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.

Abstract: An edible high-protein flour is produced by an improved process. Cottonseed meats are dried, and then comminuted in a wide chamber mill having certain specifications which prevent rupturing the pigment glands of the cottonseed. This improvement is correlated with liquid cyclone separation followed by solids recovery steps, thus comprising an improved process which consistently yields an edible cottonseed protein concentrate.

Abstract: A new apparatus and method for feeding cotton continuously, uniformally, and at a constant rate to individual gin stands in a battery of gin stands is disclosed. The full flow feeder comprises a rectangular chamber with an upper and a lower section. Valves which form part of the chamber sides in the open position close to form two sections when in the closed position, causing the device to operate as a single chamber in the open position and a dual chamber in the closed position. On-off control switches located in the upper and lower sections operate to balance the flow of seedcotton by signaling a system of hydraulic cylinders to open and close the valves.

Abstract: Economical foams have been prepared from selected formulations containing whey solids, animal glue, surfactants, viscosity-builders, and activated charcoal. These foams are lightweight and act as carriers for the charcoal. Easy handling and dispersibility of the activated charcoal was accomplished by a combination of surfactants, either one being used as a wetting agent to control the activated charcoal and the other added to the remainder of the formulation. When applied broadcast on the soil, these foams are useful in removing from the soil residual toxic herbicides and pesticides which can cause significant damage to a sensitive succeeding crop.

Abstract: This invention relates to a process for producing crossdyed cotton fabrics. For this purpose, by means of a chemical technique, procedures which permit the dyeing of selective yarns in a fabric have been developed.

Abstract: This invention relates to an apparatus for stretching a textile material such that the magnitude of the strain at all points is equal in all directions in the plane of the specimen. The embodiment disclosed is an expandable circular pin frame. The pins mounted in puley are uniformly displaced radially outward and impart uniform radial strain without the edge effects associated with similar apparatus employing nonexpanding fastening mechanisms.

Abstract: Novel quaternary arylaminoalkyl phosphonium salts having the formula [(ArNHCHR).sub.4 P].sup.+X.sup.-, where R is a radical selected from the group consisting of hydrogen, alkyl and aryl, Ar is aryl, and X is halogen, are prepared by the reaction of primary aromatic amines with quaternary hydroxyalkyl phosphonium salts having the formula [(HOCHR).sub.4 P].sup.+X.sup.-, where R and X are similarly defined. The compounds of this invention are useful as flame retardant for cotton, plasticizers, lubricant additives, and surface-active agents.

Abstract: A synthetically prepared boll weevil attractant has been formulated so as to include crude cottonseed oil. This formulation, in the form of a gelled emulsion, has been used to trap and destroy boll weevils for periods up to 2 weeks. The new formulation releases the active ingredients at a more favorable rate and is effective for longer periods than previously developed ones.

Abstract: Soluble adduct polymers were allowed to react with phenol, alkyl substituted phenols or halogen substituted phenols which contain one or more hydrogens ortho or para to the phenolic hydroxyl group to (a) prepare flame resistant polymers and (b) prepare flame-, glow-, wrinkle- and shrink-resistant woven and knit textiles which contain 25% or more cellulosic fibers.

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.
