Counter cross flow for an automatic tray processor

An apparatus for processing photosensitive materials, said apparatus is characterized by:

• a container which contains a channel through which a processing solution flows, the entrance and exit of said channel are upturned to contain processing solution within said channel;
• means coupled to said channel for transporting the photosensitive material from the channel entrance, through said channel, to the channel exit, said channel and said means are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between said channel and said means;
• means for circulating the processing solution through the small volume and said container;
• at least a first and a second slot nozzle coupled to said circulating means and forming a portion of said channel for controlling the velocity and amount of processing solution that dynamically impinges on the surface of the photosensitive material;
• a first conduit that is connected to one end of said first slot nozzle and said circulating means so that processing solution may travel in said first slot nozzle in a first direction;
• and
• a second conduit that is connected to the other end of said second slot nozzle and said circulation means so that processing solution may travel in said second slot nozzle in a second direction.
