"Valve" Quotes from Famous Books



... shook the west coast of South America for more than 2,500 miles, by which many thousands of the inhabitants perished, and many more were rendered homeless. Slight shocks were felt in many parts of Europe, and even in England. Vesuvius was our safety-valve. The pressure must have been very great which opened two new craters in the Atrio del Cavallo and forced out such a mass of matter. There is no evidence that water had been concerned in the late eruption of ...

... Miller slapped the regulator between the guide rods. As the three young men again threw themselves upon the chain and forced the regulator into place, the crucial moment had arrived. The controlling valve of the regulator was open, of course, and as the rushing gas was again concentrated into one stream, a new fiery jet shot upward. But the lateral streams had been controlled and again Ewen applied the wrench to thread ...

The Easterns do not understand a jest, especially in a harem; and not being addicted to irony (that great safety-valve for enthusiasm), they pass rapidly from immovability to very significant and sometimes disagreeable action.

That is to say, while the furnace-door, the gauges, and the safety-valve were inside, the main portion of the boiler was outside the walls.

The steam-valve is a packed slide with but little lap, and the expansion-valve is an adjustable slide working on the back of the steam-valve. The boilers are of the vertical water-tube type, with the tubes above the furnaces, and are supplied ...

... close to leeward. He waved the lantern, but the lighter, with sea and current on her weather bow, forged almost straight ahead, and the straining hawser dragged the launch back. Reaching forward, Dick opened the throttle valve to its limit, and then sat grim and still while the throb of the screw shook the trembling hull. Something would happen in the next half minute unless he could get the lighter round. Glancing back, he saw her ...

The governor is no good; and, though Grummet or Links have their grip on the throttle valve all the while to check the steam, and I've every stoker and oiler on duty, the bearings are getting that heated that I'm afraid of the shaft breaking at any moment.

... distress which he had experienced was so great and his deliverance so simple and comprehensible to his soul, that the power of the idol had melted before it. The siren continued to howl. The strikers had fastened the valve with a rope, locked the furnace room and thrown the keys in through the window, so they could not be reproached with having them. After an hour the fire department silenced its voice. In the meantime a stream of workingmen was ...

I doubt whether we shall ever understand some of them without using the very letter of Fechner's conception of a great reservoir in which the memories of earth's inhabitants are pooled and preserved, and from which, when the threshold lowers or the valve opens, information ordinarily shut out leaks into the mind of exceptional individuals among us. But those regions of inquiry are perhaps too spook-haunted to interest an academic audience, and the only evidence I feel it now decorous to bring to the support of Fechner is ...

Mr. Adams had the faculty of forcible expression when he chose to employ it, as may be seen from a few specimen sentences.

A cut across an animal of this class will show us better the bilateral arrangement of the parts. In such a section we see the edge of the two shells on either side; within ...

A tank under the seat held three gallons of gasoline which was fed to the motor through a small pipe and a mixing valve. The ignition was by electric spark. The original machine was air-cooled—or to be more accurate, the motor simply was not cooled at all. I found that on a run of an hour or more the motor heated up, and so I very shortly put a water jacket around the cylinders and piped it ...
