Richard M. Westfall 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).

  • Electrolytic preparation of tin, other metals, alloys and compounds
    Patent number: 5215631
    Abstract: Electrolytic processes for the growth of crystalline tin or other elemental crystals, with or without the use of a substrate. Exemplified cubic forms of alpha-tin and tetragonal forms of beta-tin are grown using a shaped anode and a pointed cathode to provide electrical geometric fields within an electrodeposition system to enhance the growth of the desired crystalline tin.
    Type: Grant
    Filed: October 11, 1991
    Date of Patent: June 1, 1993
    Assignee: Cel Systems Corporation
    Inventor: Richard M. Westfall
  • Electrolytic preparation of tin and other metals
    Patent number: 4826579
    Abstract: Electrolytic processes for the growth of single crystal tin or other elemental crystals, with or without the use of a substrate. Exemplified cubic forms of alpha-tin and tetragonal forms of beta-tin are grown using a shaped anode and a pointed cathode to provide electrical geometric fields within an electrodeposition system to enhance the growth of the desired crystalline tin.
    Type: Grant
    Filed: December 24, 1986
    Date of Patent: May 2, 1989
    Assignee: Cel Systems Corporation
    Inventor: Richard M. Westfall
  • Electrolytic preparation of tin
    Patent number: 4632736
    Abstract: Electrolytic processes for the growth of single crystal tin or other elemental or compound cystals, with or without the use of a substrate. Cubic forms of alpha-tin and tetragonal forms of beta-tin are grown using a shaped anode and a pointed cathode to provide electrical geometric fields within an electrodeposition system to enhance the growth of the desired crystalline tin.The single crystal cubic tin is preferred because it provides an excellent epitaxial substrate for the deposition of various binary, ternary, and quaternary semiconductors. Combinations of the cubic alpha-tin with the present binary and ternary semiconductors in several forms of photovoltaic cells and infrared detectors are set forth.
