Title: Improvements in or relating to radio receiving systems
IPC: H04B7/08
Filed: 1935-05-24
Abstract: 448,147. Automatic control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Crosby, M. G. : Riverhead, Long Island, New York, U.S.A.) May 24, 1935, No. 15172. Convention date. May 28, 1934. [Class 38 (iv)] [See also Group XL] A receiving system comprises means for automatically maintaining a predetermined phase relationship between carrier frequency energies derived from a plurality of aerials and means for combining the energies thus controlled. The principle may be applied to directional aerial array which is enabled to change its directivity automatically with changes in the bearing of the signal. In one embodiment, Fig. 1, two separated aerials 1, 1<1> feed superheterodyne receivers 2, 3, 5 and 2<1>, 3<1>, 5<1> with a common oscillator 4. The intermediate frequency from unit 5 is fed to the push-pull transformer 6 energizing the valves 8, 9 in phase opposition, whilst the energy from unit 5<1>, of the same frequency, is fed to the crossed coils 19, 20 through valves 17, 18 respectively. A pick-up coil 21 mounted in association with the coils 19, 20 on a rotatable shaft 22 supplies energy in parallel to the valves 8, 9 through transformer 7. When this energy is displaced in phase by 90‹ relative to that in the transformer 6, the steady currents through the solenoids 27, 28 connected in the anode circuits of valves 8, 9 are equal and the armature 25 assumes its middle position. If the relative phases change, the currents in the solenoids 27, 28 become unbalanced, the armature 25 moves to engage the flexible shaft 31, driven by a motor 26, with forward or reversing surfaces of the wheel 24 which is mounted on the shaft 22. The coil 21. is thus rotated until the correct phase relationship is restored. A pointer P may be provided on the shaft 22 co-operating with a scale S calibrated to show the direction of the incoming waves, and automatic steering may be accomplished by Selsyn motors SM1, SM2 associated with the shaft 22. In the other embodiments described, the phase adjusting means are purely electrical and include local oscillators the frequency of which is controlled by an out-of-balance voltage produced by a pair of balanced detectors when the required phase relationship is disturbed. Specification 433,843, [Group XL], is referred to.
