Owen W. Johnson 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).

  • Electrically conductive and corrosion resistant current collector and/or container
    Patent number: 4483785
    Abstract: An improved electrically conductive current collector suitable for use in high temperature applications in the presence of corrosive environments comprising: (A) a high strength, noncorrosive electronically conductive ceramic member which serves as the primary load bearing element for said current collector; and (b) a highly electronically conductive metal cladding intimately attached to a substantial portion of ore surface of said ceramic member and adapted to direct current flow through said ceramic member and to shunt said current between said member and an external contact. The disclosed current collectors are ideally suited for use as current collectors and current collector/containers for electrical conversion devices such as the sodium/sulfur battery and the like. Also disclosed are two processes for preparing tantalum or niobium doped rutile titanium dioxide.
    Type: Grant
    Filed: January 8, 1979
    Date of Patent: November 20, 1984
    Assignee: University of Utah Research Foundation
    Inventors: Owen W. Johnson, Gerald R. Miller, Paul S. Beutler
  • Electrically conductive and corrosion resistant current collector and/or container
    Patent number: 4160069
    Abstract: An improved electrically conductive current collector suitable for use in high temperature applications in the presence of corrosive environments comprising: (A) a high strength, noncorrosive electronically conductive ceramic member which serves as the primary load bearing element for said current collector; and (b) a highly electronically conductive metal cladding intimately attached to a substantial portion of one surface of said ceramic member and adapted to direct current flow through said ceramic member and to shunt said current between said member and an external contact. The disclosed current collectors are ideally suited for use as current collectors and current collector/containers for electrical conversion devices such as the sodium/sulfur battery and the like.
