  • Patent number: 7331612
    Abstract: A low profile tension style flexible joint for pneumatic ducting may be useful as, for example, a joint for aircraft engine pneumatic ducting. The joint of the present invention may be used at both ends of a duct that passes high temperature (up to about 1200° F.) and high pressure (up to about 110 psia) compressor air to the combustor of a turbomachine. Some turbomachines, such as the turbo engine of a jet-powered aircraft, require a very short curved duct to fit into an unusually small aircraft installation envelope. Moreover, these installations also require those features found in conventional flex joints, including being able to support the axial load inherent in pressurized ducting systems. Unlike conventional flexible joints, such as ball joints, gimble joints and pressure compensated joints, the low profile tension style flexible joint of the present invention provides a low profile, low weight design with the ability to support the axial load inherent in pressurized ducting systems.

  • Patent number: 7086653
    Abstract: The transferrable EMI gasket assembly utilizes a carrier with a pair of arms, each attached to a back panel by a hinged connection and extending in the same direction to overlie one another. The conductive, deformable gasket material is attached to the carrier and positioned adjacent the back panel. The assembly is collapsed for installation with the back panel overlying one of the arms hinged thereto to present a reduced height. The assembly is placed in the operative position by moving one arm relative to the other to pivot the carrier back panel to a near right angle position with respect to the carrier arms. In the operative position, the gasket material is compressed and deformed against the confronting surfaces to effect the EMI seal while the biasing force of the compressed gasket material, in the preferred embodiment, secures the carrier arms together.
