Abstract

294,996. Kõstner, J. G., and Tr÷ger, C. H. Aug. 3, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 4, 1928]. Tanning under abnormal conditions of pressure or rarefaction (including treating with gases under pressure); bates and like softening materials; electric currents, radiations, and the like, use of in tanning processes; currying and like finishing. -The penetration of hides by tanning liguors is facilitated by the use of alternations of increased and reduced pressure at a rate of more than ten times per hour up to 300 times per minute. Substances of known use as bates, bacterial cultures, yeasts, gases such as carbon dioxide and nitrogen, electronic radiations from radioactive substances or tubes, filtered spectrum radiations, and electric currents may be used in conjunction with pressure variations. Colloids, especially an extract of carob beans may be used with the tanning liquor. Specification 294,997 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the agents referred to may also be used to facilitate oiling or greasing of chrome leather. This subject-matter does not appear in the Specification as accepted.
