Ignition is by two high-tension magnetos, and a compressed air self-starting arrangement is provided. Two oil pumps are fitted for lubricating purposes, one of which forces oil to the crankshaft and connecting-rod bearings, while the second forces oil to the valve gear, the cylinders being so arranged that the oil which flows along the walls cannot flood the lower cylinders.

The valve is composed of two portions, a cup and a lip. The time occupied from first removing the valve from the float, until the inflation, and the expulsion of air into the float being completed, so that the valve begins to move again, is 61 seconds, from the mean of several experiments.

The spaceman shrugged. The doings of Planeteers were no concern of his. His shrug said so. Rip realized there was no use talking further. He ran down the long corridor toward the outer edge of the platform. The enlisted men’s squadrooms were near Valve Ten. So was the supply department. His gear had departed on the Terra rocket, and he couldn’t go to space with only the tunic on his back.

They do no harm, and are a safety valve which should be understood. Honest sympathy, where sympathy is merited, will give weight to warning and disapproval, which would have no weight at all if the whole fabric of the imagination, which is so real and so precious to the imaginer, were condemned without discrimination.

What makes the street so interesting is that you can look in and see everything going on. I forgot to mention the most interesting street thing I've seen, a bird catcher with a long limed pole like a bamboo fishing rod, a basket with a valve door to put them in and some other utensils. I didn't see him catch any, though. Sunday Morning, March 2.

The heat has expanded their gas and they fear that the bag of the ship may explode at any moment. They cut off suddenly. The accident may have occurred already." "Why don't they open the valve?" "I suppose because in that case they'd stand every chance of dropping into the sea," responded Frank, disconnecting the instrument and removing the head-piece.

Then the professor gave three or four turns to a wheel which controlled the valve admitting vapour to the engine, throwing the valve wide open, whereupon the humming sound suddenly rose to a loud and rather high, but pleasing, note as the huge propeller whirled round at its full speed of one thousand revolutions per minute.

He inspected the needle valve with much care, and had Foster on the front seat trying to start her afterwards. He looked for short circuit. He changed the carburetor adjustment, and Foster got a weary chug-chug that ceased almost as soon as it had begun. He looked all the spark plugs over, he went after the vacuum feed and found that working perfectly.

"I suppose so," said Mrs. Bates, slowly. She crossed over to the radiator and began working at the valve. "I told Granger I knew he'd be sorry if he didn't put in furnace-flues too. I really can't ask you to take your things off down here; let's go upstairs that's the only warm place I can think of." She paused in the hall. "Wouldn't you like to see the rest of the rooms before you go up?"

The steam after passing through the valve, which, in the case of small turbines, is hand-operated, goes in turn through the automatic stop-valve B, the function of which is to automatically shut steam off should the turbine attain a predetermined speed above the normal, the steam strainer C, and finally through the governing valve D into the turbine.
