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.

Abstract: An automatic replenisher control system for a photographic cine processor includes a film type sensor which identifies, by film type, the unprocessed film entering the processor. Replenishment of processor fluids is controlled as a function of the identified film type. The film type sensor includes an array of reflective infrared (IR) sensors which are positioned across a path of the film. Each infrared sensor provides a sensor signal indicative of whether the film is adjacent the infrared sensor. Signal processing circuitry, including a digital computer, first determines the width of the film by sampling the signals from the infrared sensors a series of times, and totalling the number of sensor signals indicating the film is adjacent the sensor. 110 format film and large format films (such as 46 mm, 120/220 and 70 mm format films), are identified solely on the basis of width. A perforation sensing routine is performed to distinguish between leader, 126 format film and 135 format film.
