Title: Method and position controller for the adaptive position control of an electromechanical drive affected by friction
Inventor: BITZER RAINER
IPC: F02B3/06
Filed: 1987-09-23
Abstract: In a method and an adaptive position controller for the control of an electromechanical drive affected by friction, which is especially suitable for the digital adaptive position control of the quantity-determining element (control rod) of an electric diesel injection pump, it is proposed to arrange, in parallel with the state controller with preferably PIDD<2> characteristic, a pre-control characteristic which contains upwards and downwards characteristic curves which correspond to the friction hysteresis of the path. The control variable is fed to the pre-control characteristic and the control deviation is fed to the state controller in the bypass, there being obtained from the combination of the two position signal components generated in this way from the pre-controller and the controller a position output value which ensures rapid and highly accurate positioning of the electromechanical drive. In this case, the characteristic curves in the positioning pre-control characteristic are matched on-line to the varying parameters of the path. <IMAGE>

Title: Unit for the bleeding of motor vehicle hydraulic brakes and hydraulic clutches
Inventor: TROBITZSCH AXEL
IPC: B60T11/30
Filed: 1988-04-22
Abstract: In the case of my invention for the bleeding of motor vehicle brakes and clutches the 2nd person hitherto needed at the bleeding nipple is no longer required, the handling is simple and the purchase costs of the unit are very low. In addition the unit is very small. The 4mm hose is pushed on to the bleeding nipple and the latter opened. By operating the brake pedal the fluid mixed with air (drawing) A enters the valve. At point B the valve rubber widens and at point C runs through the 6mm hose into a collecting flask. When the pedal is released, the valve rubber automatically shuts off point B again, so that the fluid stops and no longer flows back. This is generally repeated 4 to 5 times until no more air bubbles remain in the 4mm hose. The bleeding nipple is then closed and the brake line is bled. <IMAGE>

Title: Washing device
Inventor: SPORER ROBERT
IPC: B08B3/02
Filed: 1988-06-22
Abstract: In workshops such as for example motor vehicle workshops, heated high-pressure cleaners are as a rule present which have a heat exchanger and a high-pressure pump which is connected via a hose to a spray gun, by means of which a water jet can be directed onto an article to be cleaned. For cleaning small parts, such a high-pressure cleaner is not suitable. To this end, a washing device (1) is proposed, which can be connected to a conventional high-pressure cleaner. The washing device (1) contains a closable housing (2), in which a washing basket (7), which receives the articles to be cleaned, is arranged rotatably. Arranged in the interior of the housing are high-pressure nozzles (21) which are connected to the high-pressure cleaner and are directed onto the washing basket (7). The washing device (1) can be manufactured relatively inexpensively and is most suitable for rapid and convenient cleaning of small parts such as machine parts or the like (Fig. 1). <IMAGE>

Title: Cutting drum connected in a rotationally locked manner to the output shaft butt of a reduction gear unit
Inventor: HENRICH FRIEDHELM
IPC: E21C31/02
Filed: 1988-10-14
Abstract: Known cutting drums are rotatably supported only in the supporting-arm area on the reduction gear unit lying in the interior of the drum body and fastened to the machine body or to the supporting arm of a shearer loader. Consequently, the output shaft butt of the reduction gear unit, on the working-face side, apart from having to absorb the drive torque, must absorb a not inconsiderable portion of the drum weight, the winch tensile forces and the shock-like loads occurring during shearing operation. The aim of proposed solution is to design the cutting-drum bearing arrangement in such a way that, except for the torque, it receives all forces acting on the cutting drum. To this end, it is proposed to fit the rotationally symmetric peripheral surface of the reduction gear unit (4) located in the cutting-drum body with two rolling-contact bearings (14, 15) carrying the cutting drum (2). The rolling-contact bearings (14, 15) lie inside a bush (17) centring and carrying the cutting drum (2). On the machine side, the radial gap (33) between the bush (17) and the goaf-side gear cap (30) is closed off by a diaphragm-like seal (25) held by the reduction gear unit (4). On the working-face side, sealing is obtained by the end wall (10) of the drum body (3) or of a cap (6). The end wall (10) extends up to the reduction gear unit (4) and is connected to its output shaft (5) in a rotationally locked manner. <IMAGE>

Title: Method for positioning tools of a longitudinal cutting and/or corrugating machine and device for implementing the said method
Inventor: SCHNABEL KLAUS DIPL ING
IPC: B26D7/26
Filed: 1988-10-26
Abstract: In the case of the method for positioning tools of a longitudinal cutting and/or corrugating machine, especially for webs of corrugated cardboard, a plurality of driveable, displaceable tools which are situated on opposite sides of the web and interact in pairs are made to adopt predetermined positions by means of an adjusting spindle which is assigned to the upper and lower row of tools. The tools of each row of tools are in contact with one another before positioning commences. When in position, they are held in such a way as to prevent involuntary displacement. Each batch of tools is carried along concomitantly by controllable sliding/fixing stops during displacement of the adjusting spindle. As the adjusting spindle is withdrawn, the batch of tools is withdrawn together with it, the tool which has reached its desired position being released and fixed in the desired position. <IMAGE>
Patent DE-3836878-A1 (DE)
Title: Safety shut-off valve
Inventor: GOTTFRIED JOSEF
IPC: G05D16/06
Filed: 1988-10-29
Abstract: A safety shut-off valve serves to monitor an output pressure downstream of a gas-pressure regulator. An actuating-diaphragm device is acted upon by this output pressure and triggers a closing operation if this output pressure is exceeded by a certain value. There are also cases where this safety shut-off valve is required to provide a safeguard against an excessive regulator input pressure or, in the case of a pressure regulator with an adjustable output pressure, over a relatively large range, the safety shut-off valve is required to follow with a sliding triggering pressure. In the case of a fault and the triggering of the safety shut-off valve by excess pressure or with a gas feed from a liquified gas container stopping when the latter is empty, this safety shut-off valve is also required to be able to perform a pressure-controlled emergency feed from a replacement liquified gas container. These requirements are met, in the case of input-pressure monitoring, by the arrangement of a safety valve between the output of the safety shut-off valve and the actuating diaphragm device and, for sliding output-pressure monitoring, by connecting the upper pressure-regulator diaphragm space with a safety valve in the diaphragm to the lower space of the actuating-diaphragm device of the safety shut-off valve and the arrangement of a ventilation metering facility in this pulse connection line. A connection valve with a positively opened closing valve arranged at the input connection of the safety shut-off valve allows ... Original abstract incomplete.

Patent DE-3841864-A1 (DE)
Title: Doppler radar
Inventor: MINKER MANFRED DIPL ING
IPC: G01S13/524
Filed: 1988-12-13
Abstract: In the case of a Doppler radar having echo signals which are present in complex form in an I channel and a Q channel, a defined relative speed can be compensated for or simulated by presetting a value for a relative speed on the basis of its magnitude and, in the case of a pivoted antenna polar diagram, possibly in terms of direction as well, in that a clock generator produces a clock signal whose clock frequency is proportional to the predetermined relative speed and, in the case of an agile transmission frequency, to the product of the relative speed and the transmission frequency. An address counter which is incremented by the clock signal addresses two memories having sine and cosine function tables respectively. The echo signals are multiplied in a computation circuit in complex form by the sine and cosine values which have been read from the table. The output signals resulting from this exhibit a defined Doppler frequency shift from the input signals, which frequency shift is governed by the predetermined relative speed.
