Patents by Inventor James Joseph Pavlisin

James Joseph Pavlisin 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).

  • 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

  • Publication number: 20020142164
    Abstract: Plugs of pitch and intercalated graphite flakes that exfoliate when heated for graphite electrode joint assemblies. The plug may be inserted into the joint area of a graphite electrode assembly prior to assembly in the electrode column of an electrothermal furnace. Upon heating, the pitch melts and the treated flake exfoliates, forcing the pitch into the idle flank and void areas of the joint socket, increasing mechanical resistance, decreasing electrical and thermal resistance, and increasing joint locking mechanical strength. Also disclosed are composites comprising pitch and intercalated graphite flakes.
