Abstract: Abstract of the Disclosure A method and reagent for reducing errors in any assay systems wherein nicotinamide adenine dinucleotide (NAD) is reduced, the reduced form of NAD being a quanti-tative measure of the sample constituent being measured, and being subject to reaction with any pyruvate and lactic dehydrogenase (LDH) which may be present.  Specifically, the method comprises conducting the assay in the presence of oxalic or oxamic acids or their salts, which form an inactive complex with LDH, thereby eliminating interferences due to the presence of any LDH.  Glucose and creatine phosphokinase assays are examples of assays wherein the reduced form of NAD is measured, and consequently, the presence of either pyruvate or lactate in the sample will cause errors in the assay.  The method can also be employed in assay systems wherein the reduced form of NAD (NADH) is oxidized to NAD.  In such systems, the disappearance of NADH is a measure of the constituent being measured so that any interference can cause errors in the assay.  An example of such a system is the measurement of plasma ammonia using glutamic dehydrogenase.

Abstract: This invention relates to an improved injection molding filter assembly to be located in a passage between the molding machine and the mold to remove contaminants such as wood, paper, or metal from the molten plastic material or melt. The filter assembly has an upstream circular plate located adjacent a downstream circular plate and the plates are secured against relative rotation by pins passing therethrough.  The upstream and downstream plates each have a number of circular openings therethrough arranged in concentric circles with each of the openings in each plate partially overlapping at least two openings in the other plate, whereby a plurality of restricted eye-shaped openings are provided through the filter assembly in the abutment plane between the two plates.  The filter assembly is securely retained in mating seats in the back plate and the adjoining manifold spreader plate or nozzle.  The contact plane between the back plate and the manifold spreader plate extends approximately midway the height of the downstream plate of the filter assembly, whereby the filter assembly also acts as a locator to prevent relative lateral movement between the back plate and the manifold spreader plate. The filter assembly according to the invention is durable, relatively inexpensive to manufacture, has an unexpectedly low pressure drop across it and exerts a considerable homogenizing or mixing effect upon the melt flowing through it.

Abstract: ABSTRACT OF THE DISCLOSURE                    Condensation of the addition product of glyoxylic acid and amides with hydroxyaryl compounds is effected by a first step, wherein the reaction is carried out hot, at a temperature below 60°C, of an aliphatic amide having at the most 4 carbon atoms selected from the group of acetamide, chloracetamide, propionamide, acrylamide and butyramide, on an aqueous solution of glyoxylic acid.  Then in a second step, after the addition of acetic acid and ga-seous hydrochloric acid, condensation is effected at a tempe-rature below 35°C of the carboxamidoglycolic acid with an excess reaching 500% of hydroxyaryl compound selected from the group comprising phenyl and its alkyl derivatives, their halogen derivatives, polyphenols and their ethers and beta-naphthol.  After the condensation of said second step, the volatile products are removed by vacuum sidtillation.  When the hydroxyaryl compound is phenol, the crude product result-ing from this distillation is taken up in nitromethane or water, which are a non-solvent of the N-acyl derivative of parahydroxyphenylglycine but a solvent of the corresponding ortho derivative; the proportion of the para derivative in the resulting compound is then of the order of 100%.

Abstract: Abstract of the Disclosure A respiratory exerciser particularly for encouraging deeper inhalation by post-surgical patients.  The exerciser includes a transparent cylinder that is adapted to be supported in a vertical position.  A lightweight ball is positioned in the cylinder which is provided with closure members at its upper and lower ends.          The closure member for the upper end of the cylinder has a pair of apertures therethrough, and an open-ended tube is slidably mounted in one of the apertures so that it projects down into the cylinder, A flexible inhalation tube is connected to the other closure member aperture and by inhaling air through this tube the patient can cause the ball to rise in the vertical cylinder.  Moving the open-ended tube up or down in its aperture varies the distance that it projects into the cylinder, and this in turn varies the degree of difficulty in raising the ball.  Easily visible grad-uations on the cylinder enable the patient to see how high he is raising the ball and thus give a measurement of his progress.

Abstract: ABSTRACT           A protective system is provided for water-jet propulsion systems in which water entering through an intake port is discharged in a jet by a pump.  Unloading and overspeed of the pump prime mover may occur if the intake comes out of the water and this is prevented by a system which senses the water pressure in the pump inlet and responds to the pressure and the rate of change of pressure to prevent overspeed of the prime mover by setting it to idling speed.  When the pressure and rate of change indicate that the intake is again submerged, the prime mover is reset to normal operating control.

Abstract: Abstract Elongate copper bodies, such as rods and wires, of electric conductor grade are made by electrodepositing copper as brittle cathodes which are then broken into fragments and fed as such to a continuously-acting friction-effected extrusion ma-chine (such as Conform or Linex) which consolidates, bonds and extrudes them.  The fragments have a specific surface area of about 25 - 1000 mm2/g, and they are not subjected to any high-temperature purification or grain growth step prior to extrusion, though moderate pre-heating is allowed.   Avoidance of high-temp-erature processing, such as conventional casting and hot-rolling, saves much energy and in addition copper of higher quality is produced.

Abstract: WATER-SOLUBLE DYEING COMPOSITIONS FOR THE PREPARATION OF ANIONIC FIBER-REACTIVE AZO DYESTUFFS AND THEIR USE FOR DYE-ING AND PRINTING Abstract of the disclosure:    Novel, water-soluble dyeing compositions for the prepara-tion of anionic dyestuffs had been found which do not contain the azo dyestuffs themselves but their starting components.          These dyeing components contain, or consist of, about stoichio-metrical amounts of a diazotizable aromatic amine, of a coupl-ing component and of an alkali metal nitrite, at least one of the diazo or coupling components or both contain a water- solu-bilizing, free acid group.  The dyeing compositions may contain additionally buffer substances and dyeing auxiliaries as usual in the art.  The dyeing compositions are capable of forming very easily, if mixed with or stirred into water, aqueous solu-tions of azo dyestuffs, and these solutions can already be used after a residence of 5 to 30 minutes for the preparation of dyeing baths, dyeing liquors and printing pastes for the dye-ing of fiber materials made of cellulose or derivatives there-of or of natural or synthetic polyamide fibers.  In accordance with that, it had also been found a process for the  coloring of fibers of said materials, wherein the composition is dis-solved in water, and the azo dyestuff solution obtained is modified by optionally adding buffer substances and usual dyeing auxiliaries to prepare a  usual dyeing liquor or printing paste which is then applied on said fiber material, and the dyestuff is fixed by methods usual in the art.
