"Ferro-" Quotes from Famous Books
... manufacture of steel, the application of the electric furnace for producing what are known as ferro-alloys, or alloys of iron, silicon, chromium, manganese, tungsten and vanadium, is now a large and important industry. Special steels have their uses in different mechanical applications and the advantage of alloying them with the rarer metals has been demonstrated for several ... — The Story Of Electricity • John Munro
... large magnet belonging to the Royal Society, yet they were all ultimately repeated with a couple of bar magnets two feet long, one inch and a half wide, and half an inch thick; and, by rendering the galvanometer (87.) a little more delicate, with the most striking results. Ferro-electro-magnets, as those of Moll, Henry, &c. (57.), are very powerful. It is very essential, when making experiments on different substances, that thermo-electric effects (produced by contact of the fingers, &c.) be avoided, or at least appreciated and accounted for; they are easily distinguished ... — Experimental Researches in Electricity, Volume 1 • Michael Faraday
... of course, upon the purpose to which the steel is to be put. Rails, for example, must, above all, resist abrasion, and consequently have a higher carbon content than, say, reinforcing bars for concrete work. To obtain various qualities in steel are added carbon, ferro-manganese, or ferro-silicon in proportions differing according ... — American Adventures - A Second Trip 'Abroad at home' • Julian Street
... internal diameter, and graduated into one-twentieth c. c., which allows of great exactitude in the determination. For a spiegeleisen not more than 1 gramme of the sample should be taken, and for a ferro-manganese 0.3 gramme. ... — Scientific American Supplement, No. 401, September 8, 1883 • Various
... emerge. Discouraged by the reception of his experiments, Mr. Crosse soon discontinued them; but they were some years after pursued by Mr. Weekes, of Sandwich, with precisely the same results. This gentleman, besides trying the first of the above substances, employed ferro-cyanet of potash, on account of its containing a larger proportion of carbon, the principal element of organic bodies; and from this substance the insects were produced IN INCREASED NUMBERS. A few ... — Vestiges of the Natural History of Creation • Robert Chambers |
