    摘要: The present invention relates to a process of fabric cleaning utilizing a solvent emulsion which effectively combines the dissolving and suspending power of water for hydrophilic substances with the dissolving power of organic compositions for hydrophobic substances. The factor lending economic practicability to the process is the breaking of the emulsion after it has performed its cleaning function whereby only the organic fraction thereof undergoes distillation cleansing.

    摘要: A method of metallizing materials by coating a substrate material with a hydrophilic composite material; chemically plating said hydrophilic composite material with a metal to render the surface conductive; followed by electroplating a metal onto the conductive surface. The method can be, for example, utilized to produce metallized foams, embossing plates for reproduction of grains and textures, and decorative coatings for substrate materials.

    摘要: A formulation which consists essentially of from about 20%, by weight, to about 87%, by weight, zinc oxide, from about 13% to about 80%, by weight of a selected type of acidic pH adjuster, and from about 0% to about 7%, by weight, of trimagnesium phosphate, when incorporated in fluorine-containing toothpaste formulations which also contain at least one compound selected from the group consisting of an insoluble alkali metal metaphosphate and calcium pyrophosphate, yields a smooth paste having a pH of from about 5.5 to about 6.8 which will not corrode the inside of unlined aluminum tubes containing such a formulation. When the components of the formulation are based on the weight of the entire toothpaste formulation, said zinc oxide can be present at from about 0.05% to about 2.0%, the acidic pH adjuster can be present at from about 0.05% to about 3.0%, and the trimagnesium phosphate can be present at from about 0% to about 0.5%.

    摘要: Metal alkoxides, such as antimony glyoxide, are produced in the anolyte of a compartmented electrochemical cell, characterized by the seperation of the anolyte from the catholyte by an anion-exchange membrane. The anode comprises the sacrifical metal; the cathode is an indifferent material. Monohydric metal alkoxides also can be produced.
