Abstract
An electrically operated device such as a duplicating machine has a recptacle for accommodating a fluid for the chemical treatment of sheet material and like objects. The receptacle may be in the form of a dip tank designed for passing sheet material therethrough. This dip tank is connected via a supply conduit to a storage tank and the supply conduit includes a pump controlled by an automatic charging and metering unit for supplying fluid to the dip tank. A drain conduit leading to the storage tank is connected to the dip tank. This drain conduit includes a solenoid valve for stopping or allowing the flow of fluid through the drain conduit.
