Abstract: An automatic polishing system for polishing semiconductor material is described. A robot and Bernoulli pickup are used to retrieve polished wafers from an underwater unload station which is located on a wafer polisher. The polished wafer is then deposited into a cassette which is located underwater.

Abstract: A fuel atomizing throttle body is formed to receive a centrally located fuel injector near the inlet to the throttle body induction passage, the throttle body having an axially moveable throttling sleeve in the induction passage that cooperates with a fuel atomizer adjacent the injector for variably metering the primary flow of air into the engine while simultaneously increasing the velocity of the air to impact the metered fuel essentially at right angles to the fuel to atomize the same prior to entry of the mixture into the engine, the fuel atomizer having swirl passages further mixing the fuel with air upon discharge from the injector and providing a secondary minimum air flow volume to sustain engine operation during idle speed conditions when the primary path is closed.

Abstract: Aminosubstituted tetrahydrobenzindoles having antihypertensive activity are disclosed.

Abstract: Hexahydronaphth[1,2-b]-1,4-oxazines have dopaminergic activity and display .alpha..sub.2 -adrenergic receptor antagonism. They are useful in the treatment of parkinsonism, depression and hypertension. An important method of preparation is by ring closure of the appropriate 2-chloroacetamidotetrahydronaphthalen-1-ol and reduction of the resulting cyclic amide carbonyl group.

Abstract: 4-Substituted-2,3,4,4a,5,6,7,11b-octahydrobenzo[6,7]cyclohept[1,2-b]-1,4-ox azines are prepared from the corresponding 6-(substituted amino)-6,7,8,9-tetrahydro-5H-benzocycloheptene-5-ol. The trans-4-substituted-2,3,4,4a,5,6,7,11b-octahydrobenzo[6,7]cyclohept[1,2-b] -1,4-oxazines have .alpha.-adrenergic agonist and tetrabenazine antagonist activity.

Abstract: Aminosubstituted tetrahydrobenzindoles having antihypertensive activity are disclosed.

Abstract: Indolobenzoxazines, their preparation and pharmaceutical use are disclosed.

Abstract: This invention relates to 8-aza-9-ozo(and dioxo)-thia-11,12-secoprostaglandins and processes for their manufacture. These compounds have prostaglandin-like biological activity and are particularly useful as renal vasodilators, for the prevention of thrombus formation, to induce growth hormone release, and as regulators of the immune response.

Abstract: Novel 8-aza-9-dioxothiaprostanoic acid compounds, their salts, and derivatives, are prepared from ethyl 7-(3-hydroxymethyl-2-isothiazolidinyl)-5-heptynoate S,S-dioxide by first hydrogenating the triple bond over a Lindlar catalyst, followed by mild oxidation, to produce the corresponding 3-formyl compound, which is condensed with the ylide prepared from dimethyl-(2-oxoheptyl)phosphonate to produce the .alpha.,.beta.-unsaturated ketone, followed by reduction to the corresponding carbinol, and ester hydrolysis. The compounds are useful especially for the treatment of patients with poorly functioning kidneys, as hypotensives, or as platelet aggregation inhibitors.

Abstract: The invention is concerned with novel 16-aryloxy-, 16-alkoxy-, 16-arylthio- and 16-alkylthio-8-aza-9-dioxothia-11,12-seco-prostaglandins and processes for their preparation. These novel compounds are useful as pharmaceuticals since they can be used in animals for estrus synchronization and treatment of infertility due to persistence of luteal function.
