Abstract
269,518. Soc. le Xylium. April 16, 1926, [Convention date]. Plastic compositions containing oxychlorides.- Magnesia cements are rendered impervious to moisture by the addition of an insoluble complex soap, e.g. a lead soap, and of a dispersing agent, e.g. casein, to maintain the waterproof substance in its colloidal condition until the composition has set. According to an example, 2-4 parts of an ammonium soap and casein and 4-6 parts of lead acetate are added to 30-35 parts of magnesia, 15-20 parts of sawdust, and 2-6 parts of loading substances (plaster, lime, silicia, &c.), and 30-40 parts of magnesium chloride are then added. The Specification, as open to inspection under Sect. 91 (3) (a) describes also the use of waterproof colloids other than insoluble soaps. This subject-matter does not appear in the Specification as accepted.
