Abstract: The invention consists of a device called a feed, or wash box for use where it is necessary to feed a relatively large volume of slurry or liquor on to a moving surface uniformly and without excessive local velocity or turbulence, the device being characterized by the fact that it takes advantage of the moving slurry or liquor to receive it on an inclined plane, causing it to develop some velocity as it passes down the plane and spreads out, and at the end of the incline, causes it suddenly to change direction of flow by about 90.degree. and again by impact on another guide surface to change direction of flow by about 180.degree., to be fed on to a final surface, which may be a filter belt or other receiving surface.

Abstract: A process for recovering cyanuric acid values from a reaction mixture wherein salts of chlorinated isocyanuric acid, dichloroisocyanuric acid, and trichloroisocyanuric acid, isomers and mixtures have been formed and which have been treated to convert them to cyanuric acid values in solution, the recovery process comprising contacting the foregoing reaction mixture with an alkali metal cation in a pH range of from about 7 to about 11.

Abstract: Saturated polyester compositions stabilized against thermal degradation by the addition of small amounts of a synergistic stabilizing combination of a 5 or 6 membered, cyclic organic carbonate and an antioxidant selected from the group consisting of certain alkylated phenols, polyphenols, alkylphosphites, arylphosphites, aromatic amines and aromatic polyamines.

Abstract: A process for rendering synthetic materials, of synthetic fibers or mixtures of the same flame resistant which entails employing water insoluble flame retardant agents which are treated as colorless pigments, reduced to extremely finely divided condition, suspended in aqueous medium and applied as such or as part of a dispersed dye paste to the fabric, dried and set in place.

Abstract: An adhesive composition suitable for laminating thin foils to substrates, especially paper, is disclosed consisting essentially of an aqueous solution of a carboxylated vinyl acetate copolymer and a compatible, foil adherent, latex adhesive. These adhesives have the unique viscosity, drying, and adhesive properties required of foil laminating adhesives which were previously available only in foil laminating adhesives incorporating a casein thickener.

Abstract: A process for setting hair is disclosed comprising the steps of applying to the hair a solution of sulfonated polymer selected from the group consisting of sulfonated polystyrene, sulfonated interpolymers of styrene and ethylenically unsaturated comonomers, and soluble salts of said sulfonated polymers, setting the hair in the desired configuration, and allowing the hair to dry while it is retained in the desired configuration.

Abstract: Disclosed is an automatic control system for condition-responsively switching over audio signals from transceiver, radio or tape recorder. It is characterized in that a transceiver squelch control circuit having a transistor is connected through its collector electrode to a radio or tape recorder audio signal switching transistor at the base electrode thereof, thereby voltage variation in the squelch control circuit is transmitted to the radio or tape recorder audio signal switching transistor which in turn functions to switch off the radio or tape recorder audio signal.

Abstract: Water-soluble homo-and co-polymers of styrene and salts thereof having a degree of substitution from about 0.7 to about 1.3 sulfonate groups per unit of styrene are useful for treating gastric or duodenal ulcers.

Abstract: A process for rendering natural and synthetic materials and blends of the same flame retardant which entails treating the same with an aqueous dispersion of the flame retardant agent reduced to a finely divided state suspended in a latex medium and applied to the material with a finely divided metal oxide as synergist, by any convenient means; dried and set in place by baking. The active flame retardant agents are chlorinated cyclopentadieno compounds, chlorobrominated cyclopentadieno compounds, applied alone or in admixture with each other, or in admixture with brominated cyclopentadieno compounds, and in admixture with metallic oxides. The active flame retardant agents are reduced to a fine state of subdivision, preferably under 2 microns average particle diameter.

Abstract: A process for recovering cyanuric acid values and chlorine from the effluent mother liquor occurring in the preparation of an alkali metal or alkaline earth metal salts of dichloroisocyanurate or dichloroisocyanuric acid or trichloroisocyanuric acid, the foregoing recovery process comprising reacting dichloroisocyanurate acid or trichloroisocyanuric acid present in the foregoing effluent with a strong mineral acid.

Abstract: This invention relates to a rapid method for drying foodstuffs and the foods dried thereby. In particular, the method disclosed involves comminuting the foodstuff, blending therewith starch in an amount of 20 to 96% by anhydrous weight of the total mixture and drum drying to a desired moisture level. The resulting dried and extended foodstuff is superior to conventionally dried foodstuffs in color, fragrance, flavor retention and storage stability.

Abstract: A cold water resistant adhesive composition is disclosed which exhibits an optimum balance of cold water resistance and removability when employed for labeling of bottles which will be used under conditions of extreme humidity. The adhesive comprises a mixture of starch, styrene-maleic anhydride resin, peptizer, water and sufficient alkali to obtain a pH of 8.0 to 11.0 with at least 20% of the alkali present in the form of a "fixed alkali".
