Abstract: A grind charge of cupreous particulates containing a major proportion of cuprous and cupric oxides and a minor proportion of elemental copper, said charge having average particle size above 15 microns, is subjected to high energy comminution with concomitant crystal lattice distortion until the average particle size of said particulates is no larger than 15 microns. The resulting catalyst, of fairly high specific surface area, can be used for alkyl or aryl halosilane production.

Abstract: Improved catalyst is made by including in a grind charge of cupreous particulates a small proportion of hydrated refractory metal oxide such as hydrated alumina. Said grind charge contains a major proportion of cuprous and cupric oxides, a minor proportion of elemental copper, and up to about 10% of promoter material. Such charge is subjected to high energy comminution with concomitant crystal lattice distortion. The catalyst is useful for the production of alkyl and aryl halosilanes.

Abstract: The present invention relates to liquid soaps for use in paper re-cycling and other industrial cleaning or scouring processes.The liquid soap comprises an aqueous partially saponified mixture comprising 1 part of pine oil (a mixture of terpene alcohols and hydrocarbons) and from 1 to 20 parts of a soap-making fatty acid, such as tall oil or distilled oil. The mixture is preferably saponified by use of 30% sodium hydroxide solution. The liquid soap may contain less than 10% water.

Abstract: There is provided an improved process for producing biologically active arylterpenoid compounds useful to inhibit eclosion of pupae, e.g., fly pupae or mosquito pupae. The process is characterized by reacting a terpenoid material having a terminal unsaturated linkage, e.g., dihydromyrcene (3,7-dimethylocta-1,6-diene) with a lower alkyl Grignard reagent, e.g., n-propyl magnesium chloride to form a Grignard exchange product. The exchange product is then benzylated. Either a benzyl halide, e.g., p-isopropylbenzyl chloride, or a benzaldehyde, e.g., p-isopropylbenzaldehyde may be used. These compounds are specifically described in U.S. Pat. No. 4,002,769. They contain also a lower alkoxy group, e.g., methoxy. This can be introduced prior to the formation of the Grignard exchange product or at a later stage in the operation. Use of the exchange-type Grignard reaction enables elimination of several steps when producing the arylterpenoids from pinene as the terpene source, and consequent costs.

Abstract: There is provided a process for recovery of fatty acids from tall oil heads comprising the steps of neutralizing the acids with a mixture of a magnesium soap forming compound and an alkali metal soap-forming compound under fusion conditions, stripping out unsaponifiables and springing the fatty acids with a mineral acid.

Abstract: There is provided a new method for analysis of the size and/or distribution of particles emanating from a mother liquid by sedimentation in a rotating disc centrifuge, particularly a photosedimentometer. The method is characterized in that the spin fluid or medium is formed externally of the disc as distinct from being formed within the disc while it is rotating. The externally prepared spin medium is formed from at least two miscible liquids of different densities for example, methanol and water, in a manner such that they are substantially incompletely mixed whereby a density gradient is established in the spin medium. Thereafter the spin medium is injected into the disc while spinning at a given speed, and later the mother liquid is injected. Results are closely comparable to the buffered line start method described in U.S. Pat. No. 3,475,968.

Abstract: A process and a product produced thereby, for forming rod or bar or tube stock or strip, comprising a sheath and a densified dispersion strengthened metal core. Powdered dispersion strengthened copper is put into a metal can and compressively reduced to size and density. The relationship between the tensile strength of the core when fully densified and the cold worked tensile strength of the can is important to the nature of the product.

Abstract: There is provided a stabilized aqueous base tackifier composition characterized by the presence in an aqueous medium of a resinous tackifier composition having an acid number in the range from 30 to 150 and a softening point in the range of from -40.degree. to 150.degree. C., a minor amount of a nonionic or anionic surfactant and a minor amount of an elastomeric latex. There is also provided a method of stabilizing an emulsifiable tackifier composition which comprises adding to such composition, a minor amount of a surfactant and a minor amount of an elastomer.

Abstract: Substantially completely deoxidized, consolidated dispersion-strengthened copper stock of sizable cross section and particulates capable of being thus consolidated into such stock are shown. The stock exhibits ductility substantially greater than that of otherwise corresponding stock which contains about 100-500 ppm of available oxygen. Also shown is a staged powder deoxidation process using hydrogen or like reducing gas followed by the sequestration of remaining available oxygen with a minute proportion of diffusible, normally solid oxygen getter.

Abstract: A process for making piperitone from crude plinols involving hydrogenating the crude plinols to form dihydroplinols and dehydrating the dihydroplinols to yield an iridene. The iridene is then oxidatively cleaved at the unsaturation to form an acyclic dione. The dione is cyclized in the presence of a base to form piperitone.

Abstract: An essentially nonaqueous, water-rinsible, readily fusible vehicle for paste of powdered solder is comprised of a dispersion of flux consisting essentially of alkali metal hydroxide in liquid polyol and water soluble, normally solid synthetic wax.

Abstract: An entrained flow process for chlorinating fine iron-containing titaniferous powder with chlorine gas and/or organochlorides in the presence of fine porous coal-based reductant powder for obtaining product chlorides of titanium and iron wherein said both of said powders are entrained in and flow downwardly through a chlorination reaction zone at a temperature of at least about 800.degree. C. is improved by: (a) supplying fine titaniferous and reductant powders to said reaction zone at a rate sufficient for establishing and maintaining titanium, iron and carbon reactants therein in substantial excess over those stoichiometric for the complete reaction of the chlorine present; (b) employing as at least the major portion of fresh reductant feed reactive char having surface area of at least about 10 m..sup.2 /g.

Abstract: An inverting tow plaiter adapted to position tow onto a receiving end of a main conveyor in a series of overlying laps oriented to permit trouble-free removal of tow from the main conveyor discharge end. The plaiter comprises a continuous, moving canvas belt positioned above the main conveyor constrained to follow the downwardly extending semi-circular path, and a stationary housing spaced from the belt to define with the belt a curved chute of narrowing cross-section. The chute has a gap width at the chute upper end which is greater than at the chute lower end. Structure for depositing tow onto the canvas belt at the chute upper end in a series of overlying laps which extend transversely across the belt is provided.
