摘要： A dispenser and component feeder for integration with automated assembly equipment is adapted for the high speed placement of self-orienting components of varying sizes and includes, a linear vibratory chute for transferring the self-orienting components from the storage hopper to an adjustable single roller feed assembly where the self-orienting components are conveyed to a pick-up position, the single roller feed assembly having a roller to facilitate in conveying the self-orienting components, and alternately reciprocating rod members to segregate a self-orienting component at the pick-up position. A pick-up and placement assembly is operative to pick-up the segregated self-orienting component from the pick-up position and move the same to a position for placement on an associated conveyor on the automated assembly equipment.

摘要： An apparatus and method for testing the flow distribution through a turbine engine fuel manifold and one or more nozzles connected to the manifold. A plurality of individual fluid measurement vessels, at least one for each of the nozzles being tested, collects test fluid pumped through the manifold and the connected nozzles. The level in each of the measurement vessels is periodically sampled during the test. The test fluid flow rate through each of the nozzles is periodically determined based on the periodically sampled levels.

摘要： The pick-up nozzle has a large flat inlet face with a gradually tapering housing extending upwardly therefrom to an angularly disposed inclined suction hose attachment. A filter screen is disposed across the inlet face with its periphery seated against a shoulder in the housing. Peripherally spaced feet extend downwardly from the housing periphery to support the screen above any surface upon which the nozzle may rest. A closure disc is spaced beneath the screen with its periphery engaging shoulders in the feet to protect the screen and restrict entrance of liquid thereto to the spaces between the several feet. A single vertical bolt suspends the screen and closure disc from the top of the housing with spacer sleeves thereon to secure the screen and disc in proper spaced position. The closure disc is dished upwardly to leave a space for the head of the bolt above the plane of the bottom of the feet. A float is pivotally attached to the top of the nozzle to maintain the latter at a preferred level in the water.

摘要： A process for the production of medrogestone, in which, in an intermediate step, the solvate 3.beta.,5.alpha.,6.beta.-trihydroxy-6.alpha.,17.alpha.-dimethylpregnan-20-one monomethanolate is obtained as a solid, stable compound by displacing the organic solvent from a solution of of 3.beta.,5.alpha.,6.beta.-trihydroxy-6.alpha.,17.alpha.-dimethylpregnan-20-one with a lower alkanol, and a Diels-Alder adduct of 6-methylene-17.alpha.-methylpregn-4-ene-3,20-dione with maleic anhydride is used as an intermediate for production of the corresponding dicarboxylic acid salt for removal of 6-methylene-17.alpha.-methylpregn-4-ene-3,20-dione contamination of the desired product. Another intermediate, 6.beta.-hydroxy-6.alpha.,17.alpha.-dimethylpregn-4-ene-3,20-dione, has been found to prevent smooth muscle proliferation and is useful in the treatment of atherosclerosis and restinosis.

摘要： Compact exhaust mixer assemblies comprising a compact mixer and a trimmable open centerbody are provided. The trimmable center body allows for adjustments of the open centerbody after manufacturing and during production testing. The trimmable open centerbody may be used to compensate for production tolerances making it possible to obtain the desired core effective area for proper engine operation. The compact mixer may be either lobed or serrated. The compact exhaust mixer assemblies have a length of about half that of conventional exhaust mixer assemblies.
