We have calculated armatures and field coils for the new dynamo with Upton, and held the stakes for Jehl and his fellows at their winding bees. We have seen the mineral and vegetable kingdoms rifled and ransacked for substances that would yield the best "filament." We have had the vague consciousness of assisting at a great development whose evidences to-day on every hand attest its magnitude.
The most prominent instance of this is the new utilization of Niagara as a turbine water-power with which to whirl the armatures of gigantic dynamos, using the power thus obtained upon motors, and in the production of light and the transmission of power to neighboring cities.
"But that was Keith, not I, in the case of John McGuire." "It was you at the last," corrected the girl gently. "Mr. Burton, John McGuire wouldn't have any book out this spring if it weren't for you and your eyes." "Hm-m, perhaps not. Still there'd have been a way, probably. But even if I grant that all you say in the case of John McGuire that isn't winding armatures, or whatever they are." "Mr.
If both transmitters be closed simultaneously, both batteries will be placed to the line, which would practically result in doubling the current in each of the main-line coils, in consequence of which both relays are energized and their armatures attracted through the operation of the keys at the distant ends.
In the modern "dynamo" we cannot help having friction at the bearings and contact pieces, it is true, but there should be no other friction. The moving coils of wire or "armatures" should rotate freely without touching the iron pole-pieces of the fixed portion of the machine. In fact friction would be fatal to the action of the "dynamo." How then does it act?
The armatures are powerfully attracted by the magnets, and must be forcibly pulled away. Indeed, one of Wilde's machines, when producing a very intense electric light, required about five horse power to drive it." Thus was the secret in regard to electric power unconsciously divulged some twenty years ago. In all nature there is no recipe for getting something for nothing.
The electromotor was invented by Professor Jacobi; it virtually consisted of two disks, one of which was stationary, and carried a number of electromagnets, while the other disk was provided with pieces of iron serving as armatures to the pole pieces of the electromagnets, which were attracted while the electric current was alternately conveyed through the bobbins by means of a commutator, producing continuous rotation.
He's experimented continually at your expense; he's bungled the job from beginning to end with his carelessness his 'good enough' work. "You were queered from the start with them armatures he wound back there on the Coast. He and Jennings took an old fifty horse-power motor and tried to wind it for seventy-five. There wasn't room for the copper so they hammered in the coils.
They also made optical glass; drilled and tapped in the shipyards; renewed electric wires and fittings, wound armatures; lacquered guards for lamps and radiator fronts; repaired junction and section boxes, fire control instruments, automatic searchlights.
The symbol is, as we see, repeated a great many times. Every seal has been dotted or crossed on some one of the lines composing it; some seals are coupled with brackets and armatures." "What of it?" inquired Harren vacantly. "Well, sir, in the first place, that symbol is supposed to represent the spiritual and material, as you know. What else do you know about it?" "Nothing.
