...then postmarks and cancels 500 stamps a minute, double what a man can do. Next November the Post Office will get a 75-ft. long P-B mail sorter by which twelve operators each can sort 720 letters a minute-triple the manual rate. Each letter passes on a conveyor belt before the eyes of a postal worker, who pushes keys to direct it to one of 300 cubbyholes. Now P-B's scientists are tinkering with the ultimate in postal automation: a mechanical scanner to "read" the address and do the sorting automatically...
...Bomb Plan. During the war Behlen noticed that rubber conveyor rollers for mechanical corn huskers were unavailable. He devised a substitute from old auto tires-and in 1944 netted $40,000. The next year Nebraska was soaked by rain, and farmers needed dryers for their piled corn. Behlen designed long pipes that could be thrust into the corn, hooked up hot-air fans to blow through them. Farmers snapped up the simple dryer,* and such other Behlen inventions as auxiliary gears to make old tractors go faster...
...uphill fight. Some 30 years ago, U.S. humane societies were aghast to discover that a steer being led to slaughter was first stunned by a hammer blow-often ineffectively-then slashed across the throat and allowed to bleed to death. Hogs were shackled by a leg to overhead conveyor belts, jabbed in their jugular veins, sometimes dumped alive into scalding water. The societies pressured meat packers into joining a committee on humane slaughter that achieved some innovations, e.g., some packinghouses began using a captive bolt pistol, which fires a metal rod into the brain; George A. Hormel & Co. installed carbon...

...assembled by a nine-year-old, but it includes a booklet of diagramed directions that many a parent will be hard-pressed to decipher. Other toyland marvels include an electronic robot ($8.95) that picks up pieces of metal by remote control and drops them onto a motor-driven conveyor belt; an electronic teletyper ($16.95) that prints messages sent from another room or house; a Pan American clipper ($15.95) that automatically starts and stops its four engines separately, revs up its motors before scooting along the ground...
