Page 863 - Manganese.—Each 0.01 per cent. of manganese has a strengthening effect upon steel, and the effect is greater as the content of carbon increases. Below a certain content of manganese the effect is complicated by some disturbing condition, probably iron oxide, so that a decrease in manganese in very low-carbon steels is accompanied by an increase in strength.
Page 512 - Gold Assaying. A Practical Handbook giving the Modus Operand! for the Accurate Assay of Auriferous Ores and Bullion, and the Chemical Tests required in the Processes of Extraction by Amalgamation, Cyanidation, and Chlorination.

Page 569 - Whatever is intended for insertion must be authenticated by the name and address of the writer, not necessarily for publication, but as a guarantee of good faith.
Page 807 - The failure of the wheel itself was due to a gradual opening of the joints, occasioned by the fracture of the outside prisoners and to flaws in the bronze castings of the arms near their junction with the rim. On putting the pieces of the wheel together in their original order it was easy to locate the joint which first gave way, on account of the symmetry of the breaks either side of a diameter through this point. It is but fair to the builders of the wheel to say that the fractures showed uniformity...
Page 531 - That when shown through fixed lenses, as arranged in the experimental towers, the superiority of the super-posed gas light is unquestionable. The larger diameter of the gas flames, and the lights being much nearer to each other in the gas lantern, give the beam a more compact and intense appearance than that issuing from the more widely separated oil burners.
Page 598 - ... dependent on the caprice of the atmosphere. The desiccation of the air used in blast-furnaces in such a way as to reduce its moisture to a small quantity, and to keep it uniform, must of necessity contribute in a very marked degree toward the attainment of uniformity in the furnace-operations.

Page 531 - That the electric light, as exhibited in the A experimental tower at South Foreland, has proved to be the most powerful light under all conditions of weather, and to have the greatest penetrative power in fog. " (2) That for all practical purposes the gaslight, as exemplified by Mr.
Page 598 - The advantages from desiccation can be appreciated only after due consideration is given to the volume of air that is consumed per minute and the large amount of moisture which it contains. Managers of blast-furnaces are familiar with the...
