"Low-pressure" Quotes from Famous Books
 ... wire-bottomed tray is a perforated cross-pipe that is connected with a compressed-air line. This is used when case-hardening for colors. The shop that has no air compressor may rig up a satisfactory equivalent in the shape of a low-pressure hand-operated air pump and a receiver tank, for it is not necessary to use high-pressure air for this purpose. When colors are desired on case-hardened work, the treatment in quenching is exactly the same as that previously described except that air is pumped through this pipe and keeps the ...

... were established at the Weehawken Shaft and at the Manhattan Shaft, including at each, low-pressure air compressors of a capacity of 13,000 cu. ft. of free air per minute and also high-pressure air compressors for drills, hydraulic pumps, ...

... triple-expansion marine engine. Steam enters the high-pressure cylinder[4] at, say, 200 lbs. per square inch. It exhausts at 75 lbs. into the large pipe 2, and passes to the intermediate cylinder, whence it is exhausted at 25 lbs. or so through pipe 3 to the low-pressure cylinder. Finally, it is ejected at about 8 lbs. per square inch to the condenser, and is suddenly converted into water; an act which produces a vacuum, and diminishes the back-pressure of the exhaust from cylinder C. In fact, the condenser exerts a sucking power ...

... the creator of low-pressure and high-pressure, the inspirer of the "ticker," is the great generator of business. Here I found Henderson in the morning hour, and he came up to me on the call of a messenger. He approached, nonchalant and smiling as usual. "Do you see that man," he said, as we stood a moment ...

... order, it was arranged, by means of separate pipes, that any of the cylinders could be cut off, and thus the other two, or, at a pinch, even one alone, could be used. In this way the engine, by the mere turning of a cock or two, could be changed at will into a compound high-pressure or low-pressure engine. Although nothing ever went wrong with any of the cylinders, this arrangement was frequently used with advantage. By using the engine as a compound one, we could, for instance, give the Fram greater speed for ...
