Patent GB-960739-A (GB)
Title: Gas-analyzer device and method
IPC: G01N7/00
Filed: 1963-04-12
Abstract: 960,739. Gas analysis. WESTINGHOUSE ELECTRIC CORPORATION. April 12, 1962 [April 28, 1961], No. 14148/62. Heading G1B. The volumetric percentage of non-condensable gaseous contaminants in a readily condensable gas is determined by submitting the impure gas to slow compression, e.g. by increasing the pressure in 5 p.s.i. increments at 10 second intervals, and noting the pressure P2 at which liquefaction just begins. The required percentage is then deduced by means of graphs (exemplified in the Specification) obtained by plotting (P2 - P1), where P1 is the pressure of the pure saturated gas, against temperature for a series of gas mixtures of known composition. The method can be used to determine the percentage of air in sulphur hexafluoride gas from an electric circuit interrupter of the gas blast type. The interrupter 1 is connected via pipe 35 to the testing apparatus which comprises a chamber 12 of fixed volume, and a chamber 13 the volume of which can be varied by piston 14. The two chambers are separated by a metallic block 21 which has a passage 19 for connecting chamber 12 to a cylinder 31 of pure liquid SF6, and a passage 20 for introducing contaminated SF6 gas from the interrupter into chamber 13. The two chambers are surrounded by annular water-chambers 43 and 54 which communicate via holes 55. Pure liquid SF6 is introduced into chamber 12 until the liquid occupies about 40% of the volume of the chamber. The saturation pressure P1 of the pure gas in chamber 12 is measured on gauge 28, and the temperature of the surrounding water-chamber is measured on thermometer 51. With piston 14 in the position shown by the dotted lines, chamber 13 is evacuated by pump 33. Valve 32 is then closed, and the gas to be tested is introduced into chamber 13 by opening valve 34. After closing valve 34, the piston 14 is slowly moved forward, by means of crank 16, until the gas in chamber 13 just begins to liquefy, the presence of liquid being noted visually through sight-glass 38. By fine adjustment of the crank 16, the piston can be so positioned that the point at which liquefaction of the gas begins can be determined accurately. The pressure P2 in chamber 13 is then read on gauge 28. The apparatus can also be used to measure the volumetric percentage of gaseous contaminants in the following gases: selenium hexafluoride, perfluoropropane, sulphur dioxide. Specification 885, 932 is referred to.

Filed: 1970-03-24
Abstract: 1299622 Carbonating beverages MOJONNIER BROS CO 24 March 1970 [24 March 1969] 14257/70 Heading B1C A beverage is subjected to two stages of carbonation to yield a uniformly carbonated product, the first stage of carbonation being effected on a beverage liquid delivered at constant pressure to a line 64 controlled by a restriction 58, the pressure in the line remaining substantially constant. Water is admitted to a unit 12 through an inlet 18 under control of a valve 19 operated by a float 20 in dependence on the level of liquid in the unit 12, passes into an evacuated chamber 14 and cascades over heating plates 24, de-aerating plates 26 and cooling plates 28. The cooled, de-aerated water is pumped to a unit 46 where it is mixed with a flavouring additive. The flavoured liquid collects in a reservoir 54 and is impelled by a constant pressure pump 60 into the line 64 where introduction of carbon dioxide from the unit 70 effects primary carbonation of the liquid. The carbonated liquid flows into the secondary carbonating unit 72 under control of a restriction valve 58 controlled by a float 56 in dependence on the liquid level in the reservoir 54. In the unit 72, the liquid cascades over cooled plates 94 in an atmosphere of carbon dioxide so that it may take up or give off gas according to the conditions, and emerge from the unit 72 carbonated to the desired degree, for transfer via a conduit 76, and pump 79 to a bowl 74 of a filling apparatus, under control of a valve 78 operated by a float 80. Carbon dioxide is supplied to the unit 72 by a unit 100 having a presure relief valve 104. The gas pressure in both units 70 and 72 is adjustable. The unit 70 may be a cooler carbonator similar to the unit 72.
Patent GB-889424-A (GB)
Title: Combination of a nuclear power plant with a separately fired superheater
IPC: G21D5/16
Filed: 1958-05-05
Abstract: 889,424. Nuclear power plants. MARGUERRE F. May 5 1958 [May 3, 1957; Aug. 24, 1957], No. 14272/58. Class 39(4) [Also in Group XIII] To match the constant output of a nuclear reactor to the varying load of an electrical grid, an externally fired superheater is used in conjunction with tegenerative (or " drop ") accumulators, in addition to the usual feed water displacement accumulators. Steam from the reactor heat exchanger is superheated by the upstream superheater gases and fed to a turbine. Steam for the accumulators is bled from the turbine after partial expansion and passed through a superheat-recuperator to the regenerative accumulators. On discharge it passes through the superheater waste gases before entering the turbine at intermediate stages. Any remaining heat in the superheater gases is used to supplement the preheater for the turbine condensate. To match the accumulator steam temperature to that of the input points and to divert heat to the preheater when the accumulator superheater is not needed the amounts of heat reaching each part of the superheater can be varied. More than one accumulator may be used, operating at different pressures and on different turbine tapping points. This reduces the size of the tapping points. A separate turbine may be used for discharging the accumulators: In discharge, hot water flows from the regenerative accumulator 21 through a valve 23 to an expansion vessel 24 and is returned to the accumulator. Steam from the expansion vessel goes to the turbine 29 which acts as an energy-recovering throttle device, and is controlled by valve 23 only. The state of discharge of the accumulator is known from its average temperature. For charging, steam is bled from the main turbine through valve 31a. Water flows from the accumulator through line 26 and pump 32 to the expansion vessel, and is returned by pump 25 through lines 34 and 22 to the accumulator. The flow of water is thermostatically controlled to give the correct full-charge temperature. The superheater would be inserted in line 27. The turbine may have a valve to by-pass some rows of blades for high-load working. The condensate may be preheated in the main turbine circuit before re-circulation. Charging may also be done by putting a surface preheater in line 31.
