Abstract: An example integrated support and sensor includes a longitudinal member to support an inner duct relative to an outer duct, and a sensor received within a bore of the longitudinal member and configured to collect a measurement from a flow path bounded by the inner duct.

Abstract: A system for maintaining a position of a bearing compartment in a gas turbine during disassembly of a low-pressure turbine of the gas turbine engine includes a forward annular shaft defining an engine centerline axis. The system includes a ring radially inward from and engaged with an inner diameter surface of the forward annular shaft. An aft annular shaft is radially inward from the forward annular shaft and aft of the ring. The ring is connected to a forward end of the aft annular shaft for common rotation therewith. The ring retains the aft annular shaft during disassembly. The system includes a stack nut axially held between an aft facing shoulder of the forward annular stub shaft and a forward facing surface of the ring to retain the stack nut during disassembly.

Abstract: A seal assembly may include a housing that supports a seal ring, which may be made of carbon. A radial restrictor of the assembly prevents undesired movement of any portion of the ring during assembly, and has an axially projecting protuberance rigidly engaged to one of the housing and the carbon seal ring, and a cavity defined by the other of the housing and the carbon seal ring for receipt of the protuberance. A clearance directly adjacent to and radially outward from the protuberance and within the cavity generally allows for wear of the ring and is equal to or greater than a pre-determined radial wear distance of the carbon ring seal.

Abstract: A secondary flow system provides a compact injector cooling structure for turbine blades which includes an Angled On-board Injector (AOBI) that locates a metering throat at an inward angle relative to an engine centerline. The AOBI positions the metering throat at the inward angle relative to an engine centerline to communicate cooling airflow to an angled annular section of a turbine rotor disk coverplate.

Abstract: A cross-draft spray booth is provided with an exhaust system, an air inlet and at least one columnar filtering unit. The columnar filtering unit includes a support frame, an exhaust outlet and a filtering medium in the shape of a column. The columnar filtering unit is preferably cylindrical, and utilizes non-porous filtering material.

Abstract: A tying device for tying wooden plate members, or the like, to masonry and concrete structures, including walls, floors, roofs, beams and foundations constructed of either masonry or concrete, the tying device being formed from a flat strip of bendable sheet metal stock, such as sheet metal, or the like having a part which provides an anchor portion for anchoring the tying member to a masonry or concrete structure and having another part which is slit lengthwise of the flat strip of metal stock to provide a pair of bendable tying arms which may be bent around the sides and over a portion of the top of a wooden plate member, or the like, to which the bendable tying arms may be attached by fastening means, such as nails.

Abstract: A tying device for tying a wood framing structure to a masonry block, brick or concrete surface comprising a clamping and fastening unit which includes a combination clamping and fastening member which in use is disposed outwardly of the masonry or concrete wall and is adapted to be clamped against and to be fastened to the wood framing structure. The new tying device includes a sleeve unit which is adapted to be inserted into either mortar joints or concrete and cooperates with the combination clamping and fastening unit to enable the clamping and fastening member to be moved and adjusted into and out of clamping position against a vertically extending outer wall surface of a masonry or concrete wall surface.
