I should explain that during previous months, thanks to the efficiency of the Committee of Twenty-one, great quantities of liquid chlorine had been manufactured at Niagara Falls, where the Niagara Alkali Company, the National Electrolytic Company, the Oldburg Electro-Chemical Company, the Castner Electrolytic Alkali Company, the Hooker Electro-Chemical Company and several others, working night and day and using 60,000 horsepower from the Niagara power plants and immense quantities of salt from the salt-beds in Western New York, had been able to produce 30,000 tons of liquid chlorine.
One of the most interesting of the many electro-chemical processes is the heating of lime and coke in the electric furnace so as to obtain a product in the form of calcium carbide, which, on solution in water, forms acetylene gas, a useful and valuable illuminant.
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.
Electric railway equipments of every kind, telephone stations for talking with wires and without 'em, all kinds of electric lighting, arc lamps, electro-chemical displays. And in one place they show the way Niagara wuz made to yield up her resistless power to work for mankind. Labratories for all sorts of electrical exhibits and research work.
Faraday's second group of researches and discoveries embrace the chemical phenomena of the current. The dominant result here is the great law of definite Electro-chemical Decomposition, around which are massed various researches on Electro-chemical Conduction and on Electrolysis both with the Machine and with the Pile.
The electric furnace enables various elements to be isolated, such. as silicon, sodium, and phosphorus, and when obtained in their pure state they find wide application. The most important electro-chemical work of the future is to devise some means of obtaining nitrogen from the air.
Quite recently, however, one of the electro-chemical companies at Niagara Falls has succeeded in commercially solving the important problem of the fixation of the nitrogen of the atmosphere; it being claimed that the cost of thus producing one ton of commercial nitric acid, of a market value of over eighty dollars, does not greatly exceed twenty dollars.
I could not now use the precaution in her case, which it had somehow seemed natural to adopt with Eivé, of marking the paper returned for erasure. On her part, Eunané thrust into my hand the whole bundle as they were, and I was forced myself to erase, by an electro-chemical process which leaves no trace of writing, the words of that selected.
You'll lose nothing by it. So no more of that. Show us what you've done. Everything all ready?" "Quite ready, sir," the other answered. "If you'll be so good as to step into the electro-chemical building?"
His by-hours were spent in a little workshop he had opened. Among his inventions at this period were a dial telegraph, and a 'printer' for use on private lines, and an electro-chemical vote recorder, which the Legislature of Massachusetts declined to adopt. With the assistance of Mr.
