Patent DE-2630322-A1 (DE)
Title: Circuit element to determine deviation in frequency - uses two NOR gates to form two signals revealing deviation of frequency from nominal value
Inventor: SETTFORS JAN DIPL ING
IPC: G01R23/12
Filed: 1976-07-06
Abstract: Deviation determination of an actual frequency from a nominal frequency is by the use of two signals. Both frequencies relate to rectangular waveform oscillations. The first signal determines the value and the second signal determines the direction. The nominal frequency is compared with the actual frequency divided by an integral factor. The phase of the divided actual frequency for determining the direction is out of phase in comparison with the phase of the divided actual frequency. With the aid of one (G1) of two NOR-gates (G1, G2) the rectangular oscillations (a, b) i.e. nominal and divided actual frequencies are compared.

Title: Digital LF power amplifier system - converts LF analog signal by coding amplitude as duty factor and frequency as rate of change of duty factor
Inventor: EISENMANN PETER
IPC: H03F3/217
Filed: 1976-07-13
Abstract: The digital LF power amplifier is compact and cheap and has high efficiency with low distortion. The analog LF signal is converted into a digital signal such that amplitude codes as duty factor and frequency as rate of change of duty factor. A sawtooth generator is connected into a resistance bridge diagonal. Rectangular pulses whose pulse width is inversely proportion to the LF signal amplitude, appear at the output of a Schmitt trigger. This output signal is amplified and stored magnetically as a digital audio signal.

Title: Calorimeter for laser beam welding energy check - has thermistors for measuring temp. of twin copper cone and ambient temp.
Inventor: SCHOELER ULRICH
IPC: G01K17/00
Filed: 1977-03-29
Abstract: Calorimeter to check the welding energy of a laser beam, e.g. in a welding automatic for sheet metal, has one thermistor to measure the temp. of a twin copper cone, heated by the laser beam, and a second thermistor to measure the ambient temp. A differentiator determines the point when the cone has reached its max. temp. A voltmeter, calibrated in energy units is connected with its trigger input to the differentiator, with its non-inverting input to the first thermistor, and with its inverting input to a voltage store with a capacitor. The arrangement saves the long waiting times between individual measurements for the max. temp. to cool down to ambient temps. The measurement can be carried out in quick succession, yet they produce very accurate results.
