  • Restricted radiated heating assembly for high temperature processing
    Patent number: 8888917
    Abstract: A vapor deposition reactor and associated method are disclosed that increase the lifetime and productivity of a filament-based resistive-heated vapor deposition system. The reactor and method provide for heating the filament while permitting the filament to move as it expands under the effect of increasing temperature while limiting the expanding movement of the filament to an amount that prevents the expanding movement of the filament from creating undesired contact with any portions of the reactor.
    Type: Grant
    Filed: January 4, 2010
    Date of Patent: November 18, 2014
    Assignee: Cree, Inc.
    Inventors: David Todd Emerson, Robert Allen Garner, Michael John Bergmann, Keenan Carlyle Brown, Michael Allen Pennington, Thomas Goldthwaite Coleman

  • Standing valve with a curved fin
    Patent number: 6283148
    Abstract: A valve for use in a sucker rod actuated fluid pump including a traveling valve assembly and a standing valve assembly within which a vortex is believed to be created to draft the ball check valve from its seat during the stroke of the sucker rod and thereby increase the amount of petroleum fluids pumped to the surface during each stroke of the fluid pump.
