Senior member of the research team which gave this encouraging news to the Chicago Society of Internal Medicine and the Chicago Heart Association was Physiologist Andrew C. Ivy, vice president of the University of Illinois. Under his general direction, an astonishingly simple machine called the "flicker photometer" was perfected by Dr. Louis Richard Krasno, an assistant professor at the university...
...cylinder. In one side of the cylinder a window is cut to show a flashing light like a miniature lighthouse. The patient looks at the light through opalescent glass. If his retina and brain are getting a normal supply of blood and oxygen, the normal subject should see the flicker effect when the cylinder revolves as fast as 45 times a second. But if the eye's arteries are narrowed, the oxygen-starved retina loses sensitivity: the patient sees a steady light until the cylinder is slowed down- sometimes to only 30 turns a second...
...check the result, a tablet of nitroglycerine is dissolved under the patient's tongue. The drug enlarges his constricted arteries and allows a potential victim of heart disease to make a better score on the flicker photometer test. When the drug wears off, the retina again loses sensitivity...
Degradation. Both RCA and CBS are highly skilled at pointing out faults in the other company's system. First, says RCA, the CBS pictures are "degraded." This means that CBS, to increase the number of pictures per second and thereby avoid flicker, has had to reduce the number of scanned lines in each picture from 525 to 405. Thus, the "definition" is reduced and the grain of the picture is made coarser, like a newspaper cut compared to an illustration in a slick-paper magazine...
...process of squeezing assorted stool pigeons until they quacked like ducks, the Spanish cops rounded up five train robbers, the pants (Congressman Richards' still had a rabbit's foot in one pocket). Congressman Keogh's wallet and $3,800. They announced, not without a flicker of national pride, that the theft had been accomplished at the town of Las Casetas with a fishing pole. The Congressmen accepted their belongings gratefully. At week's end the Generalissimo received the visitors with the air of a man who runs in train robbers on time...
