Abstract
Abstract A device for replenisher control suitable for use in automatic web transporting equipment including X-ray and other film developing apparatus. The device includes a pair of rollers which are driven by the web as it passes through the apparatus. One roller is provided with a shaft extension upon which a driving gear is mounted. A large gear which incorporates a switch attracting magnet is responsive to the driving gear and rotates when the web rotates the rollers. The switch attracting magnet functions a timer which precisely controls the operation of a replensiher pump or other apparatus. In the case of film developing apparatus, a replenisher pump is operated through a timed cycle to add additional solutions in proportion to the rate of depletion of the developers and fixers utilized in the film development. The device also includes a signal gear which is responsive to the large gear to actuate a signal circuit for visual indication that a web is passing through the device.
