    Inventor: David H. Reighter
  • Method of producing electrical insulation foam
    Patent number: 4173690
    Abstract: An electrical insulation foamed plastic is produced using sulfur hexafluoride adsorbed on molecular sieves as the foaming agent and a low shear mixing technique.
    Type: Grant
    Filed: December 2, 1977
    Date of Patent: November 6, 1979
    Assignee: Gould Inc.
    Inventors: Bernard G. Giessner, David H. Reighter, Allen E. Stringfellow
  • Support insulator for gas-filled high-voltage transmission line
    Patent number: 4132855
    Abstract: A support insulator for supporting a high-voltage conductor within the interior of a gas-filled grounded housing has a generally triangular configuration, with the central bus supported within the interior of the triangle and with the apices of the triangle engaging the inner diameter of the grounded enclosure. An inner hub extending from the legs of the triangle assists in the support of the central insulator. The combination of a gas-filled high-voltage transmission line with a plurality of support insulators extending along the length of the line is disclosed.

  • High humidity resistant electrical grade polymer concrete
    Patent number: 4130536
    Abstract: Moisture absorption by polymer concrete under high humidity conditions is greatly reduced by treating the concrete aggregate with a silane.
    Type: Grant
    Filed: October 13, 1977
    Date of Patent: December 19, 1978
    Assignee: Gould Inc.
    Inventor: David H. Reighter
  • Concrete electrical insulator
    Patent number: 4126598
    Abstract: An improved electrical grade concrete insulator is prepared from a mixture of aggregate, a hydantoin epoxy resin and, optionally, cement.
    Type: Grant
    Filed: July 25, 1977
    Date of Patent: November 21, 1978
    Assignee: Gould Inc.
    Inventor: David H. Reighter
  • Method of producing an improved concrete electrical insulator
    Patent number: 4091124
    Abstract: An improved electrical grade concrete insulator is prepared by immersing a self-supporting concrete body impregnated with an uncured polymer in a liquid curable resin bath, curing said polymer, separating said body from said resin bath whereby said body has a secondary impregnation filling the voids produced when the primary impregnation shrinks on curing. The residual resin on the outside also forms a thin sealant coating on the surface of said body.
