Both of these scintillators have been found to provide a balance of good stopping power, high light yield and short decay constant that is superior to other known scintillator materials. The radiation detectors disclosed are favorably suited for use in general purpose detection and in medical uses.

Abstract: A method and device for generating pulsed jets which will form plumes comprising eddie structures, which will entrain a fuel/air mixture from the head space of an internal combustion engine, and mixing this fuel/air mixture with a pre-ignited fuel/air mixture of the plumes thereby causing combustion of the reactants to occur within the interior of the eddie structures.

Abstract: A system for controlling combustion in internal combustion engines of both the Diesel or Otto type, which relies on establishing fluid dynamic conditions and structures wherein fuel and air are entrained, mixed and caused to be ignited in the interior of a multiplicity of eddies, and where these structures are caused to sequentially fill the headspace of the cylinders.

Abstract: An especially efficient and durable electrolytic cell is provided by utilizing a combined cathode and diaphragm unit wherein the cathode is made by spray coating a ferrous metal substrate with a powder metal having lower hydrogen overvoltage than said substrate to form a protected cathode surface having a larger surface area than the substrate, and vacuum depositing fluorinated hydrocarbon polymer fibers onto the spray coated surface of the cathode to form a fibrous diaphragm securely adhered thereto. Preferably, the cathode surface is made with nickel and the fluorinated hydrocarbon polymer is selected from the group consisting of homopolymers of chlorotrifluoroethylene and copolymers of chlorotrifluoroethylene and at least one compatible monomer with units of chlorotrifluoroethylene accounting for at least 80 percent of the monomeric units of said copolymer.

Abstract: An electrolysis cell assembly of the filter press type having plastic frames and a membrane wherein the membrane is formed to fit between adjacent frames with one or more recesses provided on one or both of the adjacent frames together with sealing gasket means which are formed for effectively controlling electrode spacing and for retaining the membrane in position without membrane damage. The construction not only provides proper sealing and protection of the membrane during use, but also allows for the membrane to be removed, reactivated, and reused.

Abstract: Process for the manufacture of polyurethane adhesives with uniform molecular weights which are accurately adjustable and reproducible consisting of diisocyanates, polyols, chain extenders if required, catalysts and additives, all of which are soluble in polar, organic solvents which are inert with respect to isocyanate groups. The polyaddition process is carried out by using an excess of diisocyanate, the reaction is terminated upon reaching the desired molecular weight, and the still existing excess isocyanate groups are allowed to react with alcohols, ammonia and/or amines. The process is characterized in that the polyurethanepolyaddition products are crushed into particles of 1-15 mm and that they are treated with possibly substituted primary, aliphatic mono- to trivalent alcohols, ammonia and/or aliphatic, cycloaliphatic or aromatic mono- or diamines in the liquid or vapor phase in the absence of organic solvents.

Abstract: In a process for making chlorine electrolytically in which a build-up of nitrogen trichloride occurs in the bottoms of cooling apparatus, a method and apparatus is provided wherein the nitrogen trichloride is dissolved in an organic solvent such as carbon tetrachloride, the chlorine removed, and the solution treated to destroy the otherwise hazardous nitrogen trichloride. The solvent is then separated and recycled to avoid environmentally undesirable waste products.

Abstract: Phosphated ferrous metal surfaces are treated with a rinse containing citric acid and sodium nitrite to enhance corrosion protection. This rinse has the advantages of providing an effluent which is not objectionable from an environmental viewpoint and does not stain the treated surfaces.

Abstract: A process for recovering a catalyst adsorbent from a polyol-adsorbent residue by treatment of the polyol-adsorbent residue with organic solvents. This adsorbent can then be recycled for use in the further removal of alkaline catalysts from polyether polyols.

Abstract: A thickened acid cleaner concentrate composition comprising an inorganic acid, e.g., hydrochloric, an organic acid, e.g., oxalic, a nonionic surfactant, an anionic surfactant, a flocculating agent such as iron or aluminum ion and water is used to clean vehicles such as railroad equipment. The waste water is then treated by increasing its pH to cause flocculation and separation to remove suspended solids and entrained BOD prior to discharge or re-use within the plant. The flocculating agent in the composition provides a proportional pretreatment of the waste to facilitate the final treatment and separation of waste in the used composition.

Abstract: New polyether polyols of predetermined structure are prepared by reacting polyether bis alcoholates with selected bis epoxides. Specifically, a polyoxyalkylene glycol is converted to the bis alcoholate, and then the bis alcoholate is reacted with an equivalent amount of a glycol bis glycidyl ether, with the reactants being mixed together all at once. The polyether polyalcoholate thus obtained is converted to a high molecular weight polyether polyol by acid neutralization or ion exchange.

Abstract: A method of compression testing resilient articles comprising the steps of cutting a sample to desired predetermined dimensions, placing the sample in a preflexing machine to provide preflexing at test specifications, and testing the preflexed sample in a sophisticated compression testing machine. The preflexing machine uses a fluid operated cylinder to move a pressure foot member into and out of the sample to compress same the desired number of times, at the desired rate of deflection and desired number of compressions at a fixed total proportion of compression. The machine is automated through a stepping switch driven in steps by a pulse operated drive mechanism which receives pulses from limit switches associated with the movement of the pressure foot. The stepping switch controls the cylinder through solenoids operating a switching valve means to alternately supply fluid pressure on each side of the piston in the cylinder.
