She could feel the blood pumping in her neck.
An unbelievable amount of blood was pumping from a tiny cut on her hand.
For pumping a well a valved working-barrel with valved sucker is attached to the lower end of the tubing, a perforated " anchor " being placed below.
The tidal action of the gulf is so slight and the marshes are so low that perfect drainage cannot be obtained through tide gates, which must therefore be supplemented by pumping machinery when rains are heavy or landward winds long prevail.
Owing to the pumping of the brine for the salt-works there is a continual subsidence of the ground, detrimental to the buildings, and new houses are mostly built in the suburbs.
Their movement in an upward or downward direction in Limulus and Mygale must exert a pumping action on the blood contained in the dorsal arteries and the ventral veins respectively.
A mine should always be opened by drift or entry if practicable, as thereby the expense of hoisting and pumping is avoided.
A man-engine consists of two heavy wooden rods (like the rods of a Cornish pumping plant), placed parallel and close to each other in a special shaft compartment, and suspended at the surface from a pair of massive walking beams (or " bobs ").
Mine pumps are of two classes: (I) those in which the driving engine is on the surface and operates the pumps by a long line of rods passing down the shaft, commonly known as the Cornish system; (2) direct-acting pumps, in which the engine and pumping cylinders form a single unit, placed close to the point underground from which the water is to be raised.
Hydraulic pumping engines, while not differing essentially from steam pumps, must have specially designed valves in the power cylinder on account of the incompressibility of water.
The possibility of hoisting and pumping from great depths has been discussed, and it remains now to consider the other conditions which will tend to limit mining operations in depth - namely, increase of temperature and increase of rock pressure.
This is an expensive operation as it entails the cost of pumping the water out again and repairing the resulting damage.
But sufficient time must be allowed to elapse before pumping out the water, as otherwise the fire may break out again.
The larger part of the water supply, however, is now derived by pumping from strata at about sea-level.
This method necessitates the use of very considerable pumping power during the sinking, as the water has to be kept down in order to allow the sinkers to reach a water - tight stratum upon which the foundation of the tubbing FIG.
Since the accident at Hartley colliery in 1862, caused by the breaking of the pumping-engine beam, which fell into the shaft and blocked it up, whereby the whole of the men then at work in the mine were starved to death, it has been made compulsory upon mine-owners in the United Kingdom to have two pits for each working, in place of the single one divided by walls or brattices which was formerly thought sufficient.
In this the filling material, preferably sand, is sent down from the surface through a vertical steel pipe mixed with sufficient water to allow it to flow freely through distributing pipes in the levels commanding the excavations to be filled; these are closed at the bottom by screens of boards sufficiently close to retain the packing material while allowing the water to pass by the lower level to the pumping-engine which returns it to the surface.
These can, however, only be used advantageously where there are fixed pumps, the fall of water generating the power resulting in a load to be removed by the expenditure of an equivalent amount of power in the pumping engine above that necessary for keeping down the mine water.
In dip workings the tail rope is often made to work a pump connected with the bottom pulley, which forces the water back to the cistern of the main pumping engine in the pit.
Private irrigation by pumping was first successfully introduced about 1901, and in 1906 a state report estimated that 125 pumping irrigation plants were in use in the state.
Other parks are Lake Park, also on the lake shore, at North Point, where stands the waterworks pumping station with its tall tower; Riverside and Kilbourn Parks, east and west respectively of the upper Milwaukee river, in the northern part of the city, Washington Park on the west side, containing a menagerie and a herd of deer; Sherman Park on the west side, and Kosciusko, Humboldt and Mitchell Parks on the south side.
This provides for taking water from the Ohio river at a point on the Kentucky side opposite the village of California, Ohio, and several miles above the discharge of the city sewers; for the carrying of the water by a gravity tunnel under the river to the Ohio side, the water being thence elevated by four great pumping engines, each having a daily capacity of 30,000,000 gallons, to settling basins, being then passed through filters of the American or mechanical type, and flowing thence by a gravity tunnel more than 4 m.

In this way jelly-fish progress feebly by the pumping movements of the umbrella.
Owing to the pumping of the brine, large tracts of land have been submerged, and there is thus a constant danger to houses.
The cultivation of the cane was greatly encouraged by the Reciprocity Treaty of 1875, which established practically free trade between the islands and the United States, and since 1879 it has been widely extended by means of irrigation, the water being obtained both by pumping from numerous artesian wells and by conducting surface water through canals and ditches.
By the close of 1861 wells had been drilled from which 2000 to 3000 barrels flowed in a day without pumping, and the state's yearly output continued to increase until 1891, when it amounted to 31,424,206 barrels.
In 1905 the twelve leading manufactures, with the value of each, were: steel and malleable iron, $363,773,577; foundry and machineshop products, consisting most largely of steam locomotives, metalworking machinery and pumping machinery, $119,650,913; pigiron, $107,455,267; leather, $69,427,852; railway cars and repairs by steam railway companies, $61,021,374; refined petroleum, $47,459,5 02; silk and silk goods, $39,333,520; tobacco, cigars and cigarettes, $39,079,122; flour and grist-mill products, $38,518,702; refined sugar and molasses, $37,182,504; worsted goods, $35,683,015; and malt liquors, $34,863,823.
But in the beginning of the 15th century new possibilities were revealed by the adaptation of the windmill to the purpose of pumping water.
In modern times pumping engines have replaced windmills, and the typical old Dutch landscape with its countless hooded heads and swinging arms has been greatly transformed by the advent of the chimney stacks of the pumping-stations.
The power of the pumping-engines is taken on the basis of 12 h.p. per moo hectares for every metre that the water has to be raised, or stated in another form, the engines must be capable of raising nearly 9 lb of water through I yd.
The methods employed have been three - (i.) the cutting of drainage channels and clearing the marshes by pumping, the method principally employed; (ii.) the system of warping, i.e.
Since 1884 the Italian Government have been systematically enclosing, pumping dry, and generally draining the marshes of the Agro Romano, that is, the tracts around Ostia; the Isola Sacra, at the mouth of the Tiber; and Maccarese.
There are pumping works and filtration beds for the water-supply of London.
Owing to the difficulty and expense of securing water from running streams by gravity systems, a great variety of methods were developed of pumping water by windmills, gasoline or hot-air engines, and steam.
Throughout the Great Plains region, east of the Rocky Mountains, and in the broad valleys to the west, windmills were extensively used, each pumping water for from 1 to 5 acres of cultivated ground.
The city is supplied with water drawn from the Missouri river above the mouth of the Kansas or Kaw (which is used as a sewer by Kansas City, Kan.); the main pumping station and settling basins being at Quindaro, several miles up the river in Kansas; whence the water is carried beneath the Kansas, through a tunnel, to a high-pressure distributing station in the west bottoms. The waterworks (direct pressure system) were acquired by the city in 1895.
This is the brine which is raised at the various pumping stations in Northwich and elsewhere around, and which serves to produce white salt.
The city is divided into twelve radial systems, each with a pumping station, and the drainage is forced through five mains to eighteen sewage farms, each of which is under careful sanitary supervision, in respect both of the persons employed thereon, and the products, mainly milk, passing thence to the city for human consumption.
The drainage-system consists of underground sewers, which are discharged by a pumping-station into a natural depression to the eastward, called the Salt Lake.
Perennial springs of large volume rarely occur in Great Britain at a sufficient height to afford supplies by gravitation; but from the limestones of Italy and many other parts of the world very considerable volumes issue far above the sea-level, and are thus available, without pumping, for the supply of distant towns.
Its full capacity has not been ascertained; it much exceeds the present pumping power, and is probably greater than that of any other single well unassisted by adits or boreholes.
Every well has its own particular level of water while steady pumping at a given rate is going on, and if that level is lowered by harder pumping, it may take months, or even years, for the water in the interstices of the rock to accommodate itself to the new conditions; but the permanent yield after such lowering will always be less than the quantity capable of being pumped shortly after the change.
When the water has been drawn down by pumping to a lower level its passage through the sandstone or chalk in the neighbourhood of the borehole is further resisted by the smaller length of borehole below the water; and there are many instances in which repeated lowering and increased pumping, both from wells and boreholes, have had the result of reducing the water available, after a few years, nearly to the original quantity.
For small supplies such a well may be perfectly successful; but however small the quantity drawn, it must obviously have the effect of diminishing the volume of fresh water, which contributes to the maintenance of the level of saturation above the sea-level; and with further pumping the fresh water would be so far drawn upon that the mean level of saturation would sink, first to a curved figure - a cone of depression - such as that represented by the new level of saturation dd, and later to the figure represented by the lines ee, in which the level of saturation has everywhere been drawn below the mean sea-level.
Pumping the acid to top of C, Glover tower.
The pumping of the acids up to the top of the towers is now always performed by means of compressed air, either in the old "acid eggs," or more economically in "pulsometers."
A law of 1909 prohibited the pumping of certain mineral waters if such pumping diminished the flow or injured the quality of the water of any spring.
In its narrow and irregular streets many of the houses are strongly bolted to keep them secure from the subsidences which result not infrequently from the pumping of brine.
In water-cooled condensers it is usual to arrange that the water passes through a large number of small pipes contained in a larger one through which the gas flows, and as it constantly happened that condenser pipes became choked by naphthalene, the so-called reversible condenser, in which the stream of gas may be altered from time to time and the walls of the pipes cleaned by pumping tar over them, is a decided advance.
