Hydraulic   Listen
adjective
Hydraulic  adj.  Of or pertaining to hydraulics, or to fluids in motion; conveying, or acting by, water; as, an hydraulic clock, crane, or dock.
Hydraulic accumulator, an accumulator for hydraulic machinery of any kind. See Accumulator, 2.
Hydraulic brake, a cataract. See Cataract, 3.
Hydraulic cement, a cement or mortar made of hydraulic lime, which will harden under water.
Hydraulic elevator, a lift operated by the weight or pressure of water.
Hydraulic jack. See under Jack.
Hydraulic lime, quicklime obtained from hydraulic limestone, and used for cementing under water, etc.
Hydraulic limestone, a limestone which contains some clay, and which yields a quicklime that will set, or form a firm, strong mass, under water.
Hydraulic main (Gas Works), a horizontal pipe containing water at the bottom into which the ends of the pipes from the retorts dip, for passing the gas through water in order to remove ammonia.
Hydraulic mining, a system of mining in which the force of a jet of water is used to wash down a bank of gold-bearing gravel or earth. (Pacific Coast)
Hydraulic press, a hydrostatic press. See under Hydrostatic.
Hydraulic propeller, a device for propelling ships by means of a stream of water ejected under water rearward from the ship.
Hydraulic ram, a machine for raising water by means of the energy of the moving water of which a portion is to be raised. When the rush of water through the main pipe d shuts the valve at a, the momentum of the current thus suddenly checked forces part of it into the air chamber b, and up the pipe c, its return being prevented by a valve at the entrance to the air chamber, while the dropping of the valve a by its own weight allows another rush through the main pipe, and so on alternately.
Hydraulic valve. (Mach.)
(a)
A valve for regulating the distribution of water in the cylinders of hydraulic elevators, cranes, etc.
(b)
(Gas Works) An inverted cup with a partition dipping into water, for opening or closing communication between two gas mains, the open ends of which protrude about the water.

... together, and of immense strength. The center of this wooden disc was hollowed out to a diameter equal to the exterior diameter of the Columbiad. Upon this wheel rested the first layers of the masonry, the stones of which were bound together by hydraulic cement, with irresistible tenacity. The workmen, after laying the stones from the circumference to the center, were thus enclosed within a kind of well twenty-one feet in diameter. When this work was accomplished, the miners resumed their picks and cut away the rock from ...

... as public-houses. Lumpers also smuggle goods ashore for the crews of vessels. The smuggling of tobacco is so considerable, that it is well worth the while of the sellers of smuggled tobacco to use hydraulic presses, to squeeze a single pound into a package small enough to be contained in an ordinary pocket. Next, said my friend Pea, there were the Truckers - less thieves than smugglers, whose business it was to land more considerable parcels of goods than the Lumpers ...

... uncouth-looking vehicles, used as public conveyances. Still it was on a Lilliputian scale as compared to London, and semi-barbarous even as compared to one of our towns. Marly-la-Machine was passed; an hydraulic invention to force water up the mountains to supply the different princely dwellings of the neighbourhood. Then came a house of no great pretension, buried in trees, at the foot of the bill. This was the celebrated consular abode, Malmaison. After this we mounted to a hamlet, and the road ...

... substance with the property—rather a startling one, it is true—that its area diminishes in proportion to the amount of wishes gratified, and vanishes with the death of the possessor. The steady flesh-and-blood men of science treat it just as we feel certain that they would do. After smashing a hydraulic press in the attempt to compress it, and exhausting the power of chemical agents, they agree to make a joke of it. It is not so much more wonderful than some of those modern miracles, which leave us to hesitate between ...

... in agriculture is twofold; the first is the real increase in the productive output per person in agricultural industry. In larger part this is due to the increasing use of machinery in place of simple hand tools, and the substitution of horse-, hydraulic-, windmill-, steam-, and gasoline-power for human labor. This change has been made readily in the regions of level fields, but of late has been made possible to a greater extent in hilly country, by rearranging and combining the old irregular fields into regular fairly level ...

The story tells itself in the biographical preface to his poem. He went to London with the view of introducing a hydraulic machine, which he and his Vermont friends regarded as a very important invention. He found, however, that the machine was already in common use in that metropolis. A brother Yankee, then in London, had started the project of a mill, which was to be carried by the water of the Thames. ...

The former only separates a solid mass into a great number of smaller masses; and for these purposes various species of forces are employed, according to circumstances, such as the strength of man or of animals, the weight of water applied through the means of hydraulic engines, the expansive power of steam, the force of the wind, &c.
