Patent GB-2195510-A (GB)
Title: Removing pseudo-sync and/or agc pulses from video systems
Inventor: RYAN JOHN OLIVER
IPC: H04N5/913
Filed: 1987-09-16
Abstract: Added pseudo-sync pulses and AGC pulses are removed from a video signal to enable acceptable video recording thereof. The added signals previously interfered with acceptable video recording of the video signal because the automatic gain control of videotape recorders sensed false recording levels, while conventional televisions receivers were unaffected by those modifications to the video signal. Removal of the added pulses permits acceptable video recording of the previously modified video signal. A selectively-operable clipping circuit is used to remove selected negative-value components (i.e., pseudo-sync pulses) from the video signal, while added AGC pulses are effectively blanked from the video signal with an electrically-operable switch. Both the blanking and clipping functions are selectively achieved by sensing both the normal sync pulses of the video signal and the added pseudo-sync pulses. Method and apparatus are disclosed for "cleaning up" video signals modified by the pseudo-sync pulses alone, the AGC pulses alone, or combinations thereof.

Title: Electric space heaters
Inventor: STOKES EDWIN ERIC
IPC: F24C7/08
Filed: 1988-04-19
Abstract: An electric fire has a tray (24) supporting base members (25, 26) in which a single continuous, coiled resistance wire first heating element is mounted. A convection air heating element (37) is located in a convection air passage (33). The two heating elements are connected in series so that the voltage drop across each one is less than mains voltage. The first element may therefore be made of heavier gauge wire with a longer life. Alternatively the first heating element may be in series with a diode. Pieces of imitation solid fuel are disposed above the first heating element to be heated thereby and radiate heat. Spaces between the pieces allow glimpses of the glowing element to be seen, providing a realistic appearance of burning solid fuel. <IMAGE>

Title: Method for measuring the natural vibrational frequency of a submarine pipeline free span
Inventor: HOLT RICHARD JOHN
IPC: G01M7/02
Filed: 1989-06-15
Abstract: A method for measuring the natural vibrational frequency of a submarine pipeline free span involves using the thrust of a suitably positioned remotely operated vehicle (ROV) to excite the pipeline at its free span. The vibration response of the span is measured by an accelerometer (1) mounted on the ROV. The accelerometer (1) is positioned within a pressure housing (4) and is linked by cable (5) and receptacle (6) via the ROV umbilical to recording equipment on the surface. By measuring the natural frequency the susceptability of a pipeline free span to potentially damaging vibrations e.g. caused by vortex shedding, may be determined. The signal processing may include a correction to take account of the added mass of the ROV. <IMAGE>

Patent GB-2243217-A (GB)
Title: Proximity detector for use on doors
Inventor: TRETT JOHN
IPC: B66B13/26
Filed: 1990-04-20
Abstract: A proximity detector has four main sensors (5a to 5d) located at spaced intervals along a door edge at positions suitable for detecting a predetermined class of objects. Two differential amplifiers (7a and 7b) compare the outputs from alternate pairs of sensors (5a, 5c and 5b, 5d) and produce a control signal if the compared outputs differ by more than a threshold value. An auxiliary sensor (6) is situated at or towards the door edge at a position where it is substantially unaffected by the approach of the objects intended to be sensed by the main sensors but where it is affected by the surface against which the door closes. The output from the auxiliary sensor (6), is used as the space between the door and other surface varies, to alter the threshold value to which the differential amplifiers (7a, 7b) respond. Sensors (5a to 5d) are capacitive sensors and sensor (6) may be a capacitive, infrared or acoustic sensor. Sensors (5a to 5d) may be mounted in a guard channel. <IMAGE>
