Abstract: A pure, smooth microcrystalline cellulose bulking agent for oil containing foods such as nut butters, chocolates, cream containing foods, mayonnaise, and salad dressings. The bulking agent having a loose bulk density greater than 0.40 and a oil absorptivity of less than 1.0.
Abstract: Repulping and/or decolorizing formulations and mixtures which include a catalytic amount of a salt of a metal such as copper, iron, silver, or nickel; a persulfate; and from 0-10% saccharide. Formulations containing a carbonate, sesquicarbonate or bicarbonate for adjusting pH are preferred. A method of repulping and/or decolorizing broke, whether containing wet strength resin or not, using the formulations or mixtures of the ingredients in the formulations.
Abstract: The present invention provides a method for preparing a spray-dried compressible granular formulation for preparing pharmaceutical tablets in which hydrolyzed cellulose is used as a granulation aid, the resulting granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1 to 97% by weight pharmaceutical active, from about 3 to 99% by weight hydrolyzed cellulose, based on the dry weight of the granulation, and optionally conventional granulation and/or tableting additives such as surfactants, disintegrants and antiadherents/flow aids.

Abstract: An alkali metal peroxydisulfate or caroate can be used alone or in combination to destroy haloform present in an aqueous system. The destruction results in a reduction in the amount of haloform in the system. In another aspect, uv light and the peroxydisulfate and/or caroate can be used together to destroy the haloform present in the aqueous system.

Abstract: A particulate co-processed unattrited microcrystalline cellulose:hydrocolloid composition wherein the respective components are present in a weight ratio of from about 99:1 to 70:30. The composition is useful as a spheronizing agent for producing spheroids of uniform size and sphericity and having high drug loadings. The composition is produced by drying a slurry of the microcrystalline cellulose in an aqueous solution of the hydrocolloid. The preferred hydrocolloid is methylcellulose.

Abstract: A composition containing a persulfate and a carbonate, a bicarbonate or sesquicarbonate, which composition is suitable for oxidizing wet strength resin based broke used in wet strength paper. The combination decreases the time required for effectively repulping broke from such paper. Additionally, the combination is a single product capable of beaking down the wet strength resin and adjusting or maintaining pH at a predetermined value without additional chemical treatment.

Abstract: A process is described for solution mining isolated, mechanically mined-out areas of soluble evaporite ore to recover remaining ore reserves, wherein the mined-out areas are separated from an operational mine area by barrier pillars of the evaporite ore, by drilling at least one vertical well bore from the surface to a predefined distance above the evaporite ore body, converting the drilling of the vertical well bore to a substantially horizontal well bore at a predetermined distance below the ground level, continuing the drilling parallel to and within the evaporite ore body to form a well bore one end of which is connected to the mined-out area, developing a connection from the operating mine area to the other end of the well bore, drilling an injection well from the surface into the mined-out area, injecting an aqueous solvent into the injection well, passing the solvent into the mined-out area, removing solvent enriched in dissolved evaporite ore from the mined-out area, passing such enriched solvent from
Abstract: A process for fractionating agaroid compositions by dissolving the agaroid in a glycol, precipitating a first fraction by cooling and precipitating a second fraction by incorporating a nonsolvent to form two fractions substantially more soluble in water than the initial agaroid. Optionally the solubility of either fraction can be converted to conventional solubilities.
Abstract: A process for purifying elemental phosphorus, by dosing a multi-phase elemental phosphorus system, having an aqueous phase and an immiscible, elemental phosphorus phase containing antimony, with a conditioning agent selected from the group consisting of iron (II) salt or iron (III) salt with free iodine; iron (II) iodide; free iodine; iron (II) sulfate; or iron (III) sulfate in an amount effective to lower the amount of antimony in the phosphorus; agitating the resultant mixture at a temperature above the melting point of phosphorus, but below the boiling point of water, and then separating the aqueous phase from the phosphorus phase to recover a phosphorus lower in antimony content.
Abstract: A process for making gel bead having a mean diameter of less than 50 microns by adiabatically atomizing a hydrocolloid sol to droplet of less than 50 microns under conditions that lower the temperature of the hydrocolloid below its gel temperature.

Abstract: A method for sanitizing a fowl that has been defeathered and eviscerated by contacting the fowl with peracetic acid solution containing from 100 to 2000 ppm peracetic acid. Completely contacting the fowl with peracetic acid solution effectively reduces the bacterial level found on the fowl to a level that will not produce disease in human beings.
