Abstract: 871,148. Frequency discriminators; valve limiting circuits. BRITISH BROADCASTING CORPORATION. May 14, 1958 [May 14, 1957; Sept. 17, 1957], Nos. 15323/57 and 29298/57. Classes 40(5) and 40(6) In a frequency discriminator an input circuit is coupled to a tuned circuit 19, 28 inductively coupled to a tuned circuit 20, 29, one tuned circuit being connected to the centre tap of the other to form vector sum and difference pairs of outputs which are rectified and differentially combined in series connected load circuits 23, 25 and 24, 26 to produce a detected output at 27. A diode limiter 18 is also connected across the input circuit 17, 13 without producing distortion at the discriminator output and may be back biased by the voltage produced by the anode current of the amplifier tube 12. The inductors 19, 20 may be of low and high impedance respectively. Alternatively, the coupling between the input circuit and first tuned circuit may be capacitive. Also limiting may be produced by automatic gain control from a rectifier connected to the input circuit, or the diode limiter circuit 18 may be connected between anode and control grid of the valve 12 or across a further inductor coupled to the input circuit inductor 13. The limiter bias may also depend on signal voltage. Further, the limiter may be connected between the anodes of the two valves preceding the discriminator, and may be back biased by an R-C circuit in the anode circuit of the first of the two valves.

Abstract: 544,786. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Oct. 26, 1940, No. 15737. Convention date, Oct. 26, 1939. [Class 97 (iii)] A gyroscope apparatus for showing on one indicator the pitch, roll and heading in azimuth of aircraft comprises two neutral gyroscopes, the first of which has an horizontal spin axis and is mounted in a supporting frame with freedom to precess about a vertical axis and about an horizontal axis perpendicular to its spin axis, whilst the second gyroscope which serves to stabilize the supporting frame of the first gyroscope and is provided with gravity-responsive erecting means, has a vertical spin axis free to precess about two mutually perpendicular horizontal axes. The device is provided with an annular indicator in the form of a side reading compass card 3, Fig. 4, connected to the instrument so as to rotate in azimuth relative to the housing and to move up and down and to tilt laterally. The index 4 moves with the compass card except for azimuthal movements. The device may be of the vacuum driven type wherein air is con. tinuously exhausted through a pipe 501, Fig. 1, and enters through a screen 51 whence passes through a channel 15 to the spinning nozzles of the two rotors 10, 31. The rotor 10 which is of inverted bowl shape, spins about a vertical pivot 22 carried in a casing 9 mounted in a gimbal ring 12 permitting movement about two horizontal axes at right angles. The rotor 10 thus stabilizes the frame 9 against both pitch and roll. The frame is erected by the usual pendulous shutters 40 co-operating with air escaping from a chamber 38. A hollow sphere or housing 23 pivotally supporting a vertical ring 7 and a directional gyroscope 8 is secured in the frame 9. An extension 6 of the vertical ring 7 carries a frame 5 to which the annular compass card 3 is attached. To prevent wandering of the directional gyroscope 8 a compass magnet 41 pivoted on the frame 5 carries a baffle ring 44 which differentially intercepts air jets from vertical ports 46, 47 to cause the gyroscope 8 to follow the magnet in azimuth. Tilt of the rotor axes of the gyroscope 8 is corrected by pendulum shutters 50 according to the method disclosed in Specifications 505,900 and 505,901.
