    The mathematical expressions which occur in the treatment of non-linear devices as circuit elements are interpreted in terms of a graphical physical picture of the processes involved. This picture suggests, in turn, several useful ways of applying the equations in cases where the driving forces are so large that the ordinary power series treatment becomes prohibitively cumbersome. In particular, t... View full abstract»

    This article outlines the Navy's experience and conclusions in regard to the various types of plate supply, for vacuum-tube transmitters, which have been used. After listing and briefly discussing the considerations governing the selection of an ideal plate supply for transmitters, a comparison is made between the various types and the ideal. Navy experience in regard to character and control of o... View full abstract»

  • Hot-Cathode Mercury-Vapor Rectifier Tubes

    Publication Year: 1930, Page(s):67 - 83

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2168 KB)

    High-voltage d-c power for radio transmitters has usually been obtained from d-c generators or through rectification of alternating current by means of high-vacuum tube rectifiers or mercury-arc rectifiers. A new type of rectifier tube is described which combines the advantages of the high-vacuum tube with the low and nearly constant arc-drop of the mercury-arc rectifier. Typical tube characterist...

    The question of stability in a balanced or neutralized radio-frequency amplifier is considered for one stage. Experimental and theoretical curves are given for the amplification including regeneration as the plate to control grid capacity is varied in a balanced or neutralized radio-frequency amplifier. The results are discussed for n stages of an impedance coupled amplifier by using the author's ... View full abstract»

  • Push-Pull Piezo-Electric Oscillator Circuits

    Publication Year: 1930, Page(s):95 - 100

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (680 KB)

    Comparative tests have been made of five different push-pull piezo-electric oscillator circuits. Two of these circuits use three-element tubes: (1) crystal in four-electrode mounting connected to the grids and anodes, (2) crystal in two-electrode mounting connected to the grids. The other circuits use four-element tubes, (3) screen-grid tubes with the crystal in a four-electrode mounting connected... View full abstract»

    This paper gives monthly averages of daylight signal intensity at Washington for 1928 from a number of European and American low-frequency stations. The annual field intensity averages of both European and nearby American stations were found slightly lower than those of 1927, while atmospheric disturbances varied little from the year before.

  • Multiple Signals in Short-Wave Transmission

    This paper presents an analysis of the facsimile records obtained recently in the transmissions between New York, U.S.A., and Somerton, England. Since the speed of the scanning spot in the facsimile apparatus is accurately known, these records permit the measurement of the time intervals between the various signals which produce the distortion in the received record. Thus the facsimile apparatus c... View full abstract»

  • A Condenser Bridge for Factory Inspection of Variable Condensers

    A capacity bridge designed for routine factory testing of variable air condensers of the "gang" type, as used in modern radio receivers, is described in this paper. Setting the bridge involves a capacity balance and a phase-angle adjustment. The capacity balance is effected by a balancing condenser which gives directly the capacity difference between two condensers connected to the bridge for test... View full abstract»

  • Hum in All-Electric Radio Receivers

    This paper presents the results of some further work in the field of all-electric receivers, directed particularly toward the design of receivers and power-supply systems requiring a minimum of apparatus and providing a maximum of hum eliminating action. It includes the enumeration of the causes of hum, the analysis and measurement of hum, and methods of its elimination. View full abstract»

  • Some Possibilities of Intelligence Transmission When Using a Limited Band of Frequencies

    As an ideal lower limit, certain possible methods of radiotelegraph transmission may require only a single side band of 25 cycles for each 100 words transmitted per minute, so that each average present-day short-wave channel provides enormous potential facilities for radiotelegraph transmission. Neglecting the requirements for the separation of channels to avoid interference, the maximum potential... View full abstract»
