Patent DE-3135491-A1 (DE)
Title: Circuit arrangement for transmitting signals with low power dissipation by means of optocouplers
Inventor: CLAUSSEN CLAUS-JUERGEN ING GRA
IPC: H04B10/50
Filed: 1981-09-08
Abstract: The arrangement for transmitting an alternating-voltage signal with low power dissipation by means of an optocoupler is characterised in that the charge of a capacitor (5) which is charged up by the signal voltage is connected in the form of a short pulse of high current intensity to the light-emitting diode (11) of an optocoupler via a programmable unijunction transistor (10) which is fired at a specific capacitor voltage, as a result of which it is possible to achieve a very low power dissipation of the overall arrangement. <IMAGE>
Patent DE-3135879-A1 (DE)
Title: Device for the uniform and/or low-distortion inductive hardening of crank pins
Inventor: HALL HEINZ-LUDWIG DR
IPC: C21D9/30
Filed: 1981-09-10
Abstract: The invention relates to a device for the uniform and/or low-distortion inductive hardening of crank pins. In the hardening of crank pins right into the internally radiused part, there is the tendency for the cylindrical part to be heated to a considerably higher temperature than the said internally radiused part; in addition, a greater amount of heat flows into the adjoining crank webs at certain points on the circumference of the internally radiused part than at other points on its circumference so that, furthermore, the internally radiused parts become non-uniform in the circumferential direction. Both of these factors lead to distortion of the crankshaft. To compensate non-uniform heating and to obtain low-distortion hardening, separate simple and robust inductors of corresponding design are used respectively for the cylindrical part and the internally radiused part of the pin, these inductors being arranged offset on the circumference of the pin to be hardened. A separate controllable generator is provided for each of the various inductors, allowing the hardening of the cylindrical portion and of the radiused portion to be controlled separately, even in the circumferential direction.
Patent DE-3135991-A1 (DE)
Title: Punching or nibbling machine
Inventor: HERB EUGEN DIPL ING
IPC: B21D28/04
Filed: 1981-09-11
Abstract: In order to reliably guide the punch of a punching or nibbling machine during the working stroke on the one hand and create a stop for the work feed, in particular of a nibbling machine, on the other hand, a pin is mounted in the punch in such a way as to be displaceable in the axial direction of the punch. The pin (8) can be pressed into the interior of the punch against the resistance of a spring. In addition, it is possible, either via a machine plunger accommodating the punch or else via compressed-air feed under the pin, to lift the pin to such an extent that it clears the working space in the cutting area at least to such an extent that a workpiece, in particular a sheet-metal plate, can be displaced unimpeded therein and orientated. The lifting via the punch, however, is not effected via the normal drive of the punch but by means of an additional lifting device, because the plunger has to be lifted beyond its top dead centre. If an initial piercing operation is disregarded, the free end piece is held in a centring piece during the normal working strokes. The centring piece is located under the cutting area of the die. The pin is thus held virtually at both ends and it can consequently safely absorb the shocks during gradual work or machine feed and can readily absorb the cutting pressure. The free end piece can be of two-piece design, in which case one section then remains constantly in the centring piece.

Patent DE-3221553-A1 (DE)
Title: Compressed-air screwing tool
Inventor: STEIN DIETER
IPC: B25B23/145
Filed: 1982-06-08
Abstract: The compressed-air screwing tool has a control valve which regulates the supply of compressed air to the compressed-air motor and is located in a main compressed-air channel. After the compressed-air motor has been switched off, the control valve can be re-actuated by means of an actuating device. The latter has an operating part, which is a tappet of a valve, which controls the admission of compressed air from the main compressed-air channel to a subsidiary channel. From there the compressed air passes into a compressed-air chamber which is located on the side of the control valve facing away from the compressed-air supply. As a result, the control valve is opened via the compressed-air chamber when subjected to pressure, so that the screwing tool can work with an increasing torque. The actuating device can be actuated at the beginning or end of the screwing operation, so that it is possible to work with a higher torque at the beginning and then with a lower torque or vice versa, as desired.

Title: Method for the production of a sound absorbing filling for a silencer
Inventor: SEITZ WILFRIED
IPC: F01N13/18
Filed: 1982-10-19
Abstract: The invention relates to a method for the production of a sound absorbing filling of hardened mineral wool for motor vehicle silencers provided with irregular exhaust pipe internals. With such silencers, it is not possible, upon assembly, to push the exhaust pipe into a sound absorbing filling in the form of an integral shaped body. According to the invention, therefore, the mounting part (1) of the silencer itself has its interspaces filled with pads (8) of preimpregnated mineral wool, is then surrounded with an external shell (9, 10) corresponding to the silencer and is passed through a hardening furnace in order to harden the mineral wool. In this way, a sound absorbing filling integrated with the mounting part (1) of the silencer is obtained, and, upon assembly, this finished composite need only be pushed into the silencer casing. <IMAGE>

Patent DE-3311737-A1 (DE)
Title: Electronic switched-mode power supply
Inventor: BERGK GUENTHER
IPC: H02M3/156
Filed: 1983-03-31
Abstract: The subject-matter of the invention is an electronic switched-mode power supply for the regulated power supply of an electrical load and of an AC or DC voltage source at a different voltage level. The electronic switched-mode power supply contains a flyback converter which is pulsed in a primary manner and in which the primary winding of a transformer is connected in series with a controllable semiconductor switch, and whose secondary winding is connected in series with an electrical load and a diode. The current-flowing phase of the controllable semiconductor switch is determined by means of a second controllable semiconductor switch whose selection is determined via the voltage which is dropped on an emitter impedance which is connected in series with the switching path of the first controllable semiconductor switch. The emitter impedance is composed of a fixed impedance and a controllable impedance, whose impedance value is determined via a low-pass filter which is connected in the connection between the switching path of the first controllable semiconductor switch and the load. The resulting total emitter impedance is thus increased as the operating voltage rises, the peak current is reduced, and the secondary current is hence made linear.

Title: High-voltage power circuit breaker
Inventor: KOEPPL GEORG DIPL ING
IPC: H01H33/16
Filed: 1983-04-09
Abstract: A contact arrangement having a stationary (2) and a moving (1) switching piece has a contact part (6) which is under the influence of a first charged energy store (8) in the switched-on position and follows the moving switching piece (1) in the course of the switching-off movement, and which runs back again at least partially before the start of the switching-on movement. In the case of this contact arrangement, it is intended to vary the route of the following contact part (6) within wide limits. This is achieved in that a device for decoupling the first energy store in the course of the switching-off movement is provided between the first energy store (8) and the moving contact part (6), and in that the moving contact part (6), after the decoupling of the first energy store (8) from a charged-up second energy store (10), follows the moving switching piece (1) and is then moved back by means of a charged-up third energy store (12). Such a contact arrangement can be used as an auxiliary switching point of a high-voltage power circuit breaker for switching a common resistor for switching on and off. <IMAGE>
