Patents by Inventor Frank E. McCown

Frank E. McCown 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).

  • Method of manufacturing thin carbon products
    Patent number: 4728535
    Abstract: Thin carbon products are produced from cellulose material by impregnation with a carbonaceous material followed by curing and baking. The baked product may optionally be graphitized depending on end use.
    Type: Grant
    Filed: June 7, 1985
    Date of Patent: March 1, 1988
    Assignee: Great Lakes Carbon Corporation
    Inventors: Louis A. Joo', Kenneth W. Tucker, Frank E. McCown, Jr.
  • Titanium diboride-graphite composites
    Patent number: 4439382
    Abstract: Titanium diboride graphite composite articles are produced by mixing TiO.sub.2, petroleum coke and a binder to form a plastic dispersion. Articles are shaped by molding or extrusion and baked to carbonize the binder to form a baked carbon-TiO.sub.2 composite. The article is impregnated with a molten or dispersed boron compound, then heated to drive TiB.sub.2 forming reaction. The article is then further heated to a graphitizing temperature to form a graphite-TiB.sub.2 composite useful as a cathode component in a Hall aluminum reduction cell.
    Type: Grant
    Filed: July 27, 1981
    Date of Patent: March 27, 1984
    Assignee: Great Lakes Carbon Corporation
    Inventors: Louis A. Joo', Kenneth W. Tucker, Frank E. McCown, Jr.
  • Titanium diboride-graphite composits
    Patent number: 4376029
    Abstract: A cathode component for a Hall aluminum cell is economically produced from a mixture of a carbon source, preferably calcined petroleum coke, and optionally calcined acicular needle petroleum coke, calcined anthracite coal; a binder such as pitch including the various petroleum and coal tar pitches; titanium dioxide, TiO.sub.2 ; and boric acid, B.sub.2 O.sub.3 or boron carbide, B.sub.4 C; forming said mixture into shapes and heating to a TiB.sub.2 -forming temperature.
