  • The flow of energy

    Publication Year: 1915, Page(s):455 - 484
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4397 KB)

    A new graphical method of representing the flow of energy is described and pictures are drawn showing the functions of generators, motors, transformers, transmission lines and other parts of an electric distributing system in terms of the flow of energy through them. The method is based on using two ribbons; one to represent the flow of energy proper, and the other (not used for direct currents) r... View full abstract»

  • Class rates for light and power systems or territories

    Publication Year: 1915, Page(s):485 - 505
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2750 KB)

    The author offers arguments in support of the principle of establishing uniform rates throughout a system or territory for different classes of service. In establishing the rates he segregates the services into eight different classes and divides the rates into energy and demand charges; the energy charges being those charges which increase with the kilowatt-hours supply and the demand charges bei...

  • The theoretical and experimental consideration of electrical precipitation

    Publication Year: 1915, Page(s):507 - 522
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5806 KB)

    Theory of electrical precipitation of suspended matter in gases is inseparably connected with the phenomena of ionization and the laws of electrically charged bodies. The motion of the suspended particle is like that of the charged pith ball in the familiar experiments, but the charge is obtained by ionization instead of contact. The paper shows that electrical precipitation occurs in nature and t... View full abstract»

    Publication Year: 1915, Page(s):523 - 565
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (17172 KB)

    The technical and finanical progress made by the Research Corporation since its organization in 1912 is given, and several plants are described. Voltages, electrode spacings, power consumption, etc., are given for several installations. Mention is made of a number of improvements in the electrical apparatus and means for its control. Progress has been made towards standardization of apparatus for ... View full abstract»

  • Continuous waves in long distance radio telegraphy

    Publication Year: 1915, Page(s):567 - 585
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6591 KB)

    Ability to predetermine the probable normal daylight-sending radius of high-powered radio telegraphic stations is of prime importance in their design. The theoretical transmission equations for both continuous and damped waves are discussed and the empirical formulas for the latter are given. Experiments with continuous waves over a period of six months between San Francisco and Honolulu, a distan... View full abstract»

  • Industrial control in the foundry

    Publication Year: 1915, Page(s):587 - 597
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2063 KB)

    Most of the control devices which are required in a foundry do not differ very materially in their functions from control devices in other industries. However, they have to encounter an unusual degree of dirt. Proper enclosing cases and the latest types of safety protection are advantageous. The crane requires a special kind of control. The difference between alternating-current control and direct... View full abstract»

  • Mill controllers

    Publication Year: 1915, Page(s):599 - 614
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1668 KB)

    Electric power is largely supplanting all other types of power for steel mill work probably on account of its superior controllability. In almost any type of mill control the object is to start, stop and reverse the machine and its load in the shortest space of time, work done at constant speed being of minor importance. This leads to an investigation of the acceleration of motor-driven machines. ... View full abstract»

  • The alternating-current coal hoist

    Publication Year: 1915, Page(s):615 - 622
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2334 KB)

    The paper describes an alternating-current coal hoist recently-installed near Pittsburgh in which dynamic braking is employed. The brakes and clutches are operated by compressed air which permits of a maximum rate of operation and also makes feasible the uses of various safety devices. The electrical equipment of the coal hoist must be capable of continuous operation at the maximum speed and any a... View full abstract»
