...economists that sales of such smaller-ticket items as appliances and television sets are in line for further declines as the ripples spread throughout the economy. But the first to feel the effects of a prolonged slump would be steel, rubber and glassmakers, whose products go into automobiles (see diagram...
Small's invention, called the mandibular staple, is a lightweight titanium bar with two long, threaded pins and up to seven shorter ones (see diagram). It is attached to the dense bone on the underside of the jaw where its short pins help hold it in place. The long pins pass through the mandible and protrude through the gum into the mouth. There they serve as abutments to winch a dental bridge can be fastened...
...September. At some point, Nixon's physicians say, a part of that clot, or possibly a new one, broke loose. The embolus was carried away in the bloodstream, like debris in a fast-flowing river, through the iliac vein and the inferior vena cava into the heart (see diagram...
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...
