  • Patent number: 4624798
    Abstract: Electrically conductive microparticles characterized by high conductivity and low density are comprised of electrically nonconductive magnetic microballoons having an electrically conductive coating of a metal. When dispersed in an electrically nonconductive matrix, an electrically conductive composite material is formed in which the microparticles form a network of contacting particles throughout the matrix.
    Type: Grant
    Filed: February 19, 1985
    Date of Patent: November 25, 1986
    Assignee: Carolina Solvents, Inc.
    Inventors: Wayne L. Gindrup, Rebecca R. Vinson

  • Patent number: 4453140
    Abstract: A transistor oscillator circuit having a cascaded pair of transistors connected with the collector terminal of one transistor in an inverted electrical polarity so that the oscillatory period is determined by the time required for discharging a charge stored across one junction of one transistor.
    Type: Grant
