Abstract: 1,087,475. Detecting ice-formation electrically. ROSE MOUNT ENGINEERING CO, Oct. 12, 1965 [Nov.5, 1964J, No. 43254/65. Heading G1N. [Also in Division H4] Apparatus for detecting and indicating the formation of ice on e.g. an aircraft, comprises a protruding tube whose natural frequency of oscillation is varied by the ice forming on it, and is measured electrically. As shown (Fig. 1) a ferromagnetic tube 20 is centrally mounted in the end face 17 of a housing 10. The inner portion 20I is provided with coils 30, 31 connected in the tank circuit of an oscillator 40, and of co-operating with a magnet 32 to produce axial vibrations of the tube by magnetostrictive action. The oscillatory frequency is the natural frequency of oscillation of the tube in two parts with the point of mounting 18 in the end plate as a node. This frequency is indicated at FI, and energizes a tuned relay 70 to maintain contacts 74, 75, 76 open. When ice forms on the external portion 20E of the tube its vibration frequency changes, and is indicated at FI, and relay 70 drops to close the circuit for a heater 80 located in the exposed portion 20E. When the ice melts, the previous vibration frequency is restored, and the heater is again disconnected. The rate at which the heater is cyclically operated indicates the rate of icing. In modification - (a) the vibration frequency is compared with that of a reference oscillator mounted within the housing, thus automatically compensating for ambient temperature variations, (b) the feedback coil 31 may be mounted on the portion 20E of the tube but shielded from atmospheric conditions by a thin membrane brazed to the tube and the housing 10 Fig. 3 (not shown), (c) de-icing may be effected by increasing the power of the magnetostrictive action to produce violent vibrations sufficient to warm up the tube by its internal friction.

Title: Steam Turbine Starting of Gas Turbine Plant
Inventor: FRANKEL ADOLF
IPC: F01K3/08
Filed: 1966-09-29
Abstract: 1,173,923. Turbine power plant. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept.6, 1967 [Sept. 29, 1966], No.43614/66. Headings F1G and F1Q. A method of restarting a gas turbine 1 by means of a steam turbine 2 comprises storing, during an idle period of the gas turbine, a quantity of steam which is generated in a boiler 4 heated with gas from the exhaust of the gas turbine when working and deriving from the stored quantity at least a major part of the power required for accelerating the gas turbine by means of the steam turbine to a self sustaining speed. The steam is stored in a heat insulated vessel 3A which discharges directly through appropriate control valves to the steam turbine 2. A flash boiler 3B supplements the stored steam and supplies air ejectors 2A and sealing glands 2B. The boiler 4 includes a feedwater pre-heater 4A receiving steam remaining in vessel 3A immediately after a starting operation. In a modification. Fig.2 (not shown), the steam storage vessel 3A contains an electric heater (3c) to compensate for heat losses. In this case no flash boiler 3B is provided and the air ejectors 2A are supplied from the storage vessel 3A. The latter receives charging steam from the boiler 4 via the expansion chamber of turbine 2. The storage vessel may alternatively be formed by a high temperature water accumulator capable of releasing steam or by a steam accumulator forming part of the boiler 4. The shaft connecting the turbines 1, 2 may include a clutch so that when the plant is about to be shut down the steam turbine 2 can be stopped and an accumulation of steam built up for the restarting operation. Alternatively, the turbines 1, 2 may be on separate shafts, normally unconnected or geared together to give a common power output. In a further modification, the steam turbine 2 drives the gas turbine 1 only at starting but during normal running drives a compressor stage feeding the gas turbine. Alternatively, the steam turbine may drive a generator which supplies an electric starting motor driving the gas turbine.

Abstract: 1,010,227. Control of A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 18, 1963 [Nov. 20, 1962], No. 43862/62. Heading H2J. When switch 2 is closed to energize the stator winding 1 of a synchronous motor, current is induced in secondary phase winding A, in the form of unidirectional pulses due to rectifier 5. Pulsating direct current traverses the phase windings B, C, due to rectifier 10, the resultant currentdirection being opposite to that in the winding A. The flow periods are phasedisplaced so producing the equivalent of alternating- current flow along the axis of phase A, the directcurrent component being negligible if the ampere-turns due to the windings B, C are equal in magnitude to those due to the phase A. When the machine reaches synchronous speed, no voltage is induced in the secondary windings, but direct-current is supplied to phase A through transformer 6 and rectifier 5. In another arrangement, the rectifier bridge 5 is connected across a series circuit comprising phase A and parallel-connected phases B, C. The rectifier 10 is connected in series with a resistor across phase A only, Fig. 2 (not shown). The secondary winding may be of the threephase delta type, with one phase supplied through a full-wave rectifier and transformer, another phase shunted by a half-wave rectifier and resistor in series, and the third phase short-circuited by a conductor, Fig. 3 (not shown). In another arrangement the third phase is shunted by a resistor, or two resistors in series, the junction-point therebetween being connected to the full-wave and half-wave rectifiers.  In a selsyn system, the primary windings of several machines are connected in parallel, the secondary windings are also arranged in parallel and are connectable as described above for starting, Fig. 6 (not shown). Specification 769,746 is referred to.
