Title: Regulating system for dividing a stream of fluid into at least two subsidiary streams
IPC: F22B35/10
Filed: 1961-02-10
Abstract: 957,055. Automatic flow and temperature control. SULZER FRERES S.A. Feb. 10, 1961 [Feb. 19, 1960], No. 5146/61. Heading G3R. In a regulating system a fluid flowing through a conduit 51 is divided into a plurality of subsidiary conduits 52, 52<SP>1</SP>, 52<SP>11</SP>. In each subsidiary conduit the flow is measured by a device 57 associated with an orifice 56. The output of the flow measuring device 57 is compared with a desired value signal derived from a tapping of a potentiometer formed by rheostats 35, 35<SP>1</SP>, 35<SP>11</SP> and the difference signal is fed to regulator 59 comprising a Ferraris motor 41 positioning a coil 38 of a differential transformer. The output of the regulator 59 controls a Ferraris motor 45, through an amplifier 40, to position a valve 55 to maintain the division flow between the valves at a desired ratio. The desired valve voltage across the rheostats 35, 35<SP>1</SP>, 35<SP>11</SP> is derived from the sum of the voltages across the secondaries of transformers 32, 32<SP>1</SP>, 32<SP>11</SP>, representative of the measured flow rates and the voltage across a secondary of a transformer 80 supplied through rectifiers 79 from transformers 72, energized by the output of the regulators 59, arranged so that the voltage across the secondary of the transformer 80 is representative of the largest regulating which occurs for that motor 45 positioning the fully open valve. In a modification, Fig. 4, not shown, the valves are controlled in dependence on the temperatures in the subsidiary conduits as sensed by resistance thermometers. In a further modification, the total flow, is derived from a flowmeter in the main conduit and not by summating the flow signals from the sensing devices in the subsidiary conduits.

Abstract: 781,010. Generating combustion products under pressure. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Feb. 22, 1955 [March 3, 1954], No. 5309/55. Class 51 (1). [Also in Group XXVI] In an exhaust reheat device for a gas turbine engine such as a turbojet engine, fuel injection means I are provided in the main combustion chamber, discharging into the combustion chamber and directed towards the turbine T so as to form within the stream of combustion gases passing to the turbine, a concentrated jet of fuel J adapted to impinge upon the turbine. The fuel is atomized on passing through the turbine and is ignited downstream of the turbine by the heat of the exhaust gases issuing from the turbine. The fuel injector I projects through an air inlet opening O in the combustion chamber flame tube Ch, and the air forms a relatively cool protective layer around the jet of fuel J so that the fuel does not come into contact with the hot gases upstream of the turbine. The fuel passes through the inlet guide vanes D and turbine T and forms a flame as indicated at F. Reheat fuel supplied from a grid Pc is ignited by the flame F and combustion is stabilized by means of the baffles E. Alternatively the whole of the reheat fuel may be supplied through one or more injectors such as I. The invention is also applicable in the case of reheat combustion equipment provided between two turbines.

Abstract: 753,371. Automatic steering control systems. NORTHROP AIRCRAFT, Inc. Feb. 26, 1954 [March 13, 1953], No. 5707/54. Class 38(4). Sideslip of an aircraft during a turn is detected by mounting a pair of accelerometers at a chosen point forwardly of the centre of gravity of the aircraft. Each accelerometer comprises a plastic case containing a conducting fluid, such as a solution of ethyl alcohol and sodium iodide, on the curved surface of which an air bubble 15, Fig. 5, moves to alter the relative resistance between contact 10 and contacts 11 and 12 respectively. The two acclerometers are mounted parallel to each other and connected as indicated at 45, Fig. 8, so that the effect of angular acceleration about a point between them is eliminated and an increased output signal dependent on sideslip angle is produced from an A.C. source 20 and applied to an electronic and mechanical amplifier-demodulator circuit 55, the D.C. output signal from which has a differential component added by a resistance-capacity circuit 49. This combined signal is added in a network 73a to a D.C. signal dependent on rudder position derived from a potentiometer 83 operated with the rudder 137, and a D.C. signal dependent on aileron position derived from a source 87, 88 by a potentiometer 75 operated with the ailerons. Delay corresponding to that between the operation of the ailerons and the commence. ment of roll is applied to the aileron position signal by a resistance-capacity circuit 42. A further small D.C. signal may be added by manual operation of a rudder trim potentiometer 50. The resultant signal is applied to an electronic and mechanical modulator-amplifier circuit 35 controlling a two-phase rudder servo. motor 107. Velocity feedback is provided by a tachometer generator 55. Compensation for airspeed variations is provided by attenuators 51, 74 and 63 adjusting the sideslip signal and the aileron position signal in accordance with airspeed.
