Title: Heating circuit for vacuum tube
Inventor: TUMARKIN GERALD A
IPC: H03F1/54
Filed: 1967-12-22
Abstract: 1,138,990. Amplifiers &c. GRIFFITHS ELECTRONICS Inc. 22 Dec., 1967, No. 58411/67. Heading H3W. [Also in Division H2] In a circuit for reducing the delay normally ensuing after the switch-on of an electronic circuit employing heated-cathode vacuum tubes until the tubes are fully heated and the circuit is effective, the heaters are permanently energized from the A.C. mains 23 via transformer windings 12, 16, 18, the on/off switch 22 being by-passed in the off condition by a relay coil 34 so that the heaters receive a reduced current, the relay also holding open contacts 36 to interrupt the power supply to the high voltage electrodes of the tubes. As shown, the energized relay prevents the supply of power to the rectifier 20 supplying the other tubes in, e.g., a radio or television and the heaters of which are represented at 17. The reduced heater current passing when switch 22 is open is insufficient to cause effective electron emission. When switch 22 is closed, the heaters receive their full current and the relay de-energizes to close contacts 36 and hence supply power to the circuit.

Title: Gyroscopes producing signals indicative of the rate of change  of direction of the rotor axis
IPC: G01C19/28
Filed: 1971-12-22
Abstract: 1414297 Gyroscopes PLESSEY CO Ltd 13 Dec 1972 [22 Dec 1971] 59844/71 Heading G1C [Also in Division G31 A rate gyro comprises a rotor 4 arranged to spin adjacent to a complementary surface 10 to define a gap between the rotor 4 and such surface 10, the gap being supplied with gas under pressure in such a manner that precession of the rotor 4 due to a change in direction of its spin axis is counteracted, the pressure of the gas being indicative of the rate of turn of the gyro. As shown, a framework 1 rigidly supports a stationary shaft 2 and a spherical body 3 on which the rotor 4 is rotatably mounted by a gas bearing supplied with gas via conduits 6-9. The rotor 4 which is generally disc-shaped is arranged to rotate between two closely adjacent plate members 10 forming part of the framework 1. Each plate member 10 is provided with four pressure sensors 11 equiangularly spaced around the shaft axis and arranged in pairs such that they are able to sense precession of the rotor about two perpendicular axes which are both perpendicular to the axis of the shaft 2 and provide a fluidic pressure to correct for any deviation of the rotational axis of the rotor from coincidence with the axis of the shaft 2. Each sensor 11 may comprise a cylindrical housing (12) Fig. 2 (not shown) provided with a ring of separate holes (14) through which gas under pressure can be directed from a source (13) to an annular surface portion of the rotor 4. The back pressure, indicative of the distance between the sensor 11 and rotor 4 and therefore the rate of turn of the gyro is directed by way of a central cylindrical boss (15) to fluidic circuit and the rate of flow of gas through the apertures ensures that the pressures occurring in the gap between the sensor and rotor are such as to oppose change in size of the gap. The fluidic circuit which may comprise fluidic resistors and capacitors as well as an amplifier supplies a suitable fluidic signal to an actuator (17) Fig. 3 (not shown) for a stabilizing device associated with a vehicle on which the gyro is mounted. Since the pressure signals depend also on the rotor speed an arrangement is provided to maintain the rotor speed constant. This arrangement comprises a jet nozzle (21) Figs. 4-6, (not shown) in one of the plate members 10 which directs an air-stream over the peripheral surface of the rotor towards the other plate member. An orifice (24) is positioned in this other plate member 10 to receive the airstream only when the rotor is spinning at a predetermined rate and under these conditions a bistable fluidic device (28) is actuated to vent to atmosphere a gas-pressure source (26) which only under other conditions when the rotor is spinning too slowly, supplies gas under pressure to a nozzle (25) positioned for driving the rotor 4.
