Electron Cutter. United Aircraft Corp.'s Hamilton Standard Division (propellers) will put on the market a machine, developed by West Germany's Carl Zeiss Foundation, that uses electron beams to weld, mill and drill hair-fine holes in the hardest known materials, e.g., quartz, tungsten, zirconium. An electron gun fires beams that boost the temperature on the surface of the material up to 11,000° F. ; it can cut 100 holes in a straight line across a pinhead, drill a sapphire watch bearing in six seconds, weld a tough nu clear reactor core.

...difficulties are so great that no one knew whether such an engine would work at all. The reactor must run extremely hot; otherwise the hydrogen will not form an effective gas jet. Thus Kiwi-A's innards are probably made of tricky, heat-resistant metals such as tungsten, tantalum and molybdenum. Control is far more difficult than with chemical engines, because the flow of hydrogen must be balanced perfectly against the production of energy by the reactor. A slight maladjustment of the controls might melt the nuclear engine in seconds or blow it to smithereens...
...Devaluate the peseta and abolish the multiple exchange rates. (Mercury exporters get 31 pesetas for a dollar, tungsten exporters 90. Paris black-marketeers 60. The official rate...
...Arkansas, instead chose a 21% higher bid from Philadelphia's Baldwin-Lima-Hamilton Corp., thus giving some political help to Republican Congressman Hugh Scott (TIME, Feb. 2). Last week the coalmen demanded still tougher controls on imports of residual fuel oils, arguing "national defense." Lobbyists for cobalt, fluorspar, tungsten (which are already heavily stockpiled) and such debatable defense needs as dental burs and wool knit gloves are also clamoring for OCDM to squeeze off imports...
...Crucial Question. While making his subjects more malleable under the never-ending blows of the Communist hammer, Mao also went to work on the Chinese economy. In exchange for technical help and machinery, he shipped out to Russia antimony, tin, tungsten and, above all, desperately needed food. Of the $2.2 billion in "aid" that China has received from the U.S.S.R. since 1950, almost none of it was a genuine gift; the $300 million surplus that China expects to run this year in its trade with the U.S.S.R. will go to pay off past Soviet loans...
