Apparatus for the analysis of samples such as blood or urine includes a reaction cell for reacting the sample with a chemical reagent at a predetermined temperature. A heat exchanger is provided on the reaction cell for establishing the temperature of the cell. Reagent is pumped into the cell through a conduit, and a portion of the conduit is wound around the reaction cell in contact with the heat...

A resin impregnated fibrous web is comprised of a needled fibrous batt and a polymeric resin distributed throughout the batt. The density of the impregnated web is uniform throughout with the bulk density of the web being less than the actual density of the web whereby the web is porous. The impregnated web has filaments which are both coated and uncoated with the polymeric resin. A method of form...

A drilling system comprises a drill string (1) incorporating inbuilt tubular conductors (25), a mud supply passage, and passages for protective or other fluids. The drill string can be advanced by selectively actuable pistons (51,60) exposed to drilling mud flow, by electrically driven traction units (71,74) engaging the drill hole wall or by a linear electric motor element (82) co-operating with ...

An earth-contact plug of waterproof design must have a screw ring in accordance with DIN 49443, which screw ring connects the plug to the plug socket by means of a bayonet closure. The object of the invention is to create a design which is as space-saving as possible. To this end a link consisting of insulating material is inserted between the front part (1) and the rear part (2) of a transversely...

A lightweight, unitary plastic pallet adapted for handling heavy powder loads. The pallet has a substantially rigid lower deck, a flexible, reinforced and continuous upper deck adapted to deflect against the lower deck under load, and a plurality of integral legs permitting forklift transport of the pallet.

1522182 Calcium phosphate ceramics STERLING DRUG Inc 22 July 1975 [2 Aug 1974 7 July 1975] 30706/75 Heading C1A A polycrystalline, sintered ceramic for use as a bone or tooth substitute is made by reacting calcium ion with phosphate ions in aqueous medium at pH of 10-12 to produce a gelatinous calcium phosphate precipitate having a Ca:P molar ratio of 1À44-1À72, separating the precipitate from the...

A process for treating a mercaptan-containing sour petroleum distillate is disclosed. The process comprises contacting said distillate with a supported mercaptan oxidation catalyst at oxidation conditions in the presence of a substituted ammonium halide commingled with an alkaline reagent.

The present invention relates to total and partial esters of alginic acid with alcohols of the aliphatic, araliphatic, cycloaliphatic, aliphatic-cycloaliphatic and heterocyclic radicals, and salts of said partial esters with inorganic and organic bases. The said partial ester are not a partial ester of bivalent aliphatic alcohols. These compounds are intended to be used in pharmaceutical. applicat...

A dispenser for capsules or the like utilizes a turnstile member (44) rotatable in only a single direction to transport the capsules from a reservoir (14) to an exit port (40). Fingers (50) on the turnstile arms interleave with corresponding fingers (52) on the dispenser housing (38) to prevent a capsule from being rotated beyond the exit port and back into the housing. A propeller member (20) in ...

Novel compounds of the formula (I) in which R1 is a hydrogen or a silyl or acyl group, R2 is methyl, ethyl, isopropyl or sec.-butyl and R is hydrogen, unsubstituted or substituted, linear or branched-chain C1-C18-alkyl groups, unsubstituted or substituted cycloaliphatic groups having 3 to 10 carbon atoms, unsubstituted or substituted C2-C6-alkenyl groups, unsubstituted or substituted ...

The invention provides alkynylamino-nucleotides and their labeled derivatives which are useful, for example, as chain terminating substrates for DNA sequencing, along with several key intermediates and processes for their preparation.

A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spec...
