Book excerpt: Excerpt from Canadian Electrical News and Steam Engineering Journal, 1891, Vol. 1 Now let us assume that an error of 50 pounds was made in weighing the water, so that the apparent amount of water evaporated was pounds, instead of pounds, the actual amount. So that the apparent evaporative performance of the boiler is pounds of water per pound of coal, instead of pounds, which is the correct result. The difference introduced by an error of fifty pounds in weighing the water, it will be seen, is only 02. Now let us make-a different supposition. Let us assume that the water was weighed correctly, but that an error of fifty pounds was made in weighing the coal, the apparent weight of coal being pounds. Then so that the ap parent evaporative performance of the boiler is pounds of water per pound of coal, instead of the true result, pounds. The difference in this case is quite appreciable, and the example shows that it makes quite a difference whether a given error is made in weighing the coal or in weighing the water.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Canadian Electrical News and Steam Engineering Journal, Vol. 9: January, 1899 Rope transmission. - In a paper on power transmission by ropes and belts, read before the French Society of Civil Engineers, V. Dubreuil states that one great advantage possessed by ropes is that cyclical variations in the speed of the driving pulley are damped by the ropes, so that the speed of the driving pulley is much more uniform than that of the driver. Ropes are also useful when the two lines of shafting are not peifectly parallel. The velocity of the rope should not be less than about feet per minute, nor more than feet, while with belts a velocity of as little as 600 feet per minute may be used, but the maximum should not exceed feet per minute, above which the centri fugal force prevents the proper adhesion of the belt to the pulley. For great distances between the lines of shafting ropes should be used; though in exceptional cases they may be employed with as little as 12 feet between shaft centres, in general the distance should not be less than 20 feet. Spans of as much as 328 feet have been worked by ropes with only intermediate support. Under no circumstances should the diameter of the smallest pulley be less than 30 times the diameter of the rope, and in general the pulley ratio should not be greater than four to one. Three standard ropes of manila, hemp or cotton may be used. Hemp is much cheaper than cotton, and usually wears longer, but is less pliable. To facilitate estimates, the approximate weight ofa rope pulley may be taken as 5% pounds per groove for each inch of diameter, though single groove pulleys will weigh double this amount.

Book excerpt: Excerpt from Canadian Electrical News and Engineering Journal, 1900, Vol. 10 The induction motor has come into wider and wider use as transmission plants have increased in number, and particularly the larger sizes have been well developed. These very large induction motors are particularly valu able for hard service and starting with considerable loads, although in view of the value of synchronous motors in improving the power factor of transmission plants, these latter machines are not likely to be entirely superseded.

Book excerpt: Excerpt from Canadian Electrical News and Engineering Journal, 1902, Vol. 12 At the station at Cornwall a large circle of twenty poles had been set up, each one of which is 150 feet high and bears an aerial wire. The electric force that is sent out from this transmitting station is said to be one hundred times greater than that at the ordinary wireless telegraph station. When a permanent station is installed on this side Marconi will not be dependent upon uctuations of the wind, and he is confident Of making the signals strong and reliable, that is, not requiring such delicate and sensitive receiving instruments, by employing much greater power at the sending station.

Download or read book When Old Technologies Were New written by Carolyn Marvin and published by Oxford University Press. This book was released on 1990-05-24 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of electronic communication, the last quarter of the nineteenth century holds a special place, for it was during this period that the telephone, phonograph, electric light, wireless, and cinema were all invented. In When old Technologies Were New, Carolyn Marvin explores how two of these new inventions--the telephone and the electric light--were publicly envisioned at the end of the nineteenth century, as seen in specialized engineering journals and popular media. Marvin pays particular attention to the telephone, describing how it disrupted established social relations, unsettling customary ways of dividing the private person and family from the more public setting of the community. On the lighter side, she describes how people spoke louder when calling long distance, and how they worried about catching contagious diseases over the phone. A particularly powerful chapter deals with telephonic precursors of radio broadcasting--the "Telephone Herald" in New York and the "Telefon Hirmondo" of Hungary--and the conflict between the technological development of broadcasting and the attempt to impose a homogenous, ethnocentric variant of Anglo-Saxon culture on the public. While focusing on the way professionals in the electronics field tried to control the new media, Marvin also illuminates the broader social impact, presenting a wide-ranging, informative, and entertaining account of the early years of electronic media.
