... through a night of tempestuous wind with the open window at my head. I awoke and saw myself face to face in my weakness. It rained all day. ... I can hardly bear my love today. It is a terrific dynamo of silence. But it will be very long before I shall fulfill my worthiness. If one could always remember that he is a saviour, and carry humanity with him, his will would be inflexible and every act an exulting humility. All nature is but a mantle which ...

... 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 ...

Salvation Jim was full of device and resource, the Prodigal, a dynamo of eager energy; but it was the Jam-wagon who proved his mettle in a magnificent and relentless way.

Where they stopped they wintered, building cabins and starting "towns." In one or two cases the "towns" were electrically lit from the steamboat's dynamo. The next summer they all left, all save those who were wrecked by the ice, and the "towns" were abandoned. But they had got upon the map through some enterprising representative of the land office, and they figure on some recent maps still. ...

... act, all man's work ends there;—mathematics, physics, chemistry, dynamics, optics, every sort of machinery science may invent,—to this favour come at last, as religion and philosophy did before science was born. All that the centuries can do is to express the idea differently:—a miracle or a dynamo; a dome or a coal-pit; a cathedral or a world's fair; and sometimes to confuse the two expressions together. The world's fair tends more and more vigorously to express the thought of infinite energy; the great cathedrals ...

Almost all the electrical arts now employed made their beginnings in the next twenty-five years, and while the more extensive of them depend to-day on the dynamo for electrical energy, some of the most important still remain in loyal allegiance to the older source. The battery itself soon underwent modifications, and new types were evolved—the storage, the double-fluid, and the dry. Various analogies next pointed to the use of heat, and the thermoelectric ...

To be more explicit, a submersible has a mechanical process, a combination motor and dynamo between the engine, which drives the boat when it is on the surface, and the thrust block through which the shaft runs to the propeller. This motor-dynamo, serving as a motor, drives the boat when she is beneath the water. When the electric power is exhausted the boat comes to the surface, ...

Incidentally these storage reservoirs, by increasing the surface exposed to evaporation and the consequent rainfall, have a very beneficial effect on the dry regions in the interior of the continent, and in some cases have almost superseded irrigation.

Then Faraday discovered that an electric current could be generated in a wire by the motion of a magnet, thus laying the basis for the modern dynamo. Professors Gauss and Weber, who were operating the telegraph line at Goettingen, adapted this new discovery to their needs. They sent the message by moving a magnetic key. A current was thus generated in the line, and, passing over the wire and through a coil at the farther end, moved a magnet ...
