...this time U. S. Steel broke through 200, reeled down to a closing figure of 186. All the blue chips of the late bull market were hammered and sliced-the better the stock, the bigger the break. On this day A. T. & T. fell 24 points; Columbia Carbon, 61; Consolidated Gas, 20; Electric Power & Light, 13; General Electric, 47; Eastman Kodak, 41; Otis Elevator, 60; New York Central, 22; Montgomery Ward, 15; U. S. Industrial Alcohol, 39; Standard Gas & Electric, 40, etc. etc. etc. ... In Rio de Janeiro the coffee market already frightened (TIME, Oct. 21), closed altogether...
...Goddard, Clark University rocket inventor (TIME, July 29), disclosed his invention of a sun engine. His laboratory model consists of a parabolic mirror one foot in diameter, which focuses sunlight upon a hollow glass sphere five-eighths of an inch in diameter. The sphere contains water and finely divided carbon. The focused light passes through the clear water without heating it. But when the light strikes the opaque carbon, the carbon heats almost instantly and in turn heats the water, which turns to steam. The steam escapes through a hole in the top of the sphere, whence it could...
...practical operation Professor Goddard suggested last week a mirror 20 feet in diameter focusing on a boiler with a fused quartz base. The boiler would contain, instead of pulverized carbon, mercury sprayed continuously at the focus point of the reflected light. The mercury spray would turn instantly to mercury vapor and in turn vaporize the water which would operate a steam turbine. The turbine would operate an electric generator. Efficiency of such a sun engine would be 50% of the sun energy fused.* Professor Goddard calculates that such an engine would produce 30 h.p. while operated under a clear...
...steels contained small amounts of molybdenum. However, the presence of molybdenum was accident. Mineralogists did not recognize it as a metal until the 1790's. Metallurgists did not introduce its hardening properties to a steel alloy until very recently. Pure iron is a relatively soft metal. A little carbon added yields hard steel. Steel plus a trifle of manganese gives an alloy hard enough, when fabricated into rails, to support heavy subway traffic. If with manganese steel a bit of molybdenum is mixed, the alloyed steel is still harder. G. M. Eaton of Molybdenum Corp. of America advised railroads...
...Konel metal is not to be confused with monel metal, a copper-nickel alloy (plus small amounts of iron, carbon, manganese, silicon) developed in 1905. Monel metal is relatively soft, is valuable for its corrosion-resisting properties...
