    IN the summer of 1917, the Chicago, Milwaukee & St. Paul Railway Company issued specifications covering the apparatus necessary for the electrification of their line from Othello to Seattle and Tacoma. The following were the principal requirements for passenger locomotives as finally determined by the Railway Company: View full abstract»

    DECEMBER 9th, 1915, may be considered the date of the initial electrical operation over the electrified lines of the Chicago, Milwaukee & St. Paul Railroad. During the following winter the electrification was extended over 440 miles of route from Harlowton, Montana, to Avery, Idaho, a section which crossed the Belt Mts., the Rocky Mts., and the Bitter Roots. The locomotives for this initial... View full abstract»

    WITH the increasing application of 60-cycle synchronous converters to railway service, the question of flashing is receiving considerable attention. A series of tests has recently been made, and others are still in progress, with a view to determining the possibilities of protection from flashing by various methods, including the “quick-acting breaker,” “flash suppressor, ...

  • Automatic substations for heavy city service

    WHEN automatically controlled substation equipment was in the development stage, the general consensus of opinion was that its greatest field lay in relieving the smaller interurban systems of a greater portion of their substation operating labor. While many such systems have installed one or more automatic substations, they have not displayed the interest in the matter that was expected. In many ... View full abstract»

    The article covers the theory and operation of Audion oscillator circuits. It embraces phase relations in various circuits, frequency of operation, simplification of complex circuits, and the behavior of oscillators as a function of its many variables. Vector diagrams are given of the phase relations in several simple circuits. The similarity of more complicated circuits to the simple ones is illu... View full abstract»

  • Economic voltage of long transmission lines

    Publication Year: 1920, Page(s):377 - 381

    THERE has been a need of a rational method of determining the economic voltage for a proposed transmission line. This voltage has often been decided upon after making several lengthy cost estimates of lines at different operating voltages. It is the purpose of this paper to indicate a solution by an application of Kelvin's Law. While this law has certain limitations, of which the engineer must be ... View full abstract»

    It has been mentioned that when using a detecting instrument of quite high sensitivity it is necessary to go to very large sizes of the magnet and detecting coil, in order to reach even moderate distances of detection, if no other means are used for increasing the sensitivity.

  • Magnetic and electrical properties of iron-nickel alloys

    Publication Year: 1920, Page(s):396 - 405

    Part 1. This investigation was undertaken to determine whether any iron-nickel alloys could be found having a higher saturation value than pure iron. Alloys were prepared containing 0–100 per cent Ni. Pure Fe-Ni alloys do not forge readily, and to make them forgeable it is necessary to add alloying elements like Mn or Ti. The results show that the saturation value decreases slowly with incr... View full abstract»

    THE very great increase in the demand for nitrates during the war for the manufacture of explosives and fertilizers, together with the shortage of imported Chile saltpeter, which was the principal source of nitrates before the war, has been emphasized sufficiently in previous papers. This condition of increased demand and curtailed supply led not only to the establishment of many manufacturing pla... View full abstract»
