"Piston" Quotes from Famous Books



... this: If you double your fist this way, and tuck your thumb alongside, like that, and aim for this spot right here, about two inches this side of the chin, bringing your arm back, and up, quickly, like a piston, the person you hit will go down, limp. There's a nerve right here that communicates with the brain. That blow makes you see stars, bright lights, and fancy colors. They use ...

... a strong iron chest, with a hinged cover, into which the clay is placed, having a piston moving in it, connected by a rod or bar, having cog-teeth, with a cog-wheel, which is moved by horse or hand power, and drives the piston forward with steadiness, forcing the clay through the openings in the die-plate. The clay issues in continuous ...

The expected party sailed from Liverpool the 26th of May, on the America After being out three days the piston rod broke and they were obliged to return. My son-in-law, W.H.

... exhaust stroke, had not entirely evacuated all of the products of combustion. The Atkinson engine, patented in 1887, was one of the attempts to solve this as well as several other problems, thus creating a more efficient cycle. This engine was designed so that the exhaust stroke carried the piston all the way to the head of the engine, while the compression stroke only moved the piston far enough to sufficiently compress the mixture. The unusual linkage necessary to create these unequal strokes in the Atkinson engine made ...

... objection may be reduced by using the air in a state of compression, and therefore of greater density, throughout its operation. Even then, however, the amount of operative heat is very small in comparison with that which passes through the steam-engine, per cubic foot swept through by the piston, for the change of state which water undergoes in its transformation into steam involves the taking in of much more heat than can be communicated to air in changing its temperature within such a range as is practicable. Another and not less serious objection is the practical ...

There must be enough play between the vital parts to allow of some movement; "dither" ...

These are commonly lost or stolen before the maccaroni arrives among us.

... offered to the notice of the world," he wrote, in 1833, "none have stood the test of practical use and experience. The cause of this uniform failure has been the great difficulty of obtaining, within the machine, a base of resistance on which the steam might act in propelling the moveable piston." He did not quite overcome this difficulty, but he succeeded in producing what the foremost critic in this department of manufacture describes—after a lapse of thirty years unrivalled for their development of ingenuity—as "the most perfect ...
