Abstract

255,030. Fish, F. K. July 7, 1925, [Convention date]. Pulp, preparation of.-In the preparation of pulp from wood, the material is digested with a liquor containing solvent extractives of plant material to which sulphur is added. Chemical agents such as soda, caustic potash, lime, and the like are used in addition, and the liquor is circulated and sprayed on to the material during the charging of the digester and during the cooking. A vacuum of 15-20 inches is maintained during the first part. Specifications 5157/11, 214,788 and 244,789 are referred to.
