Weighing device for the point-of-sale of a retail outlet

A washing unit for an offset duplicating machine, with the washing unit including a washing tank for accommodating a cleaning fluid and a washing roller arranged in the washing tank in such a manner so that at least a portion thereof is dipped in the cleaning fluid accommodated in the washing tank. The washing tank is connected to a circulatory system for recirculating the cleaning fluid. The circulatory system includes a pump for pumping the cleaning fluid through the circulatory system and a filter for filtering the cleaning fluid while the cleaning fluid is being recirculated in the circulatory system.

Washing unit for an offset duplicating machine

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.

An apparatus for a metered feeding of ink to a ductor roll of an offset printing device. The ductor roll is adapted to be dipped into an ink pool which is connected to a device for supplying metered amounts of ink. The device for supplying the metered amounts of ink is controlled by an installation for monitoring a level of ink in the ink pool. The monitoring installation includes a distance sensor which is constructed as a capacitive proximity switch.

A device for controlling and monitoring the level of a washing liquid in a washing unit of a printing machine which includes a wash tank having a washing liquid therein and a pickup roller mounted in the tank and rotatable in the washing liquid to lift the liquid on the surface of the roller and transfer it to a rubber blanket roller to be cleaned, comprises a control tank which is connected to the wash tank and arranged at substantially the same level as the control tank. A supply tank for the washing liquid is located above the control tank and supplies liquid into the control tank under the regulation of an electromagnetically controlled valve. The valve is switched in order to provide for flow from the supply tank into the control tank in accordance with the level in the control tank. The level of the control tank therefore maintains a level in the wash tank by virtue of the flow between the control tank to the wash tank. In order that the control can be effected precisely, the control tank is provided with a partition wall having a control size opening therethrough below water level so that water which is delivered from the supply tank into one side of the partition wall will flow to an opposite control side only gradually so as to regulate a float valve which is connected in a circuit to operate the control valve from the supply tank to the control tank.
