Abstract

298,328. Cole, W. H. Aug. 22, 1927. Coating.-The process described in Specification 289,906 is carried out at a pressure above atmospheric and at a temperature higher than the boiling point of the liquor in a stationary or movable autoclave. The proofing solution may also be prepared in the autoclave.
