Abstract: 744,300. Impedance networks. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 23, 1953 [Aug. 9, 1952], No. 20087/52. Class 40 (8). To obtain an effective transfer and good matching between a source of signals and a load over a wide band of frequencies, a network is so dimensioned that if the reflection coefficient at the input of the network and the square of the transfer admittance to the load are each expressed as a series in terms of the frequency w of the signal the coefficient of the first term (w<SP>2</SP>) of each of the series is zero. In Fig. 1 signals from a source 2 are fed by a cable having a resistance R to a capacitive load 1 through a four-terminal network comprising an inductance 6 and two resistances 7, 8. If the inductance is L and the resistances R and aR respectively, then it is arranged that L = R2C, where C is the capacity of the load, and that a = 0.62. Modified networks for connection to a capacitive load through a transformer and to an inductive load are illustrated in Figs. 2 and 3, respectively (not shown).

Abstract: 354,508. Generating combustion products under pressure. LASLEY, R. E., Waukegan State Bank Building, Waukegan, Illinois, U.S.A. July 2, 1930, No. 20099. [Class 51 (i).] A gas turbine comprises a combustion chamber enclosed within a casing, through which air is fed by a compressor to the combustion chamber for effecting preheating, and an injector nozzle for the delivery of the combustion products together with further air to the turbine. In one form, the combustion chamber 1, Fig. 1, is surrounded by concentric annular chambers 8, 7 to which fuel from a carburetter 18 and air from a superheater 28 are supplied respectively, the fuel and air are mixed and discharged into the chamber 1 by co-operating injector and ejector nozzles 17, 16, Fig. 5, and the mixture is ignited by a spark-plug 66<1>, the combustion products being discharged through nozzles 14, 23, between which further air is drawn in, to the turbine 26. Air is supplied to the superheater by a compressor 33, driven by the turbine, part of the air passing from the superheater to the carburetter. The air inlet to the compressor is controlled by a hit-and-miss valve 54 connected with a centrifugal governor driven by the turbine. A pressure regulator 58 communicating with the outlet pipe 36 of the compressor is adapted to close the valve 54 and a valve 61 in the fuel pipe 22 in the event of a flexible coupling 39<1> in the turbine shaft 32 breaking. The nozzle 23 is controlled by a thermostat 48. In a second form, a plurality of combustion chambers 116, provided with fuel nozzles 119 and arcuate discharge nozzles 117, are enclosed in an air casing 112. At starting, a lever 157 of a fuel valve 124 is drawn back to engage a catch 165 thereby closing the switch 161 of an electric motor 144, which drives a blower 133 for supplying air through the casing 112 to the chambers 116, and rotates the valve through gearing 149, 150. Gasolene is then supplied in succession from a pump 130 through a pipe 129 and the passage 132 in the valve to the pipes 120 leading to the nozzles 119, and air is admitted simultaneously to the corresponding chamber 116 by a valve 137 on the extended stem 138 of the valve 124, the mixture being ignited by a sparkplug 118 controlled by a distributer 159 operated through the gearing 150, 160. A further valve 142 is operated simultaneously with the valve 137 to allow the incoming charge to force out any remaining burnt charge, which escapes through a pipe 141 to the atmosphere. The nozzles 117 project into correspondingly-shaped injector throats in a ring 167 so that further air is drawn in by the products of combustion. When sufficient pressure is built up by a compressor 111, driven by the turbine, a valve 163 opens to supply air to the casing 112, and, through a connecting-rod 164, operate a valve 171 to replace the gasolene by a fuel oil supply and release the catch 165. The motor 144 is thereby stopped and the valves 124, 137, 140 moved into an open position so that all the chambers 116 operate continuously.
