Soaring through space nearly a million miles from the earth, Mariner 5 responded smartly last week to signals radioed from Pasadena's Jet Propulsion Laboratory, thereby ensuring that its Oct. 19 date with Venus would be as intimate as intended. The spacecraft pitched, rolled and fired its rocket engine for 17.66 seconds, giving the spacecraft a 36-m.p.h. boost and arcing into a trajectory that should carry it past Venus at a distance of only 1,250 miles...
...revolutionary rifle is the brainchild of Belgian Chemical Engineer Jules van Langenhoven, a gun fancier who began to experiment with new propellants in 1951 in an effort to reduce the weight of cartridges. By 1961, Van Langenhoven had produced a derivative of nitrocellulose that could be ignited by a jet of hot air and that actually eliminated the need for a cartridge. Daisy President Cass Hough got wind of Van Langenhoven's experiments and flew over to Paris for a demonstration in an instrumented firing range near the Champs Elysées. Using a modified air rifle and pellets...
...rear of a slug or missile. When the trigger of a V-L rifle is pulled, a powerful spring drives a cocked plunger into a cylinder, compressing and heating the trapped air to about 2,000° F. Escaping into the firing chamber through a valve, a jet of heated air strikes and ignites the propellant, which pushes the missile through the barrel (see diagram). Because the heated air helps the propellant to oxidize completely, there are no unburned traces left to foul the barrel. V-L test rifles have been fired up to 50,000 times without cleaning...
...about 60 U.S. newspapers, Society Columnist Aileen Mehle, better known as Suzy, was as sad as a songbird with laryngitis. For two months after the demise of the World Journal Tribune, Suzy had no journalistic tree to trill from in New York, her home town and headquarters of the jet-setters whose fads and foibles she chronicles with re freshing irreverence. Last week Suzy was back home, regaling readers of the New York Daily News (circ. 2,100,000) with her tart tales. Items...
...executive jet, one of the brightest gleams in the eye of the aircraft industry, is having a bit of trouble. Of the 25,000 corporate-owned planes now flying, only about 350 are jets. And with the past year's tight money, lower profits and suspension of the investment tax credit, many a businessman concluded that a private jet was an extra that his company could do without...
