Abstract
491,237. Preventing incrustation and corrosion. MICHELIN & CIE. Nov. 24, 1936, No. 32184. Void. Convention date, Dec. 13, 1935. [Class 123 (i)] Incrustation and corrosion in hot water systems are prevented by the addition of trisodium phosphate, 1 part and sodium silicate 3 parts. The two salts may be fused together, cooled, and the vitreous mass broken up for use. An inert substance such as fine gravel may be added. When used in the cooling system of an internal - combustion engine, the mixture may be used in the form of a cartridge which is placed above the water of the radiator where it is dissolved by condensate. Anti-freezing substances in the water are not affected.
