Multiplex combinations for economic telegraphy and telephony (1913)
Jones, Rupert Forrest · leaf 22
M and ft. Aninduced leakage telephone current cannot flow through the tele-graph instruments since there is no connection from the groundto the lines, if the latter are in the clear on the poles. The impedance coils however, form a high resistanceshort circuit to the telephone, and ringing… … Transformers with windings of an equal number of turnsare represented in circuit at HMM and N respectively. Theresistance of the primary (instrument side) of each transformeris nearly equal to that of the secondary (line side), and theinductances are equal. The transformers nMH and Nn are #8 called…
