...Cloud" and resuscitates the blues poetry of Sam Cooke, Otis Red Dog Herskovitz. The Lovin' Spoonful "jump-cut" provocatively among narratives, and interrogatives; such lively imagination no-one demanded or would have appreciated a few years ago. One can see Dylan's influence sifted down to the bottom of the heap when a dullard like P.F. Sloane ("Eve of Destruction") manages a rime as interest...
...runs made for this year, the top-to-bottom exchange index showed almost exactly the same percentage changes as the selective Dow-Jones. But its point spread was smaller and the market decline did not seem so spectacular. It should be recognized, however, that neither will a market surge...
...Question. Under such conditions, how could an engine in orbit be restarted for a flight to the moon? Engineers speculated that if an Apollo vehicle were accelerated slightly, the inertia of the liquid hydrogen would force it toward the bottom of the tank. To provide that acceleration, they installed controllable, backward-pointing vents at the top of the SIV B's fuel tanks. They hoped that the gases gradually produced by the evaporating liquid fuel and oxidizer could be released into space to provide slight thrust and acceleration...
...engineers installed television cameras inside the SIV B's hydrogen fuel tank. All through the acceleration of blastoff, and while the Saturn I first stage was pushing the SIV B aloft, the TV screens at the Houston control center showed the liquid hydrogen settled and calm on the bottom of the tank, its surface barely rippling. After the first stage had dropped away and the SIV B's engine was fired to insert it into orbit, the level of the liquid hydrogen could be seen dropping rapidly as fuel was consumed in the combustion chamber...
With its tank vents still spewing tiny jets of gas, the slowly accelerating SIV B was then put through a simulated engine restart. Valves at the bottom of the tank opened, allowing liquid hydrogen to flow into the combustion chamber. Clearly visible on TV, the dwindling fuel hugged the bottom of the tank, its surface calm...
