...Tousled, belligerent Yandell Henderson has concentrated on poison gases, of war and peace. During World War I, Professor Henderson (with his assistant, Howard Haggard) invented a gas mask, but his greatest scientific work is his research on respiration. Physiologists long believed that asphyxiation was caused by lack of oxygen plus an accumulation of "poisonous" carbon dioxide in the body. The old method of resuscitation was to pump pure oxygen into lungs. But this method was seldom successful. Professor Henderson proved that carbon dioxide in small amounts is really an essential breathing stimulant, introduced an O 2 -CO 2 mixture which...
...trouble is in man himself. Man has been surpassed by his machines. Even pure oxygen cannot ward off bad muscular coordination; and the body and brain become weary, slow down above 35,000 to 40,000 ft. The human body, which lives a hand-to-mouth existence at any altitude, stores up little or no oxygen. The greatest hazard for altitude airmen is their conviction that they are perfectly all right when a reduced oxygen supply actually makes them act silly...
Experiments detailed in a new issue of the Journal of the Aeronautical Sciences showed that 44,000 ft., with oxygen masks, is probably the absolute upper limit for flying. In a low-pressure chamber which reproduced conditions at that altitude, subjects passed the limit of effective activity, were in a precarious state. For all practical purposes, the limit is below...
Intercooler. Not only oil but air has to be cooled for airplane engines. To supply enough oxygen for an engine at high altitudes, compressed air has to be blown into its carburetor. Though air may be as cold as -40° F. when sucked into a supercharger (TIME, Aug. 18), it often heats up to 450° F. upon compression, and must be cooled to between 30° and 100° F. before it is fed to the carburetors. The coolers used are simply air scoops which pour wind around small pipes carrying the hot, supercharged air. Intercoolers on early...
Record. In Middletown, Conn., Wesleyan University Junior Eugene J. Frechette Jr. breathed deeply for three minutes, took three breaths of oxygen, then sat purple-faced, breathless, like-to-bust, for 20 min., 5 sec. When he finally let go, he had broken the known world's record...
