摘要： A diffuser for a centrifugal compressor has a body defining diffusing passages extending tangentially and radially from an annular space around the circumference of the compressor impeller. These passages diverge in the direction of flow and trend smoothly in cross-section from rectangular at the inlet to circular at the outlet in the preferred case. The cross-section of the passage follows the relation X/A S + Y/b s 1, WHERE X AND Y ARE COORDINATES, A AND B ARE WIDTH AND DEPTH PARAMETERS, AND S IS A SHAPE FACTOR WHICH VARIES PROGRESSIVELY ALONG THE DIFFUSING PASSAGE FROM NEAR INFINITY AT THE INLET TO PREFERABLY 2 AT THE OUTLET.

摘要： A disc-shaped member is attached to a vehicle seat and is in turn rotatably mounted on a base member secured to the vehicle floor by a conventional fore and aft seat adjuster. A locking bar has its forward end fixedly attached to the base member and is cantilevered generally longitudinally of the vehicle. The other end of the cantilevered locking bar has an upstanding projection which is engaged in a notch in the peripheral edge of the discshaped member to prevent rotation of the disc-shaped member relative the base member. An L-shaped operating lever extends laterally of the vehicle seat and has a depending leg. A first pivot pivotally mounts the depending leg on the base member, and a second pivot pivotally connects the operating lever with an integral laterally extending arm of the cantilevered locking bar. When the operating lever is pivoted about its first pivot, the second pivot is translated through an arc and the cantilevered locking bar is flexed laterally to carry the upstanding projection out of engagement of the notch and permit rotary movement of the vehicle seat. In order to minimize the vertical component of flexure of the cantilevered locking bar as the second pivot is moved through its arcuate path, the first pivot is located in a line which perpendicularly bisects the chord of the arc through which the second pivot is translated during movement of the cantilevered locking bar from its unflexed to its fully flexed position in which the seat is unlatched for rotary movement.

摘要： An improved control circuit for a commercial automatic ice cube maker of the type wherein a slab of ice is formed on a freezing plate by flowing water thereover. The circuit provides a more uniform control means that is independent of atmospheric pressure effects by means of a mercury ice thickness control thermostat switch connected between the base and emitter of a transistor, such that upon sensing a predetermined temperature of the built up ice slab the thermostatic switch opens to cause the transistor to switch ON and operating relay means to stop the water pump and close the solenoid operated defrost valve while opening second relay contacts in the thermostat switch circuit such that the system is locked in its ice slab release mode. During the ice slab release mode the mercury thermostatic switch closes while a defrosting operation of the plate causes the ice slab to release and slide onto an ice cutting grid, tripping a mercury type switch, connected from the emitter to the base of the transistor, turning the transistor OFF and causing a deenergization of the relay means thereby restarting the ice making cycle of the ice maker.

摘要： A combustion apparatus for gas turbine engines particularly adapted to reduce emissions to meet automotive requirements. The fuel is laid on the wall of a cylindrical prechamber and evaporated from the wall by combustion air which is introduced through a swirler at the upstream end of the prechamber. The inner surface of the prechamber is artificially roughened by a grid of grooves to improve fuel evaporation. The fuel is laid on the wall from an annular manifold extending around the upstream end of the prechamber through tangential orifices leading from the manifold into the interior of the prechamber. The fuel manifold is cooled and shielded from heat by an air jacket. More air enters through entrance ports distributed around the prechamber toward its downstream end. The resulting lean fuel-air mixture is delivered past an annular flow dam at the outlet of the prechamber into a combustion or reaction zone which is abruptly enlarged from the prechamber. The structure causes turbulent flow, recirculation, and good mixing in the reaction zone. A dilution zone downstream at the reaction zone has a circumferential array of dilution air ports which are of such shape as to be varied nonlinearly in area by a sliding ring valve. The sliding ring valve is coupled to a second sliding ring valve which varies the area of the air entrance ports in the prechamber in reverse sense to the dilution air ports. A pilot fuel nozzle to aid in cold starts is mounted at the upstream end of the prechamber.

摘要： A vehicle occupant restraint belt retractor in which a winding prevention mechanism responsive to belt reel rotation prevents belt winding reel rotation under the spring bias of the reel when the belt is being buckled in use position after unwinding from its fully stored condition on the reel. The mechanism includes a pawl for engaging the reel to prevent the belt winding movement thereof and a sensing member that moves under a leaf spring bias in response to the diameter of stored belt on the reel so as to control the pawl movement as a function of the length of unwound belt. The pawl is mounted on a shaft of the retractor housing in a pin and slot fashion for pivotal and limited bodily shifting movement with respect thereto and the sensing member is pivotally mounted on the same shaft. A pin and leaf spring on the sensing member are engageable with and control the pawl movement in a manner that allows belt winding reel rotation after the buckled belt is pulled from the retractor a slight amount. Secondary locking surfaces on one of the end plates of the retractor belt reel are arranged in opposed relationship to the primary locking surfaces that are selectively engaged by the retractor locking member to prevent belt unwinding reel rotation, and these secondary surfaces are where the pawl engages the reel to prevent the belt winding reel rotation.

摘要： A transmission having a torque converter with lockup clutch, hydrodynamic retarder and power shift gear unit and controls. The retarder operating chamber has toroidal flow and inlet and outlet passages providing pumping action varying as a function of toroidal flow. The main fluid supply regulated by the main regulator valve at a high pressure is connected to the gear unit controls and retarder controls. The lubrication fluid supply regulated by the lubrication regulator valve at an intermediate pressure is connected to the lubrication system. The overage from both the main and lubrication regulator valves is connected to the torque converter and in series to the cooler. The retarder manual valve in the retarder off position positions the relay valve in the off position to block the retarder chamber inlet and connect the retarder chamber outlet to exhaust and the cooler outlet to a low pressure converter regulator valve. The manual valve in the minimum to maximum retarding range of positions places the relay valve in the retarder on position connecting the retarder outlet to join the converter outlet to the cooler and the cooler outlet to the retarder inlet, disconnects cooler outlet from the low pressure regulator valve and connects retarder inlet to the retarder inlet regulator valve to regulate retarder inlet pressure between a minimum and a maximum directly as the manual valve moves from the minimum to maximum retarding position and to reduce retarder inlet pressure with increasing retarder speed to provide retarding capacity increasing as a substantially straight line function with speed.

摘要： Method and apparatus for making expanded lead grids for use in Faure-type lead-acid storage battery plates. The finished grid has a current-collecting header of unexpanded strip and a reticulated portion expanded, guillotine style, from the strip into a plurality of paste-retaining cells bounded by skeltal elements and nodes formed during expansion. The skeletal elements and nodes extend in opposite directions through the paste from substantially one face of the plate to the other and the nodes are twisted and partially flattened so as to have plateaus on the nodes which lay in planes parallel to the principal planes of the pasted plate. A ribbon or strip of lead is fed into a continuous, in-line, guillotine-type, dual expansion machine and therein expanded along its longitudinal edges to form two reticulated portions and leaving a central unexpanded portion from which a grid, header and lug are subsequently formed. The strip leaving the expanded has a V-shape or gull-winged configuration when viewed from its end, the wings of which are subsequently folded down by plow and roller means so as to be in substantially the same plane as the unexpanded portion. The reticulated portions are subsequently uniformly stretched in a direction perpendicular to the central portion by embossed forming rolls and mating counter rolls. Finally, the reticulated portion is rolled to twist and flatten the nodes joining skeletal elements. Water lubrication of the expanding dies promotes oxidation of the reticulated portion which in turn tends to enhance paste retention.
