Among the exhaust fans most widely employed is the Guibal.
She turned on the exhaust fan and grabbed a chair, climbing into it to get high enough to shut the alarm off.
The tale of these glories, with their attendant woes, does not exhaust the history of the papacy.
These volumes, which called forth a multitude of answers on the Protestant side, exhaust the controversy as it was carried on in those days, and contain a lucid and uncompromising statement of Roman Catholic doctrine.
No man can exhaust by introspective analysis the hidden elements in his personality.
But this does not exhaust his significance; he was, at the same time, the renewer of the papal Maecenate in the domain of art.
The above statement does not by any means exhaust the possible predictions that can be made from the atomic theory, but it shows how to test the theory.
Speaking generally, all plants tend to exhaust particular constituents of the soil on which they grow.
The Max Kohl pumps are based on the same principle, but are constructed with more elaborate detail, leading to a greater efficiency, an exhaust of o 0008 mm.
In filtering into a vacuum the flask receiving the filtrate should be connected to the exhaust through a second flask.
Sometimes an additional vessel is employed for heating liquor by means of the exhaust steam from the engine driving the ammonia pump. Absorption machines are also made without a pump for returning the strong liquor to the generator.
In the case of factories the exhaust steam from the engines used for driving the working machinery is made use of and forms the most economical method of heating possible.
The hydraulic crane has a great advantage in possessing an almost ideal brake, for by simply throttling the exhaust from the lifting cylinder the speed of descent can be regulated within very wide limits and with perfect safety.
The exhaust steam passing from the engine through the blastpipe and the chimney produces a diminution of pressure, or partial vacuum, in the smoke-box roughly proportional to the weight of steam discharged per unit of time.
In the Webb compound the driver opened communication from the high-pressure exhaust pipe to the blast-pipe, and at the same time opened a valve giving a supply of steam from the boiler direct to the lowpressure valve chest.
But this unduly narrows the scope of Scottish philosophy, which does not exhaust itself, as is sometimes supposed, in uncritically reasserting the independent existence of matter and its immediate presence to mind.
This type of pump is, however, not very efficient, for there is not only leakage about the valves and between the piston and cylinder, but at a certain degree of exhaust the air within the vessel is insufficient to raise the inlet valve; this last defect has been met in some measure by using an extension of the piston to open and close the valve.
The invention of the barometer and Torricelli's explanation of the vacuity above the mercury column placed before the members of the Florentine academy a ready method of obtaining vacua; for to exhaust a vessel it was only necessary to join, by means of a tube provided with stopcocks, the vessel to a barometer tube, fill the compound vessel with mercury and then to invert it in a basin containing this liquid, whereupon the mercury column fell, leaving a Torricellian vacuum in the vessel, which could be removed after shutting off the stop-cocks.
A ton, and where steam is raised by coal, as in a beetroot factory, it might pay to adopt a quintuple-effect apparatus, but on a cane-sugar estate, where the steam necessary for the evaporator is raised by burning the megass as fuel, and is first used in the engines workifig the mills, the exhaust alone passing to the evaporator, there would be very little, if any, advantage in employing a quadruple effect instead of a triple effect, and practically none at all in having a quintuple-effect apparatus, for the interest and sinking fund on the extra cost would more than counterbalance the saving in fuel.
The "receiver" must be connected on the one side to the condenser, and on the other to the exhaust pump. A safety vessel and a manometer are generally interposed between the pump and receiver.
By getting rid of two, the third is proved, provided the original three exhaust the number.
The lowlands are sometimes visited by terrible sand-storms from the west, which exhaust men and kill the cotton trees.
As a statesman, he certainly committed grave faults - through excess of diplomatic subtlety, lack of forethought, and sometimes even through ingenuousness; but it must with justice be admitted that, in spite of his reputation for pugnacity and obstinacy, he never failed, either by temperament or on principle, to exhaust every peaceful expedient in settling questions.
To allow the lift-ram to descend, the pressure-water in C above the lower balance piston is discharged through the exhaust into the drain, while that above the upper piston is simply pushed back into the pressure main.
In the same way, the reflex act of coughing is useful in removing either foreign bodies or excessive secretion from the air passages; but when the mucous membrane of the respiratory tract is irritated and inflamed, it produces a feeling of tickling and a desire to cough sometimes very violently; yet the coughing simply tends to exhaust the patient, because there is really little or nothing to bring up. The same is the case in inflammation of the lung substance itself.
In phthisis also, although there may be some expectoration to bring up, yet a good deal of the irritation is in the lung substance, and the efforts of coughing are far greater and more continuous than are required for the removal of expectoration, and they simply exhaust the patient.
The pulp is heated with live steam to about 90° C., and kept at that temperature by exhaust steam in the bottom-chest.
This method is to exhaust the powdered bark with water acidulated with hydrochloric acid and then to precipitate the alkaloids by caustic soda.
Thousands of square miles in Lower Bengal annually receive a top-dressing of virgin soil from the Himalayas, - a system of natural manuring which renders elaborate tillage a waste of labour, and defies the utmost power of over-cropping to exhaust its fertility.
The difficulty about weighing in vacuo is that it is found almost impossible to exhaust the case entirely, or even to maintain a constant degree of exhaustion, by reason of the leakage connected with the weighing operations, and in consequence weighing in vacuo is not much in favour.
The methods sketched here do not yet exhaust the armoury of the analytical chemist, but it can only be pointed out in passing that the detection of hydroxylated acids enables the analyst to ascertain the presence of castor oil, just as the isolation and determination of oxidized fatty acids enables him to differentiate blown oils from other oils.
Damper G, which may be raised or lowered by a chain reaching to the ground, and serves for regulating the speed of the exhaust gases, and thereby the draught of air through the fire.
