But when the laying of the latter is practicable as it will be in the majority of instances the gas for an engine will be obtainable without the need for forcing lime to combine with carbon as in calcium carbide. Petroleum oil is estimated to supply power at just one-third the price of acetylene gas made with calcium carbide at a price of £20 per ton.
"I 've gone through!" he announced in happy surprise. "I 've gone through. We 're at the end of it!" Up went Fairchild's carbide. Where the pick still hung in the rocky mass, a tiny hole showed, darker than the surrounding refuse. He put forth a hand and clawed at the earth about the tool; it gave way beneath his touch, and there was only vacancy beyond.
This calculation was drawn up before the occurrence of the material rise in the price of "petrol" in the last year of the nineteenth century; while, concurrently, the price of calcium carbide was falling.
"North American Carbide & Metals," said Thorn quietly, "is not a member of any patent pool, Mr. Sorensen." "I know," Sorensen said agreeably. "Battery patents are trickier than automotive machinery patents. That's why I'm doing this my way. I'm not selling the gadget as such. I'm selling results.
The electric furnace is just as readily applicable for forcing the combination of an intractable element, such as nitrogen, with other materials suitable for forming a manurial base, as it is for making calcium carbide by bringing about the union of two such unsociable constituents as lime and carbon.
Thus when calcium carbide is heated and brought into contact with nitrogen one atom of carbon is given up and two atoms of nitrogen take its place, resulting in the production of cyanamide. Other important electro-chemical processes are involved in the electrolysis of the various alkaline salts to obtain metallic sodium and such products as chlorates.
"It's important that it should be the cheapest possible," went on Clark, apparently without hearing, "and you'll have to balance up the material to be excavated by a longer route against the cost of more improved land by one that is more direct." "How much power is required?" The question came dully. "Not less than thirty thousand. I'm going to make carbide.
Hastily he shot through the crowd, organizing the bucket brigade and searching for news of the Argonaut pump, which had not yet arrived. Half-disgusted, Fairchild turned and started up the hill, a few miners, their carbide lamps swinging beside them, following him. Far in the rear sounded the wails of Sam Herbenfelder, organizing his units of search.
Tell me what you know; and no more!" "Yes, sir," ventured Herzog. "There are three processes to extract nitrogen and oxygen from air. One is by means of what the German scientists call Kalkstickstoff, between calcium carbide and nitrogen, and the reaction-symbols are " "No matter," Flint waived him, promptly. "I don't care for formulas or details. What I want is results and general principles.
