...Hatlestad model has a conventional propeller, but in place of wings there are freely spinning horizontal rotors 14 in. long and 2 in. in diameter. The rotor is composed of two semicircular vanes on an axis-in cross section shaped like the letter S. As the plane moves forward, air pressure causes the rotor to revolve backward. That action, combined with the forward movement, produces low pressure on top of the rotor, increased pressure (lift) on the bottom. If the motor should quit the rotor continues to spin in descent, the lift force stretching the plane's course into...
...correct. Harvard must soon succumb to the rebirth of the cycling fad. Then will Dunster forfeit the grandeur of isolation, and then, too, will Jefferson and Mallinckrodt be near enough the Charles to permit Winthrop and Eliot to breakfast in leisure. Radcliffe and Harvard will take a Sunday afternoon spin on a "bicycle built for two," while the more ambitious undergraduate will in one short hour pedal to Wellesley. If Harvard is to be Anglicized, the process may as well as not be complete. The Master of Lowell has set a noble example: may all Harvard bravely follow his lead...
...Blue Bird towed to the end of the course, 40 yd. wide and nine miles long with the measured mile in the centre, the sand was still rough and strewn with shells. Sir Malcolm's left wrist, sprained on the gearshift in a 240-m.p.h. trial spin last fortnight, was still sore. A thin dangerous haze had not entirely disappeared when Sir Malcolm decided he could wait no longer...
...mile west of the airport, 800 ft. aloft, the big ship went into a spin, crashed into a grove of trees. Engineer, assistant, test-pilot, all were killed. To their graves they took the secret of the crash. Best guess: sudden shifting of the bags of lead ballast...
Extant is an old French print showing the future King Louis XIV playing when dauphin with his Yo-Yo-a child's top so made that when thrown from the hand it starts to spin as its string unwinds, then winds up the string on itself and returns to the hand. During the past two years a Yo-Yo craze has swept Europe. Among smart Parisians, Berliners and Londoners are hundreds of exalted Yo-Yo addicts, notably Edward of Wales. Just before Edouard Herriot fell as Premier of France, a Paris weekly pictured his frantic appeals to all sections...
