Abstract: This invention relates to a new simplified apparatus to hydrolyze proteins either in vacuo or under an atmosphere of nitrogen. More specifically, this invention consists of a sample mixture chamber attached in a seal tight manner to an inert fitting means with a tapered outlet which is connected to a two-way valve with a tapered inlet. The valve has a sealed on-off control device, and a lock connector attached to the outlet to allow an evacuating device to be connected.

Abstract: In mild cure finishing, strong catalysts are required because of the modest curing conditions employed in the process. Suitable catalysts for mild cure finishing include strong inorganic acids, strong organic acids, active inorganic complexes, salt/acid combinations, and salts that are strong Lewis acids (i.e, certain metal salts). Ammonium salts of inorganic acids, although often used in other types of treatments for producing wrinkle resistant textiles, are not satisfactory catalysts for mild cure finishing. Unexpectedly and surprisingly, it has been discovered that ammonium salts of certain, but not all, sulfonic acids can serve as effective catalysts for mild cure finishing of cellulose-containing fabrics to produce wrinkle resistance and durable press properties. Among ammonium sulfonates which provide the catalysis needed for mild cure finishing are ammonium methanesulfonate, ammonium carboxymethanesulfonate (NH.sub.4 O.sub.3 SCH.sub.2 COOH), ammonium benzenesulfonate, and ammonium p-toluenesulfonate.

Abstract: Liquid is heated to a pasteurization temperature, pumped into a holding zone wherein the liquid is divided into a plurality of slugs and the slugs are then impelled through the holding zone by mechanical action, such as piston action, applied to each individual slug.A non-exclusive, irrevocable, royalty-free license in the invention herein described, throughout the world for all purposes of the United States Government, with the power to grant sublicenses for such purposes, is hereby granted to the Government of the United States of America.

Abstract: Concentrations of undesirable heavy metals in industrial wastewater are reduced to below or very close to the most stringent aqueous discharge limits. This is accomplished by forming an insoluble metal-polyelectrolyte complex which can be easily and economically removed from the effluent.

Abstract: Knitted cotton fabrics in tubular form are impregnated to 20 to 35% wet add-on of crosslinking agent by any of several techniques including sprinkling, spraying, printing, or slop padding the solution of crosslinking agent to the outer surfaces of the fabric tube, or transferring the solution of crosslinking agent from impregnated material to the outer surfaces of the fabric tube, followed by a mechanical agitation step wherein the impregnated tubes are mechanically agitated at elevated temperatures under closed conditions, thereby eliminating agent migration toward fabric surfaces during drying of the cotton containing knitted fabrics in chemical treatments for smooth-drying properties and dimensional stabilization.

Abstract: Potatoes are converted into convenience food products, using techniques which provide advantages over customary operations. Example: Potatoes are cooked and mashed. The mash is shaped into strips which are then treated with hot air to case-harden their surfaces. The resulting intermediates may be fried directly or held in frozen or cold storage for future use. On frying, they yield products which have the taste, appearance, color, and texture of high-quality conventional French fries plus added advantages of higher solids content, lower fat content, and no tendency to get limp.

Abstract: Alkylcinnamylphenols, wherein the alkyl group contains 3-4 carbon atoms, are used as mosquito larvicides.

Abstract: Heavy metal ions are removed from water by contact with formaldehyde-modified nut waste or tree bark.

Abstract: Alpha-amylase inhibitor is prepared from whole wheat or other wheat material by blending the starting material with aqueous alkali, separating the juice therefrom, coagulating and separating a protein concentrate from the juice, and then applying acetone to the residual juice to precipitate the alpha-amylase inhibitor.

Abstract: Beef tallow is partitioned into five well defined fractions, each having its own distinctive fatty acid and glyceride composition and its own distinctive thermal characteristics, by a precise multi-step crystallization. Two of the five fractions are crystalline, one is a plastic solid and two are liquid. One of the liquid fractions accounts for 60% of the tallow and has a variety of uses in the formulation of salad oils, margarines and liquid and plastic shortenings. The composition and properties of the plastic solid fraction are very similar to those of cocoa butter and when it is mixed with cocoa butter it does not produce any significant change in thermal characteristics. In fact, an increment of one of the crystalline fractions or of one of the liquid fractions can be blended with an increment of the solid plastic fraction to make products that are compatible with cocoa butter and that have desirable thermal characteristics.

Abstract: An improved process is used to prepare encased powdered elastomers which replace slab rubber in injection molding formulations and thereby eliminates the need for milling and high shear mixing. A composition is obtained which is easily blended and is capable of being automatically fed to injection molding machines, and which contains less encasement compound than prior art powdered elastomers having similar nonagglomerating and free-flowing properties.

Abstract: Hexane and mixtures of hexane containing 2 to 25% acetic acid (v/v) were used to prepare oil and protein from glanded cottonseed by solvent extraction. As the amount of acetic acid in the solvent increased, the amounts of total lipid, phospholipid, neutral oil, and gossypol in each miscella increased, but the amount of free fatty acids did not change significantly. The solubility of the protein in 0.02N NaOH did not decrease until the amount of acetic acid in the solvent used to prepare each meal increased to a point between 4 and 10 percent. The drainage of the miscella (solvent-lipid solution) through the marc (insoluble residue) was much more rapid when the solvent was hexane-acetic acid than when it was hexane alone.

Abstract: A new apparatus for metering insect diet accurately and efficiently into individual insect rearing cells is disclosed. Insect diet is accurately metered into a set of plastic rearing cells which are preformed by a form-fill-seal machine. The insect diet is transferred from a thermally controlled reservoir through a pneumatic cylinder type metering device by means of a negative pressure on the intake and a positive pressure on the discharge. Thus very high viscosity diet materials can be utilized. The diet is discharged through a set of nozzles into individual plastic rearing cells. A ball type check valve is used on both the intake and discharge ends of the metering device, which can be incrementally calibrated by a threaded collar type mechanism. The whole apparatus is mounted to a stationary frame with a movable lower cross-head which imparts function to the metering devices. The number of metering devices can be varied and assembled in series and operated simultaneously with the number of rearing cells.

Abstract: The digestibility and protein content of straw is enhanced by treating it with dilute acid, ammoniating the acid-treated straw, and fermenting it with a yeast such as Candida utilis. The so-treated straw is useful as a feed for ruminants and other animals.

Abstract: Straw from which the hemicellulose has been removed is not digestible by ruminants. By application of the invention this material is rendered digestible. The process of the invention involves treatment of the hemicellulose-free straw with dioxane containing a small proportion of hydrochloric acid.

Abstract: Perfluoroalkyl iodide monomer and telomer ester adducts of diethyl vinylphosphonate were prepared by free radical addition. Iodine of these adducts was replaced by hydrogen, and derivatives of the reduced phosphonate adducts were prepared, which include phosphonic acids, acid chlorides, and aziridinyl phosphine oxides. The aziridinyl phosphine oxides are used to impart oil and water repellency to cellulosic textiles. The other derivatives are useful as chemical intermediates as well as potential foaming agents.
