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motors in improving the power factor of transmission plants, these latter machines are not likely to be entirely superseded.

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.

This book was released on 2017-06-04 with total page 506 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Canadian Electrical News and Engineering Journal Vol 15 written by UNKNOWN. AUTHOR and published by Forgotten Books. This book was released on 2015-06-16 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Canadian Electrical News and Engineering Journal, Vol. 15: January, 1905 The controller is mounted on the engineer's platform and has seven steps; it acts by connecting different resistances, in series, with the rotating part of the motor. These resistances are entirely separate from the machine, being connected with it by means of three slip rings. The mine incline varies from forty-five degrees to twenty degrees as depth is obtained. At present it has a depth of over 2,000 feet, and is equipped with double tracks of four feet gauge laid with 56 pound steel rails. The skips are self dumping and are not run in balance. These skips discharge into bins, the bottoms of which are about five feet above the tunnel track, which allows the cars running on the latter to be loaded through hoppers. The nominal speed of the hoist is five hundred feet a minute, but it has been found in actual practice that it only takes from five to six minutes for the skip to come from the bottom of the mine, discharge its load, and return again to the bottom. The total load hoisted (rope, skip and ore), is from 7 1/2 to 8 tons. The crushing plant is situated by the side of the railroad track, about three-quarters of a mile from the mouth of the tunnel. This plant is supplied with power by a branch from the main line, and the machinery at present consists of a 20 inch by 6 inch Farrel crusher with a set of geared rolls used for reducing the hard ore to fines. This hard ore occurs in parts of the mine but not in all. The two machines (crusher and rolls), are driven by a 50-horse power, 200 volt, slow speed, type C, Westinghouse induction motor, supplied through two 25 k. w. transformers. Electrical measurements indicate that these machines take about 40 h.p. when crushing eight tons per hour. This plant is only a temporary one, to be used until the new mill, now under construction, is completed. The new mill will be driven throughout by 2,000 volt motors. It is designed to handle all the ore from the mine, and will both drass the rich ore for shipping and crush and concentrate those ores which are too lean to ship. The hoist is so designed that, in case of accident, it may be operated by steam power by simply coupling an engine to each end of the countershaft of the new hoist, an operation which will require very little time. Steam will be supplied to the engines by old boilers, located about fifty feet away, the stacks from which consist of two tile pipes laid up the old shaft to the surface above. The old compound steam, single stage air compressor, built by the Canadian Rand Drill Company, which is located just over the mouth of the adit tunnel, can be used in the case of low water, or, of accident to the electrically driven compressor. Steam is supplied to this old compressor by the two 125 h.p. boilers which formerly ran it. In a recent test of the new plant it was found that, when double the full load was on the generators (a 100 per cent, overload test) the level of the water in the stand pipe was below its normal point, and that the water in the tail race was above the normal point; these water levels, both above and below, fluctuated rapidly and it was difficult to gauge them accurately with the means which were on hand at the time of the test. The actual head of water on the turbines is supposed to have been thirty-three feet, and if this assumption is correct the water wheels would have used, theoretically, 706 horse power of water, of which amount about 18 h.p. was consumed in the exciting generator. Allowing the main generator to have used 688 h. p. and on the assumption that it developed one hundred ampere per phase at a voltage of 2,160, and on the further assumption that the efficiency of the generator at this overload was 92 per cent., and that the power factor of the circuit (water rheostat) was unity, the brake horse power developed would have been about 543 h.p., which would give a...

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electrical News and Engineering, Vol. 20 The arbitrators appointed as a board of conciliation to settle the disputed matters in connection with the Winnipeg Street Railway Company and its four men who were dismissed for drinking while in uniform, have handed out decisions in the form of majority and minority reports. The majority report is submitted and signed by W. J. Christie, chairman, and Captain William Robinson, acting for the company. The minority report is submitted and signed by Mayor Peltier, of Port Arthur, acting for the men. The clause on which the decision mainly hangs is as follows: Entering any place where intoxicating liquors are sold as a beverage, while in uniform or while on duty, except in case of necessity. The majority report sustains the action of the company in dismissing four men for drinking while in uniform, claiming that the clause is clear and admits of only one interpretation. The minority report submits that the rule violated was not generally enforced and recommends the reinstatement of the men.
