Before the gas passes from the condensers into the purifiers, it passes through a kind of pump, termed an exhauster, driven by steam power.
Condensers are either air-cooled or water-cooled, or both.
Three huge dynamo-motor arrangements took up the room's far end, and from them a tangle of wiring led through square black condensers and transformers to a battery of great tubes.

We shall not thus be inhaling the noxious gases, nor be exposed to the attacks of mosquitoes and other germ-bearing insects; whilst river-water passed through our condensers will be perfectly drinkable.

These condensers must not be allowed to get wet or their efficiency will be impaired.
S is a hard rubber plate, provided with a revolving metal arm and handle, H, and four contact points, P, which latter receive the ends of the wires from the groups of burner condensers B by means of nuts or binding posts.

Condensers are just the other way in their action.
If the wires are transmitting high-frequency currents these condensers offer tiny waiting-rooms where the electrons can run in and out without having to go on to the grid of the next tube.
To these condensers we connect inductances and these inductances we couple to our transmitter and receiver as shown in Fig.
What we really have, is a lot of tiny condensers which I have shown in the figure by the light dotted-lines.
And so it has, but we usually call it "impedance" instead of resistance because straight wires resist but coils or condensers impede alternating e.
What was really important was the sort of condensers made possible by a genuinely good dielectric material.
Can't make very good condensers out of this," he objected.
As arc lamps when tilted upward break condensers very rapidly, the light is usually reflected upward by means of mirrors set as indicated in Figure 197.
For the purpose of projection we can use only the light which strikes the condensers direct from the arc.
The best methods of preventing heating are: a large lamp house well ventilated and condensers of such focal length as to allow the arc to be maintained at some distance from them.
The focal length of the condensers determines the point at which the arc must be maintained.
The flatter the condensers are, the farther away the arc may be, and the less will be the heating; but this position is accompanied with considerable loss of light.
But if the light is brought too close, there will be undue heating of the condensers and these, especially the one nearest the light, will be likely to break.
The average current in the arc should not exceed 30 amperes and it will be found that excellent pictures can be obtained with 25 amperes or even less and the cost of energy, carbons, and condensers will be less.
The face occupies the space marked by a half circle and two arc lamps with condensers are trained upon it at very close range.
In order to obtain the most light with the least expenditure of current and heat in the lamp house, the crater must be formed in such a manner as to face the center of the condensers as nearly as possible.
The position of the arc with reference to the condensers is also an important point to consider.
A method of projection sometimes resorted to when condensers are broken.
Rays reflected by the lamp house do not pass through the condensers in the same direction as those coming directly from the crater and will not focus with them.
The condensers are provided for the purpose of gathering and condensing as many of the scattering light rays of the arc lamp as possible and bringing them to bear upon the slide and the objective.
Varley, who first applied condensers to sharpen the signals, and Professor Fleeming Jenkin, of Edinburgh University.
The condensers are merely used to sharpen the action of the current, and render the signals more concise and distinct on long cables.
These tubular condensers are particularly good as they may be easily cleaned.

From the distilling column K the phlegm or raw spirit passes to the phlegm tank L from which it is drawn as desired into the rectifying column M, thence into the coolers and condensers and thence into the alcohol tanks N.
Where two or more condensers can be coupled together by means of plugs, switches or other devices.
It consists of a coil of wire wound on a soft iron core and has a large inductance, hence the capacitance of the filter condensers are proportionately smaller than where a small inductance is used which has been the general practice.
It is largely used in makingcondensers both for transmitting and receiving sets.
