Ultrasonic machines are used for hospital and industrial cleaning and degreasing. They can join metals previously impossible to weld or solder, drill square and other odd-shaped holes in brittle materials, such as germanium and glass. They will measure any liquid, including exotic jet fuels, and liquid oxygen in rockets. The aircraft, electronic and missile makers have been a major spur to the growth of ultrasonics. Before the development of ultrasonic cleaners, jet-engine nozzles and oil filters had to be thrown away when dirty. Now imbedded residue can be removed in minutes through the use of sound energy...
...really dependable safety device, say Huston and Miller, should tell on its own when the reactor is starting an excursion. The best way to trigger its action is to combine a pad of material containing uranium with a layer of high-melting solder. When the neutrons in the reactor rise above a critical level, showing that an excursion has started, the uranium fissions at a rate that creates enough heat to melt the solder. Then high-pressure gas will shoot neutron-absorbing poison into the reactor. Even if other controls have failed, this last-ditch nuclear fire extinguisher will keep...
...Stanislaus Danko. 41, and Moe Abramson, 45, career employees at the Signal Corps Engineering Laboratories at Fort Monmouth, N.J. Their idea: an automation process that punches holes in regular printed or etched electronic circuits, drops the leads of components (resistors, tubes) through the holes, dips the leads in a solder bath, soldering all connections in one operation. The Government made the system available free to electronics firms, saved $4,200,000 in lower prices for electronic circuits in its first year of operation. The awards reflected the continued appeal of the incentive policy; last year the Government received...
...instruments, batteries and components of the small radio transmitter that will send information back to earth. When ready for space, the magnesium will be plated, first with gold, then with aluminum, then with a final thin layer of a silicon compound. Small amounts of gold will be used as solder to stick the magnesium and aluminum together...
...Fastened upon the canvas are such 'found objects' as cheesecloth, string, mud, sand, scraps of cardboard, fragments of mirrors, broken bottles and tennis shoes . . . Sculpture has given way to constructions where 'found objects' of junk yards are welded together in fantastic arrangements with droolings of solder . . . Work dealing with decay, destruction, fragmentation, explosions and torture are frequent. Apparently it is stylish to make a negative rather than an affirmative statement about life-and easier . . . Chicago is not that sick...
