    Inability to guide vessels accurately results in large losses of life and property. An arrangement by which vessels may be guided accurately will have a value corresponding to what it saves. A signal-carrying conductor along the course of a vessel, and means capable of indicating the proximity and direction of the signal conductor are described and discussed, including various forms and combinations. Ocean-going vessels entering harbors are chiefly considered, the same principle being applicable to other craft and channels, air ships, and so on. Experimental tests of the system are described in detail, with numerical data; and suggestions are made as to how the system may be further developed and applied. View full abstract»

  • Static Elimination by Directional Reception

    The author considers the possible origins of static and inclines toward a solar origin. He finds that static comes from all directions, with maximum intensity from above and maximum frequency from the horizon. The probable static wave form is a single highly damped pulse. The author then describes his early work with loop directional receivers, his invention of the so-called "Dieckmann cage," and his early work in static elimination. He gives the three-dimensional reception characteristics of linear antennas, loops, and various combinations of these. The work carried on under his direction at the Otter Cliffs, Maine, receiving station is then described in detail. Highly successful loop-and-antenna combinations were used in static elimination, and these are discussed with numerical results. View full abstract»

    After deriving formulas for received current in loop receivers or antennas (transmission being from other loops or antennas), these formulas are compared with a series of observations at various wave lengths. Good agreement is found with theory, and the residual discrepancy is partly explained. View full abstract»

    Formulas for the correct and the effective inductance, capacity, and resistance of an antenna are given. The relation of the values given to the corresponding static values is studied. The resul$s obtained are shown to agree closely with the experimentally determined values for a coil-loaded antenna. View full abstract»

    The above named paper and the original authors' preceding papers on the use of ground and water wires have been of great interest to the discussor, particularly because of the account of the elimination of interference from local transmitters at control stations. In this connection, a description of the conditions which obtained at the Naval Radio Station at San Diego, Californai, during the commentor's tour of duty there as District Communication Superintendent is outlines as it may prove of interest to other readers.

  • Electrostatically Coupled Circuits

    Publication Year: 1920 , Page(s): 434 - 440

    The expressions for the secondary frequencies secondary current, and secondary resonance current of electrostatically coupled circuits are derived theoretically. The system is shown to be practically mono-frequent even for fairly close coupling between primary and secondary circuits. The results obtained are compared with the corresponding expressions for inductive coupling. In a practical numerical example, it is found that the secondary resonance currents in the two cases are of the same order of magnitude but that the electrostatic coupling yields superior sharpness of resonance.

  • The Wave Length Relation for a Generalized Bessel's Antenna

    The differential equations for an antenna of negligible resistance and leakage conductance are set up. Proceeding from previously deduced values of the inductance and capacity per centimeter along the antenna, the solution is obtained in terms of Bessel's Functions for the voltage and current distribution along the antenna. After simplification, the solution is interpreted, and curves enabling its ready employment are given. View full abstract»
