    The subject of frequency for commercial power and lighting systems, far from being settled, is discussed again with every new installation. Frequency affects the operating characteristics of circuits and apparatus, and also their cost. View full abstract»

  • Measurements of voltage and current over a long artificial power-transmission line at 25 and 60 cycles per second

    Publication Year: 1912, Page(s):805 - 837
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3442 KB)

    It is the purpose of this paper to describe in detail a series of measurements of voltage and current over an artificial power-transmission line 1040 km. (646.2 miles) in length. Although it is readily possible to compute the behavior of such a length of line, when the linear constants are given; yet this is the first time, so far as the writers are aware, that actual observations have been forthc...

  • The electric strength of air — III

    The two earlier papers of this series discussed more particularly the conditions governing the start of the high voltage corona. This line of investigation is continued to some extent in the present paper. In addition some interesting observations of the properties of the full-formed corona itself are recorded.

  • Metallic tungsten and some of its applications

    Publication Year: 1912, Page(s):865 - 874
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (974 KB)

    Tungsten does not occur as such in nature; but in the form of compounds it is pretty well distributed. The most important ores are sheelite or calcium tungstate and wolframite or iron-manganese tungstate. The principal source of the ore at this time in this country is Boulder County, Colorado.

  • Thirty years' progress in the electric furnace

    Publication Year: 1912, Page(s):875 - 883
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1012 KB)

    There has been so much written about the electric furnace since it entered into regular commercial use about 20 years ago that the presentation of a paper on the subject treating it in a general way is not apt to be interesting. But a promise to attempt the preparation of such a paper having been given, it was thought that there might be some interest attaching to a review of the development of so... View full abstract»

    Modern tendencies are toward greater efficiency, in machinery as also in a more scientific management and in many other directions involving the saving of useless labor or wasted efforts, as exemplified for instance in simplified spelling the use of abbreviations, the Esperanto language, etc. Obsolete, old-fashioned and inefficient machinery is willingly discarded for that which is more efficient;...

  • The transient reactions of alternators

    This paper is confined to demonstrating the existence of a characteristic of alternators provisionally named the transient impedance and to investigating the influence of this characteristic on a. The maximum and minimum currents flowing through a 12,000-kw turbo-alternator with and without external reactance coils, under various short circuit conditions. b. The maximum and minimum currents into d... View full abstract»

    The purpose of this article is to publish a few observations made in the research laboratory on some phenomena in vacua, as they may possibly be of interest to others who are working in the field of evacuated apparatus. View full abstract»

  • Military telegraph lines using the polarized sounder as receiving instrument

    Publication Year: 1912, Page(s):931 - 950

    It is well known that, in time of war, the army has considerable difficulty in keeping up its overland telegraph lines, and especially so if these lines are operated on the ordinary Morse system and with wet cells. In actual warfare, in the field, all impedimenta must be reduced to a minimum, and consist of as little perishable material as possible. If, for example, it is desired to operate a clos...

  • Motor starting currents as affecting large transmission systems

    From time to time those responsible for the operation of electrical systems have displayed a disposition to place a definite limit upon the size of motors which they will allow upon their circuits. This tendency seems to be more pronounced in alternating-current than in direct-current systems, but is observable in both. Moreover, in alternating-current systems the tendency is not confined to centr... View full abstract»
