Title: Adaptive aerials and comb filters
IPC: H04N17/00
Filed: 1979-05-08
Abstract: Apparatus for detecting co-channel interference in a transmitted T.V. signal comprises means for producing a difference signal (???¦A¦-???¦B¦) between the sums ???¦A¦ and ???¦B¦ of the amplitudes of the two pulse sequences formed by taking alternate sync pulses, the sequences being formed by de-interleaving the received sync pulses. Derivation of the difference signal involves deriving the sum and difference between successive sync pulses for filtering, and sampling at line rate, thence passage to a logic unit where amplitude signals A, B of individual sync pulses are re-constituted for summation, and formation of the difference signal. The difference signal is used as a control signal for an adaptive aerial or a comb filter for attenuating the co-channel interference. Operation relies upon the change in sync pulse amplitude produced by heating resulting from the interference.

Patent GB-2049207-A (GB)
Title: Camera exposure control circuit
IPC: G03B7/095
Filed: 1980-02-26
Abstract: The camera has a selectively operable memory circuit 6. As shown diaphragm aperture A is calculated according to measured subject brightness and pre-set exposure time T, and A and T are stored at 7 and 8. On release, the diaphragm stops down as near as possible to A, then subject brightness is measured again, through the diaphragm, to alter T in accordance with any deviation from A. If subject brightness changes between the two measurements, an error would be made. To avoid this, a switch 17 is manually operable to actuate the memory 6 which records any changes in brightness and compensates the exposure time accordingly. Deliberate under- or over- exposure may be made by closing a switch 18 to alter the value stored in memory 6. <IMAGE>

Title: Variable Speed Hydraulic Transmission
IPC: F16H61/42
Filed: 1980-07-25
Abstract: Single acting hydraulic cylinder actuators (35, 45) for adjusting the swash plate tilt in a pump (15) are connected to a charge pump (P) and to respective bypass valves (33, 37) which are solenoid valves, open when de-energised. As illustrated the system is in neutral with both valves open and the swash plate at zero angle. To set a desired pump displacement, a control circuit (52) closes one solenoid valve and the corresponding actuator (35 or 45) tilts the swash plate. When the desired tilt has been reached, as indicated by a feedback transducer (59), the circuit 52 energises also the other valve and both hydraulic actuators are pressurised to lock the swash plate in position. The system requires a minimum of electrohydraulic parts, namely the two simple solenoid valves (33, 37). In an alternative embodiment the swash plate of the motor can be adjusted in a similar manner to permit a further increase in output speed to be obtained after the pump swash plate has been displaced to its maximum extent. <IMAGE>
