Patent GB-2090939-A (GB)
Title: Power generating apparatus
IPC: F03G3/00
Filed: 1981-01-10
Abstract: Bucket 18 fills with water from discharge pipe 23 until the combined weight of water and bucket overcomes the bias of counterweight 19, to which bucket 18 is attached by chain 20, via pulleys 21. Bucket 18 and its contents descent with pivoted carriage 25 to a lowered position where said carriage 25 stops and bucket 18 pivots to a horizontal position to discharge its contents. Descent of counterweight 19 pulls empty bucket 18 back to its upper rest position, and the cycle repeats as long as there is water in reservoir 24. Motion of chain 20 produces rotational movement of free-wheel 17 which drives flywheel 14 when bucket 18 descends, but not when it ascends. Rotation of flywheel 14 drives dynamo 15, in a belt 16, to produce electricity. Variations include use of two counter-rotating flywheels, arranged so that one engages freewheel on descent of bucket, other on ascent. Alternatively the counterweight may be replaced by a second bucket operating 180 DEG  out of phase with first bucket. <IMAGE>

Title: Apparatus for desalinating water by reverse osmosis
IPC: E03B3/04
Filed: 1981-01-15
Abstract: In a reverse osmosis plant for desalinating seawater or brackish water the osmosis cell or cells (1) are located at a level sufficiently below the saline water supply (6) and the brine discharge point (8) so that the hydrostatic pressure resulting from head (2) provides the major component of the pressure at the saline side of the osmosis cell or cells needed to bring about reverse osmosis. The osmosis cell or cells may be located about 500 metres underground and purified water pumped (9) from the cell or cells to the surface. By this means the power consumption of the plant is substantially less than that of a conventional reverse osmosis plant.   <IMAGE>

Title: Beverage dispenser security device
Inventor: MILES BARRY THOMAS
IPC: G01F15/00
Filed: 1981-05-29
Abstract: A security device, for preventing subsequent withdrawal of a feed tube (9) from the neck (1) of a bottle without destroying a liquid- tight seal between the bottle and/ or giving a readily visible indication that withdrawal has at least been attempted has a bung (2) for securing in liquid-tight manner to the neck, and a feed tube for insertion into a passage of the bung providing communication between the interior and the exterior of the neck. The feed tube has a detent (10) which is so arranged as to permit relatively unimpeded movement along the passage in the direction of insertion, but which prevents reverse movement without thereby causing at least partial deformation of the bung to the extent that it cannot thereafter receive a similar feed tube in liquid-tight engagement. <IMAGE>

Title: Surge protection circuits
Inventor: AHUJA OM P
IPC: H02H9/06
Filed: 1981-12-16
Abstract: A surge protection circuit (10) for use with telephone lines or circuits having logic elements or the like incorporated therein includes the usual gap arrester (15), a heat-sensitive switch (16), and a transient suppressor (17) providing a parallel interconnection between the protected line and source of ground potential (14).

Patent GB-2094085-A (GB)
Title: Deflection circuit
IPC: H04N3/18
Filed: 1982-02-15
Abstract: A deflection generator (60) of a television receiver is coupled to a deflection winding (LH) for generating scanning current during a deflection cycle. The generator includes a retrace capacitor (C13) coupled to the deflection winding (LH) for forming a resonant retrace circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor (L1) and another capacitor (C5) form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement (S1, S2) is coupled to a source (24) of energy and to the second resonant circuit. The switching arrangement (S1, S2) is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source (24) in the second resonant circuit (C5, L1); the amount of energy thus stored is controlled by controlling the conduction times of the switching arrangement. This stored energy is then transferred to the resonant retrace circuit during the retrace interval to replenish losses sustained during the deflection cycle. <IMAGE>

Patent GB-820530-A (GB)
Abstract: 820,530. Cold-cathode tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 19, 1957 [June 22, 1956], No. 19304/57. Class 39(1). In a glow-discharge tube comprising a main anode and an auxiliary electrode arranged at opposite sides of a main cathode, an opening in the cathode is provided with a rim which extends away from the anode and into which the auxiliary electrode extends without projecting from the main cathode surface. This construction, by partly shielding the auxil. iary discharge from the anode field, reduces the possibility of the rectifying effect being lost when an alternating voltage is applied between the anode and the cathode with the auxiliary electrode at a given positive bias. As shown, a graphite anode 6 supported on a supply conductor covered with enamel 7 is surrounded by a nickel shield 9 provided with a coating of radioactive material 11 for avoiding ingition delays. The cathode 3 and auxiliary electrode 5, both of molybdenum are provided with supply conductors surrounded by glass tubes in order to avoid short-circuits. A flexible wire 10 is provided to make contact with the layer which would be produced on the envelope 1 as a result of cathode disintegration at high current densities. The tube is filled with a mixture of 75% neon and 25% argon at a pressure of 75 mms.

Patent GB-2112015-A (GB)
Title: A process and apparatus for cooling and purifying a hot gas
Inventor: STIL JACOB HENDRIK
IPC: C10J3/84
Filed: 1982-04-01
Abstract: Hot crude synthesis gas leaving a gas generator at the top in upflow is quenched by injection of cold purified synthesis gas. The gas velocity is reduced and the gas stream is reversed downflow. The gas velocity is increased again. The gas stream is reversed in upflow and the gas velocity is decreased. A separation of part of the fly ash from the crude synthesis gas is obtained before it enters into a waste heat boiler. Therefore the WHB is less prone to blockage. The gas is further indirectly cooled in the WHB, flyash being separated.

IPC: H03K5/13
Filed: 1983-03-25
Abstract: A timing pulse generator includes a bootstrap capacitor (CB). This capacitor having been brought into a discharged state in advance in charged up when one terminal is fed with an input pulse ( phi IN) through a transmission gate MOSFET (Q5). A boosting pulse to be applied to the other terminal of the capacitor is generated at a suitable timing to generate a boosted voltage. A voltage detector including MOSFETs (Q6- Q10) is provided for detecting the charging voltage level of the capacitor. The timing at which the boosting pulse is generated is controlled by the voltage detector, thereby minimising the effect of input pulse level, temperature and other changes in component characteristics on the timing of the output pulse, ensuring reliable operation and minimising switching time and heavy current consumption resulting therefrom. <IMAGE>
