Abstract: 845,202. Steam and gas turbine power plant. GENERAL ELECTRIC CO. Nov. 27, 1956 [Nov. 29, 1955], No. 36264/56. Class 110 (3). A combined gas and steam turbine plant comprising a combustion chamber feeding the gas turbine and a steam turbine with at least two pressure stages with reheating between them has a boiler and reheater for the steam turbine situated in the combustion chamber with the boiler nearer the outlet and the reheater nearer the burners respectively. A compressor 1 supplies combustion air to a combustion chamber 2 feeding a turbine 3 driving the compressor 1 and an electric generator 9. The exhaust of the turbine 3 heats the feed water from a boiler feed pump 5 in a heat exchanger 4. The feed water is then heated in a boiler 2a and then supplied to the inlet of the steam turbine 6. After expansion in the high-pressure stage, the steam is reheated in the coil 2b and then fed to the low-pressure stage of the turbine 6. During starting, the turbine 6 is by-passed by the conduit 6g controlled by valve 6f. Control and intercept valves 6b, 6e may also be provided. The turbine 6 may drive an electrical generator 10. The gas turbine 3 may be arranged to drive also the boiler feed pump 5.

[Class 40 (iv).] An electric amplifier comprises an anode, a cathode with an electronically active layer or body situated between them and associated with a control grid, and an electron-carrying material of any desired resistance interposed between the active layer and the anode. The amplifier is used in the same way as a thermionic valve amplifier and may have more than one grid. In the solid type shown in Fig. 1, the amplifier comprises a metal cathode a, an active layer b, an electron-carrying layer c of high resistance, and a metal anode d. The grid e may be arranged in or on the surface of active layer b, e.g. the grid may be coated with an active paste or by electro-deposition. The active layer may comprise copper oxide or lead sulphide, and the electron-carrier may be an oxide, iodide, proto-iodide in solid or compressed powder form. Two grids may be inserted in an active layer, or the upper and lower surfaces of the layer may each have a grid associated with them, a further layer of electron carrier being interposed between the lower grid and the cathode. The amplifier may be enclosed in an insulated container. In the electrolytic form shown in Fig. 2, an active body k connected to the cathode terminal is placed in an electrolyte i, and the containing vessel l constitutes the anode. The grid e, as shown, is placed in the electrolyte some distance from the body k, but it may be close to or on the body k. The electrolyte, which may be in paste form, may consist of acids, caustic potash or salts such as are used in electrolytic rectifiers. Two or more grids may be used by separating them by porous pots containing different electrolytes.

Abstract: 1,093,618. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Dec. 2, 1965 [Dec. 8, 1964], No. 36813/64. Heading G6C. In a nuclear reactor fuel element the fuel is porous and vaporizes the liquid coolant flowing through it. Liquid sodium or water may be employed as the coolant and in the latter ease superheated steam is produced. The porosity of the fuel increases towards the surface from which the vapour issues. In one embodiment, the vaporizing and superheating zones are separated by a heat insulation layer to prevent the attainment of a uniform temperature throughout the zones. The insulation layer may be replaced by a space. The element is cylindrical with a channel following the longitudinal axis and the coolant may flow radially through the fuel either inwards or outwards. The element is suitable for use in power plant comprising cascaded sodium, mercury and water circuits or sodium, gas and water circuits where the gas is employed in a magnetohydrodynamic generator.

Abstract: 903,640. Mixer/settler apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 14, 1960 [Nov. 2, 1959], No. 37180/59. Class 46. A pulsed mixer/settler is connected with the inlet branches of a series of columns 2 fitted to a common sump tank 1. The pulsing system is adapted to increase and decrease the pressure of air in two manifolds in oppositely phased relationship and may be a twin piston and cylinder arrangement as more fully set forth in Specification 831,383. Water is fed continuously through a common pipe to the nozzles 18 which disperse the water in a spray over the packed colmuns 2 towards the point of collection in the sump tank 1. This sprayed dispersion of water constitutes a pervious contamination barrier between the inlet and outlet branches in each of the columns 2 so that any radioactive contaminants, which may escape from the mixer settler through the mixer tubes as fine spray or in gaseous form, are absorbed by the water and hence removed to the collection point. This water is recirculated until it reaches a predetermined contamination level.
