Abstract: There is provided a light stability chamber for determining the stability to light of samples, for example, of pharmaceuticals in order to determine the shelf life of the samples by subjecting the samples to light from all angles.

Abstract: A process is disclosed for the production of an anticoagulant composition which allows for the accurate analysis of blood electrolyte concentrations. Also disclosed is the anticoagulant composition produced in accordance with the disclosed method and an apparatus containing the composition useful in the selection and sampling of blood.

Abstract: The present invention is directed to a process for reducing the adverse taste and malodor associated with the H.sub.2 -antagonist nizatidine. The process involves forming an aqueous solution of the H.sub.2 -antagonist, and subjecting said solution to elevated temperatures sufficient for a period sufficient to cause a reduction in the adverse taste and/or malodor of the H.sub.2 -antagonist.

Abstract: The present invention is directed to liquid medicinal suspension compositions for the administration of doses of active pharmaceutical agents such as H.sub.2 -antagonists. H.sub.2 -antagonists are known for their adverse taste and/or malodor and the claimed suspension functions to mask the adverse taste and odor of such active ingredients. Also disclosed are liquid medicinal compositions comprising the claimed suspension composition and the H.sub.2 -antagonist active ingredients.

Abstract: A vapor phase process for the synthesis of alkoxysilanes of the general formula HSi(OR'").sub.x (R").sub.3-x which comprises reacting(a) a silane of the general formulaHSi(NRR').sub.x (R").sub.3-xwherein R, R' and R" are individually hydrogen or an aryl or alkyl group optionally containing unsaturation, each having from one to eight carbon atoms inclusive, and where R' may also be an alkoxy or carbamato group and where x has a value of from one to three; with(b) an alcohol of the general formulaR'"OHwherein R'" is an aryl group, or an alkyl group optionally containing unsaturation, each having from one to twenty carbon atoms inclusive and optionally substituted said reaction taking place in the presence of(c) a catalystin which both the silane and the alcohol are present in gaseous form in a stoichiometric ratio of 0.4 to 1.05 moles of alcohol per mole of silicon-nitrogen bonds and where said catalyst is present in an amount from 0.01 to 10 mole percent of the silicon-nitrogen bonds.

Abstract: Combustion-resistant heat-curable compositions comprising:(a) an aminoorganopolysiloxane polymer containing an average of at least one hydrogen atom bonded to nitrogen in at least two of the silicon-bonded primary or secondary aminoorgano groups;(b) the reaction product of an organic polyisocyanate and a compound containing at least one alcoholic, phenolic, silanic or oximyl hydroxyl group or thiol group as a curing agent; and(c) a combustion inhibiting amount of an additive selected from the group consisting of:(i) a chromium compound;(ii) an iridium compound;(iii) a molybdenum compound;(iv) a rhodium compound;(v) a mixture of (I) platinum or a platinum compound and (II) a compound selected from the group consisting of a barium compound, a bismuth compound, a boron compound, a calcium compound, a chromium compound, a cobalt compound, a gallium compound, an iridium compound, a magnesium compound, a manganese compound, a molybdenum compound, a nickel compound, a palladium compound, a rhodium compound, a thoriu

Abstract: Novel room temperature vulcanizable polydiorganosiloxane compositions comprising an .alpha.,.omega.-dihydroxypolydiorganosiloxane and a poly-(alkoxysilylalkyl)amine. These compositions are neutral cure, exhibit excellent shelf life stability, possess a practically controllable cure rate and upon curing produce elastomers which have good adhesion to building materials and which possess good weatherability.

Abstract: A method is disclosed for the recovery of biological material from an aqueous solution comprising contacting a water-insoluble, particulate binder with a solution containing biological material to produce a water insoluble biological material/binder composition which may then be recovered. The aqueous solutions may then be recycled.

Abstract: Novel 3-ring tetraglycidates having the formula ##STR1## wherein X=O, S, ##STR2## --CH.sub.2 --, C.dbd.O; Y=halogen, C.sub.1 -C.sub.4 alkyl; and p0 n=0 to 4, are disclosedEpoxy resin systems exhibiting good tensile properties and moisture sensitivity can be made by copolymerizing the tetraglycidates with a polyamine curing agent. Prepregs can be made by combining the epoxy resin systems with a fiber reinforcement. The epoxy resin system may include a co-epoxide.

Abstract: Articles manufactured by bonding two or more shaped fiber reinforced polymeric substrates together can be made by an improved process comprising:applying a self-crosslinking acrylic polymer latex primer to the bonding surface of each of said substrates and allowing said primer to dry,applying an epoxy adhesive, in an amount sufficient to effect adhesion, to the bonding surfaces thus primed, andcontacting the bonding surfaces thus primed and epoxied with one another, under conditions sufficient to cure the epoxy, to achieve bonding.
