Title: Device for the application of periodic explosions of gaseous explosive mixtures or of the periodical stoppage of gaseous fluids under pressure to the operation of turbines and other energy recovering apparatus
IPC: F23C15/00
Filed: 1922-10-13
Abstract: 188,642. Laudet, G. C. A. Nov. 7, 1921. [Convention date]. Percussive tools.-Resonating chambers containing fluid, in which nodes and antinodes are produced in a manner similar to the sounding of an organ pipe, are used as elements in prime-movers. In the example shown in Fig. 7, a V-shaped pipe 21, 22 is sounded by the passage of the products of explosions through the throat 20 and an impulse turbine wheel 25 placed at an antinode in the pipe is rotated by means of the axial oscillations of the fluid in the pipe at that place. In Fig. 4, a pipe is shown which is excited by the periodic admission of a pressure fluid by way of a single inlet valve I or a valve at each end, the valves being operated in the proper phase relation. The action can also be assisted by the timed opening of valves at the nodes which communicate with suction apparatus. Gases introduced into the pipes do not travel beyond the first node and may be allowed to escape by an opening at the first anti-node. Cutting-tools and connecting-rod or ratchet mechanisms may be operated by the alternations of pressure obtaining at the nodes. Several examples of the application to turbines are given.

Abstract: 756,687. Gas turbine plant; stop-gear. ENGLISH ELECTRIC CO., Ltd. Oct. 8, 1954 [Oct. 14, 1953], No. 28324/53. Classes 110(3) and 122(4) [Also in Group XI] A gas turbine fuel system comprising an engine driven fuel pump supplying fuel to spill burners wherein the spill pressure is automatically controlled so as to keep the flow in the spill line constant, has the pressure of the fuel supplied to the burners controlled by a valve in the burner inlet line actuated either directly or by remote control and an automatic pressure reducing valve and a restriction responsive to gas turbine inlet temperature arranged in series in the spill line. Fuel from the tank 11 arranged below the level of the burners 7 is supplied to the inlet of an engine driven pump 2 having in its discharge conduit 3 a relief valve 4. The conduit 3 leads to a manual control valve 6 which contains a throttle valve 16 and a shut down valve 26. The valve 26 connects the discharge to the suction side of the pump. The control valve 6 is connected to the burners 7 through a trip valve 27 responsive to lubricating oil failure, a loading valve 18 and filters 19. As shown the valve 27 is loaded in the closing direction by the pressure of the lubricating oil. The loading valve 18 contains a capsule 28 which, is partly filled with liquid to safeguard the capsule when the fuel pressure is high. This valve is arranged to open at a given pressure but, once lifted, the fuel pressure acting on the capsule 28 keeps the valve open until the pressure drops to a lower value than that which is required to open the valve. The spill lines 8 from the burners 7 are connected to an automatic reducing valve 9 which maintains the pressure before the restrictor 10 constant. The valve 9 is adjustable so that this pressure and in consequence the flow through the restrictor may be pre-selected. The restrictor 10 has valve members 10<SP>1</SP>, 10<SP>11</SP>, controlled through lines 110, 111 so that when the temperature in the combustion chambers exceeds a predetermined value the area of the restrictor 10 is increased and the spill flow also increased. When the gas turbine plant has more than one combustion chamber a valve member 10<SP>1</SP>, 10<SP>11</SP> may be provided for each chamber. In a modification, separate reducing valves 9 and restrictors 10 may be provided for each combustion chamber. If the fuel is aerated the spill pipe may be connected to the fuel tank 11 instead of, as shown to the intake of the fuel pump 2.

Title: Process for purifying gases from organically combined sulphur
IPC: C10K1/34
Filed: 1927-10-25
Abstract: 282,634. Fischer, F. Dec. 24, 1926, [Convention date]. Catalytic agents, preparation of.-Gases such as water-gas, which may be first freed from sulphuretted hydrogen, are treated for the removal of other sulphur compounds by means of a catalyst consisting of a precious metal of the first group of the periodic system particularly silver, which convert the sulphur compounds in presence of hydrogen to sulphuretted hydrogen but cause no other change in the composition of the gas. The sulphuretted hydrogen is then removed in the usual manner. In an example asbestos fibres are impregnated with silver nitrate solution, dried, and heated to red heat to produce a catalyst containing silver oxide. The water-gas which has been freed from sulphuretted hydrogen is passed over this catalyst at 200-300‹ C. and then treated to remove the sulphuretted hydrogen produced. The Specification as open to inspection under Sect. 91 (3) (a) includes the, use of precious metals such as silver or gold. This subjectmatter does not appear in the Specification as accepted.
