  • The Adjustment of the Multivibrator for Frequency Division

    Publication Year: 1931, Page(s):1909 - 1917
    Cited by:  Papers (5)

    In a multivibrator controlled by a voltage of another frequency bearing a harmonic relationship to the multivibrator frequency, the effect of varying the control voltage is analyzed, and a method for determining the best value of this voltage is described. Methods of coupling the control voltage are shown in which frequency division by an odd integer will occur more readily than by an even integer... View full abstract»

    The practical difficulties encountered in commercial operation of short-wave transmitters, due to the great number of radio-frequency stages required for crystal control, are summarized. The objections to crystal control for some transmitters operated on frequencies above 35,000 kilocycles are given. Methods are described for meeting these objections through frequency control by long radio-frequen... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4936 KB)

    This paper presents correlations between the abnormal earth currents noted during magnetic storms and transoceanic radio transmission on both long and short waves. The radio transmission data were collected on the telephone circuits operating between New York and London and between New York and Buenos Aires. The earth current data were collected on two Bell System lines extending approximately a h... View full abstract»

  • Development of a Circuit for Measuring the Negative Resistance of Pliodynatrons

    Pliodynatron oscillators are assuming greater importance in engineering work. As the value of the negative resistance of a tube having dynatron characteristics is a measure of its utility it was necessary to design a test circuit which would quickly and accurately measure this property without recourse to the older and more laborious method of plotting the Ep-Ip, curve of the...

    The problem of tubes for generating power at wavelengths below five meters is discussed. The theory of the triode and split-anode magnetron is considered with particular reference to the limitations imposed by operation at short wavelengths. Essential data are given for examples of each type of tube, showing the power that can be obtained at various wavelengths. View full abstract»

    In this paper, the writer outlines the experiments of determining the state of polarization of a downcoming wave by using a cathode-ray oscillograph of Braun-tube type. Observations have been made at the Hiraiso Radio Laboratory near Tokyo for the transmissions of JAA and JND, both of which are the high power low-frequency transmitting stations located at a short distance (about 150 and 360 km res...

    This paper describes the results of experiments which were conducted during the past two years for the purpose of studying the high-frequency transmission phenomena, and some physical explanations deduced therefrom. The authors are of opinion that it is preferable to take up the questions of polarization and direction finding simultaneously. For the measurements of polarization, the authors. used ...

    The paper begins with a brief historical résumé of the development of piezo activity for acoustic uses. References are given. Methods developed by the author and his associates permit the cheap commercial production of Rochelle salt crystals and sections thereof, but the saturation and variation with temperature of Rochelle salt (shown in diagrams) must be compensated for by special asse...
