Title: Cine film sound synchronising system - has separate magnetic tapes driven at constant speed by single capstan linked with film drive
IPC: G03B31/04
Filed: 1976-04-28
Abstract: The sound recording and synchronising system for a cine film uses magnetic tape. The system can simultaneously accommodate several magnetic tapes driven in synchronism by a common drive.

Title: Phase locked loop for Doppler system - has clocked switch reversing phase of reference signal applied to phase detector
Inventor: LALANDE JACQUES ALFRED
IPC: H03L7/093
Filed: 1976-07-29
Abstract: The phase locked loop, for Doppler systems, compensates phase errors using relatively few circuit components. The vco is controlled by the output of an amplifier (5) with bipolar gain switching (4). The gain-switch switching circuit is controlled by a clock signal derived by frequency division (c) of the output of the VCO. This clock signal is used to control a second switch (8) that reverses the phase of the reference signal applied to the phase detector (1) (followed by an LP filter (2)). The two oppositely-phased reference signals are derived from the two outputs of an oscillator (7) clocked by the output of the VCO.
