Title: Current converter for small machine - uses control current to phase shift positive and negative current blocks to overlap and improve open circuit running
Inventor: SCHOERNER JOCHEN DR ING
IPC: H02M7/527
Filed: 1979-10-08
Abstract: The current converter is operated by a control system so that its basic oscillation is varied not only by the amplitude of the positive and negative current blocks applied, but also by phase position and the time of application of the blocks. These blocks are first shifted by 120 degrees so that they overlap and so that the output current is nil during the overlap. While current flows again through the driven device, during a completely overlapping period, the inverter remains ready to operate and is then held open circuited. The system is suitable for machines under small loads, for multiple motor drives for a variable number of machines and for drives with a high field attenuation region. The sliding action of the positive and negative current blocks is caused by a control voltage.

Title: Time base change for tape recording and playback appts. - uses superimposition of recording or replay head velocity component on time changed velocity component
Inventor: MANGOLD HANS DIPL ING
IPC: H04N5/783
Filed: 1980-02-28
Abstract: The time base changing process is intended particularly for oblique track recording and for attaining speed changed for playback, in conjunction with certain magnetic head arrangements. A velocity component of identical or opposite direction of the recording or scanning heads (14-16) is superimposed onto the velocity component of the tape (11a,17) during recording, or playback respectively, the component being changed by extended or compressed time interval. The superimposition is such that the total velocity of the tape is formed as an effective relative velocity between the tape and the respective heads. The time base change may take place both during recording and playback. In the device for this change the tape is guided past a rotatable head carrier, which is stationary in normal operation. The carrier is rotatable in one of two directions according to the required time base change. The tape contact contains two image frames.

Title: Compensating circuit for intermodulation interference of VHF signal - interference signal being filtered out by anti-parallel diodes and inverted, esp. for third order interference
Inventor: YENERIM SAVAS DIPL ING DR
IPC: H03F3/189
Filed: 1980-06-28
Abstract: Interference due to intermodulation in a VHF-receiver, i.e. third order intermodulation products in an aerial amplifier, is compensated in this circuit without loss of bandwidth and negligible extra power by the use of two diodes connected opposite/parallel. The incoming VHF-signal (13) is coupled via capacitor (21) to two parallel/opposite diodes (23,26). Due to their non linear characteristic intermodulation products of the third order are produced whose amplitude may be varied by regulating the direct current of the diodes. The signal is then passed through a high- pass filter (29) and is inverted (31) before being mixed (32) with the incoming VHF-signal.
