B and C (p. 199) are large looking-glasses mounted as plain reflectors, the lower one C having rotary motion upon the saddle, resting upon the sill of the window in order to direct the rays of the sun upon the reflector B, at any hour of the day--the vertical motion of the reflector C英文原著 · 《American Hand Book of the Daguerreotype》

Approaching the door, Claude stopped a moment and peered in at the kitchen window. The table was set for supper, and Mahailey was at the stove, stirring something in a big iron pot; cornmeal mush, probably,--she often made it for herself now that her teeth had begun to fail. She stood leaning over, embracing the pot with one arm, and with the other she beat the stiff contents, nodding her head in time to this rotary movement. Confused emotions surged up in Claude. He went in quickly and gave her a bearish hug.英文原著 · 《One of Ours》
Then had come Robert Hoe's double-cylinder, steamdriven printing press. But a swifter machine was wanted. And so in 1845 Richard March Hoe, a son of Robert Hoe, invented the revolving or rotary press, on the principle of which larger and larger machines have been built--machines so complex and wonderful that they baffle description; which take in reels of white paper and turn out great newspapers complete, folded and counted, at the rate of a hundred thousand copies an hour. American printing machines are in use today the world over. The London Times is printed on American machines.英文原著 · 《The Age of Invention》
Henry next turned to the possibility of a magnetic engine for the production of power and succeeded in making a reciprocating-bar motor, on which he installed the first automatic pole changer, or commutator, ever used with an electric battery. He did not succeed in producing direct rotary motion. His bar oscillated like the walking beam of a steamboat.英文原著 · 《The Age of Invention》
Another interesting consequence of Sir William Thomson's pregnant hypothesis is that the absolute hardness which has been 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 its motion.英文原著 · 《The Unseen World and Other Essays》
