Title: Arrangement for controlling relatively high power switching-off thyristors
Inventor: MUES MICHAEL DIPL ING
IPC: H03K17/723
Filed: 1984-05-17
Abstract: It is intended to create an arrangement for controlling switching-off thyristors, which arrangement operates reliably with a simple construction and manages with cheap components. It is intended to make possible simple connection as a passive component and at the same time to satisfy the requirement for potential isolation between the control section and power section. For an arrangement for controlling relatively high-power switching-off thyristors, using converters with downstream-connected rectification means, it is proposed according to the invention that four separate individual converters be used for the transmission of the turn-on and turn-off pulses and for generating the continuous gate current and negative bias voltage, and that the switching-off thyristor be controlled exclusively via these individual converters, with complete potential isolation between the power section and control section, two of the individual converters being continuously driven in a synchronously parallel manner, connected in parallel on the primary side, in order to transmit the turn-on pulse, and being driven in a phase-shifted parallel manner, by means of a square-wave voltage, in order to generate the continuous gate current. <IMAGE>

Patent DE-3443672-A1 (DE)
Title: Jet suction pump for evacuating and suction removal of aggressive media, with water jet pumps, without using pressurised water
Inventor: LANGER ALFRED
IPC: F04F5/06
Filed: 1984-11-30
Abstract: To generate a vacuum or for suction removal of aggressive media and gases with water jet pumps, without using pressurised water and without seals being required for rotating parts in the suction region, a jet suction pump is used. The injector effect of the water jet pumps is generated by a reduced pressure which, through an upstream free-running impeller, draws the working fluid, which is water, through the nozzles of the water jet pumps. The water jet pumps do not have any water feed lines because they themselves are positioned in the water. By virtue of the circulation system via the impeller, the water consumption is reduced towards "zero" or to a minimum. The jet suction pump, when aggressive media are used, preferably consists of plastics which also withstand thermal stresses, because all pump components are in the water and are cooled by a small inflow of tap water. As a result of the suction jet arising from the nozzles, any blowback of the medium drawn in in the water jet pump is prevented, by virtue of which effective suction performance is achieved even at an elevated water temperature.

Title: Mounting device for at least two parts which are to be connected to one another, preferably on motor vehicles
Inventor: FANZOTT GERHARD ING GRAD
IPC: F16B5/02
Filed: 1985-02-22
Abstract: The mounting device is provided for two parts which are to be connected to one another, of which the one part has a receptacle, which is bounded by a wall, for a mounting part. Said mounting part is provided with a deformation section for an elastically deformable wall part of the receptacle, which wall part lies in the movement path of the deformation section during insertion of the mounting part into the receptacle and engages behind the one part in the elastically deformed position. Since the wall part of the receptacle is elastically deformable, the mounting part can be pre-installed even before installation into the receptacle, so that the wall part is not yet elastically deformed. In consequence, the two parts which are to be connected to one another can be brought into their installation position without difficulties.

IPC: B65H54/38
Filed: 1985-06-13
Abstract: The invention relates to a winding machine for random winding. Level stages of the first and also higher order are jumped by changing the traversing frequency before the critical level-stage range is reached. Three different frequencies are available for this. The amount of the frequency jump for jumping the level stages in relation to the normal frequency amounts to more than 0.02 for the level stages of the first order and to less than 0.01 for the level stages of the higher order. It is possible to jump only those level stages at which the amount of the selected frequency jump and the distance from the next level stages to be jumped are so great that their critical ranges are not affected thereby.

Title: Filling apparatus for bags receiving granular loose material, with a conveyor band for transporting them away.
IPC: B65B61/24
Filed: 1985-07-24
Abstract: In the apparatus, bags are filled upright with granular loose material, for example plaster mixtures or mortar mixtures, and then, after being filled, are thrown off onto a conveyor band which receives the bags horizontally. The conveyor band brings the bags to a collection station, where they are collected by the robot. The filled and closed bags still contain residual air. Moreover, they are pear-shaped, since the filling mass accumulates especially on the bottom of the bag. Because the conveyor band runs over cylindrical rollers, on which square strips (24a) are welded, it executes a continuous vibrating movement, the result of which is that the loose material in the bags is distributed uniformly and the bags assume the form of a flat package. The residual air can also be eliminated by means of pressure rollers (34, 35) which run under pressure over the flat bags. <IMAGE>
