Abstract: In accordance with the instant invention, a high solids phthalocyanine pigment presscake prepared by methods well known to those skilled in the art is fluidized. The fluidization process comprises the steps of mixing the high solids pigment presscake with alkali metal hydroxide or ammonium hydroxide and rosin. In a preffered embodiment, the rosin, is dissolved in the hydroxide or aqueous solution thereof prior to mixing with the presscake.
Abstract: Use of an ink composition containing an organopolysiloxane having at least one hydrophilic group can bring about such a lithographic printing using a dampening solution as the non-image area is hardly stained, the image area is given a sufficient density, emulsification hardly occurs and tolerance for change of printing conditions is high.

Abstract: Improved coating compositions are described for the protection of superalloys at elevated temperatures. The coatings are of the MCrAlY type where M is nickel or cobalt and are significantly improved by the addition of from 0.1-7% silicon and 0.1-2% hafnium. Coatings of the invention are preferably applied by plasma spraying and as so applied are found to be substantially more effective than prior art coatings.
Abstract: A recording liquid comprises a dye selected from C.I. Direct Blue 199, C.I. Direct Yellow 86 and C.I. Food Black 2 as the recording agent for forming an image and a liquid medium for dissolving or dispersing said recording agent therein, said liquid medium comprising at least: (a) either one or both of polyethylene glycol and polyethylene glycol monomethyl ether, (b) either one or both of diethylene glycol and sulfolane, (c) either one or both of N-methyl-2-pyrrolidone and 1,3-dimethyl-2-imidazolidinone and (d) water.
Abstract: A reversible liquid/solid phase change composition for storing thermal energy. The composition comprises at least one hydrated inorganic salt selected from a salt or mixture of salts that are subject to segregation of its chemical components during repeated freezing and thawing cycles, and a surface active thickening agent in the form of a cationic surfactant and selected from an amine, salts of the amine, or a quaternary ammonium salt of the amine, wherein the thickening agent is present in the hydrated salt in an amount sufficient to form a micelle structure throughout the hydrated salt to prevent such segregation.
