"Dynamo" Quotes from Famous Books



... from native land, Karl was a real menace to constituted authority. Speech led him into proscribed provinces. Harmless in overt act or intent, his words were deadly explosives, charged with dynamo energy sufficient to wreck every ...

... scarred with dotted lines from a dressmaker's tracing-wheel, and to set it with an embroidered lunch-cloth, and the mauve-glazed Japanese tea-set which she had brought from St. Paul. Miss Sherwin confided her latest scheme—moral motion pictures for country districts, with light from a portable dynamo hitched to a Ford engine. Bea was twice called to fill the hot-water pitcher and to make ...

... see it by leaning far out of the window; and it would not have come to their attention at all had they not heard it first—or, rather, heard the sound of something within it: for from it came a curious whining hum that never varied in intensity, something like the hum of a gigantic dynamo, only greater and of a more ...

... cannot be explained in intellectual terms. As Confucius said long ago: "When we are so ignorant of life, can we know death?" And ignorant of life we truly are when we cannot explain it in terms of the understanding. We know life only phenomenally, as a savage may know a dynamo; but we know nothing of life noumenonally, nothing of the nature of the intrinsic stuff ...

... I'm the commander. Lift that baby down to the skipper's room with the sick woman, and let them nurse each other. Lift Jenkins out of the wardroom, and stow him in a forecastle bunk. Riley, nurse your engines and save oil, but keep the dynamo going for the wireless; and you, Casey, have you got that message ...

They are 42 feet in height, the diameter of the revolving part is 32 feet, its weight, 332,000 pounds, and the aggregate weight of the machine, 889,000 pounds. The design of the engine dynamo unit eliminates the auxiliary fly wheel generally used in the construction of large direct-connected units prior to the erection of the Manhattan plant, the weight and dimensions of the revolving alternator field being such with reference to the turning ...

... after waving farewell 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. At one end were the heating furnaces, their doors open, and gentle fires glowing softly within to slowly raise the temperature of newly set brick. Around him was the swing of work directed by skilled brains, and machinery moved slowly into its appointed place of ...

... 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 ...

It was lighted, but a sharp cool air and the fret of the river came in through a black opening in one wall. Laura sat upon a large deal case, and Nasmyth, looking down upon her, leaned against a dynamo. He smiled as he recognized that she grasped the significance of ...

... "harnesses" move part of the warp 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 ...

... exhibited from some buoys in the United States. In England an automatic electric buoy has been suggested, worked by the motion of the waves, which cause a stream of water to act on a turbine connected with a dynamo generating electricity. Boat-shaped buoys are also used (river Humber) for carrying a light and bell. The Courtenay whistling buoy (fig. 13) is actuated by the undulating movement of the waves. A hollow cylinder extends from the lower part of the buoy to still water below the movement ...

... of the materials consumed, for a 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 ...

... communicates with an air pump, is opened, and the pressure is diminished to about 730 mm. of mercury. At this moment the oxidizing apparatus are put in communication with an induction bobbin that is interposed in the circuit of a dynamo, while through the tube, n, there is made to enter a mixture of equal parts (in volume) of sulphurous acid, oxygen, and air. At the same time, the cock of the tube, g, is opened, while the stirrer, T, is set in motion. In this way we obtain, in a much shorter time than by ordinary processes, ...

The machinery of an old grist mill is used to operate a small dynamo, which charges a storage battery and furnishes light for the fish industry there. Another wheel in the same mill works an ice making machine, the whole being under the charge of one man. It is stated that the total daily expense for generating ...

... any of the number. It showed that we were going down, down, down, literally down to the sea in a ship. When we had been submerged far more than an hour, and there was thirty feet of yellowish green ocean over our heads, Mr. Lake suddenly ordered the machinery stopped. The clacking noises of the dynamo ceased, and the electric lights blinked out, leaving us at once in almost absolute darkness and silence. Before this, we had found it hard to realize that we were on the bottom of the ocean; now it came upon us suddenly and not ...

... represent one type of energetic phenomena, no matter what is the origin of each. For example, a galvanic or chemical battery produces the same kind of electricity as the mechanical process of friction or the interaction of cosmic laws as in the dynamo. In some instances, when our systems are suitably adjusted, the transformations are reversible, that is, the energy results in a chemical process—an accumulator; the chemical process results in electricity—the galvanic battery; motion results in electricity—the ...

When this material, mixed with the oxide to be reduced, was made a part of the electric circuit in a fire clay retort, and submitted to the action of a current from a powerful dynamo machine, not only was the oxide reduced, but the temperature increased to such an extent that the whole interior of the retort fused completely. In other experiments lumps of lime, sand, and corundum were ...
