摘要:
A device designed to compensate the level of chemical treatment baths automatically, applicable in particular to film developing machines, comprises a vessel (90) containing a supply of water which is directed by means of a pump (50) and a relative pipeline (51) through a manifold (7) and toward the baths (11, 12, 13, 14, 15) by way of relative feed pipelines (71, 72, 73, 74, 75), each controlled by a relative solenoid valve (61, 62, 63, 64, 65) piloted to operate simultaneously with the pump (50) by way of an electronic control unit (41) in receipt of signals relayed from sensors (21, 22, 23, 24, 25) designed to detect a drop in the level of the solutions in the relative baths (11, 12, 13, 14, 15). The feed outlets of the pipelines (71, 72, 73, 74, 75) discharge above the level of the relative bath (11, 12, 13, 14, 15) so as to prevent any possibility of reflux, whilst in the case of the pipeline (75) serving the final bath (15), water is supplied by way of a tubular element (81) with holes (85) strategically placed to generating jets directed onto at least one roller (321) of a set of paired squeeze rollers (32).

摘要:
The invention is directed to a device for processing photographic material, said device comprising at least one low volume processing and transport channel which does not include any transport means, wherein the level of the transport liquid is held within the boarders of the processing and transport channel. Furthermore, the invention is directed to a processing vessel for processing photographic material, said vessel comprising a low volume processing and transport channel which does not contain any transport means, wherein the level of the processing liquid is held within the borders of the processing and transport channel.
