Abstract: Non-conjugated para-menthadienes having one site of unsaturation at the 4(8)- or 8-position are hydrogenated to selectively form 3-menthene in the presence of a homogeneous ruthenium catalyst complex.

Abstract: A mass of fine particulates such as chlorinated by-products (often collected as "cyclone solids") from the chlorination of titaniferous material, said particulates comprising hydrolyzable metal halides, are converted to readily-handled granules by hydration and attendant agglomeration as heat and vapors evolve.

Abstract: A process for manufacturing prefinished hardboard includes the use of a pre-press sealer comprising an aqueous mixture of a polyvinyl alcohol polymer in conjunction with emulsified fatty acid and/or fatty esters, an amine or similar emulsifier, and aluminum stearate. The pre-press sealer provides excellent sealing and hardening fiber binding to the porous fiberboard surface as well as improving the release from the press after the fiberboard is formed in a press under heat and pressure.

Abstract: Frozen food products, such as fish, poultry and vegetable frozen products, suitable for micro-wave or oven cooking, which when cooked resemble in taste, texture and appearance fat-fried products, are prepared by coating frozen portions of said products with an edible oil containing a moisture absorbing substance such as pregelatinized starch, and then applying to the coated portions finely divided hygroscopic, crisp particulate, such as toasted bakery, cereal or carbohydrate particulate, capable on cooking of giving the appearance of a fat-fried product. The dilatometric profile of the edible oil is critical, and is such that the oil is fluid at room temperature but has a plastic consistency at the temperature of the frozen portions.

Abstract: Low-calorie imitation dairy products are obtained by elimination of the conventional triglyceride fat content and substituting therefor an edible partial glycerol ester emulsifier in which a major constituent is diglyceride, present in an amount of about 38-48%, based on the ester emulsifier weight. The triglyceride content is less than the mono- and diglyceride contents combined, the ratio of diglyceride to monoglyceride being about 5:1 to about 1.5:1.

Abstract: Tall oil containing anthraquinone is fractionally distilled for producing the tall oil heads cut enriched in said anthraquinone.

Abstract: A heat treating apparatus particularly useful for the drying/heat-setting and cooling of synthetic tow comprises first and second elongated housings with separate conveyors longitudinally positioned in said housings, the housings being at different temperatures. Means are provided to deposit a continuous length of tow on the conveyor of the first housing in an undulating pattern to define a substantially straight bed of tow having substantially uniform maximum thickness and width dimensions. A transfer device is provided between the first and second housings including a flat plate adapted to pick up the tow from the conveyor of the first housing, and integral therewith, an enclosed chute adapted to deposit the tow on the conveyor of the second housing, the chute having height and width dimensions substantially the same as the maximum thickness and width dimensions of the bed of tow. The transfer chute is adapted to air seal the first housing from the second housing.

Abstract: The compound d-isomenthoxyacetic acid and various ester and amide derivatives are useful resolving agents and perfume ingredients.

Abstract: Aqueous heat-curable coating compositions comprise polyester resin, aminoplast resin, and an allyl ether of a diol or triol wherein the allyl ether alcohol functions as a conventional co-solvent for aiding in dispersing the polyester resin in water and under curing conditions becomes an integral part of the cured coating.

Abstract: A boron-containing nickel or cobalt spray-and-fuse self-fluxing alloy powder contains hard precipitates of chromium boride and, optionally, chromium carbide which are internally precipitated from a melt of said alloy. Such alloy powder is made by atomizing the melt at about the temperature at which the melt is viscous.

Abstract: A direct connection provides coupled movement from a keylever to an interposer of a simple key action in a typewriter. The connection includes an abutment integrally constructed on the keylever inserted within a recess on the interposer to effect movement of the interposer when the keylever is caused to move. Depression of the keylever pushes the interposer downward against a pawl that will engage a rotating power roll to cause initiation of a print movement of a typebar. The keylever while being restored by an underlying spring, will then pull the interposer upward to rest. The keylever and interposer are in planar alignment that is maintained by having the connection contained within a slot of a support member in the typewriter.

Abstract: A low silhouette keyboard having a plurality of keylevers arranged in rows and in parallel relationship to one another are suspended, guided and biased to restore by opposing flexible support members. The keylevers are "T" shaped which includes a cross arm constrained between the flexible support members, and a leg portion which projects through slots in a single guide comb. The keylevers are suspended in cantilever fashion being biased upward limited by an upstop. Reciprocation of any keylever in any row is a path substantially perpendicular to the plane of the flexible support members. Keytouch of all keylevers is substantially simultaneous and uniformly adjustable by providing means for varying the upward biasing force applied thereto.

Abstract: An aqueous ferrous sulfate waste stream is converted into sludge and improved water effluent by a preferably ambient indoor temperature and pressure flow process comprising: turbulently mixing said stream with a substantial excess of gaseous oxygen and a small excess of impalpable calcium carbonate in a reaction zone until the iron content of said stream is virtually all sludged; classifying resulting sludge into a coarser solids fraction (a portion of which is recycled to the sludging operation) and an aqueous suspension of finer solids; and separating finer solids from such aqueous suspension. As such streams usually contain free sulfuric acid, it is desirable to first precipitate from the stream a primary gypsum product by neutralization prior to such sludging operation.

Abstract: Ferruginous titaniferous material is chlorinated with chlorine for producing a product stream of titanium chlorides and by-product metallic iron in a laminar flow process.

Abstract: Disclosed are novel diphosphonic acids and diphosphonic acid esters of para-menthane which may be prepared by reacting .alpha.-pinene or .beta.-pinene with a dialkyl hydrogen phosphite under effective free-radical conditions.These products are potentially useful as flame retardants and are useful as treating agents for improving the pigmentary properties of pigmentary titanium dioxide in thermoplastic formulations.

Abstract: Hydrogenated fatty acids are produced by hydrogenating a crude glyceride oil and splitting the resulting hydrogenated crude glyceride oil into component hydrogenated fatty acid and glycerine.

Abstract: Acyclic terpenoid onium salts are cyclized in an acidic aqueous solution at a temperature of at least about 80.degree. C.

Abstract: Certain terpenylaminoalkanol compounds have been found to be selective piscicides useful in controlling fish species populations including carp and white sucker.
