摘要： A large body stretcher dimensioned to accommodate large-bodied persons and foldable to conserve space. The stretcher provides a patient support surface comprising a first board and a second board that are secured together and foldable along a longitudinal axis. The stretcher may conveniently be secured, via a securing arrangement, to a host cot. The stretcher further provides rotatable backrest portions that permit the backrest of the host cot to be raised in order to assist patients who can benefit from being transported in an upright or seated position. The stretcher further provides a plurality of retaining channels so that the restraining straps of the host cot are available for use with a patient placed upon the large body stretcher. Handholds are provided to allow convenient use of the stretcher as a standalone apparatus.

摘要： An entrained particle flow turning device capable of turning entrained particle fluid flow about an abrupt turn without significant particle size and mass degradation provides significant improvement as part of a complete particle blast system. The turning base allows for preservation of independent particle mass during fluid transportation through a delivery hose ending with passage into a blast nozzle through an abrupt angular change in particle direction. The turning base allows access and confined areas for preferred ergonomic characteristics.

摘要： A turbine shroud hanger is supported from an annular outer casing and includes an annular radial flange and integral forward and aft legs at a radially inner end thereof. The legs extend axially oppositely to each other and include respective distal ends configured for supporting a plurality of arcuate shroud panels radially above a plurality of turbine rotor blades to define a tip clearance therebetween. The legs include circumferentially spaced apart forward and aft slots extending axially from the distal ends thereof toward the radial flange, and completely radially therethrough to bifurcate the legs into circumferential segments for reducing transient thermal expansion of the hanger to reduce in turn expansion of the tip clearance.

摘要： A shroud panel for a turbine shroud includes forward and aft hooks which are used to support the panel radially above a plurality of turbine rotor blades. The panel forward hook has radially outer and inner lands, with the outer land being defined by a plurality of pads circumferentially spaced apart from each other by a respective recess. The panel forward hook is sized to engage the complementary forward slot of the turbine shroud substantially concentrically therein. The pads and recess restrict flow leakage around the panel forward hook for maintaining backflow margin and improving clearance control.

摘要： A turbine shroud includes an annular outer casing having first and second radial flanges between which are suspended an adjoining annular shroud support and an annular shroud hanger. A plurality of shroud panels are joined to the shroud hanger and are positionable radially above turbine rotor blades to define a tip clearance therebetween. The four flanges are disposed in abutting contact with each other, and respective pluralities of circumferentially spaced apart first, second, and third recesses are disposed respectively between the casing first flange and the shroud flange, between the shroud flange and the hanger flange, and between the hanger flange and the casing second flange for providing radial flowpaths therebetween. The support flange and the hanger flange have respective pluralities of circumferentially spaced apart first and second metering holes extending axially therethrough for providing flow communication between the first, second, and third recesses for channeling compressor bleed air therethrough for controlling the tip clearance.

摘要： A turbine shroud includes an annular shroud support joined to an annular outer casing and spaced radially inwardly therefrom to define an annular flow duct for receiving compressor bleed air. A plurality of shroud panels are joined to the shroud support and have a radially inner surface positionable radially above turbine rotor blades to define a tip clearance therebetween. An isolation shield is joined to the shroud support radially above the panels and includes a plurality of open-ended cells facing radially outwardly in the duct toward the outer casing for inducing drag in the bleed air flowable axially through the duct to thermally isolate the shroud support from the bleed air for controlling the tip clearance.

摘要： A turbine shroud hanger includes forward and aft radially outer hooks for mounting the hanger to an annular shroud support, and forward and aft radially inner hooks for supporting a shroud panel radially above a plurality of turbine rotor blades for controlling tip clearance therebetween. The hanger forward outer hook has a radially outer land defined by a pair of pads at distal ends of the hook, with a ridge extending circumferentially therebetween. The outer land is interrupted by a central recess extending between the pads and aft from the ridge to a distal edge of the hook. The forward outer hook has a predetermined radial height which is predeterminedly larger than the radial height of the corresponding forward slot in the shroud support for effecting an interference fit at least in part at the pair of pads to provide a seal against leakage of bleed air.
