General Electric Electronic tubes will lift the fog from sky, sea, and land! Fog coming in! Ships crawl. Planes are grounded. Cars hug the side of the road. You can't see for the "pea soup." But General Electric is "lifting" the fog! Tomorrow, amazing electronic devices will tell the ship captain the position of reefs ... permit the pilot to land blind ... warn the locomotive engineer of danger on fog-drenched tracks. Ship and plane and train will ride as safely in fog as in sunlight! The exact nature of these mirac ulous inventions must remain a war secret. But General Electric research has developed a thousand other electronic devices that add to your health and comfort! Electronic tubes, basically the same as the ones in your General Electric radio, can distinguish 2,000,000 shades of color. An electronically controlled welder stitches together metal parts of war planes as easily as your sewing ma chine stitches cloth. By electronics, you can study the stresses in an airplane wing during a power dive, or make photographs with the ex posure automatically determined. Production of General Electric electronic equipment is limited to day to businesses engaged in war activity. If electronics can be ap plied in your plant, write General Electric- Radio, Television, and Electronics Dept.,Schenectady,N.Y. GENERAL*,, ELE. . Leader in radio, television, and Every General Electric radio is an electronic instrument This is a General Electric electronic radio tube, similar to those used in all G-E radio sets. The miraculous electronic tubes that will "see" through fog tomorrow will be essentially of this kind.
