...small university in New York proved that buffaloes are not extinct, and the football team's first encounter was indicative of events to come. Following the team's first loss, the Varsity Club mysteriously caught on fire. And, as a result, the Harvard Band, which lost most of its scores in the blaze, was added to the New York Times' list of the Hundred Neediest Cases...
Solid-fuel rockets are the dream weapons of military rocketeers. They have no pumps or valves to go wrong and are always ready to fire. Their big trouble is that they are harder to control than liquid-fuel rockets, whose small combustion chambers, fed by flexible pipes, can be mounted on gimbals. When a liquid-fuel rocket takes off, it can switch its gas jet from side to side, correcting any tendency to veer off course. But solid-fuel rockets have no separate combustion chamber, only a nozzle to form the gases into a high-speed jet. Usually the nozzle...
Vacuum Extinguisher. If the power is to be cut off entirely, it can be done by extinguishing the rocket's fire. This is almost impossible at atmospheric pressure; if the flaming propellant is extinguished, it tends to relight. But in the vacuum of space all that is necessary is to blow off the rocket's nozzle. The vacuum outside strikes into the rocket's heart. The hot combustion gases are sucked away from the unburned fuel so quickly that they do not heat it to the kindling point. The rocket's fire goes out instantly...
Ordinary window glass is made by drawing a wide ribbon of glass vertically from a reservoir of syrupy melted glass. It cools in the air and has a brilliant "fire finish." But the process of drawing produces stresses that make flaws and irregularities. To make the glass smooth enough for mirrors, auto windshields and store windows, manufacturers are forced to an elaborate process of grinding and polishing glass sheets on both surfaces. The plate glass made in this way is expensive, and its surface lacks fire brilliance...
...floated in a tank of molten metal (the metal or alloy used is a trade secret). As the ribbon moves to the far end of the tank, it is cooled by a controlled atmosphere and finally solidifies. The result is a sheet of glass that is mirror-flat and fire-bright...
