"Dynamo" Quotes from Famous Books



... our progress need not come by slow revolutions. We must foster all those peaceful revolutions of ideas that will result in social justice. Just as we accept the latest inventions in mechanics, industry, and art, such as the automobile, the dynamo, and the aeroplane, so must we accept the latest improvements in the social and political institutions ...

... and is a compound condensing horizontal tandem, made by Messrs. Pollitt & Wigzel, of Sowerby Bridge. The fly wheel of this engine is 20 feet in diameter, and weighs 30 tons, and is geared to the pulley of the dynamo, so that the latter makes five revolutions for each revolution of the engine by rope driving gear, consisting of eighteen ropes. The engine is an extremely fine specimen of a modern steam engine; it works so silently that a visitor standing with his back to the engine railings, at the time the engine ...

... large question!" said Fillmore. "At different times since the commencement of our work, we have used three methods for generating electricity. First, the old fashioned steam dynamo. Second, the direct conversion of coal into electricity. Third, the gathering of great quantities of this subtle force from the atmosphere, through a certain vibratory action, set up by intense concentration of the sun's rays. As a result of a vast deal of co-operative thinking and careful ...

... by a chain of the same material, was used for this purpose. A powerful coil steel spring operated the windlass. In each of the other corners of the room were anchors of aluminum, also attached to windlasses and worked by steel springs. There was a dynamo that afforded abundance of light for the ship. This, too, was run by spring power. The rooms of the cabin were brilliantly lighted, and the spiral stairway, from the foot of the mast which stood upon the center of the floor ...

... back helplessly. Fowler placed it in position each time, marking each new position, while I took note of the convulsive tremor which swept from time to time over the psychic. It was exactly as if she were a dynamo generating some unknown electrical energy, which, after accumulating for a time in her organism (as in a jar), was discharged along the direction of our will, and yet I could not detect any marked synchronism ...

... to the new laboratory I noticed that the majority of the students were, in one way or another, giving attention to matters connected with electricity. There had already been built in the machine-shops, under the direction of Professor Anthony, a dynamo which was used in lighting our grounds, this being one of the first examples of electric lighting in the United States; and on one of my visits I said to him, "It looks much as if, with the rapid extension throughout the country of the telegraph, telephone, electric lighting, ...

... now up, now down, and the shuttle carries the weft from side to side to be driven home by the reeds to the woven cloth. Our grandmothers did all the work with swift movements of hands and feet. The modern weaver has her loom harnessed to the electric dynamo and moves her fingers only to keep the threads in order. If she wishes to weave a pattern in the cloth, no longer does she pick up threads of warp now here, now there, according to the designs. It is all worked out for her on the loom. Each thread ...

The colony droned like some huge dynamo with the rumour of secret preparation against the night. Other than servants scurrying to and fro on pressing but mysterious errands, few folk were visible in the afternoon; the drives and beaches; the lawns, terraces, courts, gardens, ...

... machine of this kind ever to be employed for industrial purposes. If, however, the electric current, instead of being developed by chemical work in a battery, is produced by ordinary mechanical power in a magneto-electric or dynamo-electric machine, the case is different; and the double transformation, first of the mechanical force into an electric current, and then of that current into mechanical force, furnishes a means for effecting the conveyance of the power to ...

... of our storerooms was rapidly fitted up as an impromptu radiographic department, the windows painted over and covered with thick paper, a stove introduced, and a dark-room contrived with the aid of a cupboard and two curtains. Electric current was obtained from a dynamo bolted on to the step of a twenty-horse-power car, and driven by a belt from the flywheel of the engine. The car stood out in the courtyard and snorted away, whilst we worked in the storeroom alongside. The coil and mercury break were ...

For, the electric current that passes from each of you to the machine over these wires carrying the record of the secrets of your hearts is one of the feeblest currents known to science. Yet it can be caught and measured. The dynamo which generates this current is not a huge affair of steel castings and endless windings of copper wire. It is merely the heart of ...

The first dynamo grew and grew and grew and to-day it provides us with heat and with light ...

... at the big gates of the works, had gone into the rail mill and stood in the shadow in deep contemplation. He glanced at the massive flywheel, the great dominant dynamo and the huge, inflexible rolls.

Around him was the swing of work directed by skilled brains, and machinery moved slowly into its appointed ...

On February 4, 1867, he published the principle of reaction in the dynamo-electric machine by a paper to the Royal Society; but Mr. C. W. Siemens had communicated the identical discovery ten days earlier, and both papers were read on the same day. It afterwards appeared that Herr Werner Siemens, Mr. Samuel Alfred Varley, and Professor Wheatstone had independently arrived ...

... succumbed to his charm. He dominated that little dining-room because he was a sixty-horse-power dynamo. For all his bulk he was as lean as a panther and as sinewy.

Dominico and Dowst connected the wires from the rocket head to a reel of wire and rolled it toward the crater.

... You meet them everywhere, each Supply Column a self-contained unit like a fleet. It has its O.C., its cooks, its seventy-two motor lorries, with three men to each, and its "mobiles" or travelling workshops with dynamo, lathe, drilling machine, and a crew of skilled artificers, ready to tackle any motor-lorry that is put out of action. I take off my hat to those handy-men; many times have they helped me out of a tight place and performed delicate operations on the ...
