Abstract: An integratable circuit configuration includes an analog signal network being subject to fluctuations in a given way. A switched capacitor network is connected in series with the analog signal network and receives settable coefficients. An analog comparison network which is subject to the fluctuations in the given way, receives an excitation signal and supplies a response signal in response to the excitation signal. An evaluation circuit is connected to the analog comparison network and to the switched capacitor network for comparing the response signal with a reference signal and setting the coefficients of the switched capacitor network as a function of the comparison.

Abstract: In a washing device for an impression cylinder of a printing machine, there is provided a washing roller capable of being brought into contact with and liftable away from a cylindrical jacket surface of the impression cylinder in vicinity of a gripper bridge of the impression cylinder, and being sprayable with cleaning solution, the washing roller comprising a washing brush extending over substantially the entire length of the impression cylinder and being separately driven, the washing roller being rotatable in a direction opposite the direction of rotation of the impression cylinder and being rotatable at a higher speed than the rotating speed of the impression cylinder, the washing roller being movable automatically into its contact with the impression cylinder.
