Title: Method for active compensation control of any number of cylinders operated in parallel in order to achieve synchronous movements
Inventor: FREYMANN RAYMOND DR
IPC: G05D3/14
Filed: 1984-08-17
Abstract: A method for controlling any number of cylinders operated in parallel in order to achieve synchronous movements envisages that a desired value w be fed to each cylinder via a control circuit with a transfer function Gi and a feedback Hi. One of the control circuits is used as a master circuit. To control the cylinders relative to one another, the difference between the actual value of the master circuit and the actual value of the respective other control circuit is fed back and fed to the input of the respective other control circuit together with the desired value. <IMAGE>
Patent DE-3434008-A1 (DE)
Title: Friction-lining fastening
Inventor: WIGGEN PETER DIPL ING
IPC: F16D13/64
Filed: 1984-09-15
Abstract: The invention relates to the fastening of the friction rings of a clutch disc, each friction ring being connected firmly to a carrier plate on the side facing the opposite friction ring. Arranged between the two carrier plates are two spring segments, each with their corrugation troughs resting against one another, and, with their corrugation peaks, which extend in both circumferential directions, they form convex spring areas. Arranged in the area of each of these corrugation peaks are rivets which are constructed alternately in such a way that, on one side, they each connect a carrier plate to a spring segment and, on the opposite side, engage behind the other carrier plate with a rivet head in order in this way to ensure the spring prestress in the axial direction for the springing of the linings. The arrangement of the carrier plates which are connected in a fixed manner to the friction rings ensures considerably higher insensitivity to circumferential waviness at high temperatures. At the same time, torsional strength is increased and the possibility of matching the spring characteristic and the spring prestress is to a large extent retained.

Patent DE-3441390-A1 (DE)
Inventor: KLEEBLATT HERBERT DIPL ING
IPC: F02D41/14
Filed: 1984-11-13
Abstract: In an automatic control method for reduction in the level of contaminants emitted by a gas engine, the automatic control process is orientated in accordance with the reference point at which lambda is equal to unity and enriches the mixture after detecting this point by a certain step. Subsequently the instantaneous probe potential is measured and used by an automatic control circuit as a set point, which so affects the actuator for setting the air ratio that the probe potential is kept constant at this set point. The automatic control system in keeping with the invention reacts immediately in response to a disturbance and does not have to wait until a renewed search for the reference point takes place.

Title: Device for grinding semi-finished products
Inventor: EVERTZ EGON
IPC: B24B27/033
Filed: 1985-10-21
Abstract: The invention relates to a device for grinding semi-finished products made of steel, the problem being to avoid excessive material removal in the edge region, whilst the semi-finished product is rotated about its longitudinal axis and advanced on its longitudinal axis. Known devices allow for a relatively long dwell time of the edge region under the grinding wheel by pressure relief, it being necessary to provide the varying pressure during rotation of the semi-finished product in full by means of forces acting on the grinding-wheel bearing. In contrast, the invention achieves a pressure relief in the edge region of the semi-finished product by adjusting the edge regions during rotation to a lower height position than the central regions. This is achieved by supporting the semi-finished product on mutually opposite, loosely rotating rollers, the mutual distance of which is smaller than the distance corresponding to the thickness of the semi-finished product. In an arrangement of this type, the central regions of the semi-finished product are highest and the edge regions lowest if, in addition, the semi-finished product is driven in rotation.

Title: Process and system for producing plastic bag stacks from a doubled plastic film web
Inventor: BUSCHMANN HANS ALBERT
IPC: B31B19/98
Filed: 1986-03-13
Abstract: Process for producing plastic bag stacks from a doubled plastic film web, the plastic film web being guided intermittently through a welding an severing station in which the double-bag sections are severed off from the plastic film web. Directly downstream of the welding and severing station, the double-bag sections are transferred one after the other, with the aid of pivoting transfer elements, to a pin-type stack conveyor and stacked in their central region on the pin-type stack conveyor to form a stack comprising a predetermined number of double-bag sections. The complete stacks are conveyed away with the aid of the pin-type conveyor and during or after this are separated in their central region into two individual bag stacks. The double-bag sections are grasped at their wall regions on both sides by the transfer elements and moved downwards by means of these wall regions and, in the process, stacked on the pin-type stack conveyor, which is guided as far as the welding and severing station. The wall regions of the double-bag sections are then released and the transfer elements are moved back to their initial position by means of a pivot movement about horizontal pivot axes extending in the conveying direction of the pin-type stack conveyor. A system for carrying out the process is also specified. <IMAGE>

IPC: G03D3/06
Filed: 1986-08-30
Abstract: The device (1) comprises a diaphragm (7) which is actuated by a motor and covers an exposure test wedge (5) after the application of a permanently prescribed quantity of light through the exposure test wedge (5) onto a printing plate (3) which is to be developed. Sensors (9) and (22) are present, which measure the incident exposure level of a light source. The individual sensor is respectively assigned to a specific type of printing plate, e.g. positive or negative plates, and switched on when this corresponding type of printing plate is to be developed. The input signal of the sensor (9) or (22) is fed to a control unit (24) which comprises an amplifier (25), an integration circuit (26) and a comparator (27) all connected in series. The sensor input signal, amplified by the amplifier (25), is multiplied in the integration circuit by the exposure time t, fed to the comparator and compared with a permanently prescribed value J . t = constant. The constant value is fixed in accordance with the printing plate to be developed. The output of the comparator is connected to a starting and self-holding device (14) for the motor (12) which actuates the diaphragm (7). If the comparator (27) delivers an output signal, the motor (12) closes the diaphragm (7). A control lug of the starting and self-holding device (14) then shuts down the motor (12) and stops the closing movement of the diaphragm (7). <IMAGE>
