Abstract: 134,560. Robinson, J. May 27, 1918. Wireless aeronautic sign,als; directive wireless signalling; bearings and distances; determining wirelessly.-Consists mainly in determining the direction of a received wireless signal by means of two vertical coils at an angle to each other rotated about a vertical axis until no appreciable difference in strength of the received signal is observed by switching one coil in and out or reversing it to combine its effect with that of the other coil. In the form shown in Fig. 3, thetwo aerial coils 1, 2 and 3, 4 are connected in series in conjunction with an amplifier 10, such as an oscillating valve, and a telephone receiver 9. In order to keep the first aerial coil 1, 2 always in tune, an inductance 8 is put in series with the first aerial coil 1, 2 when the second aerial coil 3, 4 is switched off. In a modification, the coils are used in parallel, condensers being provided to prevent mutual disturbing effects between the two. In other modifications, the two aerial coils are connected to two primary coils acting on a single secondary coil. In another modification, Fig. 7, the two aerial coils 30, 31 are stationary and connected to two primaries 34, 35 at right-angles to each other; and two secondaries 36, 37 also at right-angles to each .other are rotated and their separate and combined effects observed in the same manner as for the two aerial coils of the form shown in Fig. 3.
