Title: Device for engaging and disengaging the printing unit cylinders
Inventor: JENTZSCH ARNDT DIPL ING
IPC: B41F13/40
Filed: 1989-02-14
Abstract: The invention relates to a device for engaging and disengaging the printing unit cylinders in offset printing machines, in which the printing unit cylinders are mounted in eccentric bushes which are rotated for the purpose of engaging and disengaging the printing unit cylinders by means of hydraulic operating cylinders on both sides of the machine. The object of the invention, reliably to guarantee the synchronisation of the engagement and disengagement movements of the impression cylinders on both sides of the machine, is achieved according to the invention in that a control valve and a compensating circuit containing a line are assigned to a series circuit which connects, by means of lines, the operating cylinders which can be moved against fixed stops. Furthermore, the control valves are non-return valves and the control valve is an OR valve. In this case, the operating cylinders have the same volume.

Patent DE-3907830-A1 (DE)
IPC: B02C4/28
Filed: 1989-03-10
Abstract: The invention relates to a material bed roller mill for crushing brittle material to be ground in the gap between two driven rollers which are pressed against one another with a high grinding force with a filling shaft for the delivery of material provided above the rollers. The width of the stream of material delivered to the roller gap can be altered with the aid of vertical guide walls which are adjustable at right angles to the vertical central plane of the roller mill while maintaining their vertical position. The column of material which is aligned vertically above the rollers creates pressure which is introduced fully into the material bed crushing and if required the column of material can be moved in the cross direction with respect to the rollers.

Patent DE-3914831-A1 (DE)
Inventor: HAEFFNER BERND
IPC: B41F31/04
Filed: 1989-05-05
Abstract: In order to adjust the ink metering device of a printing press to a zero ink application position at any time, the control (6, 7, 8) of the ink metering device is extended by a control device (9) and the position indicators (5) of the ink metering elements (1) are constructed as sensors (13). The control device (9) switches on the adjusting drives (2) of the ink metering elements (1) in the direction of the inking roller (3), determines whether the measurement signals of the position indicators (5) change with time and switches off those adjusting drives (2) of the ink metering elements (1) whose positions no longer change with time since the ink metering elements (1) are resting on the inking roller (3). These zero positions of the individual ink metering elements (1) can be stored in the control (6, 7, 8) for the further adjusting operations.   <IMAGE>
