Kaiser engineers also had trouble with Austrian Inventor Fritz Hansgirg, who kicked at changes in his carbo-thermic process. The U.S. took "Herr Doktor" into custody as an enemy alien in December 1941: Permanente barged ahead. To prevent explosions, Kaiser engineers soaked the magnesium dust in oil; to cut costs and save handling they started using petroleum coke (which contains pitch) instead of coke and pitch; to keep the furnaces going they invented new heat-resistant parts...
When FBI's roundup of aliens last week caught Austrian-born, magnesium-wise Dr. Fritz J. Hansgirg at the Permanente Magnesium plant near San Francisco, rumors spread at once that Permanente 's magnesium-making might have to cease. They were false...
...Fritz Hansgirg was the inventor of the Permanente process (TIME, March 3), and his arrest caused Permanente inconvenience. But he was only one of a staff of 180 technicians, consultants, engineers. Production, said Permanente Owner Henry J. Kaiser, would go on. But, he added, "we feel that it is important that Dr. Hansgirg's status be promptly developed. . . ." Fritz Hansgirg had built Hansgirg-process plants in Austria and Korea before coming to the U.S. in 1940. After making his patents available to Henry Kaiser, he helped to plan the West Coast concern. An Austrian citizen, he was high...
...variation of this process is being perfected by Metallurgist Henry Alfred Doerner of the U.S. Bureau of Mines who claims that when a chill spray of oil is substituted for the Hansgirg cooling gas the magnesium is rendered nonexplosive by an easily removable oily film which forms on the powder grains. The process has been developed at Washington State College and will probably be used in a 12,000-ton plant at Spokane where magnesium deposits adjoin Grand Coulee's cheap power...
...backers of both these processes hope to get magnesium for 12?, 10?, perhaps even less a pound. Dow is skeptical about the Hansgirg process (Dow turned it down), but Dow itself has cut the price of magnesium from $5 in 1915 to 50? in 1925 to 30? in 1931 and is said to have sold magnesium to Germany before the war as low as 21? a lb. Dow's magnesium costs are inextricably tied up with other chemicals, notably bromine, which are recovered simultaneously. If some of Dow's first costs can be written off against emergency production...
