Patents by Inventor Greg E. Murray

Greg E. Murray 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).

  • High porosity/low permeability graphite bodies and process for the production thereof
    Patent number: 9546113
    Abstract: A method of forming a graphitic carbon body employs compression and resistance heating of a stock blend of a carbon material and a binder material. During molding of the body, resistance heating is accompanied by application of mechanical pressure to increase the density and carbonization of the resulting preform body. The preform can then be subjected to a graphitization temperature to form a graphite article.
    Type: Grant
    Filed: August 17, 2012
    Date of Patent: January 17, 2017
    Assignee: GrafTech INternational Holding Inc.
    Inventors: Chong Chen, Philip D. Coleman, Charles Irsak, Greg E. Murray, James Joseph Pavlisin, Paul Stephen Sirocky
  • Graphite electrode
    Patent number: 9497804
    Abstract: A graphite electrode exhibits oxidation resistance by modifying the outer radial surface characteristics. The outer radial surface may be modified by providing a textured portion which improves water flow while minimizing water absorbtion. Alternately, a layer of flexible graphite or plurality of particles of exfoliated graphite may be disposed on the outer radial surface of the electrode body.
