I'm pretty sure these jets aren't here for anyone else.
The use of small auxiliary blowing ventilators underground, for carrying air into workings away from the main circuits, which was largely advocated at one time, has lost its popularity, but a useful substitute has been found in the induced draught produced by jets of compressed air or high-pressure water blowing into ejectors.
We thought she drew the jets here.
These elaborate waterworks were, according to Dorpfeld, constructed by the Peisistratids in order to increase the supply from the ancient spring Callirrhoe; the fountain was furnished with nine jets and henceforth known as Enneacrunus.
The methods by which such results are to be obtained cannot, however, as yet be practised economically on a working scale; one great difficulty in applying them to the refining of metals is that the jets of liquid would be liable to carry with them articles of anode mud, and Swan has shown that the presence of solid particles in the electrolyte is one of the most fruitful causes of the well-known nodular growths on electrodeposited copper.
Liz plopped a straw hat with a red, white, and blue band on Dean's head just as three jets in close formation screamed overhead, buzzing the town in a deafening roar.
The jets came from the west, beyond the river, a realization that didn't register until the ground shook under the impact of the first laser missile strike dropped.
At the first drop of laser missiles, Brady had figured there was one thing that would make the fed jets target the inconsequential town, and it was Lana.
He touched his net implant but found the network scrambled, indicating the jets were sending out electromagnetic pulses in addition to the missile strikes.
If all the connexions are sound, the copper oxide is gradually heated from the end a, the gas-jets under the spiral d are lighted, and a slow current of oxygen is passed through the tube.
Mine fires may originate from ordinary causes, but in addition they may result from the explosion of fire-damp or from the accidental lighting of jets of fire-damp issuing from the coal.
This conclusion, however, is absolutely irreconcilable with the known fact that jets of water rise nearly to the same height as their reservoirs, and Newton seems to have been aware of this objection.
0-00, u = b at the branch point B, u = j, j at the end of the two diverging streams where = -oo; while ¢=0 along the stream line which divides at B and passes through A, A'; and 4 ' =m, -m' along the outside boundaries, so that m/Q, m'/Q is the final breadth of the jets, and (m+m')/Q is the initial breadth, c, of the impinging stream.
The motion of a jet impinging on an infinite barrier is obtained by putting j = a, j' = a'; duplicated on the other side of the barrier, the motion reversed will represent the direct collision of two jets of unequal breadth and equal velocity.
Outside the town is the Fontana delle novantanove cannelle, a fountain with ninety-nine jets distributed along three walls, constructed in 1272.
Bleeding from an artery is of a bright red colour, and escapes from the end of the vessel nearest the heart in jets synchronous with the heart's beat.
Disintegrating auriferous gravels by powerful jets of water, and the sluice system described above; in the second case the vein stuff is prepared by crushing and the amalgamation is carried out in mills.
In France, single jets made of glass were first employed, and then P. Resener, H.
In one instance the quantity of water required to keep down the dust in a mine raising 850 tons of coal in a single shift was 28.8 tons, apart from that required by the jets and motors.
Billwiller introduced the idea of sucking air into the flame at or just below the burner tip, and at this juncture the Naphey or Dolan burner was introduced in America, the principle employed being to use two small and widely separated jets instead of the two openings of the union jet burner, and to make each a minute bunsen, the acetylene dragging in from the base of the nipple enough air to surround and protect it while burning from contact with the steatite.
Barrett further showed by using smoke jets that the flame is not essential.
§ 7 seq.) describes a number of beautiful experiments with jets at higher pressure than ordinary, say to in.
An excellent account of these and other jets is given in C. V.
It oxidizes the carbon also, which escapes in purple jets of burning carbonic oxide.
A jet or jets of water impinge on the cups, the interiors of which are shaped in such a way that the jet is discharged parallel to its original direction.
By introducing perforated shields of ebonite between the electrodes, so that the full current-density was only attained at the centres of the jets, these ill effects could be prevented.
The application of these results to actual jets presents no great difficulty.
In this case drops which break away with different velocities are carried under the action of gravity into different paths; and thus under ordinary circumstances a jet is apparently resolved into a " sheaf," or bundle of jets all lying in one vertical plane.
In another form of the experiment, which, though perhaps less striking to the eye, lends itself better to investigation, the collision takes place between two still unresolved jets issuing horizontally from glass nozzles in communication with reservoirs containing water.
In the absence of dust and greasy contamination, the obliquely colliding jets may rebound from one another without coalescence for a considerable time.
In external diameter, heated by over 7000 gas jets arranged in rows.
In this condition there is complete electrical insulation between the jets, as may be proved by the inclusion in the circuit of a delicate galvanometer, and a low electro-motive force.
But if the difference of potential exceed a small amount (i or 2 volts), the jets instantaneously coalesce.
The transverse vibrations of non-circular jets allow us to solve a problem which at first sight would appear to be of great difficulty.
When two or more jets were used side by side the deposit was good opposite the centre of each, but bad at the point where two currents met, because the rate of flow was reduced.
Ragot and others made burners in which two jets of acetylene, coming from two tubes placed some little distance apart, impinged and splayed each other out into a butterfly flame.
The water is brought from a ditch on the high ground, and through a line of pipes to the distributing box, whence the branch pipes supplying the jets diverge.
The magnetometric method was employed, and the metals, in the form of ovoids, were heated by a specially designed burner, fed with gas and air under pressure, which directed 90 fine jets of flame upon the asbestos covering the ovoid.
