  • Deconsolidation device for particulate material extrusion pump
    Patent number: 8939278
    Abstract: A deconsolidation device defines a flow path with an inlet which defines a first cross-section generally equivalent to a passageway cross-section of a particulate material extrusion pump and an outlet that defines a second cross-section different than the first cross-section.
    Type: Grant
    Filed: April 13, 2010
    Date of Patent: January 27, 2015
    Assignee: Aerojet Rocketdyne of DE, Inc.
    Inventor: Mark Andrew Fitzsimmons
  • Pump apparatus including deconsolidator
    Patent number: 8851406
    Abstract: A pump apparatus includes a particulate pump that defines a passage that extends from an inlet to an outlet. A duct is in flow communication with the outlet. The duct includes a deconsolidator configured to fragment particle agglomerates received from the passage.
    Type: Grant

    Date of Patent: October 7, 2014
    Assignee: Aerojet Rocketdyne of DE, Inc.
    Inventors: Chandrashekhar Sonwane, Timothy Saunders, Mark Andrew Fitzsimmons
  • Multiple moving wall dry coal extrusion pump
    Patent number: 8439185
    Abstract: A pump for transporting particulate material includes a passageway defined on each side between an inlet and an outlet by a moving wall.
    Type: Grant
    Filed: April 13, 2010
    Date of Patent: May 14, 2013
    Assignee: Pratt & Whitney Rocketdyne, Inc.

  • Method for manufacturing a ceramic composite article
    Patent number: 8431061
    Abstract: A method for use in manufacturing a ceramic matrix composite article includes assembling a ceramic fiber sheet between a tool and a die, where the tool is conformable to the shape of the die and the melting point of the die is greater than the melting point of the tool. The assembly is then heated to soften the tool. At least one of the tool, the die or a separate inflatable member is then pressurized to conform the tool and the ceramic fiber sheet to the die. Next, the assembly is cooled and the pressure is vented before removal of the tool and ceramic fiber sheet from the die. A preceramic resin with a catalyst is then applied to the ceramic fiber sheet and cured at a curing temperature that is below the melting point of the tool, to form a preform. The tool is then removed from the preform.
