Abstract

365,971. Filtering - media. BECKMANN, H., 26, Albertinenstrasse, Zehlendorf, Berlin. June 26, 1931, No. 18573. Convention date, Aug. 2, 1930. Addition to 238,870, [Class 46, Filtering &c.]. [Class 46.] Corrugated porous rubber sheets for use as filters &c. are obtained by coagulating latex to form a sheet of jelly, partly vulcanizing this without applying pressure or permitting the evaporation of the contained water, corrugating the sheet by known means, and then completing the vulcanization while avoiding evaporation of water.
