Transmitting and receiving systems for code telegraphy; duplex telegraphs; harmonic telegraphs.-In a system for transmitting telephone or telegraph signals, in the form of trains of highfrequency oscillations, over long distances, the transmitting and receiving stations are joined by a single cable connected at both ends to an imperfect earth. The imperfect earth may be comprised by a concrete floor, a sphere in free air. or a sheet of metal, for example, tinfoil, resting directly on the floor or resting upon a non-metallic sheet on the ground. As shown in the one-way telephone system illustrated in Fig. 1, the cable L is connected at the transmitting end to an imperfect earth 4 over a battery 2 and inductance 3 which are shunted by the transmitter 1, and is connected at the receiving end to an imperfect earth 6 over the receiver 5. The transmitter and the battery may be included in a closed circuit coupled to the cable L through a transformer. For telegraphy, the transmitting end is connected to an imperfect earth over a key and a source of alternating current, while the receiving end is earthed over a receiving relay. The alternating current source, and if desired also the transmitting key, may be included in a separate circuit coupled to the cable. The correct degree of imperfection of the earths is stated to be governed by the length of cable and the working voltage. In the two-way telephone system shown in Fig. 6 (Comp.), the cable L is imperfectly earthed at each end over transmitting branches 4, 4<1> and receiving branches 6. 6<1>, the transmitters 1, 1<1> and receivers 5, 5<1> being connected in closed circuits coupled to the appropriate branches. Another modification describes a system of duplex telegraphy, with imperfectly earthed receiving and transmitting branches at each end. Alternators 2, 2<1>, Fig. 7, of different frequencies are inserted in the transmitting branches, whilst the receiving branches contain receiving devices comprising magnets 9, 9<1> and tuning forks 5, 5<1> tuned to the frequency of the alternators at the opposite ends, and impedances 8 for preventing the receivers from being influenced by local transmissions. According to modifications described in the Provisional Specification, the closed circuit containing the transmitter is directly or indirectly coupled to the cable through two transformers. The transmitting end of the cable may be connected to two imperfect earths over the transformer windings. In another modification shown in Fig. 6 (Prov.), the cable L is connected at the transmitting end to a solenoid 9, 9<1> enveloping the transformers 3, 7, 3<1>, 7<1>.
