Abstract

494,342. Photographic developing - apparatus. MORSE, S. H. April 26, 1937, No. 11829. [Class 98 (ii)] In a photographic apparatus for developing by ammonia or other gas, a sheet metal housing a encloses a developing tank g containing a rotary cylinder l of porous material, on to which the sensitized material is fed between a guide q and plate p and retained by an open-mesh wire belt m. The opening o in the tank is bounded by the plate p and a plate r perforated at v. After development, the sensitized material is delivered over a roller t into the space s. A heating element 1 is arranged below the tank, and liquid ammonia is supplied by a pipe 2. A fan x draws cold air through perforations v and up through space k, so that any condensation occurring in the tank must take place on the wall j thus cooled. Additional heaters 4, 5 may be provided. Specification,307,710, [Class 98 (ii)], is referred to.
