Abstract

493,429. Wireless signalling. LORENZ AKT.-GES., C. April 8, 1938, No. 10858. Convention date, April 8, 1937. [Class 40 (v)] In a central station A, Fig. 1, for two-way radio-beam communication with a group of outlying stations B ... G, only one central transmitter Sa is used to co-operate with each of the substations as required. At the central station, directive receiving aerials E point towards each of the distant stations, and on the receipt of a calling signal from any one of them, a relay automatically turns the central transmitter Sa in the required direction As shown in Fig. 2, a calling signal from the station G, Fig. 1, energizes a relay Rg to close the circuit of a motor 5, which rotates a shaft 2 until the transmitting aerial Sa points in the require direction.. At that moment, the armature 9g drops into a notch 7 in a disc 6, mounted on the shaft 2, and so open-circuits the motor. The transmitter Sa is similarly aligned towards any station which sends out a call. An auxiliary transmitter S<1>e, Fig. 1, may be permanently set towards the transmitter Se of a particularlyimportant substation such as E.
