"Movies over the air Is the next great achievement of radio engineers I Moving pictures will flash across the continent at the dizzy speed of 1SG.300 miles a second, the speed of light, And they will appear on a screen in natural colors in the homes of millions of radio users. The introduction of the radio-vision receiving set heralds a new era for radio science! An unpretentious cabinet converts radio waves Into light and shadows. This remarkable transformation is accomplished by means of a lamp contained con-tained In the box. This lamp lights and extinguishes a half million times a second. A disk or ring, containing small lenses around Its outer edge, is contained con-tained in this box. The purpose of this disk is to chop up the light and shadows Into lines and adjacent successive suc-cessive Unes. Motor in Set. A small electric motor, likewise contained con-tained in this box, revolves the lens-carrying lens-carrying disk. A white screen, which may be held in a small picture frame, is placed on the wall receiving the motion picture. pic-ture. The light from the lamp inside of this box, or small cabinet, is reflected onto the miniature screen through a slit arrangement by means of a prism reflector, placed on top of the box. In this way the receptionist can switch from hearing his favorite orchestra or-chestra to watching it play. Or he may hear it and watch it at the same time. C. Francis Jenkins is the inventor of the lamp which performs the wonderful won-derful task of transforming radio waves to light and shadows by lighting light-ing and extinguishing itself a half million mil-lion times a second. "Modern Aladdin Lamp." This marvelous globe has earned for itself the name of the "modern Aladdin lamp." The Jenkins radio-vision lamp operates" oper-ates" on the Wheatstone bridge principle, prin-ciple, whereby a little change in electric elec-tric voltage gives a large change in light flux or flow. This lamp bears a relation similar to the function performed by a sensitive sen-sitive mineral used at the radio-vision transmitting station. 1 This sensitive mineral potassium, for instance converts the motion picture pic-ture at the sending station into electrical elec-trical values for transmission on a radio carrier wave. The Jenkins radio-vision lamp reverses re-verses this process, changing the electric elec-tric current back to picture values. Once motion pictures by radio are introduced into thousands of homes, this lamp will be as commonplace as the electric light bulb or radio vacuum tube. |
