...they circulated growth-activating fluids which Dr. Lillian Eloise Baker of the Rockefeller Institute supplied them, containing blood serum, insulin, thyroxine, vitamin A, vitamin C, etc. The ''lungs'' of the apparatus refreshed the "blood" with a steady injection of air composed of 40% oxygen, 3% carbon dioxide, the balance nitrogen. The whole apparatus was kept at blood heat in an incubator, was rocked so that "blood" pulsed through the organ, almost exactly as in life...
...myth has it that neither Mr. Weber nor any of his directors had ever been inside Allied's great atmospheric nitrogen works at Hopewell, Va. A more authentic tale is that, while in Germany, Mr. Weber politely refused an invitation to inspect the famed nitrogen fixation plant of I. G. Farbenindustrie because he felt he could not return the courtesy. Instead he tramped some five miles around the plant -outside...
When a normal person becomes unconscious from breathing too much nitrogen, faints from low blood pressure, or simply goes to sleep, the fast small waves on the chart are replaced by large slow waves, one to five a second...
...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...
...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...
