...only does Chemico's process promise to boost the output of cobalt, but Engineer Roberts says it works equally well with other low-grade ores such as nickel, copper and manganese (but not as yet with iron ores). Moreover, by reducing the amount formerly lost in slag, he says it can increase the pure metal recovered from scrap as much as 15% for copper, 70% for zinc. He predicted it could eventually cut the production costs of cobalt up to 80%, copper and nickel as much...
Bell Telephone's labyrinth is about half as big as a desk top and is fitted with aluminum partitions which can be shifted around among 40 different slots. Theseus himself has only a mouse-shaped wooden body, three small wheels and whiskers of copper wire. Inside him is nothing but a bar-magnet. His brains are outside him, under the floor of the labyrinth. They are a complicated array of relays...
...Shannon sets up the labyrinth in a pattern unfamiliar to Theseus. Then he places his mouse at an arbitrary point on the metal floor. At first Theseus does not behave very intelligently. He blunders around, bumping his copper whiskers against the aluminum walls. When he hits an obstacle, he turns away and tries it again. By such trial & error, Theseus finally gets through the labyrinth and ends the play by touching the "cheese," an electrical terminal that rings a bell...
...Only the merest traces of copper are normally found in the body, and not much has been known about what the copper does. Investigators from Salt Lake City offered a surprising answer: the copper is essential to proper use of iron; without it, animals (and probably humans, too) become anemic...
...fits & starts, the Administration has been working toward decontrol for weeks: voluntary credit control programs for banks have been suspended; some commodities have been freed from price control; additional quotas of steel, copper and aluminum have been allowed for consumer goods and commercial construction. But the Administration still clings to such measures as Regulation X, which restricts credit for homebuilding. One result of this: the construction industry is not absorbing its full share of structural steel (see Steel). And the Administration still hesitates to remove controls from many important commodities...
