...negotiators prepared to resume the suspended talks at Geneva, word leaked of a report submitted to President Eisenhower which concludes that U.S. seismologists have achieved considerable success. Though the report itself is still secret, one major improvement has been sacrificed by its inventors-Paul W. Pomeroy and George H. Sutton of Columbia University's Lamont Geological Observatory...
...type of seismograph in which a heavy 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...
Jumbles Made Sharp. The result was magical. Seismograph records that were hardly more than meaningless jumbles turned into clear, sharp records of distant earthquakes. When Dr. Sutton showed these records to a recent Washington meeting of seismologists, the contrast was so striking that the sophisticated audience burst into applause...
Pomeroy and Sutton are guarded about the effect their filters will have on international networks for detecting underground nuclear tests. They calculate that six stations equipped with the new instruments could detect most underground disturbances anywhere on earth that have the energy of a "nominal" (20-kiloton) nuclear bomb. Between 20 and 50 stations (v. the presently postulated 180) would be required not only to detect but also locate such disturbances. They are not prepared to estimate just how many more would be required to detect explosions of bombs as small as 5 kilotons or how accurately they could distinguish...
...instrumented payload) of Sputnik III proved to the space-wise that the Russians had practically licked the initial problems of interplanetary flight. U.S. scientists reckon that the Soviets' Lunik, with only a little more speed, would have swooped past Mars and soared out toward the asteroids. George Paul Sutton, professor of aeronautical engineering at M.I.T., believes that present propulsion systems with a little refinement can send a space vehicle as far as Jupiter or even to Saturn, 750 million miles from the earth...
