The Fultograph

Used for N ovel Purpose THE Fultograph picture transmission system is to be put to a novel use at the Slough Radio Research Sta tion for the purpose of recvrding at mospheries. By arrangement with the B.B.C. special Fultograph transmissions will be made from Daventry after the normal experimental periods, and these will be. picked up at recording stations in various parts of Burope. The transmissions will not take the form of pictures; instead there will be sent out 2 series of straight lines, both horizontal and vertical, forming a grid or network. When the atmospheriec occurs deformations of the straight lines will take place to an extent depending upon the intensity of the interference. It is hoped by this means that it may be possible to make records giving the most valuable data for research into the intensity, duration and origin of individual atmospherics. Since the drums of all receiving apparatus, wherever situated, are synchronised, it will be possible-by comparing the results obtained in different places to determine the range at:which an individual atmospheric can cause interference and the intensity of this interference in different lo¢alities.
