  • Conductive Plastic Materials

    Publication Year: 1950, Page(s): 117
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (219 KB)

    A new class of plastic materials has been developed. The outstanding characteristic of these materials resides in the fact that they have substantial and predeterminable electrical conductivities, and yet possess the desirable general mechanical and fabrication properties of ordinary plastics. Thermosetting, thermoplastic and elastomeric variants have been produced. Representative data for one typ... View full abstract»

    The transmission requirements for radio relay systems for television network operation are discussed. A system designed by the Philco Corporation and employing heterodyne modulation with a SAC-19 Klystron, developed by the Sperry Gyroscope Corporation for this application, is described. Western Union has installed this equipment, which operates in the 6,000-Mc common carrier band, between New York... View full abstract»

  • The Design of Electronic Equipment Using Subminiature Components

    Publication Year: 1950, Page(s):130 - 135
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3992 KB)

    This article discusses briefly the advantages and disadvantages of subminiature design, and indicates the amount of space that can be saved by such design. It discusses in greater detail the major problems of design, and presents some practical suggestions concerning the methods and materials found most useful. For several years there has been an ever-increasing interest in the construction of ele... View full abstract»

  • Electron Beams in Axially Symmetrical Electric and Magnetic Fields

    The problem considered in this paper is the formulation of the equations governing the motion of an electron beam in axially symmetrical magnetic and electric fields. The equations are obtained for the trajectories of the electrons along the outer edge of the beam for the most general case, in which there are both axial and radial components of the fields. It is shown that, as a result of symmetry... View full abstract»

  • The Transmission and Reception of Elliptically Polarized Waves

    A vector parameter is defined which represents a generalization of the effective length of an antenna to include a specification of the polarization of the field radiated by the antenna. It is shown that the parameter so defined is also useful in calculating the voltage at the terminals of the antenna when it is used to receive plane waves of arbitrary (elliptical) polarization.

    The "small signal" theory of the magnetic amplifier is developed under certain simplifying assumptions. Expressions for the amplification are derived in terms of electrical and magnetic quantities, and conditions for optimum amplification are obtained. The predictions of the theory are found to agree qualitatively with experimental results of other workers. View full abstract»

  • Receiving Tubes Employing Secondary Electron Emitting Surfaces Exposed to the Evaporation from Oxide Cathodes

    Previous use of secondary-emission multiplication in receiving tubes has been accompanied by difficulties with life and has been accomplished in oxide cathode tubes by shielding the secondary emitter from cathode evaporation. This shielding required a complicated tube structure and additional electrodes and leads. This paper describes methods of controlling cathode evaporation to obtain satisfacto... View full abstract»

  • Propagation of Short Radio Waves over Desert Terrain

    Results are given of an experimental investigation of the effect of relatively simple topography and meteorology upon the propagation of short radio waves over an optical 26.7-mile path and a nonoptical 46.3-mile path. Two types of meteorological conditions were encountered during the course of the experiments performed in the Arizona desert. In the daytime the atmosphere was well mixed with the i...

  • Spurious Modes in Coaxial Transmission Line Filters

    Coaxial transmission line filters in which the shunt reactive elements are conducting rods inserted between the inner and outer conductors of the series coaxial transmission line may be analyzed by the use of well-known transmission line equations if only the TEM mode propagates. When other "spurious" modes are important, the problem is not so simple. Some equations are presented for the cutoff fr... View full abstract»

  • The Analysis of Broad-Band Microwave Ladder Networks

    Publication Year: 1950, Page(s):180 - 183
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (656 KB)

    By expressing the transmission matrix in terms of the Pauli spin matrices it has been found possible to write formulas for symmetrical ladder networks that are practical for analysis, even in the presence of gross line effect or parameter variation. These formulas are particularly useful for broad-band microwave filters. General formulas are given for the combination of 2, 3, 4, and 5 elements. De... View full abstract»
