    Abstract: Liquid anti-oxidants made by mixing specific chemical compositions disclosed herein, followed by thorough stirring so that a homogeneous blend of colloidal-like solutions are obtained. Such liquid anti-oxidants are applied to the surface of the carbon-carbon composite that is needed to be protected against oxidation by brushing, dipping, spraying, or other painting techniques, and allowed sufficient time for the anti-oxidants to penetrate into the subsurface region of the composite and to let dry in a dry atmosphere. The coated carbon/carbon composites can be heat treated (or charred) at a temperature of about approximately 650 to 950° C. for a time period of about approximately one to seven hours. The above painting/heat treating processes can be repeated one to three or more times in order to obtain sufficient anti-oxidant char on or below the surface to a certain depth of the composite.

  • Patent number: 4402908
    Abstract: Heat loss and evaporation from contained bodies of water are reduced by generating a cured polysiloxane foam on the surface of the water. The foam is formed by reacting an organohydrogenpolysiloxane with the water in the presence of a rhodium catalyst or an inhibited or chelated platinum catalyst.

  • Patent number: 4386052
    Abstract: A very effective composition for inhibiting vapor losses of stored hydrocarbons comprises a mixture of a surfactant, such as a foaming agent, and a polyglycol. A method for retarding evaporation of volatile hydrocarbons from a body of liquid hydrocarbon material is provided by forming a thin film of these compositions on the surface of the body of liquid hydrocarbons.

  • Patent number: 4345079
    Abstract: Scoopability of triethylene diamine (TEDA) is improved by admixture therewith of a minor quantity (about 0.5 up to 2% by weight) of an additive in liquid form. The types of additives described are liquid glycol compounds selected from among polyethylene glycols, glycol esters, glycol ethers and amino alcohols. Preferred additives are: Carbowax polyethylene glycols having the general formulaHOCH.sub.2 (CH.sub.2 OCH.sub.2).sub.x CH.sub.2 OHwherein x is about 3 to about 13, glycol diacetate and triethylene glycol diacetate.

  • Patent number: 4306994
    Abstract: A dry composition is described which can be converted to an anti-sticking composition for unvulcanized rubber by dispersion in water, consisting essentially of a film forming clay (bentonite or attapulgite), a surfactant and an additive capable of inactivating calcium and magnesium ions (e.g. polyphosphate); optionally, there may be present a defoamer, and up to equal parts by volume, based on a film forming clay, of a filler to speed drying.

  • Patent number: 4288460
    Abstract: Granular water-soluble food ingredients which deteriorate upon exposure to the atmosphere, such as hygroscopic organic acids which cake or coloring agents which oxidize, are protected by encapsulation in a protective coating consisting essentially of 5-37% a fatty acid derivative selected from the group consisting of polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monostearate and lecithin, 15-56% propylene glycol and 38-62% flow agent, e.g., fumed silica or carboxymethylcellulose. The resulting coated particles have a long shelf life and still are substantially instantaneously soluble in water.

  • Patent number: 4284601
    Abstract: Aqueous foam compositions comprising water and a mixture of ammonium lauryl sulfate, methyl polyoxyethylene cocoamine chloride, dimethyl cocoamine oxide and polyvinyl alcohol are used to suppress the formation of fumes from fumable materials by covering the material with said compositions in the form of foam, thereby causing the material to react with the water to prevent fume release.
