...Voice does not beam broadcasts to Japan-where the occupation authorities are doing their own effective information job-or to Indo-China, Burma and India (Radio Moscow diligently broadcasts to these countries). Recently the Voice has started successful broadcasts to the young Indonesian republic, which has proved inexhaustibly curious about...
...electronic instrument-landing methods are already in practical use. One, ILS (InstrumentLanding System), projects into the sky a narrow beam of high-frequency radio waves. Slanting at a gentle angle, the beam forms a "glide path" which an airplane equipped with the proper instruments can follow down through...
George can probably do it. Experimentally at least, the automatic pilot has been hitched to both ILS and GCA. When following the ILS glide path, George accepts electronic signals from the ground and nudges the airplane's controls to keep it in the center of the beam. The pilot is free to watch the plane's flying instruments and to monitor the whole operation...
...tube-which eventually may be used in other color systems-comes in two types. The first has a single electron "gun" in the neck of the tube, which shoots a single beam of electrons-producing three colors: red, blue and green-onto the face of the tube. The millions of electrons are spun in front of a mask containing 117,000 minute holes, or one for every three dots on the viewing screen itself. The holes in the mask expose the incoming electrons to each of the color dots in turn, thus making a picture which approximates the color...
...second type of color tube works in a similar way, except that each of the three colors is produced by its own special "gun." Whenever a beam is uncovered by one of the infinitesimal holes in the mask, the right color dot appears at the right point on the screen...
