Title: Improvements in regulating devices for gas turbine engines operating by controlling the fuel supply thereto
IPC: F02C9/16
Filed: 1955-06-10
Abstract: 784,690. Gas-turbine plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 10, 1955 [Jun 11, 1954], No. 16802/55. Class 110 (3). [Also in Group XXIX] In a device for regulating a gasturbine engine by maintaining the fuel supply thereto within the limits of extinction and mismatching for every running condition, the device comprising a member such as a regulator piston 2, movable to control the fuel and associated with stops, for example levers 18, 19, limiting the displacement of the member so as to allow an acceleration up to the upper limit prescribed by the stop and similarly a retardation driven to the lower limit, the position of the stops is automatically adjusted in response to the delivery pressure of the engine compressor 5b. The latter is conected to a chamber 5 in which are manometric capsules 4, the impulses of which are applied to a slide valve 6 movable in a piston 9 and controlling orifices 7, 8 of chambers 11, 14 situated on opposite sides of the piston; pressure oil flows to ports 10 and 16 by way of ducts 9b in circuit with the engine hydraulic system. Expansion of the capsules 4 due to a reduction in air pressure moves the valve 6 to the right against a spring 17 thus enabling oil to enter the chamber 11 via port 10 and orifice 7, chamber 14 being simultaneously exhausted through orifice 8 and a duct 15 so that the piston 9 travels to the right until the lands 12 and 13 again mask the orifices 7 and 8. An increase in air pressure similarly brings about a leftward traverse of the valve and piston. The stop levers 18, 19 which are connected to the piston 9 and joined by an adjustable rod 20, co-operate with a rod 2e of the regulator 2 which is connected by a lever 1a to a servo-piston 1. An increase in engine speed, for example, is effected by rightward movement of a lever 23 and hence through a cam 24 increases the thrust of a spring 25, which thrust was previously balanced by that of the governor weights 26, whereupon a valve 27 admits oil to one side of the servo-piston 1 and exhausts the other side thereof to translate the regulator 2 and increase the fuel supply to the burners 35 until the rod contacts the stop lever 18; any further increase in speed is controlled by the piston 9. The valve 27 returns to the position shown when the thrust of the weights and spring 25 are again in equilibrium. In a modification, the capsules act on the fuel valve without the interposition of a servo. motor.

Title: Process for separating carbon dioxide from gas mixtures
IPC: C01B32/50
Filed: 1954-06-11
Abstract: Carbon dioxide is separated from a gaseous mixture containing one or more C1-C7 aliphatic hydrocarbons, e.g. a Fischer-Tropsch synthesis tail gas by contacting the mixture in countercurrent flow with an aqueous scrubbing liquor at a temperature of 100-140 DEG  C. and at a pressure such that the carbon dioxide partial pressure is greater than 1 atmos. preferably greater than 4 atmos., and thereafter regenerating the scrubbing liquor at atmospheric pressure and at a temperature not substantially lower than that used in the scrubbing zone and not higher than 140 DEG  C.  The scrubbing liquor may contain 15-30 per cent of Na2Co3, 30-40 per cent of K2Co3 or 30-50 per cent of mono-, di, or tri-ethanolamine.  The temperature in the scrubbing zone may be maintained by introducing steam in an amount equal to that escaping from the scrubbing zone in the effluent gas. Alternatively, indirect heating may be employed together with the continuous introduction of water, which may be water condensed from the effluent gas, to the scrubbing zone.  The temperature in the regeneration zone may be similarly maintained.  The heat of the effluent gases from the absorption and regeneration zones may be utilized for heating the entrant gas by means of heat exchangers.

Patent GB-176225-A (GB)
Abstract: 176,225. Hassler, E. H. H. Jan. 31, 1921. Brush-holders.-A brush-holder consists of a fixed support member A, forming the upward continuation of one side of a brush-box B, and a movable abutment member H. The abutment member carries an arm F which passes through a slot C in the support A. This arm has a jaw E engaging the back of the support member L and a jaw G on the member H engages notches J on the front. In order to allow the jaw E to pass to the back, a cross aperture KK<1> is out on the fixed support, at right-angles to the slot C. A spring D attached to a projection L on the abutment piece carries at its lower end a button M pressing into a recess on the brush B<1>. The line of action of the spring is such as to cause the abutment member H to turn about the fulcrum G until the jaw E grips the support member at the back. To prevent the arm F from slipping out accidentally, the aperture KK<1> is made to slope upwards from front to bach; alternately, the jaw E and slot KK<1> may be made unsymmetrical with respect to each other, or other devices may be employed, such as the provision of a clip-shaped spring N pressing into grooves O, O<1> at the sides of the openings KK<1>.

Abstract: 919,451. Preventing corrosion. SINCLAIR REFINING CO. May 20, 1960 [July 27, 1959], No. 17876/60. Class 123 (1). Corrosion of ships' tanks containing sea-water ballast or iron or steel storage tanks for impure water is reduced by adding to the seawater &c. a small amount of a mixture of a zinc salt such es the acetate, borate nitrate, sulphate and most of the halides and halates and a watersoluble arsenic compound such as the sodium potassium, ammonium and hydrogen arsenates and arsenites or some organic arsenic esters. A preferred mixture consists of equal weights of zinc chloride or sulphate and arsenic or arsenous acids, the mixture being added in the dry state or as a solution or suspension in water, preferably in amounts from 750 to 1250 p.p.m. The additive may also be used in conjunction with a galvanic or impressed current cathodic protection system when the anode consumption or current required is much reduced. When used in this manner less additive is required, from 15 to 75 p.p.m. of a mixture of one part of the arsenic compound to one to five parts of the zinc salt being adequate.

Abstract: 969,082. Gas cooling installations; removing dust generated in converters. BIRWELCO Ltd. July 10, 1963 [May 10, 1962], No. 17939/62. Headings F4B, F4K, F4S and F4X. In a method of cooling hot dust-laden gas emitted for example from a metallurgical converter, the primary cooling of the gases is achieved by recirculating a portion of the gases which have been subjected to secondary cooling and admixing said portion with the hot emitted gases prior to subjecting the latter to secondary cooling. In Fig. 1, dust-laden fumes at approximately 1000‹ C. from a converter 10 are received in a hood 11 and passed after primary cooling to approximately 500‹ C. at point 21 to a secondary cooler 13 where they are further cooled to 150‹ C. The secondary cooler may cool the fumes by passing the same through a tubular heat-exchanger for dissipation of heat to cooling water or the atmosphere or by means of a water spray. From the secondary cooler some of the gases pass directly to a cleaning plant through duct 16 while the remaining gases are used as a primary cooling agent at 21 for freshly-emitted gases, these remaining gases passing through ducts 17 and 20 under the action of a fan 18 and variable damper means 19. Alternatively, the primary cooling may take place in the hood 23 of Fig. 2, the hot gases being cooled therein by the secondary cooled gases which pass through the outer of two coaxial ducts 24 and 25 to mix with the hot gases in the hood, the secondary cooled gases being led into the hood initially between the hot gases and the hood wall. The admixed gases pass through the inner duct 25 to the secondary cooler.
