They learned that the big lights were a new type of tungsten lamp filled with nitrogen gas which made them burn three times as bright as other lamps. They discovered that the original photographs were only three-quarters of an inch long and they were magnified from thirty to fifty thousand times when they were projected onto a movie screen by the machine in the theater.
"And then oh, it's all mixed up, but Blount couldn't find any gold and so he leased the mine to Wiley. And the minute he found that the white quartz was tungsten, and worth three dollars a pound, he was mad as anything and did everything he could to keep him from meeting the payment. But Wiley went ahead and shipped a lot of ore and made a lot of money in spite of him.
While Ned was pressing the button, and hastily telling the giant what had happened, urging him to get in pursuit of the intruder, Tom had taken from his bureau a powerful, portable, electric flash lamp, of the same variety as that used by the would-be thief. Only Tom's was provided with a tungsten filament, which gave a glaring white pencil of light, increased by reflectors.
In that short time he must meet heavy obligations, pay off his notes, buy Blount's stock and purchase the mine; and if anything should happen if the hoist should break down, the mill blow up, the market for tungsten fail well, he could kiss the Paymaster good-by. The market and other influences were on the knees of the gods, but Wiley decided that there should be no more accidents.
The big help is, that the tungsten-beryllium will throw off the energy pretty fast, and in a big ship, with a whale of a lot of matter to heat, the Strangers will simply give up the idea." "Yes, but only two ships in the system compare with them in size." "Sorry but I didn't build the IP fleet, and there are lots of tungsten and beryllium on Earth. Enough anyway."
None other than the lieutenant himself had lately passed in the corridor. How, then, had this electric light bulb been shattered and made to give forth the sound of the explosion? "It wouldn't go up with a noise like that," murmured the lieutenant to himself. "These tungsten lights don't explode like that, except when rapped in some way. They don't blow up, when left alone.
Frank Nelsen meant the journey to be vagabond escape, an interlude of to hell with it relief from the grind, and from the increasingly uncertain mainstream of the things he knew best. He rode with a long train of bubbs and great sheaves of smelted metal rods tungsten, osmium, uranium 238. The sheaves had their own propelling ionic motors. He lazed like a tramp.
The tungsten lamps first made were very delicate, and it was not until W. D. Coolidge, in the research laboratories of the General Electric Company at Schenectady, invented a process for producing ductile tungsten that they became available for general use. The dynamo and the central power station brought the electric motor into action. The dynamo and the motor do precisely opposite things.
Chloride tungsten or titanium passed through hot tube, depositing a film of metal on the carbon; or filaments of zirconia oxide, or alumina or magnesia, thoria or other infusible oxides mixed or separate, and obtained by moistening and squirting through a die, are thus coated with above metals and used for incandescent lamps.
He shoved down the little sliding catch, but there was no glow in the tiny tungsten bulb. "You have me at your mercy if you wish to sell me a lamp," he went on, with a smile and a shrug of his shoulders, not unlike that of Lieutenant Secor. "Hasn't your friend a spare light?" asked Joe quickly. "My friend?" repeated the German, as though surprised. "You mean ?" "I mean Lieutenant Secor."
