Helium alone refuses to be absorbed, and it can be pumped off from the charcoal in a state of absolute purity.
The irritation is caused by the rostrum of the insect being inserted into the skin, from which the blood is rapidly pumped up. A third human louse, known as the crab-louse (Phthirius pubis) is found amongst the hairs on other parts of the body, particularly those of the pubic region, but probably never on the head.
As his words soaked in, blood pumped in her temples.
The system is hermetically sealed after being pumped full of water, an expansion chamber in the shape of a pipe of larger dimensions being provided at the top of the system above the highest point of circulation.

The tools are then withdrawn, the well is sand-pumped, and preparations are made for the next ' run.'
Scavengers were employed in early times, and sewage was received into wells and pumped into the kennels of the streets.
The juice is then drawn off and pumped up to one of the double-bottomed defecators and redefecated, or, where juice-heaters have been used instead of defecators, the scums from the separators or subsiders are heated and forced through filter presses, the juice expressed going to the evaporators and the scum cakes formed in the filter presses to the fields as manure.
Hence, when in 1850 a hydraulic installation was required for a new ferry station at New Holland, on the Humber estuary, the absence of water mains of any kind, coupled with the prohibitive cost of a special reservoir owing to the character of the soil, impelled him to invent a fresh piece of apparatus, the "accumulator," which consists of a large cylinder containing a piston that can be loaded to give any desired pressure, the water being pumped in below it by a steam-engine or other prime mover.
A hawk made a wide swing across the grassland and then suddenly dived, jerking up at the last second, its great wings straining as it pumped back into the air with added weight.
Katie laughed shortly as she whirled the motor over and pumped the accelerator.
He pumped his arms hard, ignoring the cries of three men as they fell into pits or were snapped up by traps with iron teeth.
It is seen that the action is intermittent, liquid only being discharged during a down stroke, but since the driving force is that which is supplied to the piston rod, the lift is only con ditioned by the power available and by the strength of the pump. A continuous supply can be obtained by leading the delivery pipe into the base of an air chamber H, which is fitted with a discharge pipe J of such a diameter that the liquid cannot escape from it as fast as it is pumped in during a down stroke.
To secure this marvellous return, with an annual rainfall of 26 in., as much as 52,000,000 gallons of water are pumped per 24 hours from artesian wells on one estate alone.
After filtration the water is pumped to the storage tanks.
The head of the insect contains a muscular pharynx by means of which the blood from the wound inflicted by the proboscis (labium) is pumped into the alimentary canal and the so-called sucking-stomach.
To find the total heat of a substance in any given state defined by the values of p and 0, starting from any convenient zero of temperature, it is sufficient to measure the total heat required to raise the substance to the final temperature under a constant pressure equal to p. For instance, in the boiler of a steam engine the feed water is pumped into the boiler against the final pressure of the steam, and is heated under this constant pressure up to the temperature of the steam.
The water necessary to the process is pumped from the river; as much as 2000 gallons per minute is used on the larger dredges.
Deep, is divided into two compartments, each capable of containing a full-sized battleship, and can be pumped dry in eight hours by two 600 h.p. steam pumps.
The piston was in communication with a vacuum vessel from which the air had been pumped by steam power.
The oil is pumped from buried tanks and warmed to about 90° F.
At Olean it is pumped into pipes which extend as far north as Buffalo and as far east as Long Island City.
Petroleum has been found in the Ficksburg, Ladybrand and Harrismith districts, and is pumped to a limited extent.
These piles have a flat flange at the bottom, and water is pumped in at the top of the pile, which is weighted to prevent it from rising.
Sand is thus blown or pumped from below the piles, which are thus easily lowered in ground which baffles all attempts to drive in piles by blows.
Long, constructed in 1888, water is pumped by means of one of the largest single pumps in the world from the lake into the upper Milwaukee river, which is thus completely flushed by fresh water every twenty-four hours.
The Washburn project was to irrigate 5000 acres in McLean county with water pumped from the Missouri river.
In depth, and when 25 barrels were pumped from it in a day its production was considered enormous.
The water may be drainage-water from lands at a higher level; or it may be water from a neighbouring river; or it may be drainagewater accumulated from a farm and pumped up to the necessary level.
It is not enough that it should be pumped on to the land at the expense of the landowner.
In Cheshire the surface-water trickling through the overlying strata dissolves the salt, which is subsequently pumped as brine, but at Middlesbrough the great depth and impermeability of the strata precludes this, so another method has been resorted to.
In the former case it is often difficult to obtain the brine at a density even approaching saturation, and chambers and galleries are sometimes excavated within the saliferous beds to increase the dissolving surface, and water let down fresh is pumped up as brine.
The purer rock-salt is often simply ground for use, as at Wieliczka and elsewhere, but it is more frequently pumped as brine, produced either by artificial solution as at Middlesbrough and other places, or by natural means, as in Cheshire and Worcestershire.
When it has completely cleared, the liquid caustic is ladled or pumped out into sheet-iron drums, holding about 6 cwt.
It has been found, however, that very efficient condensers can be made with compressed air as dielectric. If a number of metal plates separated by small distance pieces are enclosed in an iron box which is pumped full of air to a pressure, say, of 10o lb.
The water-supply system is owned and operated by the borough; the water is derived from streams flowing southward in the sparsely settled area east of the borough, and also from driven wells in the same region; it is pumped by ten engines at Ridgewood to a reservoir having a capacity of about 300,000,000 gallons, while a part of it is re-pumped to a high service reservoir near the north entrance to Prospect Park for the service of the most elevated part of the borough.

Below the surface is tapped and pumped by electricity generated from the only surface water of the region, Camas Creek.
The brine is pumped into conduits, carried to large ponds and there evaporated by the sun; during late years the salt has been refined here, being purified of the sulphates and magnesium compounds which formerly rendered it efflorescent and of a low commercial grade.
The water-supply of Pittsburg is taken from the Allegheny river and pumped into reservoirs, the highest of which, in Highland Park, is 367 ft.
To remove this obstruction the water was pumped out while the plugs kept the orifices closed.
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.
Pumps, however, may be (and have been) placed deep down in boreholes, so that water may be pumped from much greater depths.
The general lesson to be learned from these facts is, that if the purity of the water of any well not far removed from the sea is to be maintained, that water must not be pumped down much below the sea-level.
Most of the liquor arriving at the bottom, after mechanically separating the tar, is pumped back into s, but a portion is always withdrawn and worked for ammonium sulphate.
The hot water from B, freed from tar, is pumped into a third tower C, through which cold air is forced by means of a Root's blower by the pipe w.
