Title: Improvements in flares
Inventor: WILKINSON RONALD DOUGLAS
IPC: F23G7/08
Filed: 1970-03-16
Abstract: 1299212 Flare stack burners AIROIL BURNER CO (GB) Ltd 16 March 1970 12502/70 Heading F4T In a flare stack, particularly one of low overall height, for burning waste gas, the gas enters a hollow body 10, via an inlet 43 and passes up through chamber 30, down through chamber 31 and up through chamber 32 to a flare tip outlet at the upper end of the body, the chambers 30, 31 and 32 being disposed to form a gaseous seal to prevent air passing from the outlet to the inlet when the flow of waste gas, which is of lower density than air, is interrupted. Chamber 30 is formed by part of the inside of the body 10 and a surface defined by two vertical walls 16 and 17 and part of the surface of a cylindrical member 11, chamber 31 by the rest of the inside of body 10 and the rest of the outside of cylindrical member 11 in combination with walls 16 and 17, and chamber 32 by the interior of member 11, the lower end of which has a section cut away to provide an inlet 23. An arcuate shaped base wall 18 forms the base of chamber 31 and has a drain tube 21 to allow condensate from the waste gas to drain on to a wall 60 which also collects condensate from the waste gas entering through inlet 43. The condensate is removed by operating either manually or automatically a cock 44. Inlet pipe 43 extends tangentially of member 10.  Make-up gas may be introduced via an inlet 66 and pilot burners 42 ignite gas from the flare tip 51. A maintenance platform 48 is reached by a ladder 49.

Title: Improvements in or relating to electrical transmission networks
Inventor: CAMPBELL CHARLES FRANCIS
IPC: H03H7/01
Filed: 1953-05-06
Abstract: 738,523. Impedance networks. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. May 5, 1954 [May 6, 1953], No. 12651/53. Class 40 (8). A method of neutralizing stray capacitances in a network, e.g. a band-pass filter, of conventionally derived form, consists in modifying the values of capacitances in the network to absorb adjacent stray capacitances and substituting equivalent sections for such capacitative elements in the original network as are incapable of absorbing adjacent stray capacitance, the equivalent sections being such as to provide capacitances which are capable of modification by the adjacent stray capacitances. The stray capacitances are represented in broken lines in Fig. 1 which shows a conventionally derived band-pass filter. Capacitances C3 and C5 are absorbed by modifying the values of C8 and C9. Since there is no convenient shunt capacitance to absorb C4, the resonant circuits L10, C10; L11, C11 are each transformed according to a method described by T. E. Shea in "Transmission Networks and Wave Filters," D. Van Nostrand Co., 1929, pp. 325-334 and the equivalent sections of Fig. 2 obtained. The transformations also result in the two transformers TR1, TR2 which accommodate changes in impedance. By adjusting L15, L16, L17, C15, C16 and C17 transformers TR1 and TR2 can be combined to leave a single transformer TR3, Fig. 3. One of either pair of inductors L13, L14; L16, L17 will be negative and if the transformation ratios are correctly chosen L14 and the modified L16 being equivalent and of opposite sign can be eliminated. C14 and the modified C16 are combined with C4 to leave a single real capacitor C18, Fig. 3. The network, after transformation of the centre section, would be as shown in Fig. 3, in which C3, C4, C5 appear as absorbed in C22, C18, C20 and L15, C15; L17, C17 appear as L19, C19; L20; C20. Stray capacitances C2, C6 are absorbed by making similar transformations of C25, C26 to produce sections comprising capacitances and transformers. The shunt capacitances of these sections are modified to absorb C2, C6 and the transformers combined with each other to form a single transformer which, in the final circuit (Fig. 4, not shown), is combined with the transformer TR3. The pairs of resonant circuits L8, C22; L13, C13 and L20, C20; L9, C9, after modification, are combined to form a single pair of resonant circuits. It may be possible to arrange for the final transformation ratio to be unity, when the single remaining transformer could be eliminated. The whole of the transformation is completed before adjustment of shunt capacitances to absorb stray capacitances is made. Terminal stray capacitances may be reduced in known manner by increasing the values of L1, L2.

[Also in Division F4] Pure water is produced from brackish water by spraying it through rotary atomizer 32 into a stream of air flowing up through chamber 17 which is maintained warm by coil 18; some of the water vaporizes into the air, and the moisture-laden air, after passing through demister 28, is blown by fan 29 down into annular chamber 19 where it is cooled by coil 20 so that the water-vapour condenses yielding pure water, which is withdrawn through outlet 26. The air, reaching the bottom of chamber 19, is recirculated to chamber 17. The cylindrical wall 16, between the two chambers, is made of insulating-material. Coils 18 and 20 form part of a circuit which contains a refrigerant, and includes a compressor 41. Coil 20 is maintained at about 100 ‹F. by the vaporization of the liquid refrigerant and the vapours, after being compressed in compressor 41, flow into coil 18 where they condense at about 140 ‹F. The liquid refrigerant then flows back to coil 20 via restriction 42. Brackish water-to-betreated is introduced into well 14 via inlet 27; and some of the water is drawn up from the well into the hollow shaft 31, which drives fan 29 and atomizer 32. The water flows out of the ports 35 in shaft 31, and is atomized by blades 36. Excess water is drained out of well 14 via outlet 44. An apparatus is also described in which the product water is "Pasteurized", i.e. raised to a temperature of 140-212 ‹F., by heat-exchange with hot refrigerant. The feed water is preheated by heat-exchange with (i) the "Pasteurized" product water, and (ii) the air stream in chamber 19; and the rate of flow of the feed-water is automatically controlled by a valve to maintain the temperature of chamber 17 substantially constant. On-off electrical switches are incorporated in the apparatus so that the compressor and the fan are switched on or off in response to the level or temperature of the pure water in the storage tank. The refrigerant cycle may be replaced by an electric circuit having hot junctions disposed in the heating chamber and cold junctions disposed in the cooling chamber. It is also stated that the heating and cooling may be effected by a compression-expansion cycle of the circulating air. An apparatus is described in which the heating coil is supplied with hot gases from a burner, and the circulating air is blown towards the heating coil by a rotary impeller. The moisture-laden air is cooled in heat-exchange with streams of air at ambient temperature.
