Abstract

187,805. Kumagae, S., and Chiba, T. Sept. 26, 1921. Pulp, preparation of.-Waste printed paper is boiled in a solution containing soap, hyposulphite of soda, and a waste fluid known as "tofu whey," which remains after preparing a food of Japan and China known as " tofu " from the soya bean. The printing ink is thus loosened, and is removed by beating and washing.
