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: A process for removing arsenic from aqueous mediums by adding, in the presence of phosphorus, sufficient calcium hydroxide to adjust the aqueous medium to a pH of from about 7.0 to 11.5, whereby precipitates of both arsenic and phosphorus are formed and are subsequently separated from the aqueous medium. As a secondary treatment, calcium salts of arsenic and phosphorus in oxidation states lower than +5, and thus dissolved in the aqueous medium are oxidized, as by the addition of chlorine or hypochloride to such medium, and thereby converted to more insoluble forms which are separated from the aqueous medium as precipitates.

Abstract: This specification discloses a vapor phase process for oxidizing acetaldehyde to peracetic acid, acetic acid being formed as an additional product. Oxygen is used as the oxidizer at concentrations of less than 10% by using excess acetaldehyde and diluting the reaction with recycle gas. Initial mixing of the oxygen with acetaldehyde is done in an explosion-suppression chamber prior to introducing the reaction mixture into a reactor.

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 storage-stable bleaching detergent composition is obtained by adding, to a typical solid detergent mix, sodium perborate or sodium carbonate peroxide as a bleaching agent, and from about 50% to about 100% of the weight of the sodium perborate of an activator of the group consisting of the acetylated adduct of nitromethane and cyclohexanone, and the acetylated adduct of nitromethane and cyclopentanone.

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: Process for producing high bulk density sodium carbonate monohydrate crystals from sodium carbonate solutions wherein the sodium carbonate monohydrate is crystallized in the presence of at least 30 parts per million soluble aluminum ions.

Abstract: Manufacturing dry, free-flowing crystalline sodium carbonate peroxide by passing a gas stream at a temperature between 70.degree. and 150.degree. C into a drying zone containing moist sodium carbonate peroxide while maintaining the exit gas stream temperature between 50.degree. and 130.degree. C until the sodium carbonate contains between 0.05% and 0.5% by weight moisture, immediately passing the dried material into a cooling zone where the sodium carbonate peroxide temperature is lowered to between 0.degree. and 40.degree. C, and removing a dry, free-flowing, crystalline sodium carbonate peroxide product containing between 0.001% and 0.20% by weight moisture.

Abstract: Process for purifying crude cyanuric acid whereby crude cyanuric acid is digested with an aqueous phosphoric acid solution containing about 10% to about 85% phosphoric acid at a temperature of about 180.degree. C to about 220.degree. C under at least the autogenously developed pressure to digest the crude cyanuric acid. A novel, large, free-flowing cyanuric acid product is recovered free of any hard cement-like masses.

Abstract: Improved dry cleaning formulation containing a dry cleaning solvent, water, inorganic polyphosphate salt, hydrogen peroxide and a suitable detergent surfactant having a pH value of from 5 to 9, which minimizes equipment corrosion and maintains fabric strength while effectively removing hydrophilic stains.

Abstract: Textile fabric stain removal is significantly improved by including in conventional dry cleaning solvent baths, a preformed or in situ generated peracid.

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: Organic substrates stabilized against oxidative deterioration by the use of high molecular weight hindered phenols based on the condensation of a nitroalkane with either a dialkyldithiocarbonate or with formaldehyde and a di-t-butylphenol or a substituted derivative of a di-t-butylphenol.

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.

Abstract: A new class of chemical compounds useful for the control of insects consists of (methyl)(aminosulfenyl)carbamic acid esters of 2,3-dihydro-2,2-dimethyl-7-benzofuranol. The preparation of these compounds having a variety of (substituted-amino)sulfenyl groups, their physical properties, formulation, and use to control both household insects and crop pests are exemplified.
