...alloys were subjected to the pressure tests. They were commercial duraluminum, three aluminum alloys, a lead-calcium alloy, and an iron nitrogen alloy. Each alloy was submitted to the proper temperature, for the time necessary to insure complete solution of the precipitant. It was then quenched in water. The hardness was immediately taken. The alloy was permitted to age at room temperature, one series under high pressures, and a second series at ordinary pressures. After aging for definite time periods, hardness tests were again made...
...effects of pressure on the age-hardening period were most marked in the lead alloy; the aluminum alloys came next; while the iron nitrogen alloy was not affected even when pressure was run up to 20,000 atmospheres...
Since lead is the most compressible of the three metals, and iron the least, Dr. Wert notes that this relative compressibility might be thought to explain the nature of his results although "one would hardly anticipate from their comparative values that the lead alloy would be many times as sensitive to pressure effects as are the aluminum alloys or that the iron nitrogen alloy would show,--if, indeed, it shows anything,--a sensitivity so small as to escape detection by the usual Rockwell hardness tester...
...choosing two who performed on the same world stage about the same time. In The House of Rothschild (in which Wellington was impersonated by C. Aubrey Smith), Actor Arliss suggested to cinema audiences that Waterloo was a minor crisis in the affairs of a Jewish financier. In The Iron Duke, though Rothschild does not appear at all, Arliss' invariable mannerisms are so reminiscent that it seems strange when he orders his cavalry to charge instead of trying to arrange a merger. Whatever the effect of The Iron Duke may be on Mr. Arliss' ambitions for knighthood...
...when the brisk, tough-thewed, iron-haired ex-banker began to talk business, it was clear that he had by no means lost the spirit which once prompted him to defy the Federal Reserve Board. With a gardenia in his lapel, faultlessly dressed in a dark grey suit, starched collar and pepper-&-salt cravat, he displayed the same earnest optimism which helped make his bank for a few years the biggest in the U. S. Cried...
