Title: Automatic replenishment method and apparatus for photographic processes
IPC: G03D3/06
Filed: 1975-04-21
Abstract: 1488193 Photographic processing MEAD CORP 21 April 1975 [22 April 1974] 16445/75 Heading G2X In a method of automatically replenishing chemical processing baths in film processing apparatus, the baths being of two types, one type consisting of materials which are consumed according to how much imagery is being processed, and the other consisting of materials which are consumed according to the amount of film being transported, the method comprises the extraction and analysis of one sample of each type, determining the replenishment necessary, and supplying said replenishment to all the baths of that particular type. Image-dependent solutions include developer and bleach baths, as shown contained in respective tanks 11 and 14, and bulk-dependent solutions include stop, hardener, and fix baths, as shown contained in respective tanks 12, 13, 15. The film 10 passes through all these baths in turn, in the direction shown. The chemical concentration of only one bath of each type is monitored, e.g. baths 14 and 15. A portion of the solution in tank 14 is continuously circulated through a closed loop system 31 by a pump 35, which loop system includes a process controller 37. This continuously samples and analyses the bromine concentration in the bleach solution by a linear null-point potentiometric method. When this falls below a standard reference level, a signal is generated which is transmitted to a valve 45 controlling flow of replenishing solution from a tank 24 to tank 14. At the same time the signal is also transmitted to another valve 21 controlling flow of developer solution from a replenishing tank 21 to tank 11. Thus the monitoring of the bleach solution in tank 14 controls replenishment of both image-dependent baths 11 and 14. Similarly replenishment supplies to all three bulk-dependent solutions in baths 12, 13, 15 are controlled by monitoring the concentration in one of them, in this case the silver concentration in the fix tank 15. Since the chemicals in the different tanks are not all consumed at the same rate, this differential may be pre-set into the various control valves 45, 44, 54, 55, 56.
