...burned in a roughly spherical combustion chamber, and turns into hot, high-pressure gas. To keep the gas from expanding wastefully in all directions as it leaves the nozzle, it is channeled into a tail cone where its pressure is efficiently converted into thrust as it expands (see diagram). The cone should be long enough to reduce the pressure of the gas to that of the surrounding atmosphere. Thus rockets intended to work at very high altitudes must have extra-long tail cones...
...sketch of his own recent music (see cut). The knobs in the sketch stand for notes, suggest that Stravinsky wants all notes to be heard and considers them more important than do other serial composers, who care more about dynamics and instrumental colors; the leanness of the diagram suggests thinner, simpler orchestration. Says he: "Those younger composers who already claim to have gone beyond, to have exhausted serialism are, I think, making a great mistake...
...into a spherical reaction chamber, the compact mass becomes critical. A nuclear chain reaction starts, and heats the solution. Before the reaction goes too far, the solution is sucked away by pumps and forced through a heat exchanger, where it heats ordinary water to produce high-pressure steam (see diagram), which in turn can be harnessed to an electric generator. Since the fuel is liquid, it can be renewed by periodically passing it through a special purifier...
Instead of cylinders and pistons, the Wankel engine has a single combustion chamber shaped like a fat-waisted figure eight (see diagram). Inside, it is a three-cornered rotor with curved sides. A shaft passes through the rotor and makes it move on an eccentric orbit by means of two gears. All three corners of the triangle stay in contact with the wall of the chamber at all times. To make the contacts gaslight, each corner is tipped with an inset metal strip that, as the drive shaft revolves, is pushed tight against the cavity's inner walls...
...steel spring is a single-strand steel wire for stiffening. As in the Syracuse housewife's case, polyethylene tubing is slipped over the steel spring. But in her case, the doctors did not go beyond the aorta. Now they go around the aorta's arch (see diagram) to its end at the aortic valve-the blood's exit from the left ventricle...
