Last year Professor Ernst Alfred Hauser of Massachusetts Institute of Technology discovered a new kind of wrapping material -odorless, tasteless, impervious to fire and corrosion by acids-made from bentonite clay and called "Alsifilm" (TIME, Nov. 7). Alsifilm is already being used to replace mica (isinglass) in electric motor and generator insulation. Last week Professor Hauser looked forward to a time when Alsifilm would free the U. S. of dependence on foreign supplies of mica, now largely imported from India...

...Zworykin sender the image to be televised falls on a small sheet of mica covered with millions of microscopic dots of photosensitive cesium. Each tiny dot receives an electric charge according to the amount of light that falls on it. A beam of electrons shot from a cathode tube and controlled by rapidly oscillating magnetic fields weaves back & forth across the sheet of mica 6,000 times per second. The beam discharges the electropositive tension in the dots, and the changing pattern of this discharge modulates a current passing through the sheet. The modulated current, fed into a radio transmitter...
