    A magnetic amplifying device is described for permitting the control of radio frequency currents by varying the saturation of the iron core of an inductance included in the radio frequency circuit. The arrangement of windings of the amplifier is such that the controlling winding has no radio frequency E. M. F. induced in it, nor does it induce currents in the radio frequency coils. Various arrange... View full abstract»

    Experiments on night transmission, on wave lengths of 500, 850 and 1,500 meters between two inland stations 1,250 kilometers apart are described. The bibliography of wave absorption is first considered critically. The average transmitting current was 12 amperes and the decrements varied from 0.09 to 0.18. The effective height of the transmitting antenna was 27 meters. Receiving was done with an au... View full abstract»

    Starting with the general solution of the differential equation of the circuit and a steady sparking state, expressions for input, output, currents, and condenser charge are calculated by means of the boundary conditions of the interval. The boundary conditions are continuity of currents at sparking and a residual condenser charge experimentally determined. Calculated current and voltage waves for... View full abstract»
