Abstract

1,142,430. Photographic developing apparatus. GENERAL ANILINE & FILM CORP. Nov. 2, 1967 [Nov. 3, 1966], No. 49840/67. Heading G2A. A developing apparatus has a pair of chambers 19, 19' vertically spaced apart, into which an exposed sensitive sheet is fed by rollers 11, 11', an ammonia water-vapour mixture being supplied under pressure along the path of motion of the sheet so as to float the sheet as it is moved towards exit rollers 18, 18'. Wipers 21, 21'and 28, 28' contact the rollers so as to seal the space between the chambers from the atmosphere. Gas enters the chambers through perforated tubes 24, 24' and after use is drawn out of the space by ducts 25, 25' and is continuously re-circulated by a blower 38. A gas mixer having a closed heated vessel 31 to which anhydrous or aqueous ammonia can be supplied is provided. A water level vessel 33 is provided to maintain the water level in vessel 31 constant. A sump 43 supplies water to the vessel 33 when anhydrous ammonia is used, and a drain 45 is provided for use with aqueous ammonia. If desired, only one perforated tube 24, 24' may be used, transfer slots being provided at the lateral edges of perforated sheets 20, 20' which define the space between the chambers, so as to deliver gas to both chambers. If a sheet with a length shorter than the distance between the roller pairs 11, 11' and 18, 18' is used, a pair of rollers may be inserted into the space to guide such a sheet.
