    The equivalent series inductance and resistance of a long solenoid with nickel-steel bar has been investigated in relation to the excitation frequency for frequencies up to 14000 cycles per second. Beyond 400 cycles per second, after which only a negligible flux penetrates to the center of the bar, the inductance varies inversely with the square root of the frequency, and the resistance directly w...

  • Calculation of Characteristics and the Design of Triodes

    Publication Year: 1929, Page(s):1706 - 1749
    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3824 KB)

    The primary object of the paper is to present a simple method of designing triode vacuum tubes. It comprises three parts; the first part deals with the calculation of characteristics and constants of the triode from the electrode structures, special considerations being taken for applying the formulas already established for tubes of complicated structures. In the second part the derivation of var... View full abstract»

  • Wireless Echoes of Long Delay

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2888 KB)

    The paper discusses the various possible ways in which long delayed radio echoes may be propagated. It is proved that the echoes cannot be due to waves which are propagated in any of the following manners: (1) Along very long paths in the highly ionized part of the earth's atmosphere. (2) In any part of the earth's atmosphere so highly ionized that the group or signal velocity is very small. (3) I... View full abstract»

  • An Echo Interference Method for the Study of Radio Wave Paths

    Cited by:  Papers (4)

    An experimental determination of the rate of change of radio-frequency phase of the separate downcoming echoes has been carried out. The small power crystal-controlled oscillator circuit of the 4,435-kc transmitter operates continuously, the high-power pulse transmission being produced by modulating the power-amplifier circuits. A receiver was operated very near the transmitter, having rapid recov... View full abstract»

  • On the Relation between Long-Wave Reception and Certain Terrestrial and Solar Phenomena

    Cited by:  Papers (3)

    It is shown in the paper that there appears to be an inverse relation between long-wave reception on 75 kc per sec. and the temperatures at the transmitting and receiving stations, when the distance between them is not great. The explanation is offered that the variations i the temperatures and in the signal strength are due to a common source, the changes in the medium between the two places. If ... View full abstract»

  • The Significance of Observations of the Phase of Radio Echoes

    A method of observing the phase of radio echoes has been developed by Messrs. Tuve and Hafstad. The present note is intended to show to what extent the phase can be expected to be constant throughout the echo if the frequency-dispersion of the Kennelly-Heaviside layer is taken into account. It is shown that for reflections of 4000-kc waves with a small retardation ffective height of 200 km) the ph... View full abstract»

    The effect of large signals applied to the grid of a detector is discussed. It is shown that signals even as small as fifty mv appreciably affect the tube parameters and influence the frequency distortion. The nature of detector overloading is discussed and overload curves of the plate rectifier are presented. View full abstract»

  • Single-Wire Transmission Lines for Short-Wave Antennas

    The versatility of the possible arrangements of short-wave antennas can only be made available through the use of transmission lines. The phenomena of high-frequency transmission lines are discussed with respect to the effect of the low attenuation per wavelength and the influence of the termination on standing waves and radiation, for both an antenna and a transmission line. The single-wire trans... View full abstract»

    Theoretical consideration of the wave resonance system of tuning with distributed values of inductance and capacity are given, together with circuit arrangements embodying this method of tuning. It is shown that a high degree of selectivity is obtainable and that it offers an effective method for the elimination of interference. Multiplexing both in the transmission and reception of radio signals ... View full abstract»
