Abstract: A process is provided for dyeing articles of unmodified polyolefin polymer with an aqueous dispersion of a fatty-acid-soluble, solvent dye, a fatty acid and an amine. After application of the dispersion to the article, the amine is volatilized from the applied dispersion. The process is particularly useful in providing novel, dyed, nonwoven fabrics made from polyethylene film fibrils.

Abstract: A process is provided for the removal from paper pulp of impurities, the pulp being contained in a pulping machine. Some of the pulp is periodically transferred into an enclosed chamber annexed to the pulping machine, the chamber having a volume which is small compared to the volume of the pulping machine. The pulp in the chamber is stirred and separated by a rotor, and fibre suspension is returned to the pulping machine, dilution water being introduced into this chamber. The chamber is emptied and impurities thereafter discharged.

Abstract: Dispersants which improve the gloss of acrylic paints are prepared by reacting the isocyanate groups of monomeric polyisocyanates or isocyanate acrylate polymers with (1) fatty amines, (2) lower alkylamines or alkanolamines and (3), optionally, aminosilanes. A formula for the dispersants may be written as: ##STR1## isocyanate residue, A is fatty amine residue with a=20-80, B is lower alkylamine or alkanolamine residue with b=80-20, and C is aminosilane residue with c=0-40, the sum of a+b+c=100, the (mole) percentage of isocyanate groups replaced.

Abstract: Aqueous mixtures of water-soluble 7S and 11S proteins are effectively fractionated and isolated by precipitating the 11S protein at a pH 5.8-6.3 in the presence of carefully controlled concentrations of water-soluble salts and sulfurous ions. The enriched 7S whey may then be adjusted to a pH 5.3-5.8 to precipitate substantially all of the remaining water-soluble 11S protein from the whey and an enriched 7S fraction may then be recovered from the whey. The fractionation is capable of producing either 11S or 7S isolates which respectively contain less than 5% 7S or 11S protein impurities.

Abstract: A method for removing aluminum from PET bottle scrap flakes comprises:(1) mixing the scrap flakes with a solution containing a chemical that reacts with aluminum such that the aluminum in the scrap will completely dissolve into the solution; then(2) decanting off the solution with the aluminum dissolved in it, so as to leave behind PET flake; and finally(3) washing the PET flake.

Abstract: A coating composition of polymers of a vinyl oxazoline drying oil ester which esters are made by a process which reacts drying oil fatty acids with tris (hydroxy methyl) amino methane to form an intermediate which is further reacted at about 175.degree.-190.degree. C. with a formaldehyde/alcohol solution to form the vinyl oxazoline drying oil ester; the improvement used with this process is the use of at least 3 moles of formaldehyde to one mole of intermediate and about 1-5% by weight, based on the weight of the intermediate, of methanol and adding after the reaction with formaldehyde about 5-25% by weight, based on the weight of the ester solution, of an alcohol, a ketone or a mixture of an alcohol and a ketone; the coating composition are aqueous and contain sufficient ammonia or amine to provide a pH of about 7.5-9.5.

Abstract: Polymers of vinyl oxazoline drying oil ester which esters are made by a process which reacts drying oil fatty acids with tris(hydroxy methyl) amino methane to form an intermediate which intermediate is further reacted at about 175.degree.-195.degree.

Abstract: A signal-processing system, e.g. for a telephone exchange, comprises n modular processing units each including a pair of identical microprocessors operating in parallel on binary signals arriving over an internal bus, only one microprocessor of each pair being enabled to transmit outgoing messages to that bus while the other operates as a dummy. The two microprocessors are interlinked by a correlating connection enabling verification of their correct operation in response to microinstructions read out from respective microprogram memories thereof under the control of a common clock. A momentary divergence, resulting from a relative lag in the response of one microprocessor to an asynchronously arriving signal bit, results in a delay of the microprogram by one clock cycle to permit resynchronization; longer-lasting disparities lead to a deactivation of the microprocessor pair and to the emission of an alarm signal.

Abstract: Large-scale apparatus and process for chromatographic separation of fructose/dextrose sugar solutions employing large diameter beds of a strongly cationic salt of an ion exchange resin. The cationic ion exchange resin is densely and uniformly packed in a separation column by means of a resin loading method which includes washing the resin with a salt selected from the group of calcium, barium, strontium or silver salts of the resin. The shrunken resin is then placed in the column to completely fill the column. After sealing the column, excess salt is washed away to thereby expand the resin inside the confined separation column chamber.The uniformly dense packing of the resin in the separation column chamber eliminates the need for mechanical baffles which were formerly required to insure regular and uniform flow throughout the entire cross sectional area of the separation columns.
