pre-heated wires.
    Type: Grant
    Filed: February 7, 1989
    Date of Patent: October 24, 1989
    Assignee: Raychem Corporation
    Inventors: Hundi P. Kamath, Jeffrey C. Leder
