    Of recent years, an active debate has been carried on relative to the justification of work in the field of "pure science" as opposed to the desirability of endeavor in the domain of "applied technology." One group of thinkers has felt that the pursuit of truth for its own sake was not only more satisfying intellectually and more stimulating to the dignity of the investigator but also, in the long...

    This paper describes a method for obtaining an engineering solution for integrodifferential equations of physical systems using an electronic system. The components consist of standard plug-in feed-back amplifier units. As the interconnections are wires, resistors, and capacitors, no complicated mechanical layout problem is involved and a generally flexible analyzer need not be set up, for it is a...

    The data on the transmission of 10- and 3-centimeter waves in low-level ocean ducts obtained by the Naval Research Laboratory expedition to Antigua, British West Indies, were analyzed by wave theory. The analysis was made for a distribution of modified index of refraction with height (shown by curve C′ in Fig. 1). Below the horizon, the 10-centimeter wave was found to propagate by the first ...

  • Microwave Oscillators Using Disk-Seal Tubes

    Publication Year: 1947, Page(s):462 - 473
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3464 KB)

    Some practical aspects of microwave oscillators using disk-seal tubes are discussed. Typical design and performance data are given. A general small-signal oscillator theory is presented and applied to the re-entrant disk-seal-tube microwave oscillator. It is shown how information on frequency of oscillation, tuning, and frequency stability can be obtained. View full abstract»

    A quantitative presentation is made of the data from a large number of tests on three types of gaseous voltage-regulator tubes, VR75, VR105, and VR150, from several manufacturers. The effect of several factors, such as time and temperature, on the voltage stability has been investigated, and an equivalent circuit of the tube was experimentally determined. These results are especially applicable wh... View full abstract»

    A derivation of the formulas available for the measurement of terminal impedances on transmission lines is given in terms of hyperbolic functions. The accuracy and usefulness of a number of different methods are considered. Results are obtained in a form suitable for convenient application to practical measuring problems involving standing-wave and resonance-curve methods. View full abstract»

    Possible methods of microwave power measurement are reviewed. The design requirements for bolometric wattmeters are outlined, and examples are given of bolometer elements that have been developed to meet these requirements. A recently developed bolometer element that may be used over an exceedingly wide band of frequencies is included. The results of experiments to investigate sources of error and...

    Design formulas and charts for the choice of inductances, Q's, and coupling coefficients of loop-antenna coupling transformers are given on the basis of signal-to-noise characteristics. A method of determining these values when a cable or other primary capacitance is present is also given. View full abstract»

    A new method of carrying on flying-boat hull design involves radio control of free-flight models. The scale factors of the models are such that severe weight and space limitations are imposed on the radio-control equipment, considering the complexity of control. Seven independent channels capable of simultaneous operation are needed. Five accomplish proportional positioning and two perform switchi... View full abstract»
