Abstract: 25-Alkyl-3.beta.-hydroxycholest-5-en-7-ones and esters thereof adapted to lower serum cholesterol and inhibit the activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase are disclosed.

Abstract: A flexible fluid collection bag is described having an upper sampling compartment of predetermined volume and a lower collection compartment partially separated by a heat seal portion, yet remaining in fluid communication with each other. To obtain a fluid sample from the bag, the bag is inverted to fill the sampling compartment, then pivotably held at the connection of the compartments while the collection compartment is returned to its original position. The fluid remaining in the sample compartment then is discharged into a specimen collection container.

Abstract: A device for controlling the pressure in an inflatable cuff surrounding an endotracheal or tracheostomy tube is described.

Abstract: Preparation and use of platelet aggregation inhibiting and antisecretory phenyl 5Z,8Z,11Z,14Z-eicosatetraenoate and congeners are disclosed.

Abstract: Preparation and use of anticonvulsant 3,9-dihydro-3,9-dioxo-2H-indeno[2,1-c]pyridine-4-(carbonitriles/carboxamid es) are disclosed.

Abstract: A urine meter and collection assembly is described having a rigid, compartmentalized measuring container attached to a flexible wall of the collection bag. The fluid inlet and transfer ports are telescopically aligned to accept the fluid drainage tube and the flexible bag wall is utilized as a hinge during emptying of the measuring container. The telescopic arrangement provides for a compact assembly and minimizes disturbances of the patient drainage line.

Abstract: A process for upgrading a hydrocarbon fraction by contacting the hydrocarbon fraction with a dense-water-containing fluid at a temperature in the range of from about 600.degree.F. to about 900.degree.F. in the absence of externally supplied hydrogen and of pretreatment of the hydrocarbon fraction and in the presence of a sulfur-resistant catalyst.

Abstract: A process for upgrading a hydrocarbon fraction and for generating hydrogen in situ by contacting the hydrocarbon fraction with a dense-water-containing fluid at a temperature in the range of from about 600.degree. to about 900.degree.F. in the absence of externally supplied hydrogen and of pretreatment of the hydrocarbon fraction and in the presence of a catalyst system containing a sulfur- and nitrogen-resistant catalyst.

Abstract: An improved process for alkylating at least one alkylatable isoparaffin with at least one alkylating agent selected from the class consisting of an olefin and an alkyl sulfate ester in the presence of a catalyst comprising a major amount of sulfuric acid and a minor amount of hydrofluoric acid.The invention of this application is related to the inventions of the following applications filed simultaneously with this application and by the same applicant: Ser. No. 527,713 and Ser. No. 527,715.

Abstract: An improved method for the continuous production of stable aqueous ammonium polyphosphate compositions which are useful as fertilizers and fire retardants. Wet-process superphosphoric acid which is primarily in the orthophosphate form and anhydrous ammonia vapor are combined in a pipe reactor wherein the exothermic ammoniation of the acid and the conversion of a portion of the orthophosphate to polyphosphate caused by the heat liberated in the exothermic ammoniation reaction occur. A stream of the acid is introduced into the interior of a stream of ammonia vapor in the pipe reactor in order to avoid corrosion of the pipe reactor.Water is added to the reaction mixture to quench the conversion reaction and to provide the amount of water that is required in the desired final composition. The resulting stream is combined with a cooler stream of the desired final stable aqueous ammonium polyphosphate wherein the polyphosphate is cooled and the ammoniation is completed rapidly.

Abstract: A process for recovering and upgrading hydrocarbons from oil shale and tar sands by contacting the oil shale or tar sands with a dense-water-containing fluid at a temperature in the range of from about 600.degree.F. to about 900.degree.F. in the absence of supplied hydrogen and in the presence of a sulfur- and nitrogen-resistant catalyst and wherein the density of the water in said fluid is at least 0.10 gram per milliliter.
