...great airdock at Lakehurst, idle since the Akron and Macon disasters. To permit the vast Hindenburg to fit the Lakehurst hangar, Dr. Eckener removed two ribs, thus shortened her seven feet. Even so, she is 803 ft. long, 135 ft. high, holds some 7,000,000 cu. ft. of hydrogen, has nearly twice the bulk of the old Graf Zeppelin...
Rubber, silk, cellulose and certain other organic compounds contain "giant molecules" weighing hundreds of thousands and even millions of times as much as the hydrogen atom. The rayon industry (which last year produced more than 256,000,000 lb. of fabrics, employed 60,000 workers and paid them $60,000,000) is currently profiting by a clearer understanding of these mammoth particles. It has been found that cellulose molecules in cotton are chains of 3,500 links. Such long molecules could be seen under the microscope if they were fat enough. The new artificial fibre is built on the same...
...Antidote. Rats were poisoned by carbon monoxide to the point of cyanosis and respiratory convulsions. When hexahydroxyferric chloride (a reaction product of ferric chloride and hydrogen peroxide) was injected into their bellies, 75% recovered.-Sam & Joseph Seifter of University of Oklahoma's School of Medicine...
...Okla. 29 years ago, got his Ph. D. at 23 from Massachusetts Institute of Technology, and is now an assistant professor at Cornell. Of little interest to laymen, Dr. Kirkwood's work on the dielectric properties of gases under pressure and on polarization phenomena in methane, nitrogen and hydrogen provided invaluable working tools for chemists. Said the award committee: "He succeeded in instances where older and more experienced men of proved ability have failed to arrive at definite results...
...join these terrific speeds and pressures, Scientist Svedberg enclosed his rotor so that it spins in hydrogen reduced to 1/30 atmospheric pressure. Driving mechanism consists essentially of two turbines, the size of thread spools, against which oil is pumped at 800 lb. per sq. in. pressure. To prevent overheating of bearings, 45 minutes are required to work the rotor up to operating speed, 45 minutes more to slow it down. The rotor is oval in shape because an oval is less likely to fly apart than a circle...
