Abstract (en)
[origin: US5093678A] A processor for photosensitive material provides a processing solution to a processing chamber while the photosensitive material is advanced through the chamber. The processing solution is drained from the chamber and passes through a chute as it is returned to a sump for recirculation to the processing chamber. A laminar fluid flow wick located in the chute avoids air entrapment that would be caused by fluid freely flowing through the chute.
