 ... the suit was stiff, and the air pressure gave further resistance that had to be overcome. Rip let most of the air out of the suit, then fought for breath until the pain in his arm told him that Koa had succeeded. He inflated the suit again and thanked the sergeant ...

... years used the locomotive form of boiler for his steam launches, working them under an air pressure—produced by a fan discharging into a close stokehold—of from 1 in. to 6 in. of water, as may be required. The experiments made gave an evaporation of 7.61 lb. of water from 1 lb. of coal at 212 Fahr., with 2 in. of water pressure, and 6.41 lb. with 6 in. of pressure. These results are low, but ...

... the air is compressed. To get economical results it is, of course, necessary to cut off in the steam cylinder, so that at the end of the stroke, when the steam pressure is low, as indicated by the dotted line (Fig. 5), the air pressure is high, as similarly indicated. The early direct-acting compressor used steam at full pressure throughout the stroke. The Westinghouse pump, applied to locomotives, is built on this principle, and those who have observed it work have ...

... test of home conditions prejudicial to health that will register the fact as a thermometer tells us the temperature, or as a barometer shows moisture and air pressure? The house address alone is not enough, for many children surrounded by wealth are denied health rights, such as the right to play, to breathe pure air, to eat wholesome food, to live sanely. Scholarship will not help, because the frailest child ...

... bell, immersed in a tank of water, with telephone receivers attached by which one could "listen in," for example, before rising, say, from sixty feet to twenty feet, and thus "hear" the hulls of other ships. The bell was struck by means of air pressure, and was the same as that used for submarine signalling on ships. Water, being dense, is an excellent conductor of sound. Even in the submarine itself, I could hear the muffled clang ...

... control-man was tugging at a lever, his muscles bulging on arms and back, his face white-drawn and tense. "Look!" he grunted, and jerked a grim jaw at one of the dials. The long needle was moving rapidly to the right. "I can't hold the air pressure!" ...

... heard a terrific roar and crash, and with the noise of a thunderbolt a 15 in. shell exploded beneath the bridge. The blast of air swept away everything that was not firmly riveted down, and the chart-house disappeared bodily. But the astounding thing was that this same air pressure closed the door of the conning-tower! The Englishman was polite; having first opened the door, he carefully shut it again for us. I searched with my glass for the enemy, but, although the salvos were still falling about us, we could see practically nothing of him; all that was really visible were ...
