  • Process for producing silicon carbide fibers essentially devoid of whiskers
    Patent number: 7083771
    Abstract: Method for producing silicon carbide fibers by mixing discontinuous isotropic carbon fibers with a silica source and exposing the mixture to a temperature of from about 1450° C. to about 1800° C. The silicon carbide fibers are essentially devoid of whiskers have excellent resistance to oxidation and excellent response to microwave energy, and can readily be formed into a ceramic medium employing conventional ceramic technology. The fibers also may be used for plastic and metal reinforcement.
    Type: Grant
    Filed: July 22, 2005
    Date of Patent: August 1, 2006
    Assignee: Advanced Composite Materials Corporation
    Inventors: Derek J. Angier, James F. Rhodes, William M. Rogers

  • Neomesophase formation
    Patent number: 4184942
    Abstract: A process for increasing that fraction of an isotropic carbonaceous pitch which is capable of being thermally converted to an optically anisotropic carbonaceous pitch having less than 25 wt. % quinoline insolubles is described. Basically, the pitch is heated at elevated temperatures until spherules visible under polarized light begin to appear. Then heating is terminated and the pitch solvent extracted to provide a solvent insoluble fraction which is capable of being thermally converted to the optically anisotropic pitch.

  • Method and apparatus for energizing materials in an electric arc
    Patent number: 3931542
    Abstract: An improved apparatus and method for energizing materials in a free-burning electric arc is provided by radially disposing a plurality of anodes around an extension of the cathode axis. The anodes are inclined at an angle ranging from about 45.degree. to about 135.degree.. The current to each of the anodes is adjusted whereby the anode jets merge with the cathode jet to provide a unidirectional tail flame.
