Abstract: 457,989. Gear for retracting or operating aircraft elements ; bomb-dropping apparatus. FAIREY AVIATION CO., Ltd., North Hyde Road, Hayes, Middlesex, LOBELLE, M. J. 0., 298, Langley Road, Langley, Buckinghamshire, and VOSS, E., Bourne House, Dawley Road, Hayes, Middlesex. Sept. 12, 1935, No. 25347. [Class 4] [See also Group XXI] Mechanism for the retraction of an aircraft under-carriage or of bomb or torpedo gear, or for operating slots, flaps or rudder servo bias control comprises a pivoted lever of which one end carries or constitutes the member to be retracted or operated and the other end is formed with a slot in which the free end of a rotatable arm slides, the arrangement being such that the lever and the arm are at right angles to each other in the limiting operated positions. The pivoted lever 12 carrying the wheel 11 or other member to be retracted has the slot 17 engaged by a pin 18 on a lever-arm 19 formed with an arm 20 connected by a rod 21 to a hydraulic cylinder 22. Rotation of the lever 12 is effected by a hydraulic cylinder 27 through a link 26 which engages a lug 26 on the lever. Retraction or extension is effected by liquid fed to the cylinders 22, 27 through pipes 23, 28 or 24, 29. A snap spring 30 secured to a lug 31 on the arm 19, 20 assists the locking action in the extreme positions. In a modification, Fig. 3, applied to flapcontrolling mechanism, the flap 32 forms one arm of a lever, the other end of which has a slot 34 engaged by a pin 35 on an arm 36 carried on a shaft 37 rotated from the cockpit, the arm 36 and the flap-carrying lever being at right.angles in the extreme positions.

Abstract: 1,152,265. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 10 June, 1966 [26 June, 1965], No. 25855/66. Heading H4F. In a circuit for separating the quadrature phase components of a P.A.L. colour carrier wave comprising a one-line-interval delay line 5 and circuits 23, 24 and 21, 22, respectively, for adding and subtracting the delayed and undelayed carrier signals, the carrier wave is applied to the circuit by means of a transformer 9 having push-pull windings 6 and 10, with winding 6 connected to the input terminals of the delay line and arranged so that the inductance of the winding substantially neutralizes the reactance of the input capacitance 11 of the line at the frequency of the colour carrier wave. Winding 10 provides the carrier signal of opposite phase for the subtracting circuit 21, 22. Windings 6 and 10 are wound in bifilar manner (Fig. 2, not shown) to ensure close coupling, and an additional adjustable single-turn winding 27 is provided for equalizing the two transformer outputs. The transformer has an adjustable core to permit variation of the inductance. The output from the delay line is connected to a second delay line 19 through an auto-transformer 15 and a potentiometer network 16, 17. The characteristic impedance of line 19 has a value corresponding to the input resistance of circuits 21, 22 and 23, 24. The additional winding 27 may be dispensed with by: (1) substituting an adjustable potentiometer for resistors 21 and 22, (2) connecting a potentiometer in series with resistors 21 and 22, (3) constructing resistor 21 to be adjustable (as illustrated), or (4) connecting circuits 21, 22 and 23, 24 together by a potentiometer the slider of which is connected to delay line 19. An alternative circuit is described with reference to Fig. 3 (not shown) in which transformer 9 has a primary winding suitable for matching to a high impedance source, such as the anode circuit of a valve or the collector circuit of a transistor.
