Title: High-stable quartz crystal oscillator - has low current consumption and uses controlled reactance compensating frequency drift due to temp. changes
Inventor: WEINZIERL FRANZ DIPL ING
IPC: H03L1/02
Filed: 1980-04-12
Abstract: The quartz crystal oscillator has a voltage-dependent reactance compensating for drift in frequency due to temperature changes. The operating temperature range is divided into intervals. A digital memory stores a tuning voltage for each interval. The tuning voltages are applied to the reactance to maintain the frequency constant. Each temp. interval has a storage address. Each address in the memory contains a digital word describing the tuning voltage associated with that interval. The storage address is a digital work obtained via an A/D converter (4) from a temp./voltage converter (13). The stored word is converted into an analog AFC voltage via a D/A converter (6). The temp. of the oscillator is measured at an appropriate place, i.e. at the crystal itself or at the oscillator casing.

Title: Secam TV signal transmission system - has no distortion by splitting signal into luminance and chrominance components feeding two converters
Inventor: MAYER NORBERT DR ING
IPC: H04N11/18
Filed: 1980-09-16
Abstract: A television installation is used for transmitting SECAM signals free of any distortions via three digital component channels. The signal is split into a luminance and a chrominance component at the transmission end. The frequency band of the chrominance signal is folded into two parts before being scanned. It is then shifted into a lower frequency range while a quadrature phase shift is introduced between the two converters. The output signals of the converters are scanned separately and transmitted together with the scanned values of the light density signals. Two converters are installed at the receiving end to reconstruct the signals into their original frequency positions. The undesirable components are made to cancel out.
