    Experimental work conducted for the United States Navy Department on the development of a radio meteorograph for sending down from unmanned balloons information on upper-air pressures, temperatures, and humidities, has led to radio methods applicable to the study of a large class of upper-air phenomena. The miniature transmitter sent aloft on the small balloon employs an ultra-high-frequency oscil... View full abstract»

  • Transients of Resistance-Terminated Dissipative Low-Pass and High-Pass Electric Wave Filters

    Publication Year: 1938, Page(s):1266 - 1277

    Formulas are derived for the solution of the transient receiving-end currents of resistance-terminated dissipative T- and π-type low-pass and high-pass electric wave filters. Oscillograms taken with a cathode-ray oscillograph for direct- and alternating-current cases are found to agree with the results calculated from these formulas. From these calculations the following conclusions are deriv... View full abstract»

    A new type of constant-frequency oscillator of very high stability is presented. The frequency-controlling resonant element is used as one arm of a Wheatstone resistance bridge. Kept in balance automatically by a thermally controlled arm, this bridge provides constancy of output amplitude, purity of wave form, and stabilization against fluctuations in power supply or changes in circuit elements. A... View full abstract»

  • Characteristics of the Ionosphere at Washington, D.C., August, 1938

    Publication Year: 1938, Page(s):1295 - 1298

    Data on the ordinary-wave critical frequencies and virtual heights of the ionospheric layers are presented for the period indicated in the title. The monthly average values of the maximum usable frequencies for undisturbed days, for radio transmission by way of the regular layers is also provided. View full abstract»
