  • Storage battery locomotives for mine safety

    Publication Year: 1928 , Page(s): 487 - 488
    Request Permissions | Click to expandAbstract | PDF file iconPDF (757 KB)  

    The advantage of the storage-battery locomotive with respect to safe haulage in gassy coal mines is emphasized in a paper by L. C. Ilsley issued by the United States Bureau of Mines. In coal mining, the application of the storage-battery locomotive is chiefly in gathering service in competition with animal or cable-reel locomotives. The locomotive delivers empty cars to the rooms or working places... View full abstract»

    An analysis of the surges recorded during 1927 on a 75-mi. 110-kv. double-circuit transmission line of the New England Power System is presented in this paper. The surges are classified according to cause of surge-voltage damping, extent, etc. General conclusions are drawn regarding the nature of surges and protection afforded by ground wires.

    A discussion is given of the insulation problem in relation to increased size, rating, and voltages of turbo alternators, and some results of experimental studies are given showing the possibilities of improving the insulation to take care of such increases. Mention is made of the effects of high-voltage testing and the use of hydrogen on the insulation problem, and finally, an explanation of a de... View full abstract»

    This paper outlines the experience of the New York, New Haven and Hartford Railroad with three high-speed oil circuit breakers which were installed in 1925 to serve an electrified branch line carrying freight and passenger traffic, both local and through. Satisfactory operation of paralleling commercial communication circuits, as well as of its own, presented an immediate problem, which after stud... View full abstract»

    This paper discusses procedures followed in planning future extensions to telephone exchange plants to care for increased demand for telephone service. An outline is given of the methods employed in forecasting future demand for telephone service and in determining the most efficient design of the plant to meet the service requirements. The uses made of engineering comparisons in solving the econo... View full abstract»

  • Effect of street railway mercury arc rectifiers on communication circuits

    Publication Year: 1928 , Page(s): 503 - 506
    Request Permissions | Click to expandAbstract | PDF file iconPDF (1285 KB)  

    This paper describes the effects experienced on the telephone circuits from the two mercury arc rectifier substations recently installed in Bridgeport, Conn., and shows in table form the relative magnitude of the interfering effects between rotating equipment and mercury arc rectifiers as a means of energizing the street railway system. The method and the type of apparatus used to reduce the effec... View full abstract»

  • Abridgment of interconnection of power and railroad traction: Systems by means of frequency changers

    Publication Year: 1928 , Page(s): 507 - 511
    Request Permissions | Click to expandAbstract | PDF file iconPDF (1761 KB)  

    Several types of variable ratio frequency changers are discussed and installations of such apparatus on the electrified section of the New York, New Haven & Hartford Railroad are described in some detail. These types of frequency changers permit a flexible tie between interconnected systems, and accurate and automatic control of load regardless of variations in voltage or frequency in eithe...

  • Abridgment of high-speed recorder

    Publication Year: 1928 , Page(s): 516 - 519
    Request Permissions | Click to expandAbstract | PDF file iconPDF (1640 KB)  

    This paper describes a new electrical instrument for automatically recording variations of electrical functions at high speed. The rate of chart motion is lower than that of the oscillograph so that the envelope of an a-c. wave is produced. This recorder has been successfully applied in the analysis of breakdowns on transmission lines, giving data used as the basis of securing improved selective r... View full abstract»

  • Abridgment of shunting of track circuit in a polyphase system of continuous inductive train control

    Publication Year: 1928 , Page(s): 520 - 523
    Request Permissions | Click to expandAbstract | PDF file iconPDF (1281 KB)  

    Investigations into shunting of train control track circuits have been made in the field under operating conditions by observing the operation of the primary relay on a locomotive as a train runs into a track circuit' in which there is a train ahead or an open switch and similar data have been obtained on the performance of the relay on trains in regular service. It is intended in this paper to pr... View full abstract»

    Within a relatively short time conditions in transmission systems as regards continuity of service and maximum power have radically changed. A few years ago, the amount of power transmitted over important lines was relatively small compared with their ultimate transmitting capacity. In such cases, the systems were inherently stable, and there was a reasonable margin of power with respect to load s... View full abstract»

    To the Board of Directors: In reviewing recent progress made in the application of electrical power in mines, one is inclined to conclude that it has been effected by the general economic conditions prevailing in the mining industry. Overproduction facilities in men and mines, labor problems, and freight rates are factors which are vitally influencing the prosperity and accomplishments of the busi... View full abstract»

  • Braid discharge in single conductor gable in ducts

    Publication Year: 1928 , Page(s): 534 - 536

    Where single-conductor braided, cable is used in conduit, a discharge which may destroy the cable sometimes occurs between the braid and the duct. This can be prevented by the use of a metal covering, or with certain braids. Seine twine braid with weatherproof finish has given trouble in locations where flame-proofed asbestos braid has proved satisfactory. Asbestos braid is superior to cotton brai... View full abstract»
