Patent DE-2812774-A1 (DE)
Title: Synchronisation pulse supply procedure - derives pulses from time signals of transmitter or from transmitter with very constant frequency, or from auxiliary oscillator
Inventor: HEIL GEORG DIPL PHYS DR
IPC: H04L7/00
Filed: 1978-03-23
Abstract: The pulses are used for data transmission by radio between stations, using time signals transmitted by a time transmitter. Each stations derives synchronisation pulses from the second signals of the time signal transmitter. In case of failure of the time signal transmitter synchronisation pulses are derive from a transmitter with highly constant frequency, which maintains the frequency and phase of synchronisation pulses transmitted by the time signal transmitter. Only in the case of a simultaneous failure of the time signal transmitter and of the constant frequency transmitter are the synchronisation pulses derived from an auxiliary oscillator also maintaining phase and frequency, the latter with lower accuracy.

Title: Synchronisation of controllable oscillator reference signal with input - uses signals proportional to difference between two frequencies for oscillator control
Inventor: HEYDT GUENTER ING GRAD
IPC: H03L7/10
Filed: 1978-06-12
Abstract: A phase control circuit with two phase discriminators generates two control signals with a 90 deg. phase difference, whose frequency is equal to the difference between the frequencies of the reference and input signals. A signal is derived, whose amplitude is proportional to this difference frequency. It is used for the oscillator control. Pulses are generated at each second zero crossing by the first control signal, and amplitudes proportional to the pulse frequency are applied to the other control signal. Thus an additional control signal is applied to the oscillator, whose polarity and amplitude correspond to those of the difference frequency.

Title: Loudspeaker moving coil excess temp. indicator - has diode-decoupling capacitor stage connected to voltage stabiliser to produce DC voltage across coil receiving audio power from amplifier
Inventor: BERGK GUENTHER
IPC: G01K13/00
Filed: 1979-11-26
Abstract: The temperature of a loudspeaker moving coil is measured while receiving audio power from an amplifier by deriving a d.c. voltage via a diode (6) which may be connected to a voltage stabilising circuit (24) jointly with a decoupling capacitor (25). The d.c. voltage is applied to the moving coil (2) via a resistor (7) and the resulting d.c. voltage drop to ground is applied to the noninverting input of an operational amplifier (13) via a choke (18). For comparison, a variable voltage divider (8,11,10) supplies another input to the inverting terminal which is connected to the amplifier output via resistor (27) in a negative feedback fashion to adapt to the instrument scale (26) which may be calibrated in centigrade. In place of the instrument light emitting diodes may be used to indicate when excess heat is developed and in that case no negative feedback is required.
