    The development in the application of electric drive to the lumber industry has been exceptionally rapid. Successful sawmill companies are now even operating entirely from central station service, notwithstanding the large amounts of refuse available for fuel. The paper considers the lumbering industry as carried on in Washington and Oregon, and describes the application of electric power to the v... View full abstract»

  • Insulator depreciation and effect on operation

    Investigation shows that insulator trouble increasing with time is not due to fatigue in the material under applied working loads, but rather to depreciation caused by the absorption of water by porous material or by the cracking of the dielectric from high internal mechanical stress set up by uneven temperature in the dielectric, or by greater expansion of cement or metal, or stress from a combin...

  • Effect of altitude on the spark-over voltages of bushings, leads and insulators

    The dielectric strength of air decreases with decreasing pressure and increasing temperature; that is, with the density. Therefore, at high altitudes where the barometric pressure is low, brush discharge starts and spark-over takes place at lower voltages than at sea level. The effect of air density on corona, and spark-over between spheres, etc., has already been given. In the following investiga... View full abstract»

    D. B. Rushmore: There is a fairly sharp dividing line which distinguishes motor application work from other fields of engineering, except railway work, which must be considered as a specific field in itself. The field of motor application is very largely that of driving machines which either perform work themselves or are very actively connected with the work performed, and machines engaged in con...

    W. S. Hadaway, Jr.: The paper by Messrs. McDowell and Mahood is of value in showing that while different types of heaters develop the same amount of heat with the same input, their effective value may vary according to conditions of service. View full abstract»

    C. R. Underhill: Mr. Kinsley is certainly to be congratulated on the very ingenious device which he has brought out, and I must say that it is one of the most surprising forms of high-speed printing telegraph instruments which have come to my notice It seems, however, that it is necessary to use two wires and ground, which makes the line expensive, particularly since the machine is designed, I pre...

    Morgan Brooks: I notice one point, that is not of very great importance, that perhaps might lead to error. The author speaks of the light varying inversely as the square of the distance. That is true in the case of point source, but not true of line source. If the light is of any appreciable length in proportion to the tank, or the vehicle which is used in conveying the water, it will vary more ne... View full abstract»
