...Commandos slip or bash their way inside the steel arc of Rundstedt's defenses to feel out German techniques. But old Rundstedt can tell himself that it has been an even trade. By their raiding, the British have had to give away their own techniques: how they carry tanks on barges, what kind of weapons they favor, what proportion of artillery they use. And the British can be sure that the Germans are profiting by what they learn...
...five years Londoners have watched the cement-arc slowly growing across the river (see cut). The finished job, 80 ft. wide, with five 240-ft. spans in gleaming Portland stone, looked so fresh and handsome against their war-and weather-battered city that it seemed, like a lorgnette on a charwoman, uncomfortably elegant. The bridge's designer, Sir Giles Gilbert Scott, sharing the public view, wistfully observed: "The chief feature is the underside...
...thin-lipped Junker von Bock, who has squandered men to win and lose some of Nazi Germany's greatest battles,* poured military dispatches that told him his foe was all but whipped in the northern Caucasus, that Timoshenko's main strength was apparently concentrated in a vast arc before Stalingrad, that German positions along the Don at Voronezh were safe for the moment. Bock might be on the threshold of an even greater victory. He could look with satisfaction on what his Panzers, shock troops, snub-nosed caterpillar guns and rank-on-rank of efficient infantrymen had achieved...
...Magnesium arc-welding-and perhaps the flying wing-will remain monopolies of the U.S. and its allies. Reason: arc-welding magnesium requires helium, which is found in useful quantities only...
Until last week, arc-welding magnesium was almost as impossible as welding paper, and for the same reason: this most inflammable metal* would ignite from the heat of the welder's electric arc just as it does in magnesium incendiary bombs. But after two years of research, engineers of Northrop Aircraft Inc. discovered that magnesium can safely be arc-welded if the hot metal is blanketed with helium to exclude atmospheric oxygen. The helium also cools the molten metal, acts as a metal-cleaning flux...
