Helium for Dizziness. The main trouble with deep diving is that when the diver breathes ordinary air under too much pressure, nitrogen dissolves in his blood and tissues, causing dizziness and other kinds of trouble. Below about 240 ft., the air pumped down to the diver is replaced by a mixture of oxygen and helium. The helium penetrates the tissues, but does not have the bad effects of nitrogen. When the diver comes to the surface, however, he must be decompressed slowly lest bubbles of helium give him painful, sometimes fatal "bends...
...parts) and helium (91.5 parts). Going down was comparatively easy. In spite of the 273 Ibs. of pressure on every square inch of his body (39,312 Ibs. per sq. ft.), he felt fine. "I felt no more effect from the helium," he says, "than I would from nitrogen at shallow depth. My mind was clear. I did the job I was sent down to do." His token job, to prove that he could do useful work, was to unbolt a wire...
...surface. Pound by pound its air pressure fell. As it neared the surface, Clucas closed the bottom door to hold the remaining pressure, and the chamber with the two men inside was taken on board the Reclaim. For an hour they breathed pure oxygen to flush residual helium and nitrogen out of their systems. Then the door was opened, and they stepped out. At once they felt the dreaded pains of the bends, Wookey in his shoulders, Clucas in his legs and chest. They ran into a larger decompression chamber, where they were kept under oxygen for four more hours...
...breathes a small proportion of all the molecules of nitrogen and oxygen are ionized by cosmic rays-they become positive ions if they lose an electron, negative ions if they gain one. Philadelphia researchers have found that almost two-thirds of hay fever victims won quick relief in air that was heavily negative-ionized, snuffled and sneezed far more in air that was artificially positive-ionized. As a result, Philco Corp. plans to market a negative-ionizing air conditioner. ¶Automobile-accident victims often report "brain concussions" and are admitted to hospitals for study, but in 30% of cases studied...
...Watkins, 18. of Denver. The son of a factory worker and a waitress, Ted worked his way summers as a dishwasher, salad cook, spray painter and apprentice engineer in a local rubber factory. In his spare time he puttered about his school laboratory over such experiments as determining the nitrogen in wheat and recovering the tin from tin cans. Had it not been for his $2,000-a-year scholarship. Ted could have earned a degree only by going to school at night. Now he is studying to be a chemical engineer at M.I.T...
