Abstract

Abstract A multiprocess photographic processor has a plurality of tanks through which photosensitive material is transported. Different photosensitive materials are transported through different combinations of the tanks to provide different processing while utilizing the same processor. An automatic replenishment control system stores replenishment rates for each type of photosensitive material, as well as pattern information indicating those tanks which require replenishment during a particular process. During the processing of photosensitive material, replenishment is provided to selected tanks based upon the type of photosensitive material being processed, the stored replenishment rates, and the stored pattern information associated with the particular process being used.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 138 words
In a multiprocess processor of photosensitive material of the type having a plurality of tanks for containing processing fluid and in which different photosensitive materials are processed by one of a plurality of different processes by being transported through a unique combination of the tanks, an automatic replenisher contol system comprising: means for storing replenishment rates for the plurality of tanks; means for storing pattern information indicative of those tanks of the plurality which are in active use during each of the plurality of different processes; means for providing a signal indicative of the process in use; and means for automatically providing replenishment of processing fluids to tanks that are in active use based upon the stored replenishment rates, the signal indicative of the process being used, and the stored pattern information associated with the process being used.
Claim 2
Dependent Claim 138 words
In a multiprocess processor of photosensitive material of the type having a plurality of tanks for containing processing fluid and in which different photosensitive materials are processed by one of a plurality of different processes by being transported through a unique combination of the tanks, an automatic replenisher contol system comprising: means for storing replenishment rates for the plurality of tanks; means for storing pattern information indicative of those tanks of the plurality which are in active use during each of the plurality of different processes; means for providing a signal indicative of the process in use; and means for automatically providing replenishment of processing fluids to tanks that are in active use based upon the stored replenishment rates, the signal indicative of the process being used, and the stored pattern information associated with the process being used.
Claim 3
Dependent Claim 82 words
The invention of claim 1 wherein the means for storing replenishment rates stores, for each of the plurality of tanks, plurality of replenishment rates for use with different photosensitive material types; wherein the automatic replenisher control system further includes means for providing a signal indicative of the photosensitive material type being processed; and wherein the means for automatically providing replenishment selects the stored replenishment rates used in automatically providing replenishment based upon the signal indicative of the photosensitive material type being processed.
Claim 4
Dependent Claim 145 words
An automatic replenisher control system for controlling replenishment of processing fluids to a multiprocess processor of photosensitive material of the type having a plurality of tanks for containing processing fluids and in which different combinations of the tanks are used in conjunction with different processes, the automatic replenisher control system comprising: means for storing replenishment rates for the means for each of a plurality of different photosensitive material types; means for storing pattern information indicative of the tanks in active use in each of a plurality of different processes; means for providing a first signal indicative of one of the plurality photosensitive material types; means for providing a second signal indicative of one of the plurality of processes; and means for automatically controlling replenishment to selected tanks as a function of the stored replenishment rates, the stored pattern information, and the first and second signals.
Claim 5
Dependent Claim 145 words
An automatic replenisher control system for controlling replenishment of processing fluids to a multiprocess processor of photosensitive material of the type having a plurality of tanks for containing processing fluids and in which different combinations of the tanks are used in conjunction with different processes, the automatic replenisher control system comprising: means for storing replenishment rates for the means for each of a plurality of different photosensitive material types; means for storing pattern information indicative of the tanks in active use in each of a plurality of different processes; means for providing a first signal indicative of one of the plurality photosensitive material types; means for providing a second signal indicative of one of the plurality of processes; and means for automatically controlling replenishment to selected tanks as a function of the stored replenishment rates, the stored pattern information, and the first and second signals.
Claim 6
Dependent Claim 169 words
In a processor of photosensitive material having a tank for containing processing fluid for processing photosensitive material and having replenisher means for dispensing a predetermined volume of replenisher fluid to the tank periodically at a cycle rate, an automatic replenisher control means comprising: means for storing a plurality of replenishment rates for use with a plurality of different photosensitive material types; means for storing a value indicative of the predetermined volume; means for providing a signal indicative of transport speed of the photosensitive material through the tank; means for providing a signal indicative of the photosensitive material type being processed; means for automatically determining the cycle rate as a function of the stored predetermined volume, the signal indicative of transport speed, and the stored replenishment rate corresponding to the photosensitive material type indicated by the signal indicative of photosensitive material type; and means for automatically controlling operation of the replenisher means to cause the replenisher means to dispense the predetermined volume of replenisher fluid at the determined cycle rate.
Claim 7
Dependent Claim 169 words
In a processor of photosensitive material having a tank for containing processing fluid for processing photosensitive material and having replenisher means for dispensing a predetermined volume of replenisher fluid to the tank periodically at a cycle rate, an automatic replenisher control means comprising: means for storing a plurality of replenishment rates for use with a plurality of different photosensitive material types; means for storing a value indicative of the predetermined volume; means for providing a signal indicative of transport speed of the photosensitive material through the tank; means for providing a signal indicative of the photosensitive material type being processed; means for automatically determining the cycle rate as a function of the stored predetermined volume, the signal indicative of transport speed, and the stored replenishment rate corresponding to the photosensitive material type indicated by the signal indicative of photosensitive material type; and means for automatically controlling operation of the replenisher means to cause the replenisher means to dispense the predetermined volume of replenisher fluid at the determined cycle rate.
Claim 8
Dependent Claim 105 words
The invention of claim 4 and further comprising: means for storing an indication of whether the tank is active or inactive during each of a plurality of different processes; means for providing a signal indicative of the one process of the plurality which is in use; and wherein the means for automatically controlling the replenisher means causes the replenisher means to provide the predetermined volume of replenisher fluid at the cycle rate if the tank is indicated to be active during the process in use and inhibits operation of the replenisher means if the tank is indicated to be inactive during the process in use.
