Abstract

238,870. Beckmann, H. Aug. 22, 1924, [Convention date]. Filtering-media.-Diaphragms for filters, &c. are made of spongy rubber produced by coagulating latex or suitably treating rubber dispersions to form a jelly-like mass which is then vulcanized to produce a rubber having pores of microscopic dimensions. The spongy rubber is made by mixing. latex or other rubber dispersions with sulphur and adding coagulating substances, such as solutions of magnesium or barium salts. The jelly-like mass produced is vulcanized in hot water or vapour.
