Abstract: A component for a gas turbine engine, including: at least one internal cavity extending through the component, the internal cavity having at least one inlet opening and at least one outlet opening each being in fluid communication with the at least one internal cavity; a plurality of cooling features extending from a surface of the at least one internal cavity, the plurality of cooling features are formed in accordance with at least one of the following groups: i) a plurality of airfoil shaped features that extend upwardly from the surface of the at least one internal cavity and a plurality of wedge shaped features each having a triangular base that has an upstream portion and a downstream portion, the upstream portion extending further from the surface than the downstream portion; ii) a plurality features having a curved or “J” shaped base that extends upwardly from the surface, a plurality features having a double curved or symmetrically “J” shaped base that extends upwardly from the surface, and a pluralit

Abstract: An ultrasonic probe is housed in a probe housing filled with fluid under controlled pressure. The probe provides ultrasonic sound through the fluid to a bladder which presses against the interior of a rotor wall. Located along the periphery of the bladder, a fluid wiper/soaker conduit provides droplets of fluid to the wall of the rotor bore to minimize friction between the bladder and the rotor bore wall and provide an ultrasonic path between the bladder and the rotor wall.

Abstract: A combination heat shield/gasket is disposed between abutting components in a reciprocating compressor. The heat shield/gasket includes strategically located protuberances, at locations where the components do not directly abut, the tips of which contact one of the components causing the heat shield/gasket to locally deflect away from the contacted component. The deflection of the heat shield/gasket at such non-abutting locations causes a dead space to be created between the component contacted by the tip of the protuberance and the heat shield/gasket. The dead space so created is a barrier to the transfer of heat, as is the heat shield/gasket itself, from the component contacted by the protruberances to the area on the side of the heat shield/gasket opposite that side on which the dead space is created.

Abstract: A reciprocating gas compressor of the multicylinder, radial type is disclosed which includes unloading means for selectively shutting off suction gas flow to one or more of the cylinders in order to vary the capacity of the compressor. The unloading means include a valve element having a flat, planar surface which is movable between first and second positions with respect to a generally planar valve seat surrounding the inlet of the suction flow passage means, which inlet is spaced radially from the crankshaft axis and lies in a plane substantially perpendicular thereto.

Abstract: A high speed multiple section, computed-tomographic x-ray scanner is provided. The scanner utilizes a multiple-anode, scanning electron beam x-ray source to provide high speed scanning of sections of the body. No mechanical motion is involved.

Abstract: A device enabling the operator of an internal combustion engine to visually inspect the quality and level of a fluid held within an associated fluid sump of the engine, transmission, or other adjacent fluid sump. The device operates directly from the vacuum system of the associated engine to selectively draw fluid from the sump upwardly into a viewing chamber. A lamp behind the chamber illuminates the fluid to facilitate visual inspection. If the fluid is below a prescribed level, no fluid will be drawn into the chamber, thereby indicating to the operator that the fluid level is below a specified minimum. The device may also be provided with a continuous monitoring system whereby fluid may be initially drawn into the visual inspection chamber and held there indefinitely or until the fluid drops below a prescribed level. When this happens, the continuous monitoring system may function to activate an annunciator giving warning to the engine operator that the fluid level is low.
