Title: Control method for operating pneumatic brake servo - has solenoid opening and closing the control valve in controlled sequence to minimise noise and vibration.
Inventor: ECKERT ALFRED
IPC: B60T13/72
Filed: 1995-08-10
Abstract: The pneumatic servo has a solenoid valve which opens a first valve to the working chamber and a second valve to connect the two chambers. To minimise the noise and vibration of the servo the first valve is opened at an initial low rate (T01 - T11) followed by a rapid opening (T21 -T31) and terminated by a reduced rate (T31 - T41) to the end setting of the valve. This is achieved by a programmed control of the solenoid. The valve connecting the two chambers of the servo has a similar control. An initial fast drive of the solenoid sets the valve to the start of the opening sequence and is followed by a similar program as for the fist valve. The closing sequence of the valves has another programmed sequence to similarly minimise noise and vibration.

Title: Yarn reel winder compensating for contact roller moulding inaccuracies
Inventor: BREMER CARL-HERMANN
IPC: B65H67/048
Filed: 1996-08-14
Abstract: A machine for winding a continually running thread (19) has a mounted rotating spindle for winding the thread on a reel (17). A rotating contact roller (1), supported by a carrier (3) bearing (2), lies on the reel surface (18) with a preset force which can be adjusted by a controllable actuator (4). The bearing is made to be elastic and a sensor (5) on the carrier or the contact roller is so arranged that it detects relative movement in the bearing between contact roller and carrier. The actuator is under control of a controller (6) to which the sensor is connected, in such a way that a desired applied force profile for the roller is achieved.  Also claimed is a process for regulation of the applied force where: (a) the relative movement between bearing and applied roller is detected; (b) a signal corresp. to this movement is sent to the controller; an actual bearing position derived from the relative movement is compared with a preset value in the controller and; (c) the actuator is adjusted via the controller to follow the desired force profile.  Pref. the sensor is a displacement transducer, i.e. the distance between the opening of a nozzle directing an air stream against a reaction plate and the plate and the resulting varying air pressure is taken as a measure of the application force. Alternatively the sensor is a set of strain gauge foils fixed to the contact roller. The actuator is a piston-cylinder unit which is adjusted by the controller via the control valve (7). Alternatively the unit is adjusted via a pair of two-way valves. An alternative sensor is a transducer which detects the pressure in the unit cylinder and this pressure serves as a measure of the applied force. The controller drives the actuator when a preset acceptable deviation between applied force desired and actual values is exceeded so that either a pressure or a pull is exerted on the contact roller carrier. A control circuit comprising the sensor, the controller and the actuator is calibrated when the contact roller is lifted off.

Inventor: EHRHARDT ROLF DIPL ING
IPC: G06Q10/00
Filed: 1996-08-28
Abstract: For a reel cutter, particularly in the paper industry, optimal cutting planes are determined using mathematical methods. This is done by breaking the process down into individual steps, where, first, a continuous solution of the linear optimization problem is found using a known multiplication method. Then, variables are sought and defined with regard to their limits. By defining a so-called "search tree", successive steps can be taken and these process steps repeated until the variables are whole numbers. An acccessory device comprises a programmable digital computer consisting of the usual components which is programmed according to the stated process and thus defines suitable means for operation of the reel cutter (100).
