  • Automatic variable-quantity/fixed-time anti-oxidation replenisher control system
    Patent number: 4372665
    Abstract: A processor of photosensitive material includes an automatic control system for providing anti-oxidation replenishment and preventing anti-oxidation overreplenishment, as a function of a stored anti-oxidation replenishment rate and anti-oxidation replenishment provided by exhaustion replenishment. A fixed time interval is initiated after which the anti-oxidation replenishment required due to expired time is compared to the amount of anti-oxidation replenishment provided by the exhaustion replenishment in that time interval. An amount of needed anti-oxidation replenishment is added to the developer tank, as a function of the difference by which the required anti-oxidation replenishment exceeds the anti-oxidation provided by exhaustion replenishment.

    Patent number: 4372666
    Abstract: A processor of photosensitive material includes an automatic control system for providing anti-oxidation replenishment and preventing anti-oxidation overreplenishment, as a function of a stored anti-oxidation replenishment rate and anti-oxidation replenishment provided by exhaustion replenishment. A time interval of a predetermined duration is initiated by the control system. During the interval, the control system provides exhaustion replenishment based upon the area and density of photosensitive material processed. At the end of the interval, the control system compares the anti-oxidation replenishment required due to expired time to the amount of anti-oxidation replenishment provided by the exhaustion replenishment during that time interval. The control system then causes the needed amount of anti-oxidation replenishment to be added to the developer tank.
