    After an historical review of the work of the United States Navy with underground and underwater receiving systems, the author gives data demonstrating the possibility of effective reception on such systems, particularly when using amplifiers. These systems are found to be directional toward waves travelling parallel to the length of the wire pair. This directional selectivity, which is marked, is... View full abstract»

    A system of simultaneous reception and transmission for radio telephony is described, together with the reasons for its use. It involves transferring the received speech (from a separate receiving antenna at some distance from the transmitting antenna) to the subscriber's line, and transferring speech originating at the subscriber's station to the radiophone transmitter. Another type of duplex rad... View full abstract»

    After considering some of the obstacles in the way of successful competition of overland radio service versus wire service, the author treats the mode of overcoming these difficulties. He recommends also radio duplex circuits; reception with loud-speaking receivers and amplifiers; trunk and way circuits from large radio centers of traffic; and relaying stations. The organization and operation of t... View full abstract»

  • A Special Type of Quenched Spark Radio Transmitter

    A quenched spark transmitter is so arranged that the capacity in the highly damped primary circuit is that between a special extra antenna and ground, and the primary and secondary circuits are partly inductively coupled thru a common inductance in the ground lead and partly capacitively coupled by the capacity between the special antenna and the usual secondary or radiating antenna. Quenching eff... View full abstract»

  • On the Multi-Section Quenched Gap

    The authors consider the relation between the breakdown voltage of a series of quenched gap sections and that of a single section. Because of electric flux leakage from each plate to nearby plates and neighboring conductors, the relation of direct proportionality does not hold. The breakdown voltage of a number of gaps of given length can not be made to exceed a limiting value, given in the paper.... View full abstract»

    The foregoing paper tells first of an investigation of the mathematical theory of electrostatically coupled circuits, and of the experimental verification of the conclusions drawn; and second, of the study, bymeans of the Braun tube and sustained oscillations, of the relations existing between the variables in the electrostatically coupled circuits using various values for the coefficient of coupl...
