Patent DE-2819958-A1 (DE)
Title: Magnetic recording head with angled working gap - dimensioned so that edges of adjacent tracks have opposing magnetisation allowing narrow spacing
Inventor: POEHLER HERBERT
IPC: G11B5/23
Filed: 1978-05-06
Abstract: The magnetic head for audio and/or video signals has a working gap which runs at an angle to the longitudinal direction of the recording track. The working gap extends in two different directions at least in the region of the two edges (3) of the recording track (4), e.g it is arrow-shaped. This angling of the working gap causes the subsequent magnetisation (5) of the recording track to follow a similar configuration, so that the overlapping edges (3) of adjacent tracks are magnetised in different directions, allowing the tracks to be more closely spaced.

Title: Discharge lamp with starting current limiting series circuit - has integrated module fitting in socket switching current on and off via feedback pulse
Inventor: STEIN KARL-ULRICH DIPL ING DR
IPC: H05B41/285
Filed: 1979-01-11
Abstract: The series circuit for a gas discharge lamp limits the starting current. It can be constructed as a module and fitted in a relatively small socket of the discharge lamp. It is an improvement on the current limited choke as regards weight and volume. The main connections (3, 4) are connected to a suppressor (5) of modular construction. The compressor feeds a rectifier bridge (8) which supplies a semiconductor switch (11), which is controlled by pulses from a control module (15). The current in the discharge lamp is limited by periodically switching the current on and off. This is performed by the semiconductor switch which is controlled by a feedback circuit supplying pulses. The control pulses are derived from a sensor attached to the tube. The operating conditions are typically 350 volts. 0.3 to 1.0 amp, and a frequency of 1 MHz.

Title: Skidding vehicle speed detector - has circuit producing error signal to denote open circuit fault condition
Inventor: GEIER GEORG
IPC: B60T8/88
Filed: 1979-10-20
Abstract: A detector circuit is connected to antiskid and antislip equipments in order to transmit their speed.
