Title: Improvements in or relating to frequency control systems
IPC: H03L7/10
Filed: 1958-03-19
Abstract: 873,078. Automatic frequency and phase control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 19, 1958 [March 22 1957], No. 8825/58. Class 40(5) A gate circuit permits signals to be passed to a phase detector retroactively controlling the frequency and phase of the signals (in conjunction with reference waves of the same frequency.) only when the signal and reference waves are within phase and amplitude relations detected by another phase detector which controls the gate circuit. As shown an intermediate frequency (I.F.) is applied through a gated amplifier V 1 , to a phase discriminator 21 with its other and reference input applied from a terminal 24 to derive, at 22, an automatic frequency or phase control voltage. The I.F. after phase shift of 90 degrees in circuit 2 is also applied with the reference oscillation to a phase sensitive rectifier circuit 9, 10, 11 whose output, in series with a negative bias voltage applied at 25 and a positive bias voltage derived by rectifying part of the I.F. input in circuit 20, 14, 15, is applied to open the gate valve V 1  when the inputs to the phase sensitive rectifier 10, 11 are in a predetermined phase or anti-phase relation for some time, i.e. the input I.F. and reference wave approximately in the phase quadrature relation around which the D.C. output at 22 is variable in magnitude and polarity for AFC control. Due to rectifier circuit 14, 20, 15 the A.F.C. control ceases if the I.F. is of insufficient amplitude. The switch 23 may reverse the phase of the reference oscillation, including its input to discriminator 21, so that the image of the controlled frequency producing the same I.F. frequency with a stable heterodyning source may instead be controlled. In a modification (Fig. 2) the valve V 1  feeds either end of the tuned circuit 8 through a phase reversing switch 24, and its output applied through a 90 degrees phase shift RC network 9, 10 to one end of a rectifier circuit 12, 11 to the other end of which an amplified reference wave is applied to produce, when the input I.F. and reference wave are in a predetermined 90 degrees phase lead or by relation, a positive bias on a normally blocked valve V 3  whose output opens a normally blocked rectifier gate circuit 5, 6 between the valve V 1  acting also as a cathode follower and the phase discriminator 21, to which the reference wave is also applied from the cathode follower valve V 2 . The gate circuit 5, 6 normally self blocking by rectifying the input from valve V 1 .

Abstract: 647,472. Elevating and training gear for guns. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. April 5, 1947, No. 9240. [Class 92 (i) ] [Also in Group XXIX] In a hydraulic control system in which a controlled element is moved at a velocity which is always proportional to the displacement of a control member and in which the controlled element has imparted thereto a superimposed displacement proportional to the displacement of the control member the energy for imparting the superimposed displacement to the controlled element is obtained from a hydraulic accumulator. A gun turret (not shown) is rotated by means of a pinion 6 which meshes with a toothed ring surrounding the turret. The pinion 6 is driven through a gear 5 by a hydraulic motor 4 supplied with liquid under pressure by means of a hydraulic pump 1. By means of a rack 7 the casing of the motor 4 can be rotated through a gear 8 and teeth 9 carried by the casing. The rotation of the casing imparts a rotational movement to the turret. A hand control lever 2 controls by a link 3a the stroke of the pump 1 and this controls the speed of the motor 4. At the same time, displacement of the lever 2 operates through a servo motor including a differential linkage 14, 16 to operate the rack 7. A valve 13 admits liquid to a jack 10 connected to the rack 7 which is thus displaced an amount in proportion to the displacement of the lever 2. A hydraulic accumulator 11 supplied with liquid under pressure either from a pump 12 or from additional cylinders in the pump 1 supplies liquid under pressure to operate the jack. In a modification, the hydraulic motor 4 may be a hydraulic jack for moving guns in elevation relative to the turret, the casing of the jack being displaced to impart displacement to the guns. In place of the plunger and rack, a hydraulic motor and gearing may be employed. The description refers to a system in which instead of a hydraulic pump having its stroke variable, a throttle valve is employed with a fixed displacement pump and a short circuit is connected across the pump and contains a relief valve, the volume of liquid passing to the motor being controlled by the throttle device. Specification 647,473 is referred to.
