Abstract: By combination and interaction of mechanical and aerodynamic forces, textile fibers are doffed from a processing cylinder, purged of foreign matter, subdivided and directed into a network of conveying tubes, and distributed to a multiplicity of fiber by-passing condensers wherein fibers are continuously assembled into a uniform ribbon for subsequent textile processing. The invention encompasses unique means for by-passing excess fibers for collection and reprocessing.

Abstract: A system or method by which electromagnetic wave energy in the near, intermediate, and far infrared portion of spectrum from insect sex scent attractants and host plant or animal scent attractants is converted into narrow band high intensity maserlike infrared emissions is disclosed. The system or method includes a low frequency oscillator for vibrating a silver or gold coated or aluminum low emissivity reed in a vacuum chamber with a suitable infrared window (1 to 30 .mu.m). The reed vibrator is prepared with a monomolecular layer of suitable insect sex or host attractant or surrounded by vapors of said attractants and vibrated (modulated) in an infrared source of electromagnetic energy at 1 to 30 .mu.m and at the antenna vibrating frequency of the insect. The narrow band maserlike emission and harmonies thereof are emitted through the IR window and detected by a spectrometer.

Abstract: A pollen collecting and trash removal apparatus for use on honey bee colonies in which bees entering from the field with pollen are forced to twist their bodies through a double screen grid with offset squares and lose the pollen pellets which fall through a hardware cloth into a pollen drawer. Bees leaving the hive with trash are forced to drop it, when they have to crawl through a 2 screen grid without offset squares, through a 1/2 inch hardware cloth into the trash drawer. The hinged lid permits easy removal of both grids for easy access of bees leaving or coming into the hive. The apparatus can remain on the hive throughout a year and still permit easy manipulation of frames in the hive. Pollen and trash drawers are removed from the side of the hive without obstruction to the normal flight of the bees. The use of hardware cloth or wire screen permits the maximum amount of ventilation.

Abstract: Creasability properties are imparted to cotton cellulosic and other hydroxy-containing polymeric fabrics and fibers by reacting them with N-methylol derivatives in the presence of phosphorylating agents. The resulting fabrics are both heat creasable and crease resistant.

Abstract: Phosphonated N,N-disubstituted fatty acid morpholine derivatives were prepared by the free radical addition of dialkyl phosphites to terminal and nonterminal double bonds of N,N-disubstituted fatty acid morpholine derivatives. The free radical additions of the dialkyl phosphites to the unsaturated fatty acid morpholine derivatives were initiated by irradiation with gamma radiation from cobalt-60. These new compounds exhibit antimicrobial activity.

Abstract: A fibrous material consisting of cellulosic or other natural fiber, synthetic fibers, or blends of various fibers is treated with an aqueous reagent system having a pH above 3.6 that is comprised of one or more carboxyl-containing vinyl monomers, a free-radical initiator, and a suitable base to adjust the pH. Comonomers and water-soluble di- or polyfunctional vinyl monomers may be included. Polymerization is conducted at elevated temperature in an atmosphere in which air may be diluted by steam and/or steam-nitrogen. The polymer is durably fixed to the fibrous substrate and contributes various special performance properties thereto.

Abstract: Prearranged ribbons of fiber leaving the front drafting roll are superimposed into layers by a composite sliver forming assembly before entering a trumpet. The composite sliver forming assembly consists of tubular guides extending at an angle from the front drafting roller to the trumpet entrance. The tubes are designed with a flat bottom to support the sliver, allowing for overlapping at the tube exit, and to achieve an exact ribbon exit 90.degree. downward into the trumpet entrance where the layered ribbons are combined into a composite sliver.

Abstract: An apparatus for holding fabric samples during tensile testing under constant temperature and wet conditions comprising a pair of clamping jaws between which is held a fabric sample, secured by a standard metal eyelet which is inserted through a hole provided in said jaws and sample for said eyelet.

Abstract: Grafted cotton-poly(ethyl acrylate) copolymer and grafted mercerized cotton-poly(ethyl acrylate) copolymer have been prepared by a process which equates their reactivity. The process discloses the reaction of irradiated cotton and irradiated mercerized cotton with certain solutions of ethyl acrylate in either water, methanol, or mixtures thereof to yield the copolymer derivatives which have responded equally and do respond equally to further treatments.

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: Methylol phosphines, methylol phosphines in combination with amine or amido compounds or water soluble adducts of these methylol phosphines and amides or amines when mixed and reacted with mono, di or polyisocyanates wherein the isocyanate groups are attached to carbon atoms are particularly valuable for the preparation of thermosetting flame resistant polymers. The polymers which are produced are crosslinked phosphorus and nitrogen containing polymers in which the reoccurring structure units each contain a phosphorus atom, that is a component of a radical of the group tris(methylene)-phosphine (--CH.sub.2).sub.3 P and is linkd to at least one isocyanate radical by connecting urethane structure.The polymer forming solutions are also valuable for the preparation of flame-, glow-, wrinkle- and shrink-resistant textiles by impregnating fabrics with these solutions and causing reaction and polymer formation by application of heat.

Abstract: This invention relates to fabric treatments by which cotton and cellulosic blended fabrics can be provided with wrinkle resistance (smooth dry performance) and color at the same time. In particular, it provides a means by which cellulosic fabrics can be dyed with basic dyestuffs. In addition to a conventional means by which the entire fabric can be dyed with a basic dye, variations are achieved in which one side of the fabric is dyed one color and the other side of the fabric is dyed a second color. The color on the reverse side can be provided by means of either basic dyes or regular cotton dyes. The technique has also been extended for the printing of fabrics.

Abstract: Soluble adduct polymers were allowed to react with nitrogenous compounds such as urea, trimethylolmelamine, and ammonia 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: This invention relates to the preparation and use of durable press fabrics with strong acid grafts. The preparation is accomplished by the incorporation of a reactive hydroxyalkyl sulfonic or phosphinic acid in a crosslinking finishing system. As a consequence of this, durable press fabrics are produced with sulfonic or phosphinic acid grafts. Because of these strong acid grafts, these fabrics show improved moisture regain properties, can be dyed with basic dyes, can be whitened with basic optical brighteners and have ion exchange properties for metallic cations.

The cellulose-dyeing dyestuff of the invention is prepared by reacting a conventional cellulose-dyeing dyestuff having a chromophoric radical containing the aforesaid vinyl sulfone groups (e.g., Cl Reactive Black 5 and Cl Reactive Violet 4) with a hydroxy carbamate, and methylolating the resulting product.

Abstract: A solvent system composed of ethanol-acetonitrile-water dissolved certain membrane proteins of biological origin. The solvent system was optically transparent to ultraviolet radiation from 200 to 400 nanometers (nm). This transparency permitted ascertainment of spectral characteristics of membrane proteins at these wavelengths.
