Title: Keying circuit for modulating transmitted carrier frequency - has pulse shapers for output and other stages, each with timer
Inventor: DRIESNER JOERN DIPL ING
IPC: H03C1/00
Filed: 1975-07-04
Abstract: An electronic keying circuit which delivers pulses at short intervals for keying the modulated transmitted carrier frequency, has a sender with at least one active stage before its output stage. A pulse shaper is allocated to the output stage and each preceding stage, and a common timer is provided for all pulse shapers. The timer delivers approximately rectangular individual keying pulses having the same period, to each pulse shaper. Pulses for the individual pulse shapers differ in width and phase, so that the output stage is switched on after preceding stages, and switched off before them. The pulse shapers round off the edges of the pulses from the timer.

Title: Automatic dynamic compander circuit for recording systems - provides selective suppression of pilot signal in stereo systems to minimise distortion effects
Inventor: SCHROEDER ERNST DIPL ING
IPC: H03G7/00
Filed: 1975-09-24
Abstract: A dynamic compander circuit is used for improved signal processing in a sound recording system.

The negative input of the differencing amplifier is coupled to a loop containing an impedance (20) and also to a relay (25) connected to a controlled (22) impedance (21). A third impedance (23) is coupled to ground. A relay (19) either takes the filter output or provides a by-pass.

Title: Pulse regenerator which detects input pulses - fuctions at given time points and passes pulses to output for duration of clocking
Inventor: BOEDEKER FRIEDRICH ING GRAD
IPC: H04L25/24
Filed: 1975-10-28
Abstract: The pulse regenerator detects the presence of a pulse at discrete time points quickly and passes it on to the output as long as clock pulses are present. The regenerator is cheap, consumes little power and can handle low to very high clock frequencies. The input signal (D) is applied to a first transistor switch (T1) whose output can be shorted by a second switch (T2)-- which is controlled by the output of the regenerator and which itself controls a third switch (T3) whose output forms the regenerator output. This part of the circuit is repeated (T5, T6, T7) for the clock pulse input (T).

IPC: F21V21/116
Filed: 1976-09-28
Abstract: In a known device for fastening a mast-head luminaire having a connecting piece, a bow which can be hung over permits the luminaire to be fastened at or on a mast end, which can thereby be clamped against stop faces situated at the rear or top in the connecting piece. The invention is attended by a substantial simplification which can be applied in the case of smaller luminaires. The present device consists in a wedge piece (4), which is arranged pivotably and secure against rotation and which can be clamped by a screw (5) against a mast end (2) inserted from below; a mast end (2') inserted from the rear is directly clamped by the screw (5), the nut (51) being guided in the wedge piece (4) in a manner incapable of rotation. <IMAGE>
