  • Printing telegraph systems applied to message traffic handling

    Publication Year: 1922, Page(s):79 - 91
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6591 KB)

    Ever since the building of the first practical automatic telegraph instruments by Vail in America in 1837, and Wheatstone in England in 1841, an ever-increasing amount of the world's high-speed communication has been carried on by the printing telegraph. While these early machines were built primarily for the use of the European Government Telegraphs or the large American telegraph companies, the ... View full abstract»

  • The effects of moisture on the thermal conductivity of soils: With a bibliography on the heating of cables

    Publication Year: 1922, Page(s):92 - 98

    It has been appreciated for many years that the presence of moisture in the soil surrounding underground cable was of assistance in dissipating the heat generated within the cable. But little was definitely known, however, of the exact changes in the thermal conductivity of soils caused by the presence of moisture. The following article shows that moisture plays a predominant part. The relative th... View full abstract»

  • On deviations from standard practise in lightning arresters

    Publication Year: 1922, Page(s):99 - 106

    This paper is an endeavor to answer questions of practise and criticism of arresters brought out by an investigation conducted by the Protective Devices Committee. For the most part practise in lightning arresters is standardized. In fundamental principles there have been no changes for many years. Improvements in details, especially of construction, are still being made. A new arrester, the oxide... View full abstract»

  • The “Indumor”: A kinematic device which indicates the performance of a polyphase induction machine

    Publication Year: 1922, Page(s):107 - 117
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2700 KB)

    A kinematic device is described and illustrated which represents the vector diagram of a polyphase induction machine. The parts are made to assume at will different positions corresponding to different loads of an induction motor or generator. The primary and the secondary constants, the magnetizing current, and the core loss, are also adjustable at will. The device permits the visualization of th... View full abstract»

  • Submarine cable telegraphy

    The history of the development of the subject is first outlined, and methods of operation of cables are described. The technical side is introduced with a statement of the various conditions which limit operation of cables, and a general method of analysis is developed, based upon an extension of ordinary alternating-current theory. The theory is made use of to analyze the action of cable types an... View full abstract»

  • Energy front of electric circuits

    Publication Year: 1922, Page(s):136 - 137

    AS there has been recently some discussion of the position of the energy front in an electric circuit, and as this discussion mainly consisted in quoting mathematical authorities against each other, it may be of interest to the reader who does not care to go into the mathematics of it, to discuss in non-mathematical terms the energy travel in the space surrounding a conductor carrying electric cur...

  • Five hundred tests on the dielectric strength of oil

    Publication Year: 1922, Page(s):138 - 139
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (538 KB)

    While developing a dependable method of taking experimental data with a sphere gap in transit oil, considerable study was made of the behavior of oil under disruptive dielectric stress. The following notes on the dielectric strength of oil are offered as evidence that the nature and character of the dielectric breakdown of oil may be entirely different from that of air. Five hundred successive bre... View full abstract»

    Accidental arcing grounds on transmission lines constitute the foremost problem to be solved in the transmission of electrical energy over great distances. There has come into use to a limited extent, arcing ground suppressors. This device consists in principle, of a switch in the station which is automatically closed in parallel with the accidental arc at any point out on the system. The parallel... View full abstract»

    Dr. P. W. Cobb, of the Nela Research Laboratory, has just made public a preliminary report upon some experiments which he undertook for the purpose of obtaining a fundamental idea of the influence of levels of illumination upon the speed of vision, and ultimately, if possible, of determining the exact relation existing between these two things. While these experiments make certain assumptions whic... View full abstract»

  • Electric sign lighting

    That a new era in sign lighting is on in earnest is evidenced by the rapidly increasing number of new, bigger, and brighter electric signs in all parts of the country. There is hardly a city or town of any size in which the residents have not experienced real thrills from gazing upon one or more recently-installed, attractive, interest-compelling electric signs. Whether located in the world-famous... View full abstract»

    The report of the Committee on Elimination of Waste in Industry of the American Engineering Council on “Accidents Due to Eye Defects” contains some very interesting observations regarding the prevalence of defective vision as found in the industries today. It stresses the importance of correcting subnormal vision among employees, insisting that excess eye fatigue results in condition... View full abstract»

  • Electric power application to passenger and freight elevators

    Publication Year: 1922, Page(s):152 - 164

    THE elevator controller is one of the most important and at the same time perhaps the most complicated part of the equipment as it provides many of the safety features. The smooth operation of the elevator car is largely dependent upon its functioning, and the design affects the power consumption to a marked degree. Considerable economy can be obtained by selecting the best type for each particula... View full abstract»

  • Capacity effects in inductance coils

    Publication Year: 1922, Page(s): 164
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (250 KB)

    A coil of wire wound in any of the familiar forms called “inductance coils” behaves in an electric circuit primarily as an inductance. The potentials of the different parts of the coil are, however, different from each other and from the potential of the ground. For this reason, the coil also behaves to a certain extent as an electric condenser, or rather a system of condensers. View full abstract»

    After several years of thought and discussion along similar lines, the movement for the affiliation of the architectural, engineering and other technical societies of Detroit was taken up seriously in June 1921 by the organization of a Temporary Council composed of two delegates from each of the several societies interested. The affiliation has become an accomplished fact, taking effect January 1,... View full abstract»
