Back home the cigarette makers continue to introduce new brands to cater to the capricious tastes of 70 million U.S. smokers, with big emphasis on filters. Liggett & Myers is testing a charcoal filter menthol brand called Devon, and Philip Morris is marketing a charcoal filter called Galaxy in Texas. Filter cigarettes now hold about 70% of the U.S. market, but the charcoal filters, which account for some 7% of sales, have had uneven success...
...king-size Pall Mall is still the fastest seller, closely followed by R. J. Reynolds' Winston. Unfiltered Camel and Lucky Strike, which vied for first place until the late 1950s, are steadily losing favor. In a comeback attempt, American is test-marketing Lucky Strikes with a tobacco-flavored filter, has sent out Luckies' veteran, quick-tongued radio auctioneer, "Speed" ("Sold American!") Riggs, to promote them in stores throughout the South...
Robb now had what amounted to an artificial membrane. Just as the lining of the lungs blocks out liquid blood but lets oxygen in and carbon dioxide out, Robb's membrane was able to filter through its gossamer skin the tiny dissolved bubbles of oxygen-rich air from water without drawing any of the liquid with it. Robb's membrane works best in a tank or stream of running water, where bubbles of oxygen are plentiful to draw on. Then the artificial membrane can operate as a gill does when it filters oxygen into a fish...
...engine tested in a 30-minute, 3,200-mile flight over the Pacific got its thrust by passing vaporized cesium metal through a hot tungsten filter. This action strips electrons from the cesium, speeds the positively charged ions out the rear of the engine. The great advantage of this process is that it requires remarkably little fuel-only one-tenth of that for a conventional chemical rocket. Even the smallest ion engine could keep a satellite on its right course for more than ten years by giving it gradual nudges. On a 300-day trip to Mars, a full-scale...
Often, esthetics enters usefulness by the back door. The late Dr. Peter Schlumbohm used the chemical principle of filtration to make the trim Chemex coffeemaker, then simply placed a disk of filter paper inside a circular housing to make a new kind of fan. Spun by a motor, the rippling paper edges cast air through the rim by centrifugal force. A ban vivant of the first order, Schlumbohm made a rapid, but esthetic, champagne cooler just because he felt bachelors should not be caught short when unexpectedly entertaining women...
