...thermoelectric sextant, using infra-red rays, invented by Paul Humphrey Macneil. The infra-red rays are in the long-wave end of the electromagnetic spectrum. They are really heat waves, capable of penetrating clouds. The Macneil Sextant has a curved reflector that collects and potently focuses infra-red rays on a thermocouple, two pieces of metal which when heated even one-millionth of 1° give off a tiny flow of electricity. This flow is enormously amplified, measured by a galvanometer. When the curved reflector is pointed directly at the sun, the flow of electricity is greatest and the navigator...
...impressionable is the instrument that it records even the heatwaves of another ship, a smokestack, an airplane, many miles away; the heat of a man's face a mile away. It not only registers heat waves, but differences of temperature in itself. At night, or in a fog. the electric eye sweeps the horizon. When it encounters an iceberg it loses heat. This loss of heat is recorded, the position of the iceberg determined. Now Macneil is trying to make it record even the infra-red rays from the stars, to chart a ship's position at night...
...Cincinnati, Duke Poao Kahana-moku of Hawaii, who has been on every U. S. Olympic swimming team since 1912, arrived by airplane for the final trials. Two men qualified in each of the 100-metre free style heats. In his heat Kahanamoku finished third, pulled himself wearily out of the pool, shook the water out of ears, looked gloomily at his muscular legs as if dissatisfied with the black sunburn which he has spent 42 pleasant years acquiring. Said he about his legs: "They were O. K. for 75 metres-after that it was just too bad." Not greatly surprised...
Next day Maiola Kalili finished third in the final heat, behind Ray Thompson of Annapolis and Al Schwartz of the Illinois athletic Club, who won. Clarence ("Buster") Crabbe won the 1,500-metre free style race; but spies from the Japanese Olympic team, who sat peering at the meet and scribbling in note books, wrote a long description about a freckled 14-year-old Floridian, Ralph Flanagan, who finished a close second. Crabbe won the 400-metre free style two days later, in better time than the Olympic record...
...again," said he, "but I don't know what Eastman will do the next time." In the final track & field trials at Palo Alto, Calif, last week. Carr had his chance to find out what Eastman would do at 400 metres. Carr won a fast heat. Eastman won a slow one. In the final, Carr ran from an outside position. He slipped in behind Eastman at the turn, sprinted down the straightaway, won by six clear feet...
