The five antibiotics were used as supplements to an all-plant-protein ration, and also to an all-plant protein ration in which 2.5 per cent fish meal replaced a like amount of high protein soybean oil meal. Except for bacitracin, which was a purified concentrate, all antibiotics were pure crystalline materials. The levels used were approximately 9 grams of each antibiotic per ton of feed.
Anion Exchange Resins As Condensation Catalysts
Some of the specifications involved include: JAN-L-73 Lacquer enamel, lustreless; JANE-74 Enamel, lustreless, quick drying; MILP-6889A Primer, zinc chromate; MIL-E-10687 (Ordnance) Enamel, lustreless, quick drying; MIL-E-15090, E n a m e l , e q u i p m e n t . Local U.S.I, technical representatives have complete information on these specifications and also on any of the other important government issues.
Man-Made Flames Equal Heat of Sun's Surface Controlled flames, said to be as hot as the surface of the sun or of the hottest known stars, have been produced in the laboratory for the first time. An inch-long flame of hydrogen and fluorine is reported to have reached temperatures of 9,000 °F. and to have burned through a quarter inch of zirconium oxide in 30 seconds. A larger flame of oxygen and aluminum burned through a three-quarter inch steel pipe in 15 seconds and through four inches of concrete in a little more than two minutes. Experimenters claim to have reached the sun's surface temperature of 10,000 °F. with a flame of hydrogen and fluorine in compressed air.
Anion exchange resins are commanding attention as catalytic agents for aldol condensations, il i s reported. These resins are claimed to ha've promoted yields of up to 60 per cent in theKrxoevenagel reaction, a general process for condensing carbonyl compounds with acids, cst-ers, nitriles, nitroparaffins. and other compounds having active hydrogens. The resins are said to act as true catalysts, remaining unchanged and suffering no loss in efficiency with repeated use. Of industrial interest is the fact that product recovery is simple and requires no costly catalyst neutralization.
