Abstract: A system for enhancing the freezing and freeze-thaw stability of hair conditioning compositions has been developed which comprises incorporating therein a combination of low HLB (from about 2.0 to about 9.0) and high (from about 10.0 to about 19.0) HLB ethoxylated branched-chain fatty alcohol ethers and/or esters as freeze-thaw stabilizers while maintaining the pH of said emulsion in a range of about 2.0 to about 5.5.

Abstract: A in-line extrusion die is disclosed including a cylindrical mandrel and a die bushing surrounding the mandrel and forming therebetween a passageway leading to an extrusion orifice. The mandrel is mounted to one side of a spider plate and a tailcone is attached to the other side thereof. A die body containing a melt chamber surrounds the tailcone and forms a conical passageway therebetween. A thermocouple is mounted at the apex end of the tailcone for measuring the temperature of the melt as the melt flows from the melt chamber and through the conical passageway. The spider plate contains a plurality of openings which communicate with both passageways and allow the melt to pass through the plate and thence to the extrusion orifice.

Abstract: The invention is a process for recrystallizing sugar. The invention involves admixing a first quantity of a powdered sugar and a second quantity of an adjuvant, such as an invert sugar, to provide a sugar blend. The sugar blend has up to about 3 percent moisture. The invention then involves mixing the sugar blend with a high shear extruding means at a temperature between about 220.degree. F. and about 300.degree. F. with a residence time in the extruding means of between about 0.5 second and about 12 seconds. The invention includes the product of a combined phase recrystallized sugar.

Abstract: An extrusion die apparatus for extruding a multiple layer tubular product including a plurality of annular die elements mounted co-axially one behind the other on a mandrel forming annular thickness control passages between the die elements and the mandrel. The die elements have inner and outer conical surfaces inclined rearwardly with respect to the longitudinal axis of the mandrel. The die elements are nested together with the outer conical surfaces of one die element facing the inner conical surfaces of an adjacent die element. The inner and outer conical surfaces form conical passages which communicate with the annular thickness control passages and a plurality of helical grooves are provided on the outer conical surface of each die element. A binary divider system is provided for distributing a molten thermoplastic material from an inlet to a plurality of outlets communicating with said grooves on each die element.

Abstract: The invention is a composite food subsystem that provides a sweet or savory-flavored thermostable filling having an ultra-low water activity. The thermostable filling is, also, thixotropic or "shear thinning". The filling includes an edible hydrophilic liquid phase. A stabilizing network of ultrahigh surface area cellulose particulates are dispersed and reactivated in the hydrophilic liquid phase. A solid phase admixture can be added as a fine powder. The thermostable filling is desirable for use in methods for making co-extruded or co-laminated products of multi-textures.

Abstract: A highly colored dye wastewater is treated by a sequence of steps to obtain a color reduction of 90 percent or more. The method requires acidifying the wastewater and adding a cationic flocculant. A reducing agent is then, optionally, added to further reduce the color value of the wastewater and produce an oxidation-reduction potential of at least -200 and, generally, about -400 to -800. The reducing agent is, preferably, either a hydrosulfite or both a bisulfite and an alkali metal borohydride.

Abstract: A method of manufacturing an extruder barrel is disclosed which fabricates a barrel in two longitudinal sections and joins the sections together by electron beam welding. In a preferred form, the barrel sections are formed by machining conical recesses longitudinally in each section whereby a complementary bore is defined by the assembled barrel sections. The machined recesses may be formed with spiral, longitudinal or radial grooves. The recesses may be a uniform conical shape, stepped conical or a dual tapered shape.

Abstract: A Heater-Cooler unit that provides efficient heating and cooling in such a manner that the temperature is easily controlled. The unit's 360 degree exposure enables both fins and barrel surface to be in complete contact with cooling air. The structure of the fins provides contact with the barrel to conduct heat flowing from the heating elements to the barrel surface.

Abstract: A process for preparing low molecular weight alcohols from synthesis gas employing a homogeneous catalyst system of a ruthenium carbonyl complex and rare-earth containing complex.

Abstract: Zinc rich, solvent resistant and corrosion resistant coatings are prepared by blending zinc pigment, a thermoplastic polyhydroxyether and an organic dianhydride or polyanhydride.

Abstract: Purified isopropanol is obtained from a crude reaction mixture by removing high boiling oils with activated carbon, extraction with a high boiling solvent and distillation with energy saving use of distillation vapors to heat successive distillation steps. Recyle of components also improves the overall economics of the process.

Abstract: The continuous cobalt catalyzed liquid-phase oxidation of butane to acetic acid with oxygen has been improved by limiting the amount of iron, water and succinic acid present and maintaining a minimum of about 0.1% of cobalt acetate catalyst in the reaction medium.

Abstract: Olefins can be hydrated to the corresponding alcohols with a hydration catalyst comprising a calcined support consisting of diatomaceous earth, bentonite, silica, cornmeal and cellulose which has been calcined and then impregnated with phosphoric acid.

Abstract: Vinyl acetate in ambient air is measured by first drying the air sample, then adsorbing the vinyl acetate on an adsorbent containing a polymerization inhibitor, followed by desorption and assay of the desorbed vinyl acetate.

Abstract: Ambient temperature curable compositions comprising a hydroxyl containing organic polymer and an aminoorganosilicon acylamino compound, said compositions being useful as protective coating compositions.

Abstract: Blends of vinyl chloride polymers containing no carboxyl groups and about 10 to about 30 percent by weight of an ethylene/vinyl alcohol copolymer containing greater than 50 mole percent of vinyl alcohol therein provided excellent barrier packaging materials.

Abstract: Sulfur dioxide can be adsorbed from gas mixtures using cross-linked, water-insoluble polymers of N-glycidyl piperazine or N-glycidyl polyalkylpiperazines as the adsorbents.
