Abstract: A method of freezing food products such as meat and poultry as well as vegetables and fruits, including the steps of cooling brine made up of propylene glycol, sodium chloride and water and then contacting the food product with the cooled brine. The food product is maintained in contact with the brine for a time sufficient to freeze the food to a desired temperature.

Abstract: A process for preparing meat products which may inherently contain trichinae parasites so as to insure that the product after treatment is free of live trichinae organisms. The process comprises the steps of subdividing the meat to expose trichinae to treatment conditions and contacting the subdivided meat with salt, forming the salted subdivided product and heating sequentially at a temperature and for a time sufficient to destroy the salt conditioned trichinae organisms but insufficient to adversely affect the texture of the meat.

Abstract: Live poultry, soon after hatching, are treated with a cryogenic fluid applied at the keel bone tip for a brief period sufficient to retard growth of the keel bone tip but insufficient to damage skin or tissue and thereby reduce breast blister and other dermal growths and increase the market quality of birds at maturity.

Abstract: Blends of certain block copolymers and epoxy resins, which have superior thermoplastic adhesive properties are disclosed. The blends are prepared by mixing hydroxy-terminated poly(ester/ether) block copolymers with epoxy resins. These unreacted blends are useful as hot melt thermoplastic adhesives having very high peel strength, high tensile shear strength, creep resistance at elevated temperatures, and good viscosity stability.

Abstract: Phosphate ora matrix is treated to recover P.sub.2 O.sub.5 values. The matrix may be the phosphate ore as it is mined, or it may be residue formed upon dewatering benefication slimes. Without being subjected to beneficiation, this matrix is slurried with an organic solvent in a slurry vessel. When the slurry is mixed with a strong mineral acid, a system having a single liquid phase is formed with the organic solvent serving as a vehicle for distribution of the mineral acid which in turn solubilizes P.sub.2 O.sub.5 values for their extraction from the matrix. Thereafter the P.sub.2 O.sub.5 values are separated from the solid phase and then removed from the organic solvent.

Abstract: A comb-like injection apparatus comprising a hollow manifold and a plurality of hollow tines extending therefrom, is inserted longitudinally of a poultry carcass between the skin and flesh, thereof, and the tines are forced into the flesh. The apparatus comprises a single hollow slender manifold having a plurality of hollow tines connected and extending perpendicular and comb-like to the manifold. The tines are spaced along two-thirds or less of a closed end of the manifold and have closed pointed ends. The hollow tines have orifices and the tines communicate with the hollow interior of the manifold. Thereafter, a liquid additive is forced through the manifold and tines and through orifices therein and ejected into the flesh.

Abstract: Screened and drained used lubricating oil stock is predistilled in a steam stripping still for about 4 hours or more. The thus predistilled used oil then flows to an evaporator for a vacuum distillation at a temperature below the cracking temperature of the stock, about 480.degree.-650.degree. F., to effect an evaporation of the used lubricating oil and its separation from a concentrate by-product of heavy lube hydrocarbons and additives.

Abstract: A polymeric compound having superior thermoplastic adhesive properties is disclosed. The compound is a poly(ester/ether) block copolymer which is extended with an anhydride to introduce carboxyl groups thereinto. Also disclosed are thermoset adhesives having superior properties and which are such carboxylated copolymers that have been crosslinked with a suitable resin.

Abstract: Wastewater treatment wastes, such as skimmings or sludges, are processed so as to reduce the water content by approximately two thirds and increase the impurities content thereof. The wastes are passed over a dense supply of very fine bubbles. These fine bubbles assist in floating impurities within the wastes to result in the formation of an upper stratum of gas, residual water and a concentrated impurities content and of a lower stratum that is primarily water, after which the upper and lower strata are separated.

Abstract: A hand grip comprised of hinged semi-cylindrical portions with internal latch means is fastened about a loop handle of a package.

Abstract: Canned meat items that are subjected to pasturizing temperature treatment are first treated with an enzyme, such as bromelin, which will tenderize the meat and then be inactivated by the pasturizing temperatures.

Abstract: A process for manufacturing isobutylidene diurea (IBDU) comprising reacting urea with isobutyraldehyde in an aqueous medium and in the presence of a protein-derived emulsifier and an inorganic ammonium salt.

Abstract: Food patties are severed from logs and fed into magazines. A plurality of logs may be processed simultaneously; and the severed patties may be simultaneously fed in columns into one or more magazines. Under certain conditions columns of patties are moved through a transition means to separate same prior to entering the magazines. Thereafter successive magazines are moved to a position where the patties are sequentially deposited from the magazines onto a divider web and conveyor.

Abstract: A protein food product having an expanded, elongated cellular structure similar to meat is prepared by forming a dough of about 15-45% water and undenatured oil seed flour of less than 3% fat. The dough is heated under pressure over a period of less than 5 minutes to a maximum temperature of 260.degree.-380.degree. F., whereupon it is extruded into the atmosphere. The pressure drop causes formation of an expanded cellular structure, while the extrusion elongates the structure. The product, when hydrated, simulates the texture of lean meat.

Abstract: An aqueous composition includes a normally biodegradable component and contains tertiary butyl hydroquinone to inhibit microbial growth. Oxidative rancidity is also controlled when the composition has a fat or oil content. A method is described which adds tertiary butyl hydroquinone to aqueous biodegradable materials in concentrations that inhibit microbial growth.

Abstract: Gelatin is extracted from collagen-containing substances by liquefaction with hydrogen peroxide as the sole lyotropic agent. Collagen-bearing tissue is liquefied through agitation with hydrogen peroxide at about 45.degree.-60.degree. C. for from about 4 to about 24 hours at concentrations such that the weight of peroxide is from about 1/3 to 3 times the weight of collagen protein within the system. The thus formed colloidal solution gels upon cooling, and gelatin degradation is minimized by removing peroxide from the solution before the gelatin is dried.

Abstract: Improved epoxy resins are prepared by the anhydride curing of an epoxy system containing three or more epoxy compounds, at least two of which are epoxidized fatty acid esters.

Abstract: A vegetable sauce containing a vegetable paste an edible fat and other ingredients is blended, heated, air is injected, and the sauce is chilled and extruded into congealed strand-like form.

Abstract: Raw wastewater to be clarified is routed in an apparatus which directs the wastewater in an improved upwardly directed vortex path that is above and open to a source of dense microbubbles. Impurities within the wastewater are urged toward the periphery of the vortex and coagulate, while the bubbles tend to pass up through a central core of the vortex. The coagulated impurities and the bubbles approach the outlet of the vortex apparatus, whereupon a venturi-like effect is developed to accomplish an improved contacting of the coagulated impurities and the bubbles to form buoyant agglomerates. The wastewater and buoyant agglomerates flow together through the vortex outlet, after which the buoyant agglomerates may be permitted to float to the surface of the wastewater in a separate chamber.
