... question of alternating currents, the work done in connection with the two-phase and three-phase currents and the perfection of the rotary transformer has resulted in introducing into central station practice a further means of economizing the cost of production—by concentration of power. According to present experience, it is (except in some extraordinary cases) uneconomical ...

... an aggregation of subtile matter, no crust could be solidified on the outer ring, and then detached from the mass within; indeed, any separation of the parts under such circumstances is inconceivable. Even a rotary motion could not be established in it, except by an impulse received from without; for there is every reason to believe, that the movement of a homogeneous fluid towards its centre, if it could take place without disturbing causes, would ...

Another method is to mill once and transfer the mass to a rotary mixing machine, fitted with internal blades, of a peculiar form, which revolve in opposite directions one within the other as the mixer is rotated. The perfume, colouring matter, etc., are added and the mixer closed and set in motion, when, after a short time, the soap is reduced ...

... reasonable, however bad it may look, that this is the way he is made, that in proportion as he does his knowing spiritually and powerfully, he will have to do it dramatically. It sometimes seems as if knowing, in the best sense, were a kind of rotary-person process, a being everybody in a row, a state of living symposium. The interpenetrating, blending-in, digesting period comes in due course, the time of settling down into himself, and behold the man is made, a unified, concentrated, ...

... is obtained by terrific speed of the moving parts, as though a steam engine, to avoid great pressure in its cylinders, had a long stroke and ran at great piston speed, which, however, is no disadvantage to the rotary motion of the electric motor, there being no reciprocating cranks, etc., that must be started and stopped at each revolution. "To obviate the necessity of gearing to reduce the number of revolutions to those possible for a large ...

... the angle at which the cylinders were set. The Nasmyth drawing alters the whole aspect of the question, and we are now left to speculate as to what became of the original Rocket. We are told that after "it" left the railway it was employed by Lord Dundonald to supply steam to a rotary engine; then it propelled a steamboat; next it drove small machinery in a shop in Manchester; then it was employed in a brickyard; eventually it was purchased as a curiosity by Mr. Thomson, of Kirkhouse, near Carlisle, ...

... facts connected with the Trades, and with the Monsoons, or trade-winds turned back by continental heat in the East Indies, the Typhoons, the Siroccos, the Harmattans, land and sea breezes and hurricanes, the Samiel or Poison Wind, and the Etesian. The Cyclones, or rotary hurricanes, offer a most inviting field for observation and study, and are an important branch of our subject. But we are obliged to omit the consideration of these topics, to be taken up, possibly, at some other opportunity. The theory of the Cyclones may be justly considered as original ...

... attributed to material atoms from the time of Lucretius downward may be dispensed with. Somewhat in the same way that a loosely suspended chain becomes rigid with rapid rotation, the hardness and elasticity of the vortex-atom are explained as due to the swift rotary motion of a soft and yielding fluid. So that the vortex-atom is really indivisible, not by reason of its hardness or solidity, but by reason of the indestructibleness of ...

... example, the printing-press: No one can question the immense advantages which have flowed from the increased facility for transmitting ideas. But may it not be true that the thousandfold increase in such transmission by the rotary press has also tended to muddy the current thought of the time? True it is that the printing-press has piled up great treasures of human knowledge which make this age the richest in accessible information. I am not speaking of knowledge, but rather ...

... McCormick and his competitors, Samuel F. B. Morse had perfected his electric telegraph, which was in operation in most of the countries of Europe before 1860. Richard M. Hoe revolutionized newspaper publishing in the late forties by his rotary printing-press, which put out thousands of copies of a paper in an hour. Nor was Elias Howe's sewing-machine any less of a wonder when it came into use about 1850. Draper and Morse's new photography, Thurber's typewriter, Woodruff's sleeping-car, and many other marvelous contrivances ...

When they did so, Carroll, glancing down again through the scuttle, could not flatter himself that he had reduced the water. It was comforting, however, to see that ...

... practicable. Count Zeppelin gained an advantage by attaching his propellers to the balloon, instead of to the car as heretofore; but this requires a rigid framework and a great increase of weight. Le Compagnon endeavoured, in 1892, to substitute flapping wings for rotary propellers, as the former can be suspended near the centre of resistance. C. Danilewsky followed him in 1898 and 1899, but without remarkable results. Dupuy de Lome was the first to estimate in detail the resistances to balloon propulsion, but experiment ...

In the middle of one of the longest sentences, he stopped the rotary motion of the snuffbox, raised his head, and with inimical politeness lurking in the corners of his thin lips interrupted Weyrother, wishing to say something. But the Austrian general, continuing to read, frowned angrily and jerked his elbows, as ...

... has merely to depress this pedal with his foot, when the box is opened and the whole of the contents are released. The fall at first is somewhat erratic, but this is an advantage, as it enables the darts to scatter and to cover a wide area. As the rotary motion of the arrows increases during the fall, the direct line of flight becomes more pronounced until at last they assume a vertical direction free from all wobbling, so that when they alight upon the target they ...

We can but theorize that the pole, being several miles in diameter, hurled us from its edge, the tremendous repelling force not permitting our aerenoids to proceed over its surface. The rotary motion of the planet upon its axis would then cause us to describe a curve in our flight from its surface, as only in the center of the pole would this rotary motion lose ...

Lie on your back with legs straight before you, feet together, arms close at your sides, and head thrown back; trust the water to bear you up and all that is necessary to keep you afloat is a rotary motion of your hands under water. After a time all movement may be given up and you will lie easily and quietly as on a bed. It is said that it is easier for women and girls to float than for men, because their bones are lighter, and some learn to float the first time ...
