...ionized by solar ultraviolet light into positively charged nuclei and negative electrons. Theory suggested that at a certain altitude above the earth this charged plasma should have a sort of elasticity that would permit hydromagnetic waves to pass along it, rather like mechanical waves traveling along a coil spring. The Fort Monmouth scientists found that the Argus explosions started just such waves in a layer of plasma about 1,500 miles high. The waves were about 1,000 miles long, and they traveled at several thousand miles per second, spreading around the earth from the South Atlantic like ripples around...
...Hemp. In Seattle, the suburban Grinnell & McLean furniture store ballyhooed "Mother-in-Law Mattresses," sale-priced at $9.95, craftily explained to buyers: "After mother-in-law has gone home because of the mattresses' strange odor of miscured sisal, the handy homemaker can cover the otherwise-perfect 510-coil mattress so that it will give years of odor-free comfort and sound sleep...
...form a magnetic "mirror," which reflects back the charged particles as they try to escape, thus sealing the gas in a magnetic bottle. A bank of 99 condensers, kept in the basement since condensers sometimes blow up, sends a jolt of 4,000,000 amperes thundering through the coil, heating the gas up to around 20 million degrees. Dr. Kolb reported that his machine had confined plasma and kept it stable at this temperature for twelve microseconds. During this period, bursts of neutrons poured out of the device. "This agrees with theoretical calculations for a fusion reaction," said Kolb cautiously...
...Refrigerator. An auto refrigerator that holds eight 12-oz. bottles is being sold by Pol-Air, Inc., Morgan City, La. The device is cooled by a copper coil that is connected to the car's carburetor and gas line. The carburetor draws gas from the gas line through the coil, where it changes from a liquid to a vapor and in the process absorbs heat, then is fed back to the carburetor. Price...
...weight is suspended so that it holds still while the earth waves move past it. The slight motion between the weight and electrical elements close to it creates a fluctuating electrical current. Before the current reaches the recording apparatus Pomeroy and Sutton pass it through a special galvanometer-a coil that makes a small weight move against the resistance of a delicate spring. The waves in which they are interested are long and of low frequency (40 to 50 sec.). They found that by choosing a galvanometer with the proper relationship between coil and spring, they could mechanically "tune" their...
