Abstract

509,403. Alkali containers for respiratory apparatus. SPOLEK PRO CHEMICKOU A. HUTNI VYROBU. Jan. 11, 1938, No. 852. Convention date, May 8, 1937. [Class 81 (ii)] [Also in Group III] The contents of alkali containers for respiratory apparatus comprise caustic alkali having -incorporated therewith a quantity, up to 10 per cent of the total mass, of one or more, preferably powdered, amphoteric metals, such as zinc, aluminium, lead, or cadmium, or compounds thereof, such as aluminium sutphate or zinc chloride, reactable with the alkali to form an alkali metallate. In an example, 2 per cent of aluminium sulphate is stirred into a hot liquid caustic soda melt and the mass cooled and granulated.
