Died. Dr. Francis William Aston, 68, British chemist who won a 1922 Nobel Prize for inventing the mass spectrograph, through which heavy water and uranium 235 (atomic bomb ingredient) were discovered; in Cambridge, England. He once warned against atomic tinkering: "All hydrogen on earth might be transformed at once, and this most successful experiment published to the universe [as] a new star of extraordinary brilliance...
...petroleum industry, better heatexchangers, new methods of separating gasoline fractions, better mass-spectrograph analysis...
Processes & Places. There were many possible ways of separating U-235 from natural uranium. Two processes at least were found to work well. In the first (mass spectrograph), uranium particles were electrically charged, fired through a huge electromagnet, sent into a curving course. The lighter U-235 swung more widely on the curve. Traps were set at the end of the turn, and U-235 was caught there, while U-238 was discarded...
...principle of the coronagraph (which resembles an anti-aircraft gun-see cut) is simple. A metal disc is placed at the focus of the telescope lens to cut out the bright sun image. A second lens focuses on photographic film the black disc and flaring corona, and a powerful spectrograph breaks up coronal radiation into its component colors. A moving picture camera can also be attached to the telescope...
Other equipment at the station will include a powerful spectrograph to observe the spectrum of the corona. Color filters as well as movies will be used to record how the corona changes from day to day and how its streamers project into space...
