...water. This is converted by the reciprocating-engine principle into a pump action, giving pulsatile pressure in four Plexiglas chambers. In each of these is a rubber bladder corresponding to one of the heart's own chambers. The bladders are paired (like the auricles and ventricles) and they contract and expand in a rhythm like the heart's. In an additional chamber, corresponding to the lungs, the blood is oxygenated by the conventional film-on-screen method...
...satellite isn't going to know whether the re-entry system really works. That's why we need a test-pilot type-daredevil but stoic." The first stoic satellite daredevil has not yet been picked, but last week the National Aeronautics and Space Administration signed a contract (see BUSINESS) for the hollow, upholstered meteorite in which he will ride...
SNAP III was developed under a modest $15,000 AEC contract with the Martin Co. of Baltimore working in conjunction with the Minnesota Mining & Manufacturing Co. But the polonium, which is made by radiating bismuth in an atomic pile, costs about $10 per curie. SNAP's charge is the equivalent of 3,000 curies, bringing the price of fuel in the capsule to $30,000. An AEC official explained that some cheaper isotope might later be substituted for polonium. If cerium 144 can be used, the unit cost might be as low as $600 per battery...
...coveted Government contract for the first space capsule designed to carry a man into orbit around the earth (see SCIENCE) went last week to St. Louis' McDonnell Aircraft Corp. The contract itself was modest-only $15 million-but the prestige is enormous. Twelve topflight companies submitted plans and bids on the project. McDonnell won because its president, James S. (for Smith) McDonnell Jr., and his engineers had long since anticipated the Government's needs. They had been working on the project with their own money for more than a year, before the Government decided to go ahead. When...
Dean Watson called the duel "most deplorable," and said that the "corral," which had been intended as a mating pen for the Chinese dragons, had "tasted sin." Watson indicated, however, that Hall's grade would be raised. "The University can do nothing to impair the obligation of contract," he said...
