Abstract: 1404415 Automatic electric control LOGETRONICS Inc 25 Sept 1973 [25 Sept 1972] 44966/73 Heading G3N A film processing apparatus comprises a control means responsive to the counting of a predetermined number of pulses, representative of transport of photo-sensitive material along a treatment path, for controlling a state of operation of a material treatment station. As shown, the movement of a conveyor of a film-processor is sensed by a photo-electric arrangement 1a, 1b co-operating with a slotted disc 1c driven by a main drive-shaft 1d. The pulses from the photo-cell are squared 2, differentiated and clipped 3, and trigger a pulse-generator 4. The passage of a film to the input of the conveyor actuates a switch 6. It is stated that the mechanical switch can be replaced by an ultrasonic, pneumatic, or infrared sensor. The pulses from generator 4 are applied through noise-level eliminating gates 5, 12 to a fast integrator 13 and a slow integrator 7. During the passage of a film a feedback capacitor 7b, 13b of each integrator is short-circuited by a contact of the switch 6 so that the level sensed by voltage level detectors 8, 14 through drivers 9, 15 actuate a really 10 and energize a lamp 16. The actuation of relay 10 energizes, through contacts 10d, 10c controlled circuits for film-processing. The switch 6 is opened when the trailing edge of the film passes it and the integrators begin to count pulses. At a first count, integrator 13 causes the lamp 16 to be extinguished to indicate that a fresh film may be inserted. At a second count, representing total travel of a film through the processor, the integrator 7 causes the relay 10 to be de-energized and the processor put into stand-by condition.
