...research is made possible through the development of an "electron bombardment" furnace, in which metals have been heated, without contamination up to temperatures of bout 1500 degrees Fahrenheit, or nearly half that of the sun. Much higher temperatures could be easily reached by this apparatus, the Harvard scientists...
...only factor limiting the temperature in the new Harvard furnace is the melting point of the crucible. The best crucibles obtainable at present are made of tantalum, lined with thorium oxide. Both substances melt at about 5000 degrees Fahrenheit...
...experimental tests Dr. Hultgren has successfully molted iridium at 4230 degrees Fahrenheit; platinum at 3200 degrees; and pallodium at 2790 degrees. Ruthenium was heated to 440 degrees Fahrenheit and "sintered" a little but did no melt...
...bulky, air-tight suit climbed almost ten miles up into the stratosphere. He was Colonel Mario Pezzi, commander of the military altitude school at Montecarlo, Italy. In his Caproni biplane with its 14-cylinder, 700-h.p. Piaggio engine, he encountered temperature as low as 65.2° below zero Fahrenheit, but got back to earth without trouble and with a new world record...
...flight began immediately after the regular weather airplane run from the Boston airport, which reported a temperature of 9 below zero Fahrenheit at a height of 17,000 feet, as high as the plane went...
