  • Plant efficiency: An analysis of the losses of a hydroelectric system

    Publication Year: 1912, Page(s):467 - 480
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1264 KB)

    The following paper is an analysis of the losses and efficiencies of the Seattle Municipal Light and Power plant for the year 1911. Great care has been taken in these measurements and the results have been checked in as many ways as possible and instruments have been frequently calibrated. These figures are therefore believed to be a close approximation to the true values. View full abstract»

    One of the most important portions of the outside plant of the companies engaged in the transmission of energy or intelligence is the structure for supporting the conductors, and as such it is receiving a constantly increasing consideration from engineers, as the value of an uninterrupted service at the least cost is being realized.

    Purposes Early in the 15th century street lights were ordered in Paris, France, to prevent crimes of violence. This was at a time when the only occupants of the streets after night were belated pedestrians and a few vehicles. In the present day the use of our streets by night is growing and ever increasing. In fact the traffic in certain sections is heavier, in some cities, during the earlier part... View full abstract»

  • Does it pay the average coal mine to purchase central station power?

    In the application of central station power to coal mines the successful operator of today is sometimes at a loss to know just what saving will be effected, for the following reasons: first, he believes that he is producing power at a fairly low cost, due to cheap fuel, simple apparatus and low cost of buildings; second, hot knowing approximately his costs in detail, he is at first unable to see h...

  • Motor and control equipment of electrically operated valves

    Publication Year: 1912, Page(s):535 - 538
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (442 KB)

    Valves of 24 in. (60 cm.) diameter and larger are usually operated other than by hand for the reason that generally such valves must be closed in a very short time, which is impossible by hand-operation, and also because such valves are frequently located in out of the way places and more conveniently controlled from some operating point more or less remote from the valves.

  • Advantages of automatic control in steel plant operation

    Publication Year: 1912, Page(s):539 - 544
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (694 KB)

    The problem of motor control in industrial practise and especially in steel plant operation is one in which there is as great a diversity of opinion as in any other problem that presents itself to the industrial engineer. In this paper, it is the intention to take up some of the reasons for the use of automatic control for motors as opposed to manual control, and also some of the tests which have ...

  • Direct-current and alternating-current mill motors for auxiliary drives

    Publication Year: 1912, Page(s):545 - 558
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2923 KB)

    Direct-Current Mill Type Motor Motor drive for the auxiliary apparatus of steel mills, including tables, screw-downs, cranes, charging machines, etc., has been used for about twenty years. The application of motors to the various machines was naturally a very gradual process. The conditions were very unusual, as the work was of an extremely severe nature, requiring frequent starting and stopping, ... View full abstract»
