ABSTRACT:
In film processing apparatus provided with (a) a tank into which a processing liquid is pumped; (b) a pair of oppositely spaced film process channels in the tank; (c) a plurality of liquid ingress openings to the channels for directing a processing liquid pumped into the tank to flow into the channels against the emulsion side of a filmstrip advanced along the channels; and (d) a plurality of liquid egress openings from the channels for enabling the processing liquid flowing against the emulsion side of the filmstrip to flow around the longitudinal edges of the filmstrip and out of the channels into the tank, an improvement is added comprising a processing liquid distribution box. The distribution box is disposed in the tank between the film process channels to receive a processing liquid pumped into the tank, and it includes respective series of staggered relatively small orifices positioned to discharge the processing liquid in a jet-like manner from the box interior into the liquid ingress openings to the film process channels. The orifices effect an improved agitation of the processing liquid adjacent the emulsion side of a filmstrip in the channels.
