Godwin and Walker obtain their very bright, very brief flash by discharging 38,000 volts through a vacuum tube filled with mercury vapor at one-twentieth of atmospheric pressure. The voltage source is an X-ray apparatus and the current is stored in a 20-unit Leyden jar condenser...
...duration of the flash can be timed approximately by noting the amount of blur (equal to the distance traveled during exposure) on the bullet. If the bullet travels at 1,000 ft. per sec. and the blur amounts to one-thousandth of a foot, the time interval is one-millionth of a second, fastest exposure ever accomplished...
...their flash, they place a spark gap close to the gun's muzzle so that the bullet passes just below the electrodes. The hot gases and burning powder which follow the bullet enable the spark to jump the gap, completing the circuit and discharging the voltage through the vacuum tube. Only one picture is taken at each shot. But by moving the spark gap nearer to or farther from the gun's muzzle, the bullet can be snapped at various points of its trajectory...
...typical star who has been developed under Ulen's tutelage has been the work-horse type, not the natural, born swimming flash. He brought Hutter's 100-yard time down from 57 seconds in his Freshman year to a brilliant, consistent 52 seconds in the Junior and Senior years. He converted Dario Berizzi from a mediocre distance man to a crack butterfly breastroker. He helped Don Barker wend his way from the ranks of the House tankmen to eventually become a 23 second...
