    摘要: Pump chambers usable in beverage makers, for example, have a liquid-contacting heated surface provided with abrupt discontinuities--e.g. sharp edges or corners--to promote flaking-off of mineral deposits. These edges may be fins of rectangular or triangular cross-section.

    摘要: Disclosed is a process for the coupling of a Grignard reagent RMgX with an allylic halide in the presence of a dipolar aprotic solvent wherein the improvement, for obtaining improved yield and selectivity, comprises adding a catalyst to said Grignard or allylic halide and then carrying out the coupling reaction by the addition of the Grignard reagent to the allylic halide, said reaction being characterized by the displacement at the gamma position (relative to the halide) of the allylic halide with R of the Grignard reagent, migration of the allylic double bond in the direction of the halogen atom and loss of halogen. The present invention also resides in the discovery of certain novel procedures for the synthesis of Vitamin E. Specific embodiments of this aspect of the invention reside in the syntheses of 6,7-dehydrophytol, 10,11-dihydrofarnesene, phytone, hexahydropseudoionone, and related compounds as precursors for Vitamin E.

    摘要: An opacified latex paint comprising acrylic film-forming latex binders in combination with minor amounts of opacifying pigment and substantial amounts of non-film-forming polymeric particles (plastic pigment) provides a latex paint composition having desirable film integrity properties. The plastic pigment latex paint is compounded at a substantially high pigment-volume-content (PVC) greater than 75% PVC and yet produces a continuous crack-free paint film even though the dried paint film is highly loaded with non-film-forming components. The opacified paint films maintain excellent physical properties such as scrub resistance, burnish resistance, mar resistance, stain resistance, and other desirable paint film integrity properties.

    摘要: A process for dispersion strengthening metal alloys comprising the steps of separating metal powder particles larger than about 180 microns, flattening the particles to provide flake particles having a thickness less than 180 microns, and then internally oxidizing the flake particles. The flaked particles can be combined and consolidated with atomized particles less than about 180 microns on a 20% to 80% and preferably 40% to 60% weight basis to provide improved dispersion strengthened metal products.

    摘要: An electrocoating composition useful for electrocoating a paint coating from an aqueous solution onto an anode electrical conductive substrate. The electrocoating composition is based upon a fatty acid ester and .alpha.,.beta.-unsaturated dicarboxylic acid modified styrene-allyl alcohol copolymer further modified with an acid-functional acrylic copolymer. The electrocoated film can be air dried or heat cured.

    摘要: A particulate slagging composition of glass network formers and fluxing agents therefor serving as a protective layer on the top of a pool of molten steel at the upper end of an open-ended continuous casting mold. Such particulate slagging composition is characterized by the absence of lithium, the inclusion of at least about 1/2 weight percent potassium oxide equivalent, and the flowidity and fusion range upon melting suitable for the continuous casting of a steel.
