Cooler Tooler. For tooling tough alloys, Britain's Impregnated Diamond Products Ltd. began sale of Sparcatron, a device which uses an electrical charge instead of diamond-edged tools to machine metals to tolerances as close as one-twenty-five-millionth of an inch. Sparcatron generates no heat (which may make the conventional cutting tool inaccurate) and has no cutting edge to get dull. Price: about...
...pulses of electricity to the dots on the crystal. Each dot absorbs more or less electricity according to whether it is charged or not. Sensitive relays measure the flow of current and report whether each dot is a one or a zero. This process, which takes less than a millionth of a second, is the equivalent of the human brain's "bringing something to mind...
Last week the 125 millionth Perk label came into the foundation's Chicago office. And out from Staffel went another check, bringing the total of profit payments since...
...lines must be straight and the same distance apart within a tolerance of less than one millionth of an inch, and to make an "engine" rule them with this extreme accuracy is fantastically difficult. When measured by these high standards, even massive steel bars seem as flexible as rubber. Thin films of oil are as yielding as deep quicksand. The slightest change of temperature makes the machine change its dimensions and thus rule the lines askew...
...whole field of vitamins, Merck's greatest triumph, by far, is its most recent. Its chemists extracted the elusive anti-anemia factor from liver in pure form: the ruby-colored crystals of vitamin B12, essential to growth and the most powerful medicinal substance known in nature. One thirty-millionth of an ounce a day is enough for a healthy man's blood-making factory; one three-millionth checks pernicious anemia...
