Title: Improvements in or relating to gas producers operating in conjunction with multi-stage gas turbine plants
IPC: F02C3/28
Filed: 1946-02-27
Abstract: 620,401. Gas-turbines. AKT.-GES BROWN, BOVERI, &CIE. Feb. 27, 1946, No. 6081. Convention date, Feb. 27, 1945. [Class 110(iii)] In a multi-stage gas turbine plant all the combustion gas and combustible gas required for driving the turbine or turbines and for re-heating the driving medium is produced in one or more gas producers 1 at the highest pressure reached in the plant. The various gas streams are taken for different heights up the producer shaft 1. Fig. 1 shows one arrangement in which compressed air enters at 2 and passes upwards through a bed of solid fuel 3, preferably coal. Combustible gas leaves through ports 6 and line 8 leading to an intermediate combustion chamber 9, and may pass through a turbine 10 on the way. Alternatively, line 8 may lead to different stages in the high-pressure turbine 13 to maintain an isothermal expansion therein. The rest of the gas stream passes through the coal bed and combustion gases, combined with air admitted through a port 11, leave through an outlet 12 leading to the turbine 13. Gases from the chamber 9 pass to a low-pressure turbine 14. In Fig. 2 high temperature gases leave through ports 15 and are mixed with compressed air entering at 16 from a pre-heater and are led to the turbine 13. A mixing device 17 is provided. Combustible gases leave the top of the producer shaft and pass to the combustion or re-heater chamber 9, direct or through a turbine 10. Dust may be extracted from the gases when passing at low velocity through the upper layers of fuel, or when passing from the device 17 to a chamber 7. Gas passing through ports 6 may carry dust with it, and may be led to a turbine provided with protective means against erosion or to a dust separator.

Filed: 1967-02-10
Abstract: 1,156,333. Magnetostrictive apparatus; gramophone pick-ups. STANDARD TELEPHONES & CABLES Ltd. 10 Feb., 1967, No. 6512/67. Headings H3U and H4J. A magnetostriction device comprises, Fig. 2, a T-shaped substrate, e.g. of glass, coated on one surface with a film 6 of magnetostrictive material, e.g. iron or nickel, to form a reed member. The film 6 is cut away by strips 7, 8, 9 and has contact areas 10, 11 deposited thereupon connected to terminals, whereby an electric current passing between the terminals is caused to take a meandering path 12. The current induces a strain in the film 6 causing the reed to vibrate in flexure at the frequency of the electric signal. In an alternative use of the reed member as a strain gauge, a static bias current is applied between the terminals or remanence may be used. The reed member may be caused to vibrate in the longitudinal mode by exciting it at the longitudinal frequency or by applying a cut-away film, similar to the film 6, on the other surface of the substrate, the electric signal being passed through both films. In another embodiment (not shown), a cylindrical substrate is provided with a helical film of magnetostrictive material to induce torsional vibrations. To reduce skin effect at high frequencies the magnetostrictive film may be coated with low resistance material, e.g. copper or gold. A further magnetostrictive film may be deposited on the low resistance coating. In another embodiment, Fig. 4A, relating to an electromechanical bandpass ladder filter, the magnetostrictive film 16 is coated on a rectangular flexible insulating substrate. Six windows 19 and two windows 20 are cut out from this assembly to form a coupling element 39 and four resonator elements 40 and to provide locations for input and output magnetostriction devices 41, 42 similar to the device shown in Fig. 2. Each device is formed by the removal of strips 23 ... 26 of the film 16 to provide two isolated film regions 21, 22 to which input and output terminals 27, 28 are connected. The resonator elements 40 form two rows, the two elements of each row being coupled to each other and to the device 41 or 42 of that row by the element 39. In another embodiment of a filter (Fig. 5, not shown), twelve windows are cut out from the film and substrate assembly to provide two transmission paths between the input and output magnetostriction devices and the filter has attenuation peaks in the upper and lower stop bands.
