...positive print is placed on a cylinder which revolves 100 times per minute and moves horizontally one inch per minute. A tiny beam of light, trained on the picture at a 45° angle, is reflected to a "light valve." Inside the valve is a shutter which opens and shuts 1,200 times per second. The reflected beam sends the lights & shadows of the picture through the shutter to a conventional photo-electric cell ("electric eye"). There the image is translated into electric impulses which flash over the wires-10,000 mi., if desired-to the receiving machine. The receiver...
...deflected until they collide squarely with a nucleus. Nevertheless their mass (about 1,800 times that of an electron) has been established within fairly precise limits. And last week three Columbia physicists announced the size of the neutron as slightly less than .0000000000001 (one ten-trillionth) of an inch...
...series of hoops & hurdles. Beryllium powder was placed in a glass tube containing the radioactive gas radon. Alpha particles from the radon knocked neutrons out of the beryllium. First hurdle was a metal ring which deflected part of the neutron beam toward a cylindrical detection chamber less than an inch across, a half-inch deep. The chamber's door was guarded by a paraffin screen from which the neutrons evicted protons. Having positive charges, the protons ripped through the chamber, freeing ions which were collected on an insulated electrode so that their flow could be amplified, detected, measured...
...remarry his divorced wife Helen. The Cabinet formally asked him to send Lupescu away. Lupescu herself, badly frightened, offered to leave Rumania, if that was all his enemies wanted. But Carol assured her confidently that things were not so bad as that. On that one point he was every inch a king: he decreed that indispensable Mile Lupescu must...
...Lamb remained Ghent's and Belgium's pride, lost only partial glory in 1816 when two panels were sold to Prussia. By the Treaty of Versailles these two were returned to Ghent. But last week there were only eleven in all. Gone was the 54-by-22-inch The Virtuous Judges (red and blue-cloaked riders backgrounded by crags and castles) and the grey John the Baptist painted on the other side. Because where once hung the panel in the Flemish galleries of the Berlin Museum there was tacked a placard reading, TAKEN FROM GERMANY BY THE VERSAILLES...
