It suffices to cause the current of water which issues from the condenser of the frigorific machine to pass into the worm of the boiler.
The surface condenser remains as it was ten years ago, with scarcely a detail altered.
I scaled one ladder and fastened a condenser over the boss; descended; sent Larry up to watch it, and, ascending the second ladder, rapidly fixed the other in its place.
The shunt consists of a wire leading from the copper to the carbon rod with a condenser and an inductance coil inserted in it.
Current from a dynamo flows through the arc, whereupon currents oscillate through the condenser and coil (as described in the text).
Lastly, when the earth forms a part of the condenser the waves cling to it, so that instead of being largely dissipated into space, they move along the surface of the earth.
Carbonic acid gas liquefies at a very moderate temperature and pressure, and so while it leaves the compressor as a gas it becomes liquid in the condenser and remains so until it has passed the regulating valve.
The condenser is thus formed by the earth as one plate, the elevated wires as the other, and the intervening air as the insulator.
Passing then through the bottom of the tank the gas travels from right to left through the "regulating valve" and into an arrangement almost exactly similar to the condenser but called the evaporator.
In front of it was the very searchlight, with its curious condenser that I had seen in the cavern.
Had it not been for this condenser I should have taken the whole thing to be an elaborate searchlight.
In cases where the condenser is likely to become plugged there is a pipe by means of which live steam can be injected into the condenser.
Sometimes an "adapter" is used; this is simply a tapering tube, the side tube being corked into the wider end, and the condenser on to the narrower end.
The supply of water to the condenser is regulated according to the volatility of the condensate.
In modern times the laboratory practice of distillation was greatly facilitated by the introduction of the condensernamed after Justus von Liebig; A.
The condenser consists of a vertical cylinder having manifolds at the head and foot and through which a number of tubes pass.
This vessel has two tubulures: through one the end of the condenser projects so as to be over one of the receiving tubes; the other leads to the pump.
For less volatile liquids the Liebig condenser is most frequently used.
The object of the condenseris to collect as much light as possible from the source, and pass it through the object in a uniform beam.
Since effective single lenses of large diameter are necessarily of long focus, a really good condenser of considerable diameter and yet of short focus must be a combination of two or more lenses.
In some lanterns this is guarded against by placing a plate of thin glass between the condenser and the light.
A good compound condenser for ordinary work is that proposed by Herschel, consisting of a biconvex lens and a meniscus mounted together with the concave side of the meniscus next the light.
For this purpose the condenser should subtend as large an angle as possible at the source of light.
It is essential that the condenser be white and limpid and free from defects or striae.

The evaporative condenser simply consists of a series of pipes, in which is the steam to be condensed, and over which the water is allowed to fall in a continuous rain.
By this arrangement there is evaporated from the outside of the condenser a weight of water which goes away in a cloud of vapor, and is nearly equal to that which is condensed, and is returned as feed into the boiler.
The tuning coil and the condenser are used to give the waves whatever length the government says they must have.
The tuning coil and condenser enable the operator to tune his receiving apparatus to the length of wave which the transmitting station is sending out, and this operation is called tuning in.
The bottom frame, on which also the condenser is cast, forms the base of the engine: on one end of it the cylinder is set; on the other end are the guides for the cross head, and in the middle are the bearings for the crank shaft.
The passage communicating between the condenser and the top of the balance piston was too small, and the pins at the ends of the link connecting the valve and balance piston were formed with an inadequate amount of bearing surface.
The jet entered the condenser instead of the cylinder as was the previous practice, and this method is now the one in common use.
But what becomes of the cold water which is let into the condenser to condense the steam?
From the bottom of the condenser a short pipe leads to the air pump J, and in this pipe there is a flap valve, called the foot valve, opening towards the air pump.
The injection water is generally admitted to the condenser by means of a slide valve, but a cock appears to be preferable, as it is more easily opened, and has not any disposition to shut of its own accord.
It may be assumed as a determination sufficiently exact, that 10 square feet of surface of the condenser can cool a cubic foot of gas per minute to the temperature of the cooling water.
From the other side of the vertical branch f, the main pipe proceeds to the condenser D, and thence by the pipe l, into the purifier E; from which the gas is immediately transmitted by the pipe p into the gasometer F.
Through the tube k, cold water flows into the condenser chest, and the warm water passes away by a pipe at its upper edge.
The air blast, moreover, by being diffused round the glass of the condenser apparatus, would somewhat mask the appearances.
In this circulation it also begins to act as a refrigerating medium, taking up a portion of heat from the vapours that pass through the pipe B, and afterwards it acts as a further condenser in the cylinder, in the way described.
The small air-tight condenser F, connected with the efflux pipe f of the refrigerator, is furnished below with a discharge cock g, and surrounded by a cooling case, for the collection of the water condensed by the refrigerator.
For this purpose, the cock f must first be shut, the cold water is to be then run out of the condenser G, and k and g are to be opened.
A tube introduces the gas from the condenser into the first vessel, another tube does the same thing for the second vessel, &c.

Condenser breakage is quite an important subject and one upon which there is much argument among operators.
If a spot lamp is turned upward, the heat of the arc rising will be great enough to make condenser breakage a very serious problem.
There is no very accurate relation necessary between the focal length of condenser and objective.
This can be done by stretching a string from the lamp house, through the center of the condenser opening, film gate, and objective lenses.
It is advisable, during the heating, to shake the flask occasionally; some material sublimes into the condenser and must be pushed down with a glass rod.
It is, therefore, necessary that the stream passing through the condenser should be sufficiently rapid to cause it to form a uniform film over the receiving flask.
This mixture is stirred on the steam bath under a reflux condenser for one to two hours, allowed to cool slowly, and then chilled in an ice bath and filtered.

The flask is then fitted with a fractionating column, I meter long, to which is attached a condenser and an automatic separator so arranged that the lighter liquid flows off to a receiver (Fig.
The mixture is then heated with a reflux condenser on the steam bath for four hours, cooled and filtered with suction to remove most of the sodium chloride.
The reflux condenser is now removed and one set for downward distillation is attached to the side-arm.
The phenylacetic acid may also be made by boiling under a reflux condenser for eight to fifteen hours, without a stirrer, but this method is not nearly so satisfactory as that described in the procedure.

The secondary of the induction coil, in series with the receiver, is connected also across the line in series with a condenser and the transmitter.
When the electromotive force reaches its maximum, the condenser will have received its full charge for that potential, and the current flow into it will cease.
The condenser in this case prevents the drop being short-circuited with respect to ringing currents and yet permits the voice currents to flow readily through it.
These condensermethods of telephony have not become commercial.
The two windings are bridged across the cord circuit, with a 1/2-microfarad condenser in series in the tip strand between the two winding connections.
As is well known, a 1/2-microfarad condenser not only transmits voice currents with ease but also offers a very high apparent resistance to ringing currents.
The steady current from the central-office battery finds ready path through the transmitter and the impedance coil, but is prevented from passing through the receiver by the barrier set up by the condenser 8.
Other companies mount only the transmitter, receiver, and hook switch on the desk stand proper and put the condenser or induction coil, or other device associated with the talking circuit, in the bell box.
