Patent GB-1296422-A (GB)
IPC: F02C9/32
Filed: 1970-06-24
Abstract: 1296422 Gas turbine engine fuel systems G BAYARD 24 June 1970 [1 July 1969] 30657/70 Heading F1G A gas turbine engine comprises spill burners 27 supplied with fuel via a constant-flow regulator 35 comprising a by-pass valve 38 which returns fuel to tank 33 via a by-pass line 43 if the pressure drop through an orifice 42 exceeds a valve determined by the force of a spring 41 whereby the pressure drop and therefore the flow to the burners is maintained constant. Fuel is spilled from the burners 27 via a spill line 29 and a spill flow control 32 which comprises a throttle valve 12 controlled by an evacuated capsule 16, the pressure drop across the throttle valve 12 being kept constant by means of a further throttle valve 3 connected in series with it and subjected to the pressure drop. The capsule 16 is exposed externally to the pressure downstream of a restrictor 47 in a line 46 subjected to the discharge pressure of the compressor 24. During starting, when the engine is running up to operation speed, the capsule 16 is subjected to the full discharge pressure of the compressor, and the net fuel-flow through the burners 27 is consequently controlled so as to exceed the value for steady-state operation. When the desired speed of the compressor 24 and its driving turbine is reached, a governor 30 opens a leak-off valve 37 downstream of the restrictor 47, and when the desired speed of the free turbine 25 is reached, a governor 31 opens a similar leak-off valve in parallel with the valve 37, whereby the pressure acting on the capsule 16 is dropped to a value at which the net fuel-flow is equal to that for steady-state operation at those speeds. Any subsequent variation of either of these speeds causes a variation of the opening of the corresponding leak-off valve tending to correct the speed variation.

Abstract: 1304496 Measuring angular velocity electrically MOSKOVSKY ZAVOD ELEKTROVAKUUMNYKH PRIBOROV 11 Nov 1971 52382/71 Heading G1N [Also in Divisions H1 and H3] A transducer for measuring angular velocity comprises a tuning fork with its axis on the axis of rotation, made to vibrate at its resonant frequency, so that it acts as an inertia body, and an electro-mechanical pick-up for sensing torsional vibrations of the fork when the assembly is rotated about its axis. The tuning fork 1 Fig. 1, comprises a central stem 8 fixed to the cap 23 of an evacuated glass cylindrical housing 24, having symmetrical magnetic prongs between which is located an exciting coil 3 on a core 4, and an indirectly heated cathode 2.

The stem 8 carries a plate 5, Fig.2 at its upper end, which is oscillated by the stem when the complete assembly is subjected to an angular rotation. Plate 5 and member 9 form a diode with varying conductance, and is energized by battery 34, Fig.4, the A. C. output voltage 11, across load resistor 33 being proportional to the angular velocity. In modifications (a) the plate 5 and cathode 9 are duplicated for mechanical balancing, (b) a fixed grid is located between each anode and cathode, (c) a displaceable grid is used with each electronic unit, attached to the prongs and the stem of the tuning fork, and fixed anode plates are added.
