United States Television Mfg. Corp. announced a new 15-m. receiving tube (with a flat instead of the normally convex face) which will increase the size of pictures on its sets some 10-20% at no boost in price. And Radio Corp. of America told of a much greater improvement to come (probably by year's end). It has developed a 16-in. steel cathode-ray tube (the basic part of a television set) which can be mass-produced to replace glass tubes now in use, thus lowering the costs of some sets...
...curve in London's Thames Embankment, midway between the Houses of Parliament and the Tower, stands a massive granite pile, boldly convex. Its 16 grey Ionic columns give an impression of opulent security worthy of a king's exchequer. This is Unilever House. In front stands a statue of Queen Victoria, symbol of Empire. The juxtaposition is apt. For Unilever House is an empire within the Empire, the greatest industrial realm in the British world...

...scientific design could do for acoustics. He went into huddles with NBC Chief Engineer O. B. Hanson. Early in February, NBC's big studio was closed off. Workmen built a slanting roof over the stage, faced the back wall with a marcelled pattern of half columns (technical name: convex diffusers), turned the side walls into a checkerboard of curved sections-all done to encourage resonance...
...cameras. Essential part is a concave spherical mirror which gathers starlight, focuses it on a photographic plate. But mirrors hitherto could focus light from but a small section of sky on the plate without fuzzing and distortion. In the Schmidt camera, however, the light rays pass through a concave-convex lens which aims them at the mirror at such angles that they are reflected upon the plate in sharp focus (see diagram). Photographs of distant, dim nebulae formerly required exposures of 50 hours-five hours a night for ten nights. Now they can be made in a single night...
