Title: Colour television convergence corrector - uses scan drives to provide correction waveforms and is integrated with scan coils
Inventor: NISSEN ALEX JR
IPC: H04N9/285
Filed: 1974-12-18
Abstract: This circuit is used in a colour television receiver for the convergence correction of an in-line gun tube. The line (H) and frame (V) scans are normal but a connection is made from each scan coil to this correction circuit.

Title: Multiple control signals transmission on single carrier - involves addressing information determined by sequence of useful data and modulating onto carrier
IPC: G08C15/00
Filed: 1975-05-13
Abstract: Remote control of several objects such as cranes is performed using digital transmissions on a single carrier frequency. Addressing problems increase total message length w.r.t. Useful data. This is overcome by transmitting addressing information which is determined by the sequence of useful data. In a transmitter the signal for a particular controlled object is frequency modulated and is of specific length. The signal is received (8) and the first pulse unlatches a clock generator (9). A counting and processing circuit (10) examines the message for time coincidence and if satisfactory the message is stored (11). A second counting and processing circuit (12) determines if the number of information signs received coincides and is so the information is loaded into a memory (13) for decoding (14).
