...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...
...both the U.S. and Europe, is an intricate but efficient machine, 5 in. long. Provided that the blood vessel to be rejoined has free ends about ¾ in. long, the machine grasps the ends, turns back a piece to make a cuff on each, then joins the cuffs with tantalum wire staples. The inside bore of the vessel is not reduced, permitting full blood flow. The surgeon can do the stapling in one minute...
...work as a companion to the transistor. About as big as a kernel of corn (and about a quarter the size of the smallest capacitor G.E. has turned out so far). the new capacitor can store energy and release it later when needed. Made mostly of silver and tantalum, it filters electric current, eliminating interference and improving the tone of such devices as miniature radios and hearing aids. Price: about...
...Tulane University neurosurgeons described a simple and seemingly successful way of treating syringomyelia, an uncommon but hitherto baffling complaint in which a cyst forms in the spinal cord, gradually causing paralysis. The technique involves using a wire of the modern wonder metal, tantalum, to keep the cyst open and draining. Unlike materials previously used, tantalum does not change in the body or interfere with body tissues. Three living testimonials appeared at the New Orleans meeting...
...every two men will have lost all his teeth or will be suffering from a disease of the gums or jawbone. For the toothless unfortunates, Dentists Stanley ]. Behrman and George F. Egan described a new method of locking false teeth in place with magnets. Protected by plastic and tantalum mesh, the magnets are imbedded in the jawbone and lock tight against similar magnets built into the denture...
