  • Patent number: 10508759
    Abstract: A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system.

  • Patent number: 10208673
    Abstract: A fluid dispensing apparatus that may be additive manufactured as one unitary piece and may be a fuel injector for a gas turbine engine includes a radial displacement bellows having an outer surface that faces and may be exposed to a surrounding environment and an interior surface that faces and may define at least in-part a flowpath extending along a centerline. The radial displacement bellows is constructed and arranged to move between an expanded state when a pressure differential between the environment and the flowpath is low to a restricted state when the pressure differential is high.

  • Patent number: 7544900
    Abstract: Raceway modules of predetermined length are joined by couplers designed to allow optional gaps between the T-shaped raceway base plate portions. Upper and lower L-shaped raceway covers are separately snapped out the base, allowing electrical and data/communication devices to be provided in staggered relationship, and anywhere along the raceway. The lower L-shaped raceway cover configuration allows outlet devices to be provided in the lower side of the raceway. The T-shaped base plate has pre-punched knock-out openings and mounting holes provided in a predetermined pattern, and pre-punched lines of weakening, that simplify the installation process. The couplers come in several lengths and configurations, to bridge crossing raceway or other obstructions, and to provide continuity in the gaps between the raceway modules. Pre-wired cover components are fitted with spaced outlet devices for installation in areas of a room that require such service.
