Abstract: 711,804. Gas turbine plant. SOC. D'ETUDES ET DE PARTICIPATIONS EAU, GAZ, ELECTRICITE, ENERGIE, SOC. ANON. July 3, 1951 [July 5, 1950], No. 15804/51. Class 110(3) [Also in Groups XXVII and XXIX] In a power plant in which a prime mover is driven by pressure gas supplied by a free-piston generator having its fuel supply controlled by a governor operated by the speed of the prime mover an emergency device is provided to stop the freepiston generator by acting upon the fuel injection pump thereof when the speed of the prime mover exceeds a predetermined value. Power gas from a free-piston generator flows through a reservoir 17 and conduit 16 to drive a gas turbine 18. The amount of fuel supplied to the power cylinder 1 of the free piston generator by a fuel injection pump 11, tappet driven direct from the compressor piston 5 through links 12, 13, 14 is controlled during normal running by an arm 15 actuated by a centrifugal governor 21 mounted on the gas turbine shaft 22. If the speed of the gas turbine exceeds a predetermined amount the masses 21a of the governor act on a rod 30a to open a spring-loaded valve 30 which allows compressed air from an outside source to flow through a pipe 29 to raise a piston 27 attached to the rod of the fuel injection pump 11 which is thereby rendered inoperative and the free piston generator stopped. Opening of the valve 30 also allows compressed air to flow through a conduit 29a and operate a piston 33 attached to the stem of a spring-loaded relief valve 31 which lifts and relieves the pressure in the reservoir 17 and conduit 16. Relief valves may also be provided in the compressor portion of the free piston generator. Further, a shutter which is controlled by the governor 21 and closed when the turbine exceeds its predetermined speed may be fitted in the inlet conduit 16.

Abstract: 615,719. Reciprocating pumps. TEXACO DEVELOPMENT CORPORATION. June 25, 1945, No. 16120. Convention date, June 29, 1944. [Class 102 (i)] A pump for forming and delivering a mixture of liquids comprises a plunger 12 formed with an inclined shoulder 38 controlling inlet ports to which the various liquids are supplied. In the construction shown in Fig. 2, two inlet ports 22, 24 are provided. On the downward stroke, the port 24 is opened first and the quantity of liquid entering the cylinder depends upon the suction developed in the cylinder, the size of the port and the pressure at which the liquid is supplied. Further movement of the plunger opens the port 24 which in the construction shown is of larger diameter and supplied with liquid at a higher pressure. Upon upward movement of the plunger the port 22 is closed and the mixture is discharged through valve 26; a valve 36 may be provided to prevent return through the port 24. In the construction shown, the amount of liquid passing through port 24 increases as the total quantity delivered increases. The pump may be used for mixing high and low value octane or cetane fuels. The shoulder 38 may have varying inclinations and may not open an inlet port at high or low deliveries. A recess in the plunger may be connected by bores to the working face of the plunger to end abruptly the delivery when the recess opens a spill port. Specification 615,724 is referred to.

Title: Improvements in or relating to the recovery of sulphur from hydrogen sulphide containing gases
Inventor: MARSH JOHN DAVID FRANCIS
IPC: C01B17/04
Filed: 1958-05-20
Abstract: Sulphur is produced by catalytically oxidising hydrogen sulphide to sulphur dioxide with air in at least 35% of a gas containing 1-5% of hydrogen sulphide, the amount of air employed being stoichiometrically equivalent to the hydrogen sulphide content of one third of the hydrogen sulphide-containing gas, admixing the oxidised gas with the remainder of the hydrogen sulphide-containing gas, and catalytically interacting the hydrogen sulphide and sulphur dioxide in the mixture to produce sulphur.  The hydrogen sulphide-containing gas may be produced in the regeneration of potash liquor employed in washing synthetic gas obtained from fuel oil.  The oxidation catalyst may be active carbon or zinc, iron, nickel or titanium sulphide.  The sulphide may be supported or activated alumina or corundum, and may be formed in situ.  A mixed or promoted catalyst may be employed. Oxidation may take place at 250-400 DEG C., and a space velocity of 1000 s.cu.ft./hr/cu.ft.  The sulphur-production catalyst may be activated alumina or titania, and the reaction temperature is preferably between the dew point of sulphur and 15 DEG C. above this temperature, e.g. 210 DEG C.  The sulphur may be removed in a ring-packed washer-cooler type condenser.  The remaining gas may be mixed with hot combustion gas containing excess oxygen from an oil or gas burner and passed over activated alumina or iron-bauxite at 350-400 DEG C., or nickel, copper, or copper-cadmium sulphate supported on activated alumina at a lower temperature. The resulting sulphur dioxide-containing gas may be passed in indirect heat exchange with the gases to be treated in each stage of the process. Specification 769,996 is referred to.

Title: A fuel control for a combustion chamber
Inventor: BILLMAN LOUIS STANLEY
IPC: F02K7/10
Filed: 1956-05-25
Abstract: 827,863. Jet propulsion plant. UNITED AIRCRAFT CORPORATION. May 25, 1956, No. 16221/56. Class 110 (3). [Also in Groups XII and XXIX] A ram jet has the combustion chamber divided into a pair of separate combustion spaces into one of which fuel is injected at a rate a fixed percentage greater than the rate at which the fuel is fed to the other combustion space so as to obtain different fuel to air ratios and means responsive to the difference in the resulting pressures in the combustion spaces for varying the rate at which fuel is supplied to the combustion chamber. The ram jet 10, Fig. 1, is divided into two complementary spaces A, B into which fuel is injected by nozzles 24, 26, respectively. The nozzles 24 inject into the space A more fuel than the nozzles 26 inject into the space B. This results in a pressure difference between the spaces A and B which changes sign as the fuel-air ratio passes through the stoichiometric condition. This pressure difference is used to control a regulator 20 which controls the fuel flow to the nozzles 24, 26. Variations in the pressure difference between the spaces A and B cause movement of the bellows 30 which actuate a valve 44 through a lever 36. Movement of the valve 44 will vary the pressure in the bellows 50 which pressures are slightly greater than the pressures in the chamber 52 due to the restriction shown. The resulting movements of the bellows 50 control the fuel flow regulating valve 58. An adjustable spring 64 is provided so that the regulator can be set at any desired fuel-air ratios. The inner central body 12 may carry the fuel and fuel-flow regulating mechanism. One set of fuel nozzles may be pilot nozzles.

Title: Improvements in or relating to power-transmission mechanism
IPC: B60T13/24
Filed: 1927-06-20
Abstract: 302,704. Monge, G. de. June 20, 1927. Fluid-pressure ;hand and foot actuation.- Relates to operating mechanism particularly for brakes comprising in a vacuum chamber 3 a valve 3p adapted to open against a spring when the pressure in the chamber becomes higher than atmosphere. This valve is of large diameter so as to respond to slight changes of pressure. A connection 4<m> is provided for actuating the brakes directly. The vacuum chamber is in the form of a bellows through which air is constantly drawn by the suction pipe of the engine of the vehicle by means of a pipe 8<a>. The air inlet is controlled by a valve 6 mounted in the fixed plate 3<c> of the bellows and connected to a floating lever 7 to which the foot pedal 2 and the connection 4<m> are attached. The movable end plate 3<a> of the bellows and the connection 4<m> are attached to a lever 4 connected to the brake mechanism 41. Movement of the valve to throttle the air inlet lowers the pressure in the bellows which contract and move the end plate 3<a>. The operation of the valve is also dependent on the position of the member 4 owing to the connection 4<m> and the floating lever 7. A spring 6<n> produces a reaction on the 'operator's foot. The valve is gradually tapering to produce a graduated control. If the power means lags behind the direct operation the consequent pressure produced in the bellows escapes by the valve 3P. The valve ti is stopped when the brake is released in such a position that a continuous subdued action of the power means is produced in order to take up the slack in the transmission. The pipe 8<a> to the engine may be throttled by baffles 9<k> provided with holes or by constricting the pipe. The end plates 3<a>, 8<c> of the bellows are provided with bosses to restrict the space therein. When the bellows are contracted they fold round these bosses. Stiffening metal rings 3<r> are provided.
