Title: Signal processing
Inventor: RICHARDSON TREVOR
IPC: H04N5/14
Filed: 1982-02-03
Abstract: A d.c. biasing signal 10 which varies periodically is added to a video signal (Figure 2B) which has noise superposed thereon. Normally, the noisy video signal would have significant excursions (3, 4, 5, 6, 7, 8) which lie outside the input range (0 to 100%) of an analogue-to-digital converter. However, addition of the biasing signal 10 gives a composite signal (Figure 4B) of which the noise excursions lie better within the range of the analogue-to-digital converter. Subsequent processing of the digital signal compensates for the d.c. biasing signal 10. Basic circuits are disclosed, for carrying out the addition of the biassing signal 10 and video signal.   <IMAGE>

Title: A method of utilizing the energy in the surface waves in a body of liquid, such as waves on the surface of an ocean, and equipment for carrying out said method
Inventor: HERTZ KRISTIAN DAHL
IPC: F03B13/18
Filed: 1983-08-01
Abstract: In a method and equipment for extracting surface wave energy by using flexible tubes (2) divided into sections interconnected by non-return valves (4ab-4jk) opening in the same direction, each section is divided into two chambers by means of a slack, flexible fluid-tight membrane (9), viz. 1) a first chamber or air chamber (7a-7k) which is closed on all sides and adapted to contain a gas or a gas mixture, such as air, and 2) a second chamber or water chamber (8a-8k) communicating with the preceding and succeeding second chamber or water chamber (8a-8k) through the non-return valves (4ab-4jk). The air chambers (7a-7k) act as pressure accumulators accumulating pressure energy when the particular section is lowered, releasing the accumulated energy during the subsequent upward movement by forcing some of the liquid in the water chamber through the downstream non-return valve (4ab-4jk). Thus, a pumping effect is attained, which may be used for driving a turbine or the like. The air chambers (7a-7k) further give buoyancy to the flexible tube, so that separate buoyancy means, such as previously used flexible surface floats, may be dispensed with. The flexible tubes (2) and/or the transverse walls (3ab-3jk) may be manufactured from low-cost plastic material, such as glass-fibre reinforced plastic foil, and at least part of the manufacturing process may be carried out on or near the final site, thus further reducing the cost.

Title: Negative climb after take-off warning system
Inventor: PATERSON NOEL S
IPC: G01C5/00
Filed: 1984-11-14
Abstract: A warning system for aircraft compares the rate of descent of the aircraft with its altitude above ground after take-off, and generates a warning if the aircraft is experiencing an excessive descent condition for the radio altitude at which the aircraft is flying. The relationship between radio altitude and descent rate required to generate a warning is optimized for small, high performance aircraft such as fighter or attack aircraft. The system is operative in an altitude band of 20 feet (6.096 metres) and 100 feet (30.48 metres) and is inhibited if the airspeed exceeds 200 knots (370.5 kilometres/hour). A warning is generated if the descent rate exceeds 125ft/min (38.1 metres/min) at 100 feet or 25 ft/min (7.62 metres/min) at 20 feet, with linear variation of warning descent rate between these altitudes. <IMAGE>
