Abstract: Thermoplastic polymer particles are converted to pellets by depositing the powder onto a moving platform, melting the particles and transferring the melted polymer to a pelletizer.

Abstract: Moving bed hydride heat pumps and pressure pumps are described in which a hydride-forming material is transported between two or more reactor vessels. Each vessel can be maintained at a predetermined temperature, and thus, the hydride-forming material may be heated or cooled by moving it into an appropriately heated or cooled reactor vessel. In this way thermal cycling of reactor vessels is reduced or eliminated. Both continuously operating and moving batch hydride pumping systems are disclosed.

Abstract: Protein-containing materials are treated at specified temperature and pH conditions for a suitable length of time to yield products which replace material such as egg solids and nonfat dry milk.

Abstract: A stable free sulfur containing mineral oil is produced in a two-step process. The first step of the process comprises producing a sulfurized solubilizing oil by reacting a lubricant oil with elemental sulfur until the uncombined sulfur content is less than about 0.5%. The second step comprising dissolving in the oil a quantity of sulfur such that the final concentration of uncombined sulfur is less than 2.0%.

Abstract: This invention relates to the preparation of the subject aqueous solution from a non-bromine manganous salt. More specifically this invention pertains to a critical order of dissolving such salt and elemental bromine and to the use of an anti-oxidant for the manganous ion to prevent its conversion to hydrated manganous dioxide: MnO(OH).sub.2. According to "A Comprehensive Treatise On Inorganic And Theoretical Chemistry", J. W. Mellor, Vol. XII at pages 189 and 259 (published by Longmans, Green and Co., 1947) hydrated manganous dioxide results from the oxidation of a solution of manganous salt with chlorine, bromine, hypochlorous acid, hydrogen peroxide, etc. Such oxidation of a solution of manganous acetate was specifically mentioned. Such hydrated manganous dioxide is described as a white solid product which upon standing in contact with air becomes a dark brown to black product identified as MnO.sub.2.

Abstract: A catalytic composition is produced by reacting in an aqueous medium, vanadium and phosphorus compounds together with a hydrogen halide and removing liquid from the resulting reactants to form a solid which in an improved manner is heated at a temperature of about less than 470.degree. C. to effect liberation of water of hydration from the solid and thereafter contacting with a reducing material selected from the group of carbon monoxide, hydrogen and hydrogen sulfide at a temperature of from about 300.degree. to about 600.degree. C. and in the substantial absence of gaseous oxygen other than that liberated from the solid. The specific reduction step as taught and claimed herein improves catalyst activity performance by increasing the catalyst conversion and selectivity to a desired oxygenated product, and the ultimate yield of the oxygenated product per quantity of feed component converted. It also minimizes formation of inactive VPO.sub.

Abstract: Water-soluble polyesterimide resin compositions are prepared by in situ reaction of a mixture of glycol and triol with organic diacid and trimellitic anhydride/aromatic primary diamine. The product is reacted with additional trimellitic anhydride for use as wire enamel in water-base solution and chelated ethanolamine titanate is added to the solution as a crosslinking agent.

Abstract: A novel supported catalyst for polymerization of ethylene or its mixtures with C.sub.3 to C.sub.8 terminal olefins composed of (a) the solid reaction product of a titanium (IV) or vanadium (V) alkoxide, a hydrated magnesium stannate and an alkylaluminum dichloride, and (b) an organo-aluminum compound promoter. The catalyst produces polyolefin in good yield without any substantial production of polymer fines and the catalyst is quite sensitive to hydrogen induced chain termination processes leading to improved molecular weight control and rheology of the polymer product.

Abstract: Disclosed are a process for the manufacture of metal dithiophosphates especially the neutralization of dithiophosphoric acids, and also the product made by such process. The process for the continuous neutralization of dithiophosphoric acid with metal base comprises contacting dithiophosphoric acid with metal base to form a neutralization mixture; passing said neutralization mixture through a static mixer in order to achieve mixing of the neutralization mixture and substantial neutralization of said dithiophosphoric acid; cooling the substantially neutralized dithiophosphoric acid; and recovering metal dithiophosphate.

Abstract: This application is directed to the regeneration of fixed bed granular media filters used for the clarification of liquids, after said filters have become unsuitable or inefficient due to the occlusion of oily substances. One such regeneration method comprises the steps of: backwashing the filter, draining the filter, contacting the filter with an aqueous alkali solution composed of sodium hydroxide dissolved in demineralized water, said solution having a pH value of about 10.5 or greater, at a temperature ranging from about ambient to about 200.degree. F, for a time sufficient to regenerate the filter, and backwashing the filter. Generally, the alkali solution comprises about 0.1 to about 50 weight percent aqueous sodium hydroxide and the contacting is conducted for a period of about 0.1 to about 10 hours.

Abstract: Apparatus for the vapor phase polymerization of at least one polymerizable monomer comprising:(a) a horizontal, stirred reactor of substantially circular cross section containing a centrally-located drive shaft extending longitudinally through said reactor to which are attached a plurality of adjacently located paddles, which paddles cause essentially no forward or backward movement of the particulate matter contained in said reactor and extend transversely within and to a short distance from the internal surfaces of said reactor, said reactor being divided into two or more individually polymerization-temperature controllable polymerization sections by one or more barriers constructed to allow free gas mixing within said reactor and control particulate movement between said sections;(b) driving means for said drive shaft;(c) one or more outlets for removal of reactor off-gases situated along the topward part of said reactor;(d) one or more vapor recycle inlets situated along the bottomward portion of said rea
