Shuttling Gas. Unlike typical internal combustion engines, the Stirling engine is powered by heat from an external source. In the Ford-Philips design (see diagram), hydrogen gas is heated by a burner, which can run on virtually any kind of fuel. The sealed-in hydrogen then expands, enters one cylinder and pushes a sliding piston. As the piston moves, it forces gas out of the other end of the cylinder; the emerging gas is cooled and then moves toward an adjacent cylinder where heat is applied once more and the process is repeated. As the gas shuttles between interconnected cylinders...
...inserted into the body to provide microscopic views of the internal organs and processes, and can serve as a long lens for a camera. It has proved invaluable for determining some of the reasons for female infertility. Introduced through the vagina of a patient under a local anesthetic (see diagram), the culdoscope gives doctors a sperm's-eye view of the female reproductive system, and has enabled them to discover several previously unknown defects that can prevent conception and pregnancy...
...contained a message that was frighteningly clear. Unless city officials paid the letter writer $1 million and assured him safe passage out of the country, he would set off an H-bomb in the middle of town. To make matters worse, the note was accompanied by a credible-looking diagram of a thermonuclear weapon. Consulted by city officials, experts at the Atomic Energy Commission refused to say for certain that the would-be bomber was not fully capable of carrying out his threat...
...door and ordered the 20 or so bank employees and six customers to lie face down. Patty Hearst stood 40 feet away, toward the center of the bank lobby-and carefully centered before the cameras-while Camilla Hall positioned herself at the far end of the bank (see diagram). All three covered the victims with their carbines while Perry and Soltysik took the keys from the tellers, unlocked the cash drawers and scooped...
Some observers nonetheless believe that there will be too much hardware in the sky (see diagram). Not many more than 22,000 businesses are now in the market for private telephone lines. And the three major commercial television networks have shown little enthusiasm to date for using domestic satellites. Since sports and news events originate in many areas, the networks prefer to rely on existing facilities rather than to build expensive new ones to beam the programs to satellites...
