Abstract

1436594 Photographic processing apparatus AGFA-GEVAERT AG 22 March 1973 [22 March 1972] 13847/73 Addition to 1289787 Heading G2X A photographic processing apparatus comprises a processing chamber (not shown) having a processing liquid inlet, pairs of feedrollers (not shown) for passing photographic material horizontally through the chamber, means comprising a tank 1 for collecting processing liquid leaving the processing chamber and connectable to a processing liquid circulating means for returning liquid from the collecting tank to the processing chamber, means for preventing the level of liquid in the tank from rising above a predetermined maximum level at which maximum level the lower feedroller of each pair is partially immersed in the liquid in the collecting tank so that liquid flows from the processing chamber to the collecting tank over the surfaces of these rollers with substantially no free fall of the liquid, and means in the collecting means for storing an additional volume of processing liquid which on operation of the circulating means is passed into the processing chamber to prevent liquid in the collecting tank from falling substantially below the predetermined maximum level. Specifically, the processing chamber used is that shown in Specification No. 1289787. The liquid in tank 1 is maintained at an operating level 9 by an edge 1b, excess liquid overflowing via channel 1c into an additional tank 8 having an air vent 1h and an overflow edge 1d (which may be the same height as or lower than edge 1b), any excess liquid draining into discharge If. In operation, pump 7 pumps liquid from tank I through outlet 1a to the processing chamber via riser pipes 2 and 3. This liquid flow causes water-jet pump 10 to pump liquid from tank 8 into the system via outlet 8a and inlet 10a thus maintaining level 9 in tank 1. The liquid consumed during processing is replenished through pipe 4. In a modification Fig. 2 (not shown), pump 10 is omitted and pump 7 used to pump liquid from both inlets 1a and 8a, outlet 1a being provided with a float valve (13), (14) to prevent a significant fall in the level in tank 1.
