Title: Self-regulating triggering pulse formation for an invertor having a common suppression circuit
Inventor: LAUTZ HARALD ING GRAD
IPC: H02M7/515
Filed: 1983-01-27
Abstract: In order to reduce the reverse voltage load on suppression thyristors in the common suppression circuit of an invertor, the driving invertor voltage is passed in a defined manner during the suppression phase, irrespective of the load. This is done by detecting the current-flow duration through the suppression thyristors (V1, V2) via AND elements (U1, U2) operating as gating stages. The output signal (RV2) of the one AND element (U2) causes triggering of the main thyristors (V6 to V11) of the invertor, via a memory, during the hold-off time of the one suppression thyristor (V2). The output signal (RV1) of the other AND element (U1) releases the drive of the main thyristors (V6 to V11) after the end of the suppression process, by means of resetting a monostable timer. <IMAGE>

Title: Hacksaw
Inventor: WILBS ALFRED
IPC: B23D51/02
Filed: 1983-02-04
Abstract: A hacksaw (10) has a frame which consists of three sectional pieces (12, 14, 16). The sectional pieces are extruded aluminium sections. The upper arm (12) and the yoke (16) on the one hand, and the latter and the lower arm (14) on the other hand, are connected positively to one another. Provided for this purpose in one sectional piece are webs which extend in the longitudinal direction of the section and are pushed into transverse grooves (42) of the respectively connected sectional piece. The positive connection guarantees absolute parallelism of the two arms (12, 14). The frame is easy to assemble. The sectional pieces can be locked by means of bolts (50, 56). Various sizes of axle differ solely in the differing lengths of the arm (12, 14) and, if required, different heights of the yoke (16). <IMAGE>

Title: Device for indicating and/or storing errors of transmitter arrangements on internal combustion engines
Inventor: DENZ HELMUT
IPC: F02B75/18
Filed: 1983-03-05
Abstract: In this device, a reference mark generator (13) coupled to the crankshaft generates at least one reference mark per revolution and a further signal transmitter, particularly a phase signal transmitter (14) coupled to the cam shaft is provided for generating further transmitter signals which have a fixed correlation with the signals of the reference mark transmitter. In the event of a deviation from the prescribed order and prescribed distances of references marks (r) and further transmitter signals (p), an error signal is generated which is stored and/or supplied to a display device (15). In this manner, it is possible to detect not only missing pulse sequences and thus faults in the transmitter arrangements or feedlines but also intermittent contacts and angle displacements of the transmitter signals with respect to one another.

Title: Process for the reusability of sludges
Inventor: WEFELS FRITZ G D
IPC: C02F11/121
Filed: 1983-04-02
Abstract: The invention relates to a two-stage process for the reusability of sludges from industrial or municipal water and waste water treatment plants. In the first stage of this process, a part dewatering of the sludge is carried out up to a solid content of 15-70% in the filter cake, solely by mobile dewatering devices, and in the second stage a long-term composting of the outputs of the mobile dewatering units is carried out. As a result of this, the high investment costs, the maintenance costs and operating costs are avoided, as are the working agent costs of stationary dewatering units, which are replaced by the mobile dewatering units operating in optimum efficiency. Moreover, considerable costs are avoided by passing on or further processing of the resulting filter cake quantities by drying units, combustion units but also by shipping costs and landfill costs, and also by high consequential costs in the form of further treatment plants intensive in terms of machinery and operators, such as combined refuse/sludge composting, bioreactors etc. The procedure of the invention makes possible a recycling of the sludges to be treated, where the humus fractions and the components of the sludges active as fertilisers can be exploited to the full.

Patent DE-3405769-A1 (DE)
Inventor: PEPPEL J MICHAEL DIPL ING
IPC: H03K17/06
Filed: 1984-02-17
Abstract: A method and apparatus to maintain the current-conducting state of a gate-turn-off thyristor by appropriate triggering. To maintain the thyristor's current-conducting state reliably and with little ignition energy consumed, a comparator signal is generated as soon as the voltage drop across the thyristor exceeds a preset limit value by a comparator stage. The comparator signal has a preset duration defined by a pulse duration limiting stage, and, if necessary, a subsequent pulse magnitude limiting stage can change the pulse magnitude as a function of the interval between two subsequent ignition current pulses. A controllable current source connected to the thyristor gate is controlled by these magnitude and duration limited pulses, but this controlled current source only triggers the thyristor when the limit value is exceeded.

Title: Measuring method for checking protective measures in electrical installations and measuring instrument for carrying out the method
Inventor: ZIEGLER HERBERT
IPC: G01R31/28
Filed: 1984-06-13
Abstract: The checking of earth-leakage circuit breakers is of particular significance when checking protective measures in electrical installations. To increase the safety, the method should basically proceed in such a manner that the disconnecting characteristic of an earth-leakage circuit breaker can only be checked after the touch potential has been determined. Compared with known methods, the sequence of the measurement should become significantly accelerated and the operation of the measuring instrument used should be facilitated. For this purpose, an automatic measuring system determining the sequence of the measuring method is provided which, after the touch potential has been determined, interrupts the measuring sequence before the earth-leakage circuit breaker contained in the protective circuit is switched off. To continue the measuring sequence for checking the disconnecting characteristic of the earth-leakage circuit breaker, a manual switch must be operated. The manual switch is electrically interlocked in such a manner that it only allows the measurement to be continued if the touch potential determined does not exceed the permissible range. <IMAGE>

IPC: E04F21/05
Filed: 1984-10-03
Abstract: The invention aims to provide the plasterer with an implement by means of which he can erect vertical plastering screeds more quickly and better. This permits a wider application of the plastering screeds and thus an increase in quality of the wall plaster. The invention comprises a special straightedge which is provided in the longitudinal direction with a profile into which certain plastering screeds fit. When they are closed, securing means which can rotate about an axis prevent the plastering screed from falling out frontwards and a profile base prevents them from falling out downwards. When in use, the plastering screed, together with the special straightedge, is pressed into the fresh mortar and brought into the vertical with the aid of a built-in levelling means. The special straightedge can be removed once the securing means have been opened, the plastering screed remaining on the wall.

Title: Arrangement for improving a video signal
IPC: H04N5/228
Filed: 1984-10-10
Abstract: In addition to eliminating the image flickering of a video camera which is periodically unilluminated, a further improvement in the image quality is achieved in that the process for reading out a frame or a field from the video camera does not start until the light provided is interrupted, and is ended as soon as the relevant frame or field has been completely read out. Improved horizontal resolution of the image for a given memory capacity, or a lower memory capacity of an image memory for a given horizontal resolution of the image, can additionally be achieved by storing a completely coded signal with a colour-subcarrier phase which is constant with respect to the H-phase and the V-phase. A colour conditioner after the image memory can be provided for reproducing a standardised field sequence.
