...discovery of a flame hotter than hydrogen burning in oxygen (oxy-hydrogen). He made atomic hydrogen burn in an atmosphere of molecular hydrogen. His hydrogen blowtorch melted tungsten wire like an icicle, indicating that its heat was at least 7,000° F. Playing on a sheet of chrome steel the flame left molten pools behind it. Significance: steel girders could be welded silently instead of noisily riveted;* the welds would not (as when an oxyhydrogen flame is used) be oxidized and thus weakened, they would be annealing instead. This is important in joining aluminum, magnesium and other light metals...
That may well be within reason, for they have been able to loan money, with profit to themselves, at 2% interest. That was how they could prevent Dillon, Read & Co.* from underwriting all the $60,000,000 bonds of the newly organized German United Steel Works-the consolidation of Thyssen, Phenix, Rheinstal, Deutsch-Luxembourg steel corporations (TIME, July 5). They permitted Dillon, Read to take only one-half of the offering. They took the other half themselves...
...workmen. At his death in 1902, he was succeeded by his elder and able daughter Bertha who in 1906 married Dr. Gustav von Bohlen und Halbach. At that time, Germany was just getting into her stride in the naval competition with Great Britain, and the demand for steel was enormous. Before the War, visitors to Essen stood aghast at the monstrous flame-belching foundries hastily proceeding with their grotesquely demoniacal output. And during the War Frau Bertha Krupp von Bohlen was undoubtedly the most potent female defender of the Fatherland...
Machine builders have always wanted a steel that had a soft core with a hard surface or "skin." Such a steel would furnish an enduring wearing surface and yet be easy to shape. It would be invaluable to makers of motor cars, typewriters, adding, sewing, knitting machines-wherever wearing parts are needed. Metallurgists have produced soft, shapable steels. They have devised hard steels which were expensive to "work." But not till last week did any one announce a steel with all the desiderata of the machine builder...
Metallurgists for the Jones & Laughlin Steel Corp. of Pittsburgh have devised this new steel, which they have named "Jalcase." It possesses a "triple combination of fast machining, casehardening and forging properties...
