...Shen; encyclopedias and newspapers: stainless steel or Monel metal models of furniture, printing presses, automobiles, airplanes, typewriters, etc.: a film projection machine with instructions for its operation; specimens of food, drink and chewing gum. Perishable materials might be sealed in an atmosphere of inert gases like neon or argon...
...natural atmospheric mixture of about 79% nitrogen, 20% oxygen and 1% other gases. After twelve years of smothering rats, monkeys and guinea pigs in various artificial atmospheres ranging from pure helium to nitrous oxide, Dr. John Willard Hershey of McPherson College reported that a mixture of 75% argon and 25% oxygen enabled the animals to get along as well as usual, that in 50% helium and 50% oxygen they were apparently more healthy and vigorous than in natural...
...special stopcock-sealing grease that boron trifluoride would not attack, a system of magnetically controlled rods for stirring his mixtures in closed vessels. Every time he generated the trifluoride he washed the maze of tubes, flasks and stills 20 times with air which had been freed of carbon dioxide. Argon 99.9+% was repeatedly distilled for further purification and the boron trifluoride was cleaned until it showed pure in the spectroscope...
...mixture of gases is cooled under pressure, the freezing point will be raised as the pressure is increased until the mixture becomes a real compound, beyond which point pressure increase has no effect. On this basis, trying different proportions of argon from 1% to 60%, the chemists found six plateaus on their graphs of freezing points which indicated six unstable compounds of argon, containing, respectively, one, two, three, six, eight and 16 molecules of boron trfliuoride...
...last week, Dr. Booth croaked jubilantly: "While we were led to the discovery of the argon-fluoride compounds for scientific reasons, we are studying certain possible applications but are not yet ready to discuss them...
