摘要:
Textured surfaces on respective walls of racks and tanks of photographic processing apparatus reduce the frictional forces between the photosensitive material leading edge surfaces and the walls of the racks and tanks. The processing solution flows through fissures in the textured surfaces, thereby providing a solution bearing layer between the photosensitive material and the textured surfaces. This allows a greater photosensitive material leading edge impact angle with the textured walls which allows the photosensitive material to change direction unimpeded.

An apparatus for processing photosensitive materials, which comprises: a tank through which a processing solution is to be pumped; a rack having integral means to facilitate its insertion and removal from the tank, the rack and the tank are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the rack and the tank; means for circulating the processing solution through the small volume; a first plurality of rollers for moving the photosensitive material into or out of the small volume; a second plurality of rollers connected to the rack; a third plurality of rollers connected to the tank, wherein the second and third plurality of rollers move the photosensitive material through the small volume; means for driving the second plurality of rollers; and means for preventing processing solution from flowing between the driving means and the second plurality of rollers to reduce the space that would otherwise be filled by the processing solution.

摘要:
A photographic processing apparatus including recirculation of processing solution is provided with a variable loop additive control system comprising a treatment container in which additive solids, pastes or fluids are introduced and through which a controlled volume of processing solution is circulated from and back to the recirculating system loop. The secondary loop of the additive system allows control of the flow of processing solution through the treatment container so that the mixing of the additive into the processing solution may be controlled at a desired rate and the additive is not excessively utilized or dissipated. Various arrangements for connecting a secondary additive loop to the primary loop of a recirculating processing solution system are illustrated.

摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.
摘要:
A low volume photographic material processing apparatus, that utilizes a plurality of processing modules, that have a narrow horizontal processing channel. The processing modules may be arranged in either a horizontal or a vertical direction to solve the space constraints and the rigidity of prior photographic processor designs.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections.

摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced into opposite ends of alternating impingement slot nozzles, having delivery channels and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections. The slot nozzles and the pinch rollers work interactively to break down the chemical barrier layer.
