...Electrically Suspended Gyro). Like all the gyroscopic equipment that guides modern missiles, ships, aircraft and spacecraft, ESG's performance depends on the fact that a rapidly spinning rotor tends to maintain an unchanging attitude in space; it sticks to its stance regardless of the movement of the vessel on which it is mounted. Gyros that can do this job accurately for short periods are not too hard to build. But when a gyro is used steadily for days or weeks at a time, it tends to drift from its proper direction, usually because of friction in its bearings...
...hearings continued, so did the search for Thresher. The oceanic research vessel Atlantis II dropped cameras to see if one of a half-dozen ocean-bottom sonar "protuberances" might be the hull of Thresher. The bathyscaph Trieste, capable of plumbing depths of 35,000 feet, arrived in Boston, from where it would be shipped to seek the submarine's grave. And, for whatever reassurance it might be to men who serve aboard nuclear submarines, Rear Admiral Ralph K. James, head of the Navy Bureau of Ships, said that his experts were reviewing the design of Thresher class submarines...
...pioneering in heart surgery has been done away from the Brigham, though some of it only a block away at Children's Hospital. There in 1938, Dr. Robert E. Gross led the way toward heart surgery with his pioneering patent-ductus operation (to shut off a vessel that is necessary during fetal life, but should close automatically soon after birth). He followed this with a more daring operation in 1946 to remove a narrowed section of the aorta-a crippling and potentially fatal defect with which some babies are born. Baltimore's Dr. Al fred Blalock opened...
...central concentration of Japanese industry is in Brazil, to which sizable numbers of Japanese farmers have been emigrating since 1908, notably to Sao Paulo. The Japanese in Brazil control 67 firms ranging into insurance, banking, cement, glass and machinery. The Japanese-run Ishikawajima shipyard is working on its seventh vessel, and the new Usiminas steel plant, backed by a consortium of 14 Japanese companies, will pour 500,000 tons of pig iron this year. In Peru the Japanese have become leaders in the booming fish-meal industry, are also building a railroad in the backlands. In Honduras, Japan...
...such archaeological dive, says Bass, concentrated on a Bronze Age wreck found by sponge fishermen in 90 ft. of water near the Turkish coast, off Cape Gelidonya. With the same finicky techniques that archaeologists use on land, the water-borne scientists photographed the ancient vessel from above by swimming over it with underwater cameras-a preliminary process already reported in the National Geographic. They marked the crust of lime that covered the remains and carefully chiseled it into chunks that were lifted 3 to the surface by inflated plastic balloons. Bit by bit the wreck was moved ashore and reassembled...
