Abstract: A method of preventing sludge deposition in the treatment of geothermal steam condensate with iron catalyzed/hydrogen peroxide by carrying out the treatment in the presence of an inorganic polyphosphate.

Abstract: In a system of fluidized gasification of carbonaceous solids in which fines are burned in an external combustor to heat recycle solids, fines entrainment is reduced by introducing the finest of the fines into the combustor from the lower end of a fluidized fines feeder vessel whereby the said finest fines are selectively burned.

Abstract: The addition of an effective amount of a compound selected from the group consisting of hypophosphorous acid and salts thereof to cheese during manufacture prevents clostridial and coliform blowing and the formation of clostridial enterotoxins in cheese.

Abstract: The strength of phosphate shale agglomerates or briquettes is enhanced by adding to and mixing with crushed phosphate shale ore tempering water and a water-soluble alkali metal or ammonium phosphate. The water-soluble phosphate salt is preferably dissolved in the tempering water and the solution sprayed onto the crushed shale ore. The tempering water is added in an amount to bring the moisture content of the mixture between about 9 and 12%. The phosphate salt is added in an amount up to 0.1%. The mixture is compacted into desired size and the compacts calcined.

Abstract: A process and apparatus are described for collection of gases and particulates which arise during the feeding of an electric furnace, especially in the manufacture of phosphorus. The collection system for the gases and particulates includes novel explosion panels which are employed in an enclosure that contains the gases and particulates, and the use of such panels also in the ductwork and filter units that conveys and treats the gases and particulates from the enclosure. A further treating system also prevents moisture in the gases and particulates from clogging the filters used to separate the particulates from the gases. Also described is a novel furnace feeding system that can be used in cooperation with the gas and particulate collection system.

Abstract: The growth of Clostridium botulinum and the production of enterotoxin in corned beef and poultry products is inhibited by adding to such products an effective amount of a compound selected from the group consisting of hypophosphorous acid and nontoxic water-soluble salts thereof in combination with minor amounts of sodium nitrite.

Abstract: A smoked fish product, which inhibits the growth of Clostridium botulinum and the production of enterotoxin during storage of the smoked fish, containing an alkali metal nitrite salt and a compound selected from the group consisting of hypophosphorous acid and sodium, potassium, calcium, and manganese salts thereof.

Abstract: Smoked meat products which inhibit the growth of Clostridium botulinum and the production of enterotoxin during storage obtained by adding to the meat products an alkali metal nitrite salt, in an amount less than 120 parts per million, and from about 1,000 to about 3,000 parts per million of a compound selected from the group consisting of hypophosphorous acid and salts thereof.

Abstract: Derivatized agarose is produced by introducing into the disaccharide unit of the agarose polymer chain, at least one substituent having a molecular weight range greater than 100 to about 1,000,000. The derivatized agarose is useful as a sieving gel in electrophoresis and diffusive interactions.

Abstract: Compositions comprising organic phosphorus compounds having a peroxygen group which is either a hydroperoxyalkyl (H--OO--C--) group or a peroxyether (--C--OO--C--) group. There is at least one such group per 500 phosphorus atoms in the composition. These peroxygen compounds may be made by passing oxygen through a liquid comprising a phosphorus compound which has an aliphatic carbon, having an abstractable hydrogen, directly attached to a carbon of an aryl ring; for example, an isopropylphenyl phosphate. The peroxygen compounds may be added to compositions comprising peroxide-reactive organic polymers to increase flame resistance.

Abstract: In a fluidized coal gasification process in which heat for the gasifier is provided by recycle combustor residue from a slagging combustor, SO.sub.2 in the combustor's flue gas is removed by contacting the flue gas with the incoming coal feed whereby the SO.sub.2 is adsorbed on the coal and converted to H.sub.2 S in the gasifier. Sulfur is recovered from the H.sub.2 S in a Claus Plant.

Abstract: There are disclosed triaryl phosphate ester functional fluids, such as lubricants and hydraulic fluids, which contain as the oxidatively stable component, a mixed tertiary-butylphenyl/phenyl phosphate containing about 15 to 60% by weight t-butylphenyl radicals.

Abstract: This application discloses a process for manufacturing glycidol and, if desired, glycerol, by epoxidizing allyl alcohol with a 5 to 40% solution of peracetic acid in a substantially anhydrous, inert, organic solvent to produce glycidol in high yield and purity. Formation of by-products is minimized by rapid removal of co-product acetic acid. The glycidol can then be hydrolyzed to form a readily purifiable glycerol.

Abstract: Regenerated cellulose sponges of incresed absorbency and rate of absorption formed by impregnating the sponge material with a solution or dispersion containing from 0.005 to 0.25% of a water-soluble or water-dispersible, high molecular weight, hydrophylic, film-forming polymer, drying the impregnated sponge and compressing it. The presence of the film-forming polymer allows the cutting of desired shaped individual sponges from the treated sponge material with a minimal formation of lint particles on the cut surfaces.

Abstract: An improved process is described for producing glass in which a glass batch is mixed with a binder, aged, compacted, and compressed into briquettes, which are heated to partially react the contents of the batch in a prereaction stage. Prereacted briquettes are then placed in a fuel-fired furnace and heated at a temperature not above 2,600.degree. F (1,430.degree. C) to refine them into glass.

Abstract: Method of preparing refined, dense soda ash from crude trona by calcining the crude trona to crude sodium carbonate, mixing the crude sodium carbonate with an aqueous solution of soda ash or water to form a substantially saturated crude sodium carbonate solution containing coarse and fine insolubles, clarifying the crude sodium carbonate solution, passing the clarified sodium carbonate solution upwardly through an expanded carbon bed to remove organic impurities, evaporating the carbon-treated sodium carbonate solution to crystallize sodium carbonate monohydrate crystals, separating the sodium carbonate monohydrate crystals and calcining them to dense soda ash.

Abstract: A power strapping tool having an anvil and a tensioning wheel adapted to engage with overlapping portions of a strapping looped about a package and extending to a supply. The tensioning wheel is rotatable in a direction as to tension the loop of strapping and maintain such strapping tensioned while overlying portions thereof are connected to each other and then in an opposite direction to relax and flex away from the underlying strapping portion a span of the overlying strapping extending between such wheel and the location of strapping connection to thereby position such flexed, overlying strapping portion for easy severence. In the preferred embodiment, rotation of the tensioning wheel is also relied upon to effect projection of a knife between the overlying flexed and the underlying strapping portions and to then again tension the overlying strapping portion whereby the flexed strapping is urged against the projected knife to thereby sever the applied loop of strapped from its supply.

Abstract: A molding process for the manufacture of shaped carbon articles wherein a mixture of pitch, tar, finely-divided coke and microcrystalline cellulose is formed, the mixture compressed to form a shaped article, and the article calcined.

Abstract: Process of making a polyester resin using a zinc esterification catalyst and a hindered phenol stabilizer.

Abstract: A strapping machine for applying a tensioned strap loop horizontally about the girth of an object in which a yoke for lacing a strap about an object and means for tensioning and securing such strap are together adjustable as a unit, first into a desired projected position vertically of the object which is to be strapped, and then into a horizontal projected position in which the strap tensioning and securing means are directly adjacent to such object immediately prior to performing their respective functions.
