...These are the ultra violet rays, as it were, of the painter's spectrum, and the artist who, like Mr. Chandor, is not blind to them presents a genuine and sincere portrait rather than a mere likeness...
...Rentschler constructed a photo-electric cell with one pole made of uranium. Uranium is sensitive only to the ultraviolet rays of the spectrum. They charge it electrically. Hence when the Rentschler uranium bulb is exposed to an ultraviolet ray source an electric charge is created in proportion to the ray's intensity. This charge is accumulated in a condenser until a given potential is set up. Then the condenser discharges and, in the Rentschler meter, makes an argon tube give out a bluish flash and simultaneously causes a pencil to mark the occurrence on a chart. The time between...
...Alen's plans for the new Chrysler Building, to be world's highest (68 stories), now under construction in midtown Manhattan. Everywhere apparent was the tendency toward simplification of form, and the invention of new forms rather than reliance on archaeology. Colorists now apply a vivid spectrum to polychrome decoration and colored tiles. Aviation architecture proved a feature instead of a novelty. The New York Times displayed a plaster model of Commander Richard Evelyn Byrd's winter headquarters in Antarctica, with four T-shaped landing and take-off platforms, three skeleton wireless masts, a group of gabled...

...newsgathering organization with correspondents in all chief U. S. cities to collect and write news items suitable for radio broadcasting, with a nationwide clientele of radio stations (one in each city and two or more in the larger centres), with 20 wavelengths in the short-wave spectrum for its own use, with a network of teletypewriter lines so that its stories would be automatically transmitted ready for use in broadcasting rooms, and with an arrangement for selling radio broadcasting for the stations on a 15 per cent commission-such was the organization visualized last week when a National Radio Press...
