That first or second evening at your "reception" center (Camp Devens, perhaps) is critical, and may hound you the rest of your days if you don't fly the beam. Cramming is out, but it wouldn't hurt to hit your I.Q. test hard, aiming for at least 110 out of 161, while a good mark on your mechanical quiz will pave a smoother road to the job of your choice...
...Reader Johnson, Author Fuller and TIME'S reviewer are all on the beam. James Lawrence said the words. Captain Perry's flagship at Erie was named the Lawrence, and so it was fitting that he should have a battle flag with the motto...
Last week demonstrations by Floyd Ramsdell of Worcester Film Corp. brought nearer the day of movies in depth and color, when the screen will seem to be a stage of unlimited scope. Persistent, inventive Floyd Ramsdell does not use a double camera or double projector, relies instead on a "beam splitter." This mounts two lenses on a single camera, prints the two pictures-one from each lens-side by side in each frame of a motion film. The projector may thus be any standard make but is also fitted with a beam splitter which sets the two pictures almost over...
...result is a blur to the naked eye. To separate the two pictures so that each eye sees only the image meant for it, Polaroid sheets must be used in the beam splitter and also in glasses worn by the audience. Polaroid is a thin plastic containing myriads of tiny, imbedded, needle-like crystals of iodo-sulfate of quinine, all parallel. When a beam of light strikes the sheet all light waves that are vibrating in the plane of the crystals pass through, all others are stopped. Thus the two beams of light from the projector are filtered so that...
Polaroid Corp. has an even more erudite scheme which will make use of the full standard-screen size and shape, will require no accessory beam splitter or double projector. In the vectograph, a Polaroid patent, the two pictures, one for each eye, are printed over each other on the same photographic film or paper. Incorporated with them is the polarizing material. When viewed with Polaroid glasses the picture is fully three-dimensional in ordinary light. When thrown on a screen from an ordinary projector the pictures are automatically polarized by the film, thus need only the viewing glasses...
