    Date of Patent: August 17, 1993
    Assignee: W. L. Gore & Associates, Inc.
    Inventor: Vu A. Lai
  • Non-metal high resistance electric cable
    Patent number: 5101190
    Abstract: A non-metal controlled high resistance electric cable formed by wrapping a center strength member of insulating microporous polytetrafluoroethylene with a narrow strip of conductive carbon-filled microporous polytetrafluoroethylene and jacketing the wrapped strand with an insulating microporous polytetrafluorethylene or polyester jacket. The microporous polytetrafluorethylene layers are preferably sintered and the optional polyester layer is preferably fused.

  • Retractable coiled electrical cable
    Patent number: 4988833
    Abstract: A retractable coiled cable having a retractable member imbedded in the jacket of the coiled cable so as to utilize space between adjacent coil turns of the coiled cable, allowing the adjacent coil turns of the coiled cable to fit together with no increase in diameter over that of a coiled cable having no retractable member.
