Page 101 - IN WROUGHT IRON. is not very marked in the ordinary puddling process. It seems to add somewhat to the strength of the iron, but the amount is not of sufficient value to induce the general use of aluminum for this purpose. The peculiar property of aluminum in reducing the long range of temperature between that at which wrought iron first softens and that at which it becomes fluid, is taken advantage of in the wellknown Mitis process for making "wrought iron castings.

Page 220 - To find the capacity of a cylinder in gallons: Multiplying the area in inches by the length of stroke in inches will give the total number of cubic inches ; divide this amount by 231 (which is the cubical contents of a gallon of water) and quotient is the capacity in gallons.
Page 99 - The addition of aluminum in quantities of from 2 to 3 lbs. per ton is of advantage where the steel is to be cast in heavy ingots which will receive only scant work. Here it seems to increase the ductility as measured by the elongation and reduction of area of tensile test specimens, without materially altering the ultimate strength. The...
Page 218 - Atmosphere tit the rate of 650 feet per second. The specific gravity of steam (at atmospheric pressure) is .411 that of air at 34° Fahrenheit, and .0006 that of water at same temperature. 27,222 cubic feet of steam, at atmospheric pressure, weigh i pound : 13,817 cubic feet of air weigh I pound.
Page 13 - ... 500° F., although this loss of strength is only while the metal is kept at the high temperature. It serves as an annealing operation, and reduces permanently only the higher tensile strength produced by cold rolling or otherwise cold working the metal. Aluminum does not volatilize at any temperature ordinarily produced by the combustion of carbon, even though the high temperature be kept up for a considerable number of hours.
