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: An ice fishing trap comprising a main body supporting a rotatable spool for supporting a desired length of fishing line. An indicator, having both a set position and a triggered position, is supported by the main body. A release rod cooperates with the rotatable spool and, when the indicator is in its set position, and also cooperates with the indicator. The release rod has a first position in which the release rod captively retains the indicator in its set position and engages with the spool and the release rod has a second position, axially spaced from the first position, in which the release rod releases the indicator to permit the indicator to move to its triggered position, and rotation of the spool moves the release rod from its first position to its second position to actuate the indicator into its triggered position.

Abstract: A paint spray booth for painting an article and separating the spent paint overspray form the air and water used in the booth to collect the spent paint material is disclosed. The booth includes a water containing pan which has a deep portion and a shallow drain portion. The water used to separate the spent paint from the air and to clean the air discharged from the booth is collected on the drain portion and sent to the deep portion of the pan in a manner to cause a flow in the drain portion and deep portion of the pan to prevent accumulation of spent paint in undesired, inaccessible locations and to encourage movement of spent paint to desired, accessible locations in the pan and/or for removal or further treatment as by settling, skimming and/or separating, or the like, to provide the present invention with low maintenance similar to or less than other such booths, such as dry filter paint spray booths.

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 structure and a filter suitable for a paint spray booth, oven, or a combination booth and oven is described and includes outer walls enclosing the structure, only a portion of which provides the structural support for the booth's walls and roof. The interior of the booth has a plurality of filters on the walls and ceilings for supplying air from essentially the walls and ceiling to provide a more uniform air flow so that the painter is less exposed to vaporizing solvents, and when used as an oven, the heating is more uniform. Each of the filters made of a cloth material held in place by filter frames and may be used with either battens fixed to the frames or removable and held in place in pockets provided in the filter cloth.

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.
