Title: Synchronisation of switching in parallel connected semiconductors - using additional delay elements as trimmers
Inventor: WOHINZ WOLFDIETRICH
IPC: H02M1/088
Filed: 1974-09-02
Abstract: The additional elements artificially overcome the inherent scatter of switching on times, for example, in parallel connected thyristor circuits, in order to ensure equal current sharing and thereby avoid gross overloading of a few devices. Between the gate pulse generator (SE) and the gate terminals of each of the controlled semiconductors (T1-T4) a delay element (MK1-MK4) is inserted. These elements have adjustable delay times, and each parallel path is adjusted until the total delay time is the same in each case. Typically, the semiconductor with the longest inherent switch on time has no additional element is its gate circuit.

Title: Positioning device with stereoscopic display - uses two echo sounding devices and two oscilloscopes
Inventor: SEIFFERT MANFRED DR
IPC: G01S7/62
Filed: 1974-12-03
Abstract: The method uses an echo sounding principle to form three dimensional means by the use of two echo sounders and two oscilloscopes. A saw tooth waveform generator is employed to form a fine base so that sequential images may be produced and viewed by a suitable eyepiece combination. The pulses are plotted on a special co-ordinate system with displacement in the x and y directions based on time displaced responses and using either a square or a trapezoidal grid to establish the images. The use of two sounders and visual display permits more rapid object location than a computational analysis of azimuth, elevation and distance obtained from a single survey unit.

Title: Surface profile scanning device - tested object is moved at right angles to direction of movement of scanning sensor
Inventor: RAITH SIEGFRIED DIPL ING
IPC: G01B11/30
Filed: 1975-06-25
Abstract: The sensor determines the deviation of the object's surface from a surface assigned as a datum surface. The sensor is in the form of a white light two-beam interferometer, whose optical parth's length difference between object and reference beam is wobbled by more than the coherence length of the light used, so that interference phenomena appear periodically when the path length of the reference beam coincides with that of the object beam. Interference phenomena are converted by a photodetector into an electric signal, from which a processing device derives the deviation of the tested surface, including the deviation sense.

Title: Fusion welding current source control - by flip flop with timing pulse generator and comparator controlling transistor
Inventor: HAHN GUENTER
IPC: B23K9/073
Filed: 1975-06-28
Abstract: The welding current source for arc, plasma and electro-slag welding, with a switching frequency of 16 kHz is controlled by a correcting element in the power line to the electrode. A flip flop which is linked to the correcting element through a power amplifier can be turned on by the output signal from a timing pulse generator and turned off by the signal from a comparator for the desired and actual value of current or voltage. This makes it possible to use digital units for both actual and desired value setters, with the result of lower costs and higher control accuracy. The setting of the desired value by computer or punched tape is facilitated, and the digital display of the actual value results in better supervision.
