Title: Improvements in or relating to the directional transmission and reception of radio signals
IPC: G01S1/02
Filed: 1940-02-06
Abstract: 585,986. Directive wireless signalling. LAWSON, D. I., WEIGHT ON, D., and PYE, Ltd. Feb. 6, 1940, No. 2287. [Class 40 (v)] [Also in Group XXXV] Radio apparatus for detection of reflecting objects comprises two receivers with their polar diagrams slightly displaced, a transmitter emitting signals mainly along the median line, and means for shifting the polar diagrams until equality of reflected signal is attained. For detecting in three dimensions, a further pair of receivers is used. The directive effects are preferably obtained by means of electromagnetic horns. Fig. 4 shows the general arrangement of a system employing four receivers for determining direction in both the horizontal and vertical planes. The four receiving aerials, which are situated each within its own directive horn, are connected to superheterodyne receivers, the local oscillators of which are rendered operative in turn by phase-displaced switching impulses applied thereto from an impulse generator. The frequency-changers feed a common intermediate - frequency amplifier and detector and the detected signals are applied to the vertically-deflecting plates of a cathode-ray tube, so that the amplitudes of the reflected signals may be directly compared. The signal is transmitted from a similar directive horn movable with the receiving horns, and the pulses emitted are also used to synchronize the time base generator connected to the horizontally-deflecting plates. switching pulses are obtained from an A.C. supply feeding a transformer with two secondary coils 12, 12<1>, Fig. 1, across which are connected resistances 13 in series with condensers 14. The junction points are connected to earth and rectifiers poled as shown are connected across the outer ends of the secondaries. Square-topped pulses displaced in phase by 90 degrees as shown in Fig. 3 are obtained at the terminals 1 ... 4, and voltages representing the sums of pairs of these are taken off at terminals A ... D and applied to the oscillator grids of the frequency-changers of Fig. 4. The horns employed have preferably two parallel plane surfaces and two narrower diverging surfaces, and the sharpness of their directional characteristics may be varied if the diverging sides are adjustable. The horns may be of non-conducting material, the surface being metallised by spraying or other means. The system may be arranged to indicate the distance as well as the direction of the reflecting object. Marker pulses may be produced on the cathode-ray screen of the receiver as described in Specification 582,161.

These rollers are normally forced by spring-pressed plungers 21 into wedged contact with the opposed surfaces, but any two opposite ones can be pushed away therefrom by two fingers 25 which extend into the casing 16 from a sleeve fixed to the shaft 6 with lateral play and carrying the handle. Fig. 2 shows the shaft 6 held locked against motion in either direction, and Fig. 3 indicates the position taken up by the fingers 25 when the handle is turned clockwise, the rollers 20<1> being pushed into the wider part of their wedge spaces to become ineffective, the rollers 20<2> being effective for stopping only in the anti-clockwise direction. The shaft 6 may drive the drum shaft through double worm gearing, the drum being loosely carried on its shaft but connected thereto by a spring-pressed slotted disc taking over screws projecting from the drum face, the disc being readily movable away by hand to free the drum. In a modification shown the drum is replaced by a pulley to which one end of the rope is attached, the pulley being driven by pinion gearing, and a motor being connected to the finger-carrying sleeve through a centrifugal clutch which allows the motor to speed up before it is connected to the winch mechanism. A oneway adjustable brake is also mounted on the shaft 6 to make motor drive necessary even for lowering a load. The unit comprising motor, clutch and worm-drive can be readily detached and fitted to either end of the shaft 6.
