    As long ago as 1882 D'Arsonval predicted that electricity would be used widely in the treatment of disease. Today that prediction has been fulfilled — indeed, exceeded — because electricity now plays a highly important part not only in the treatment of disease but also in its detection and diagnosis. A few of the manifold electromedical applications are described here. View full abstract»

    Colored light usually is obtainable from incandescent lamps only by means of some special filtering material, at relatively low efficiency. Now a new type of lamp, which is tubular in shape and contains a powder that becomes fluorescent in the presence of ultraviolet radiation, produces white light similar in character to daylight, as well as monochromatic light, at efficiencies much larger than t...

  • Television transmission by coaxial cable

    Coaxial cables were developed originally to provide large groups of telephone channels, but their wide frequency range has led to experiments with the transmission of signals for television. High-quality signal generating and receiving equipment was used to send 240-line motion-picture images from New York to Philadelphia, as described in this article; distortion introduced by the wire-line circui...

    By cultivating a practical point of view toward today's difficult situation the young engineer may gain experience at the very outset that will assist him in solving problems likely to recur again and again throughout his entire professional career View full abstract»

    It has been known for a long time that the nonlinear relation between the flux and the magnetizing current in an iron-core transformer or choke coil results in the formation of harmonics in the magnetizing current. The magnitude of these harmonics can be obtained approximately by means of graphical methods. The following mathematical solution is, I believe, new. View full abstract»

  • Magnetic force of a solenoid

    Publication Year: 1938, Page(s):268 - 272

    The method generally employed for determining the axial and radial components of the magnetic force of a one-layer cylindrical solenoid makes use of the vector potential. While no inherent difficulties are connected with this, the calculations nevertheless are lengthy. The method here described is simpler, as it presupposes only Ampere's law. It is known that this law, which is usually given in th... View full abstract»
