...occasion, and at the entrance to a hole dug in the ground, a colonel of the Russian signal corps was on hand to explain it all. Ten feet below, its entrance a hole cut in the roof by the Russians, lay the tunnel itself: a cast-iron tube about six feet in diameter and 500-600 yards long, crammed with electronic equipment, cables, tape recorders, ventilating apparatus and pumps of both British and American make. At the East German end, cables led out of the main body of the tunnel to a separate chamber where they were linked...
...reach the necessary high temperature (millions of degrees) without melting or vaporizing the walls of the container. Kurchatov told how Russian scientists experimented elaborately with one of the most promising methods, the "pinch effect." When a powerful electric current is sent through an ionized gas in a tube, it creates a magnetic field that compresses the gas into the tube's center, keeping it away from the walls...
Scientists of all countries know about the pinch effect, but their work with it has been minor, or is still secret. According to Kurchatov, the Russians made a big effort and got some remarkable results. By sending very heavy currents in short pulses through tubes containing such gases as deuterium (heavy hydrogen), they concentrated the gas in the center of the tube and held it there for an appreciable instant, while its temperature rose toward...
Baschet's first musical invention was a collapsible guitar, built around an inflatable plastic cushion. It has a soft, seductive tone, can be deflated or patched like an inner tube. "After I invented it, I wanted to know why it worked," he explains. The search led him to Paris' National Library and books of 19th century acousticians, e.g., Helmholtz. Their theoretical discussions flashed through Baschet's teeming imagination and emerged as sounds-new sounds of otherworldly groans, melodious thuds and haunting echoes, which came from the vibrations of two metal spirals plus a plastic resonator. Baschet took...
...first-quarter earnings reports (see below), other companies voiced their confidence in the increasing appetite of the growing U.S. population. B. F. Goodrich Chairman John L. Collyer announced a $200 million plant expansion in the next five years, nearly $60 million more than in the last five. Youngstown Sheet & Tube, already committed to a $40 million outlay in two years, is pressing so hard to keep up with rising steel demand that it is considering tacking another $20 million onto the total...
