    The research was suggested by the following two facts: (1) The dynatron oscillator, as compared with the feed-back oscillators, has a much better "frequency stability" (i.e., its frequency is much more independent of changes in the applied electrode voltages); (2) The Pierce types of crystal or magnetostriction oscillators are really controlled feed-back oscillators. One type of magnetostriction c... View full abstract»

    The use of tuning forks as audio-frequency standards is treated. Two frequency standards employing alloy forks and one employing a steel fork were checked against each other by apparatus allowing a continuous and simultaneous checking of all three forks. Suitable circuits and requirements for high precision and constancy of output are outlined. One of the frequency standards and a method of obtain... View full abstract»

    The reception of a self-synchronized cathode ray television image in an airplane demonstrated this type of television under conditions of far greater rigor than are to be met in practice. Employing the ultra-high frequency of 44,500 kilocycles, or 6 3/4 meters, images were received from the Don Lee television station W6XAO while traveling at the speed of 120 miles per hour above the city of Los An...

    An electronic oscillator of the magnetostatic type, for generating wavelengths of less than 50 centimeters, is described. The operating characteristics of this oscillator are given, with particular reference to obtaining maximum output and efficiency. A thorough experimental investigation of the effect of inclining the magnetic field is presented, and its importance in obtaining maximum output is ... View full abstract»

  • Radio Guidance

    Publication Year: 1932, Page(s):1752 - 1762

    The writer proposes a system for radio guidance by means of the rotating radio beacon. The system described would employ two rotating radio beacons transmitting simultaneously and on the same frequency. A radio receiver carried aboard the craft to be guided would receive the combined transmission from the two beacons. Special equipment for this receiver's output would take bearings from the two be... View full abstract»

    The conventional formula for power output is accurate when even harmonics only are present but it does not give the true power output if odd harmonics are present. It is shown that the correction factor to be applied is the square of one plus or minus the ratio of the third harmonic amplitude to that of the fundamental. Output systems are discussed in which the even harmonics are inherently low, s... View full abstract»

  • The Radio Receiver Characteristics Related to the Side-Band Coefficient of the Resonance Circuit

    Publication Year: 1932, Page(s):1774 - 1801

    In the investigation of the over-all sensitivity, fidelity, and selectivity of radio receivers, it is necessary to consider not only the performance of the detector and amplifier, but also the modulated current in the resonant circuits. The general statement that the side bands of the modulated current are cut off in resonant circuits is not sufficient for a complete description of the over-all pe... View full abstract»

  • The Effect of Displacement Currents on the High-Frequency Resistance of Circular Single-Layer Coils

    In existing theoretical formulas for obtaining the high-frequency resistance of circular single-layer coils, the effect of displacement currents has been neglected. It was thought that the displacement currents in going from one turn of the coil to another through the dielectric, would affect the distribution of current over the cross section of the conductor and, consequently, the effective resis...

    Working formulas for the calculation of input impedances and attenuation are obtained for a transmission line in which the inductance and resistance per unit length are linear functions of distance, and in which the capacitance and leakance are constant. Generalized functions used in the formulas, which were developed in an earlier paper, are here expressed in terms of Bessel's functions of the in... View full abstract»
