Abstract: 980,978. Article engaging and lifting devices. FLIGHT REFUELLING Ltd. Sept. 30, 1963 [Sept. 28, 1962], No. 36929/62. Heading B8H. [Also in Division G6] To lift a closure plug 10, Fig. 1, a grab 24 is lowered into a passage 11 with inner and outer sleeves 25, 26, as shown in the left-hand side of Fig. 4, so that balls 35, 38 are retracted. When the sleeves have reached the Fig. 2 position the sleeves are relatively rotated by a handle 30, Fig. 1, and gearing 31 to the position shown in the right hand side of Fig. 4. This projects balls 35 under shoulders 21 of a ring 18 so that when the grab is raised the ring abuts a flange 23 and lifts the plug. Upward movement causes balls 38 to be projected by the flange 23 into recesses 40 in the outer sleeve thereby preventing further relative movement until the load is set down. When the plug is in use in a nuclear reactor upward pressure holds it in a position, Fig. 1, where balls 12 are retained in recesses 41. This pressure is released before removal of the plug so that it drops to a position in which the balls can move out of the recesses, Fig. 3, thus permitting the plug to be raised. In a modified embodiment, Fig. 5, both sets of balls 64, 65 are housed in an inner sleeve 58 whilst the outer sleeve has the recesses. The method of operation is similar to the first embodiment.

Abstract: 1,197,882. Multiplex radio signalling. BRITISH AIRCRAFT CORP. (OPERATING) Ltd. 25 Aug., 1967 [25 Aug., 1966], No. 38271/66. Heading H4L. In a missile control system, pitch and yaw signals which are to be transmitted in polar co-ordinate form are supplied via shapers 14, 16 to modulators 18, 20 respectively, which receive 400 C/S oscillations in quadrature from an oscillator 22. The outputs of the modulators are added at 24 to produce a signal D sin (wt. + #) which is supplied to a limiter 26 and also to a rectifier 28. A bi-stable 30 receiving a 50 C/S sawtooth wave from generator 32 converts the amplitude of the signal from rectifier 28 into width-modulated pulses at a basic repetition frequency of 50 C/S which are applied to a modulator 34. The amplitude limited signal from 26, containing only the phase information representative of the relative magnitudes of the pitch and yaw control signals is also supplied to the modulator 34 which provides a signal D'sin (wt. + 0) which is pulse width modulated at a basic frequency of 50 C/S and in which each pulse is a train of 400 C/S oscillations whose phase corresponds to that of the output of adder 24. This signal frequency modulates an R.F. carrier at 36, 38 and is transmitted. The R.F. carrier also is amplitude modulated by a phase reference signal K sin wt. from oscillator 22. Receiver.-In the missile the phase reference signal is recovered by amplitude detector 48 and supplied to a roll phase shifter 54 driven by a roll gyro 56 and providing an output K sin (wt. + #) where # is the angle of the missile. This signal is supplied via amplifier 58 as a reference phase to the motor 62 and also via amplifier and 90 degree phase shifter 60 as a reference signal to motor 64. The received signal is also supplied to a frequency detector 50 whose output D'sin (wt. + #) is limited at 66 and applied to the control phase windings of motors 62, 64. The motors 62, 64 apply torque to the airframe controls proportional to the average voltage produced by the pulse width modulation and proportional to the sine and cosine respectively of the phase difference between the control and reference voltages.
