Abstract: A photographic sheet material processing apparatus. The apparatus comprises an upright vessel of flat configuration having a narrow chamber filled with processing solution in which the material may be inserted. An applicator nozzle, below the level of the solution and in communication with the chamber and operated by a pump, directs a stream of the processing solution in the chamber against the emulsion side of the material, resulting in a laminar flow.

Abstract: An apparatus for processing photographic sheet material is described. The apparatus comprises an upright vessel of cylindrical configuration having concentric walls which define a narrow chamber adapted to be filled with processing solution in which the material may be inserted. Radially extending channels are distributed in a circular pattern below the solution level, terminating in a nozzle for directing an impacting streams of the processing solution in the chamber against the emulsion side of the material, resulting in a laminar flow.
