"Rotary motion" Quotes from Famous Books
 ... wallop somebody, are you?" spoke Clark cooly. "Watch the system-cylinder"—and the speaker gave to his arms a rotary motion so rapid that it was fairly dizzying, "or piston rods," and one fist met the bulging breast of the fellow with a force that sent ...

... although in its details it more or less resembles the analogous machines of Schoenherr, Crompton, and Hartmann. The lifting of the shuttles is effected by two sectors, a1, a2, arranged on the two sides of the loom, and the rotary motion of which acts upon the box, c, by means of the lever, b, the box being caused to descend again by the spring, d. Parallel with the breast beam there is mounted an axle, e, and upon one of the extremities of this is fixed the sector, a1, while the other extremity carries two ...

... have been a vastly convenient thing for humanity had it chanced that the earth had so accommodated its rotary motion with its speed of transit about the sun as to make its annual flight in precisely 360 days. Twelve lunar months of thirty days each would then have coincided exactly with the solar year, and most of the complexities of the calendar, which have ...

... 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 ...

... devices used in particular machines—such as a ratchet device for a numbering machine, a locking index for gunmaking machinery, and a few gear trains—the great majority were for converting reciprocating motion to rotary motion. Even a cursory examination of these patents reveals an appalling absence of sound mechanical sense, and many of them appear to be attempts at "perpetual motion," in spite of an ...

... 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 ...

... the bowl with a rotary motion, and when Doc arrived with the pan, nursed the sand out into it, and as the last of the sand went over the lip of the bowl, ran out on deck into the sun, and examined the bottom ...

... obtained a grant of the monopoly of steam-navigation from the State of New York. Fulton took out two patents for his invention; but unfortunately they were not adequate to his protection, for they covered only the application of the steam-engine to the turning of a crank in producing the rotary motion of the paddle-wheels. ...

... 6500 English feet, they commenced their observations. The magnetic needle was attracted as usual by iron, but it was impossible for them at this time to determine with accuracy its rate of oscillation, owing to a slow rotary motion with which the balloon was affected. The voltaic pile exhibited all its ordinary effects, giving its peculiar copperas taste, exciting the nervous system, and causing the decomposition of water. At the elevation of 8600 feet, the animals ...

... relating to motion. Two substances brought within the range of chemical affinity unite with more or less violence; the motion of transition of the particles is transformed, wholly or in part, into a vibratory or rotary motion, either of the particles themselves or the interatomic ether; and according to the quality of the motions we are as a rule, besides other effects, made conscious of heat or light, or of both. When these emanations come ...
