    Following is the full text of an address presented at the A.I.E.E. summer convention, Ithaca, N. Y., June 24-28, 1935, and prepared at the request of the A.I.E.E. committee on education, in order that the membership might be more fully informed concerning engineers' registration and the related problems of the profession, and may determine to what extent the arguments for registration apply to ele...

    Measurements of time lag of spark-over of small sphere gaps at 3,820 volts were made with an instrument developed specifically for the purpose. Spark lags were found to fall into 3 distinct domains: 1 of relatively long initiatory lags of random distribution, and 2 of definite formative lags of different orders of magnitude corresponding to 2 different spark-over mechanisms. The controlling condit... View full abstract»

  • Diesel Electric Motive Power for Railroads

    Publication Year: 1935, Page(s):863 - 868

    Recent developments in internal combustion engines have provided a source of mobile motive power for railroads which has shown economies over steam operation in some classes of service. The continuing development of Diesel engines gives promise of their further substitution for steam power, but in the application of this unit, performance characteristics must be considered carefully. The recently ... View full abstract»

    Consideration of the factors involved in radio interference field strength measurements indicates that the effective values measured by conventional methods are inadequate for describing the interfering effect of the disturbing radiation. The instrument described in this paper provides a means for measuring with acceptable accuracy both crest and effective values of interference field strength the... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3285 KB)

    Vacuum tube oscillators for radio frequency signals above 25 megacycles may be controlled with a high degree of precision by resonant lines, and at lower frequencies may be used to obtain a larger power output than is obtainable from crystal oscillators. The general principles of the design of concentric conductor lines and means for compensating temperature changes are discussed in this paper. Li... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3224 KB)

    By means of coupling capacitors connected to high voltage power transmission lines, high frequency carrier currents in different frequency channels may be transmitted over the power lines for supplementary services such as relaying, control, and communication. A new design of coupling capacitor has been made which, by combining 1, 2, 3, or 4 units in series, may be used on 69, 138, 230, or 287 kv ... View full abstract»

  • Corona Losses at 230 Kv With One Conductor Grounded

    Tests have been made to determine the increase in corona losses on a high voltage transmission line, due to the grounding of one of the conductors. The corona losses under this condition of operation, which may occur on a transmission system not having the neutral solidly grounded, are shown to be considerably increased over the more usual operation with all 3 conductors at the same voltage. This ... View full abstract»

    A review of available data on the magnitude and effects of lightning stroke currents, supplemented by laboratory experiments to check these effects, is presented here-with. Maximum currents of 150,000 to 200,000 amperes having durations of from 40 to 100 microseconds are indicated. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2309 KB)

    Nonuniform load growth, which sometimes results in excessive voltage drops in various parts of an electric power distribution system, caused engineers to consider extending the installation of voltage regulating devices to portions of the system beyond the station. As a result, several supplementary devices have been developed for use in distribution circuits between station and load. These device... View full abstract»

    Telephone communication to and from harbor craft in the Puget Sound area in the State of Washington is accomplished by means of low powered radiotelephone channels from each boat to a single land station from which connections can be made to any telephone; the equipment used for this purpose is described here. A 400 watt transmitter is used in the land station and a 50 watt transmitter on each boa... View full abstract»

    The radiotelephone communication system that links the 5 major islands of Hawaii and some of the engineering problems involved in developing it form the subject matter of this paper. This system, which has been in successful operation for more than 3 years, operates on frequencies between 30 and 60 megacycles per second, although in April 1935, an experimental circuit operating on 220/230 megacycl...

    By applying the results of insulation research to factory equipment and procedures, manufacturers of oil-impregnated paper-insulated cables for electric power transmission and distribution have been able to effect marked improvements in their products. By following and taking advantage of these improvements as they develop, users of cable have been able not only to obtain more satisfactory operati... View full abstract»

    During the 3 years following the discovery of heavy hydrogen in the latter part of 1931, 4 additional elementary particles of matter lighter than the alpha particle (nucleus of the ordinary helium atom) have been discovered where only 2 were known previously. This is considered extraordinary even for the present rapid pace of physics which sometimes requires physicists to revise their fundamental ... View full abstract»
