    A system is described for electronic control of the local oscillator frequency in a superheterodyne receiver for the purpose of centering the signal carrier in the intermediate-frequency band in spite of inaccuracies of manual tuning and oscillator drift. The system consists of two parts, a discriminator for converting frequency departures into direct voltage differences, and a control circuit for... View full abstract»

    The development of two indirectly heated miniature tubes, a triode and a sharp cut-off amplifier pentode especially suited for use at high frequencies, is described. The electrical and mechanical factors involved in the design and application of these tubes are discussed and their novel structural appearance is described. Because of their decreased lead impedances, interelectrode capacitances, and... View full abstract»

  • A Note on the Source of Interstellar Interference

    Further consideration of the data obtained during observations on interstellar interference has shown that these radiations are received any time the antenna system is directed towards some part of the Milky Way system, the greatest response being obtained when the antenna points towards the center of the system. This fact leads to the conclusion that the source of these radiations is located in t... View full abstract»

  • Interfering Responses in Superheterodynes

    Superheterodyne receivers respond to other frequencies than the one for which the receiver is tuned. Various types of these undesired responses are treated in particular with one type not generally recognized, the resultant of an offresonance signal combining with the receiver's oscillator and forming a signal, at the converter tube plate, which lies in thle vicinitiy of the intermediate frequency...

  • The Present State in the Art of Blind Landing of Airplanes Using Ultra-Short Waves in Europe

    In a previous issue of the Proceedings we published a paper concerning the application of ultra-short waves in connection with navigation, based on the glide path proposed by Diamond and Dunmore. That paper not only explained the advantages of using radio beacons for this range of waves but also made mention of the fact that it is deemed expedient to use radio beacons operating on ultra-short wave...

    Continuous records of the field intensities of most of the broadcast stations in the United States have been made at the National Bureau of Standards receiving station near Washington, D.C. Typical records of received field intensities from several stations are presented. Maximum field intensities during ten-minute time intervals are analyzed in the following ways to illustrate sky-wave propagatio... View full abstract»

  • Negative Resistance and Devices for Obtaining It

    By the use of a concept due to Crisson, negative resistance is shown to be a phenomenon controlled by either current or voltage but not by both together. Thus, two main classes are found differing in the shape of the volt-ampere characteristic, in the conditions for stability, in the effect of an added positive resistance, and in the effect of an internal time lag. Reliability, good power conversi... View full abstract»

  • Comparative Analysis of Water-Cooled Tubes as Class B Audio Amplifiers

    Performance of vacuum tubes used as class B audio amplifiers has been studied with particular stress on the influence of the amplification factor, μ, on the behavior of tubes. Four types of water-cooled tubes of completely identical design differing only in μ, have been studied. The infuences of the load resistance, operating plate voltage, and no-signal current, or bias, have been graph... View full abstract»

  • An Electromechanical Representation of a Piezoelectric Crystal Used as a Transducer

    An electromechanical representation of a piezoelectric crystal which can represent the crystal when it is used to drive an external mechanical system is given in this paper. The elements of the system are evaluated in terms of the electrical, piezoelectric, and mechanical constants of the crystal. When the crystal is used as a purely electrical element, the representation reduces to the usual form... View full abstract»
