  • Laminar electrical heaters
    Patent number: 4904850
    Abstract: An electrical heater which has a conductive polymer resistive element and two laminar electrodes. The electrodes are shaped and positioned such that there is a continuous margin around the periphery of the resistive element on at least one surface. The margin is particularly useful in reducing arcing which may occur between the electrodes.
    Type: Grant

  • Method for internal pipe protection
    Patent number: 4432824
    Abstract: The invention is a method and device for providing a protective coating for the inside of pipes, said method utilizing a device which is remotely actuated from outside said pipes. Specifically, the device comprises a memory metal delivery means, a corrosion resistant liner means, and a bonding means, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding means to flow progressively between the liner means and the inside of the pipe to thereby preclude air entrapment and to bond said liner means to the inside of the pipe.
    Type: Grant
    Filed: July 26, 1982
    Date of Patent: February 21, 1984
    Assignee: Raychem Corporation
    Inventors: Paul M. Cook, Richard F. Otte, James L. Claypool, Lawrence J. White, Harry C. Broyles, Peter L. Brooks
  • Apparatus for internal pipe protection
    Patent number: 4386629
    Abstract: A device for providing a protective coating for the inside of pipes, said device being remotely actuated from outside said pipes. Specifically, the device comprises a high modulus engineering plastic delivery means, a corrosion resistant liner means, and a bonding means, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding means to flow progressively between the liner means and the inside of the pipe to thereby preclude air entrapment and to bond said liner means to the inside of the pipe.
    Type: Grant
    Filed: July 7, 1981
    Date of Patent: June 7, 1983
    Assignee: Raychem Corporation
    Inventors: Paul M. Cook, Richard F. Otte, James L. Claypool, Lawrence J. White, Harry C. Broyles, Peter L. Brooks
  • Apparatus for internal pipe protection
    Patent number: 4355664
    Abstract: A method and device for providing a protective coating for the inside of pipes, said method utilizing a device which is remotely actuated from outside said pipes. Specifically, the device comprises a memory metal delivery member, a corrosion resistant liner member, and a bonding member, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding member to flow progressively between the liner member and the inside of the pipe to thereby preclude air entrapment and to bond said liner member to the inside of the pipe.
