  • Oscillators with Automatic Control of the Threshold of Regeneration

    The frequency of an oscillator operating just on the threshold of the oscillation generation is determined-as is well known-by the constants of the circuit only; i.e., it does not depend on the operative conditions (supply voltages) of the system. The operation in this critical state for an ordinary dynatron oscillator as well as for a dynatron with back coupling can be continuously secured by mea... View full abstract»

  • Optimum Operating Conditions for Class C Amplifiers

    A theoretical analysis of the plate efficiency and output of a triode operating as a class C amplifier is made. A linear amplifier with any desired operating angle is described. Three cases in the operation of a triode as a class C amplifier are analyzed for the load impedance which will give maximum output. It is shown that for a given tube, plate voltage, and plate loss, there is a definite valu... View full abstract»

  • Magnetostrictive Alloys with Low Temperature Coefficients of Frequency

    Thirty-four magnetic alloys of iron, nickel, chromium, and cobalt were prepared and studied in order to find compositions which have substantially zero temperature coefficient of frequency of longitudinal vibration. Rods of these alloys were made to be used as secondary frequency standards, to stabilize the frequency of magnetostriction oscillators. The same alloys would be valuable for tuning for...

  • A Compact Radio Field Strength Meter

    This paper describes a compact portable field strength meter for frequencies in the broadcast band. The range of the instrument is from one volt per meter to one millivolt per meter. The theory of the resonant circuit is elaborated, and on the basis of the theory a novel method for calibrating the detector circuit is developed. A minimum of calibration is required for the instrument as a whole. Th... View full abstract»

    A previous theoretical study of a dissipationless oscillatory circuit having a periodically varying capacity predicted the existence of several interesting types of oscillations. An experimental investigation of such a circuit was therefore made. The results of this investigation are presented in this paper. The dissipation was reduced to a minimum by means of an associated vacuum tube in a regene... View full abstract»

  • Radiotelegraph Keying Transients

    Publication Year: 1934 , Page(s): 213 - 235
    Cited by:  Papers (2)

    An investigation into the nature of transients occurring when keying takes place shows that objectionable features of these transients may be reduced by suitable precautions. In the usual form of low-pass plate-supply filter, high C or low L are essential preventives of transients, and poor voltage regulation sometimes reduces their harmful effects. The transient is a damped sinusoid causing an in... View full abstract»

  • Note on a Multifrequency Automatic Recorder of Ionosphere Heights

    Publication Year: 1934 , Page(s): 236 - 246

    A system is described which gives a curve of virtual heights of the layers of the ionosphere against frequency. The pulse method of Breit and Tuve is employed with modifications. Short pulses of radio-frequency energy are transmitted, and the time required for the energy to go up and return is recorded automatically by a galvanometer oscillograph of the type previously used for fixed frequency wor...

  • Radio Observations of the Bureau of Standards during the Solar Eclipse of August 31, 1932

    Radio observations of the heights of the several layers of the ionosphere were made at Washington, D.C., and Sydney, Nova Scotia, by the pulse method during the afternoon of the solar eclipse of August 31, 1932, and during the afternoons of several days preceding and following. At Washington three separate groups of determinations were made: (1) Measurements of the maximum ionization of the E laye... View full abstract»
