  • Encapsulated and vented particulate thermal insulation
    Patent number: 8453393
    Abstract: An article includes a piece of encapsulated insulation including an envelope having at least two vents therethrough, a particulate insulation within the envelope, and a porous filter overlying each vent of the envelope. The porous filter has a mesh size no larger that the minimum size of the particles. The article may further include a structure having a structure surface, and the piece of encapsulated insulation overlies and covers at least a portion of the structure surface.
    Type: Grant
    Filed: August 25, 2006
    Date of Patent: June 4, 2013
    Assignees: Raytheon Company, Aspen Aerogels, Inc.

  • Pulse tube expander having a porous plug phase shifter
    Patent number: 6393844
    Abstract: A pulse tube expander includes a regenerator, a pulse tube, a porous plug phase shifter, and a surge tank, in series gaseous communication with each other. The porous plug phase shifter is made of a porous material such as a sintered mass or a packed solid bed of distinct, free-flowing bodies. The porous plug phase shifter introduces a phase shift between the pressure wave and the mass flow rate in the pulse tube expander. The porous plug phase shifter is resistant to clogging due to contamination that may be present in the system.
