Method and apparatus for controlling an automatic silver recovery system for a photographic processor

摘要

A method and apparatus for controlling an electrolytic silver recovery system for a photographic processor, the control being effected in response to the surface area of the photosensitive material moved through the processing solutions. The apparatus determines the amount of silver deposited in the fixing bath of the processor from the width, length and density of the photosensitive material and used as an electrical signal for controlling the electrolytic current of the silver recovery system.
