    This paper describes the construction, theory, and performance of various types of fixed field secondary emission multipliers. Detailed consideration is given of multiplier phototubes employing crossed electrostatic and magnetic fields and of electron multipliers using electrostatic focusing alone, to serve as coupling and amplifying units for cathode-ray tubes such as the "Iconoscope." It is show... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (720 KB)

    International communication has been bettered by the opening of eight radiotelegraph and of nine radiotelephone direct circuits. The first around-the-world two-way telephone conversation took place this year in New York over wire to San Francisco, by radio to Java, by radio to Amsterdam, by wire to London and by radio to New York, a total distance of 23,000 miles. Many nations improved their natio... View full abstract»

    Developments in radio communication in the mobile services during 1935 have been largely in the nature of gradual improvement of existing equipments and services. In the marine field, the safety-of-life aspect is assuming increased importance. Rearrangements have been made of the frequencies and the schedules of radio beacons to avoid interference thereby making the system more effective. The impr... View full abstract»

    The circuits which have proved especially suitable for receiving television broadcasts from Berlin are described. The arrangements in the high-frequency portion, conditions during rectification, the production of synchronizing impulses of constant amplitude, and a relaxation oscillator circuit producing symmetrical voltages of large amplitude, are discussed. Photographs of television pictures prov... View full abstract»

  • Losses in Twisted Pair Transmission Lines at Radio Frequencies

    Publication Year: 1936, Page(s):425 - 432
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (968 KB)

    It is generally believed that the losses in twisted pair transmission lines at radio frequencies are high, but the magnitude of the losses at frequencies between one and fifteen megacycles is perhaps not so well appreciated. This discussion deals with the use of several kinds of twisted pair conductors available in the market, when used as transmission lines between an antenna system and a radio r... View full abstract»

  • Present Practice in the Synchronous Operation of Broadcast Stations as Exemplified by WBBM and KFAB

    Publication Year: 1936, Page(s):433 - 446

    This paper briefly covers the history of synchronization of broadcast stations in the United States and abroad. The WBZ-WBZA system, as developed by Westinghouse, is described as typical of the "derived-carrier" type of synchronization. A new system of synchronization and equipment, developed by Bell Telephone Laboratories and the Western Electric Company and used successfully by WBBM and KFAB for... View full abstract»

  • Grid Temperature as a Limiting Factor in Vacuum Tube Operation

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (960 KB)

    A method for determining the grid dissipation at which primary or thermionic emission from the grid begins has been devised. By means of suitable rectifiers and an alternating-current source, the grid is heated during positive half cycles and the presence of primary emission is determined during negative half cycles. A variation of this method also enables one to measure the grid dissipation limit... View full abstract»

  • Terrestrial Magnetism and Its Relation to World-Wide Short-Wave Communications

    The functioning of short-wave circuits is found to be closely related to the geographical distribution of terrestrial magnetic activity. Circuit fading and magnetic fluctuations may be correlated in terms of horizontal intensity communication limits. North American magnetogram studies have provided a direct relationship between short-wave communication effectiveness and north latitude. The world m... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1992 KB)

    Continuous records of field intensity taken at several receiving points and on various types of antenna systems are compared. Evidence of incoherent low-frequency fading is found. Several measures of variability are discussed and changes observed are compared with variations in earth potentials. Abnormally low group velocities for low-frequency transmission are discussed.

    The more important defects of class B audio-frequency amplifiers are classified and examined in detail. A general method of determining harmonic components introduced by curvature and asymmetry of the combined plate current curves of a pair of tubes is given, with a tabulation of results in a practical case. The main body of the paper deals with an accurate quantitative determination of the harmon... View full abstract»

    The chief characteristics of quartz plates cut at various angles to the crystal axes are described, with particular attention to the effect of temperature on frequency of oscillation. Methods of reducing these temperature effects lead to the manufacture of zero temperature coefficient plates. Their application to existing transmitters previously employing X-cut plates is described. Particularly st... View full abstract»
