[Also in Group XII] A gas turbine comprises a rotor disc with a combustion chamber formed inwardly and extending around its outer edge, discharge nozzles from the combustion chamber and air passages in the disc, for supplying air to the combustion chamber, which extend over the combustion chamber walls to cool them. The gas turbine comprises a rotor 11, Figs: 2 and 3, mounted in bearings 13, 14, consisting of an inner section 15 made of titanium or high strength steel and two outer sections 17 of a heat-resisting metal such as a stainless steel alloy. Air or an airfuel mixture entering at 33 is compressed by vanes 20 and vanes 23 and supplied to an annular space 25 which communicates with the combustion chamber 21 through a series of vanes 26. The combustion chamber discharges through a number of nozzles defined by the vanes 27 arranged so as to cause the disc to rotate. Short auxiliary vanes may be placed between the vanes 20 at the periphery of the disc to prevent circulation in the channels between the vanes. A ring 29, made in segments, is provided to define the annular space 25. To utilize the energy in the exhaust gases diffuser blades 32 are provided in a casing 30 mounted in spaced relation to the shroud 18 of the vanes 20. The casing 30 may be allowed to rotate and thus form a power turbine. If desired, the rotor 11 may be arranged to discharge axially into an axial flow power turbine. Fuel may be mixed with the entering air or may be supplied separately in liquid or vapour form through ducts in the rotor disc. Ignition may be by sparking plug or hot wire or the temperature of the air passing through the vanes 23 may be such as to cause automatic ignition. In the gas turbine plant, Fig. 8, the turbine 35 is of the type described. This turbine drives through a shaft 37 a compressor 36 which supplies air to the turbine through a conduit 40 and also air to cooling fins 42. This cooling air is mixed with the exhaust of the turbine 35 and passed to the power turbine 44.

Filed: 1934-01-12
Abstract: 410,714. Regulating compressors. SULZER FRERES SOC. ANON. Winterthur, Switzerland. Jan. 12, 1934, Nos. 1237 and 1238. Convention dates, Jan. 14 and Feb. 25. [Class 8 (i).] The clearance of a compressor is adjusted in accordance, e.g. with the common pressure in the suction pipe and crank case, by movement of a piston 4 which adjusts the space in its cylinder 3 communicating with the compression space and also controls the opening in succession of ports 6, 6<a>, 6b controlling auxiliary clearance spaces. Liquid is pumped from the crank case through valved pipes 9, 10 to the two sides of a piston 7 integral with piston 4, and these sides are also connected through pipes 15, 16 with the casing of a valve 17 in a chamber 18 under the pressure in the crank casing with which it communicates through a pipe 45. Rise of this pressure raises a bellows 20 which lifts a lever 19 and the valve 17 allowing liquid to flow through pipe 16 and down tubular valve 17 to the chamber. The consequent fall of the pistons 4, 7 raises a ported sleeve 24 through lever 27 and again cuts the flow off, leaving the pistons locked in the new position by the pressure of liquid. In a compound compressor with the first stage controlled as above, the piston rod 26 actuating the lever 27 may also actuate a valve to allow liquid to flow to a piston controlling second stage clearance valves.
