    Various types of possible danger from radio installations are considered: shocks to the operator, short-circuit from lightning or from contact with high tension power lines, breakdown from the high tension circuits of the radio transmitter itself, and harmful inductive effects from radio transmitters. In each case, instances are given together with the proper means of avoiding the undesired effect... View full abstract»

    The Sommerfeld, Austin, Fuller, and Eccles transmission formulas are compared with available data, and the conclusion reached that the Austin formula is most nearly correct. A chart is given whereby, given any five of the six quantities: wave length, transmitting and receiving antenna heights, distance of transmission, transmitting current, and received audibility, the sixth can readily be obtaine...

    In the case of a simple receiving system it is shown that even with a "perfect" rectifier, as defined, there is more high-frequency energy in the detector circuit than is associated with the rectified current. Also, with a "perfect" rectifier it is shown that the heterodyne method gives just four times the energy in the response as the "breaking up" methods give, irrespective of the amplitude of t...

  • Notes on a New Method for the Determination of the Magnetic Flux Density and Permeability

    The method described gives a ready means for determining the magnetizing force, the corresponding flux density, and permeability at any wave length whatever. In taking a series of readings for different ampere-turns and at a definite wave length, we may obtain (a) the magnetization curve, (b) the permeability-ampere-turns curve. Since the suggested arrangement applies to any practically available ... View full abstract»
