There were three critical solid-fuel rocketry breakthroughs: 1) development at Caltech and Aerojet-General Corp. of a new type of solid fuel that will last a year or more inside underground launching cylinders without cracking; 2) development at Massachusetts Institute of Technology of a new-type guidance gyro that can be kept running continuously inside the underground slots for as long as two to three years; 3) successful testing by Thiokol Chemical Corp. of the biggest solid-fuel rocket engine ever built, with more than enough thrust to meet ICBM requirements...
...Closet. The Instrumentation Laboratory's most important technological advance in building the jam-proof navigational system was the development of the Hermetic Integrating Gyro (HIG), a 3-in. long package containing a gyroscope spinning at 12,000 r.p.m. in an inner cylinder pivoted on virtually friction-free bearings and floated in a heavy liquid. Three HIGs -one to "memorize" each coordinate of a point'on an imaginary star line at take-off -and three accelerometers (to measure change of speed in each direction) are fixed to a gimbals-mounted, free-swinging platform unaffected by changes in the plane...
Died. Hannibal Choate Ford, 77, noted engineer-inventor, who helped the late Elmer Sperry perfect the Gyro-Compass (1911), during and after World War I developed the world's first mechanical control-computer for naval gunfire; of arteriosclerosis; in Kings Point...
British carriers are to be equipped with big curved mirrors that face aft from the end of the landing runway (see diagram). The mirror is mounted like the mirror of a dressing table, so that a gyro stabilizer can keep it at the proper angle no matter how much the carrier may be pitching. On each side of it are horizontal rows of colored lights. Strong white lights shine into it from near the carrier's stern...
...Some ten miles to the south he spotted a towering thunderhead. Rain poured from its base, and lightning played around the high-riding, anvil-headed cloud. Sure that it would contain powerful updrafts, Comte headed for it. As he maneuvered under its base, he switched on his electrically driven gyro-horizon...
