"Air pump" Quotes from Famous Books
 ... quick-lime and white of eggs: When the lute was perfectly dry, the weight of the whole apparatus was determined to within a grain, or a grain and a half. I next exhausted the baloon, by means of an air pump applied to the tube XXX, and then introduced oxygen gas by means of the tube yyy, having a stop cock adapted to it. This kind of experiment is most readily and most exactly performed by means of the hydro-pneumatic machine described by Mr Meusnier and me in ...

... operator stands so near to his work; but as they carry a comparatively small quantity of liquid and do not throw it rapidly, they are expensive when much work is to be done. Yet, in ordinary home grounds, the knapsack pump or compressed-air pump is one of the most efficient and practicable ...

... respect to the remedies, these are as simple as the evils to be cured are great. For instance, there was a lodging house in Glasgow where fever resided; "but by making an opening from the top of each room, through a channel of communication to an air pump, common to all the channels, the disease disappeared altogether." Other modes of ventilation are suggested in the Report; and one very simple device introduced by Mr. Toynbee, a perforated zinc plate fixed in ...

In the former they studied practical chemistry, and in the latter they studied practical mechanics, making for themselves an air pump and an electrifying machine, as well as preparing the various models used in the course of the lectures.

... perfectly air-tight, and strong enough, by means of iron bars running alternately inside and out, to resist the pressure of the atmosphere, when the machine should be exhausted of its air, as we took the precaution to prove by the aid of an air pump. On the top of the copper chest and on the outside, we had as much of the lunar metal (which I shall henceforth call lunarium) as we found by calculation and experiment, would overcome the weight of the machine, as well as its contents, and take us to the moon on the third ...
