ABSTRACT:
Materials such as photographic material is processed by supplying successive processing liquid baths to a processing receptacle. These baths are initially filled into a first series of receptacles and are simultaneously transferred to a second series of receptacles, one of which is the processing receptacle, by simultaneously tilting all the first receptacles. The second receptacles are then moved to a position in which their liquid contents are transferred back to the first receptacles, in each instance, one receptacle downstream from the receptacle from which the liquid was received by the second receptacles. The receptacles can take the form of cylindrical containers or tanks of a common body. The arrangement permits premeasuring the needed chemical liquids into the first receptacles and permits transferring the liquids one by one to the processing receptacle by simple movements of the body either in subdued light or in full light, where the processing receptacle is a light-tight compartment of the body.
