  • The Fixation of Atmospheric Nitrogen

    Creator:
    Fairchild, Jackson Kenelem
    Abstract:
    Much has been accomplished in the last few years toward the conservation of natural resources, and in this work the engineer has taken a leading part. The prevention of unnecessary waste, the utilization of hitherto useless by-products, and the economic production of the world's necessities are important features of this...

    Creator:
    Propst, Horace Minor and Sorenson, Edgar Adolf
    Abstract:
    During the last five years the demand for electrical energy in the state of Oregon,and throughout the entire country,has increased to such an extent that electrical generating stations have become an important factor in the economic development of the common wealth. Uonsidering the great need for cheap power, which is...

  • The Design of Hydro-Electric Power Station and Distribution System

    Creator:
    Powell, Joel William and Booth, Latimer Hobart
    Abstract:
    The marked movement of utilizing Oregon's water power in the service of generating electric current, has been promoted by the economics in transmission of electricity to distances both great and small; by the harnessing of industrial implements to electric power; and by the advancement and extension of interurban railways. It...

  • Rectifiers

    Creator:
    Harris, Lee Marion and Du Moulin, Walter Wilbur
    Abstract:
    "There are at present four common methods of con verting the alternating current into direct current. These are in order of use, the motor generator set, the rotary converter, mercury vapor rectifier and the Murphy rectifier. A short description of these and connections for the last two will be given."--p.2

  • Design of a Standard Speed, Revolving Field Type, Three Phase Alternator

    Creator:
    Williams, Floyd J. (Floyd James), 1920- and Rawson, Roy Eugene
    Abstract:
    The designing of electrical machinery is fully as essential to the thorough understanding of power equipment and apparatus, as is the taking of a laboratory testing course. One learns the relationship of the different parts, the methods of computing their dimensions, and the predetermination of outputs, efficiencies, etc. and thus...

  • High Tension Transformer

    Creator:
    Olsen, Bernhard, 1836-1922 and McLean, Howard Elmer
    Abstract:
    In view of the fact that the college authorities have purchased a set of wireless apparatus, it was thought best to design and construct a transformer of suitable size for transforming the power to be used by this set of instruments. The power required for such a set is approximately...

    Creator:
    Stutz, Lester Eugene and Pernot, Fred Eugene
    Abstract:
    Throughout the year the regular design work of the class room proved so profitable that it was thought that there was no subject which could be selected for thesis purposes of greater benefit,or which offered as great a latitude in the working out of the various problems, than the one...

  • The Testing of an Alternator

    Creator:
    Fleser, Russell Harrison and Billings, Everett Monroe
    Abstract:
    "Before a company which manufactures electrical machines allow them to leave the factory, each must undergo certain tests to make sure that there are no faults of design or workmanship and also ofttimes that they meet the specifications of the buyer. Four important tests are made, e.g. (1) no load...
