Mark D. Travers 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).

  • Safety flow stopper for water-cooled electrode
    Patent number: 4977576
    Abstract: A safety flow stopper in a water-cooled electric arc furnace electrode comprises a bob 16 held in place above a valve seat 12 by a release pin 17 resting on the bottom of the cavity in the nipple 20. If the electrode fails the release pin will no longer support the bob which will seat in the valve seat, shutting off the coolant flow and averting an explosion in the furnace.
    Type: Grant
    Filed: April 10, 1989
    Date of Patent: December 11, 1990
    Assignee: Great Lakes Carbon Corporation
    Inventors: Lyman T. Moore, Mark D. Travers
  • Water trap manifold for water cooled electrodes
    Patent number: 4802188
    Abstract: In a water cooled electrode assembly for an electric arc steel furnace, a water trap manifold 14 integral with the head assembly at the upper end of said electrode.
    Type: Grant
    Filed: September 26, 1985
    Date of Patent: January 31, 1989
    Assignee: Great Lakes Carbon Corporation
    Inventors: Berch Y. Karagoz, Lyman T. Moore, Mark D. Travers, Donald P. Allen
  • Scalloped nipple for water-cooled electrodes
    Patent number: 4689799
    Abstract: A water-cooled electrode for an electric arc furnace is fitted with a copper nipple 10, increased surface area through fluting or drilled or threaded passages for vastly improved cooling, joining the water-cooled and graphite portions of the electrode.
    Type: Grant
    Filed: September 27, 1985

  • Composite electrode for arc furnace
    Patent number: 4513425
    Abstract: A composite water-cooled electrode for electric arc steel furnaces comprises a tubular graphite body held in compression by means of tension stressed internal water supply pipe located between a metal header at one end and a hollow metal nipple at the other end of the electrode.
    Type: Grant
    Filed: July 15, 1983
    Date of Patent: April 23, 1985
    Assignee: Great Lakes Carbon Corporation
    Inventors: Berch Y. Karagoz, Martin M. Turban, Lyman T. Moore, Mark D. Travers
  • Composite electrode for arc furnace
    Patent number: 4490824
    Abstract: A composite electric arc furnace electrode comprises a heavy-walled tubular graphite body with a sealed inner bore, a hollow nipple, a central coolant supply pipe, and a metal header assembly. If the unit fails, it is disassembled, a new graphite main tube assembled with the metal parts, and the graphite tube consumed in the normal fashion as a tip electrode.
