IPC: C01B3/38
Filed: 1968-05-03
Abstract: 1,271,721. Methane-containing gases. GAS COUNCIL. 21 April, 1969 [3 May, 1968], No. 21186/68. Heading C5E. A process for making a gas rich in methane comprises catalytically steam-reforming a preheated mixture of steam and a paraffinic hydrocarbon feed and catalytically reacting the product gas to increase its CH 4  content, both catalyst stages being cooled by heat exchangers. The process is similar :in details to the one described in Specification 1,265,481, but omits the step of introducing a further -quantity of one at least of the reactants between the stages, and no reference is made to the use of an externally fired tubular reformer in the first stage. Internal heat exchangers are preferably used, but the catalyst may be in tubes surrounded by the cooling space, or the whole catalyst bed may be jacketed. In the first stage, the inlet portion of the catalyst may lie outside the cooling zone. Cooling is by water which is passed in series through a heat exchanger for the final gas, and then through the second and first catalyst stages, steam so raised being optionally used as a reactant. H 2  may be withdrawn from between the stages to desulphurize the feed.

Abstract: 408,849. Thermally-actuated valves. HAMMOND, M. C., 78, Main Street, Bradford, Pennsylvania, U.S.A. July 28, 1933, No. 21266. [Class 135.] A pair of thermal elements 36, 40, the former being affected by the temperature of a bearing and the latter by the atmospheric temperature act upon a valve 31 to control the flow of lubricant. One end of the element 36 is connected to a drum 18 and the other end terminates in an arm 37 which is connected by a link 48 to a lever 47 pivoted at 46. A part of the lever 47 forms a drum 38 to which one end of the member 40 is secured. The free end 41 of the member 40 forks a nut 42 screwed upon the stem 32 of the valve 31. The members 36, 18, and 40, 38, are filled with glycerine or the like and sodium chloride or the like respectively. In operation the movement of the member 36 due to a rise in the temperature of the bearing 26 rocks the lever 47 and tends to open the valve 31. Expansion of the member 40 due to a rise in the atmospheric temperature tends to close the valve. The drums 18, 38, are co-ordinated so that at high temperatures the valve opening is less than at low temperatures. The valve 31 is supplied from a lubricant well 13 which is fed from a reservoir 14 on the bird-fountain principle. The reservoir 14 has a level gauge 17 and the valve delivers to a sight-feed tube 28.

Title: Improvements in or relating to prime movers for aeroplanes or the like
IPC: F02C3/08
Filed: 1945-08-22
Abstract: 597,261. Gas turbines ; jet-propulsion of aircraft. LYSHOLM, A. Aug. 22, 1945, No. 21493. Convention date, Sept. 1, 1944. [Classes 110 (i) and 110 (iii)] In controlling the operation of a gas turbine plant for the jet-propulsion of aircraft, with or without an associated airscrew, compressed air is bled from before the combustion chamber, or, between the stages of a multi-stage compressor, and is discharged into the atmosphere through either forwardly or rearwardly-directed nozzles to diminish or augment the propulsive force of the main propulsive jet. Exhaust gases from the turbine, also, may be discharged through forwardly directed nozzles. These controls are associated with fuel regulation and a device for varying the area of the main propulsion jet. In the plant shown in Fig. 1, a multi-stage turbine 27 drives a multi-stage compressor through a speed increasing epicyclic gear 54. The compressor comprises an axial flow stage with fixed blades 12 and running blades 10 and a centrifugal stage with axial entry blades 14 and centrifugal blades 13. Air from the compressor is discharged into a chamber 17 from which it passes through nozzles 22 into a single annular combustion chamber 3. Fuel is admitted through pipes 23. Air from the chamber 17 may be discharged directly to the atmosphere through forwardly directed nozzles 18 or rearwardly directed nozzles 19. The turbine exhaust goes to a propulsion jet 29, the effective area of which can be varied by means of a cone 32 which can be moved axially by means of a screwed spindle 36 and worm-gear 34. Exhaust gases may also be exhausted through openings 47 governed by flap valves 48. The discharge from the volute 15 of the compressor is by way of tangential conduits 16, Fig. 4, which terminate in right-angle turns. Alternating with these conduits, there may be other similar conduits 60 which project through the nacelle of the plan and discharge air to the atmosphere rearwardly. In another plant, the compressor having two centrifugal stages is driven at turbine speed and an airscrew is driven through a speed-reduction epicyclic gear. Flap controlled orifices permit the discharge of air to the atmosphere from the interstage space and frc m the space between the compressor and the combustion chamber either in a forward or a rearward direction. The positions of the controls are given for five working conditions, namely, two stand-by conditions, idling, cruising speed and full speed. Change from one set of positions to another may be effected by one control lever, or, two levers, one for stand-by and one for load conditions. Additional independent adjustments are provided. Slowly cha iging conditions may be met by fuel and air bleed regulation only and to provide for this the propulsion jet area control transmission includes a hydraulic leak device which is effective to transmit only when the movement of the control lever is rapid.
