Show Late Picture Invention The substitution of paper rolls for celluloid films in moving-picture moving-picture machines is made possible pos-sible by the new "cold" light discovered by the French engineer engi-neer Dussaud, which is described tq the Academy of Science by-Professor by-Professor Branley. It is obtained obtain-ed by automatic separation of heat rays from luminous rays, which occur together in all sources of light hitherto known to science. M. Dussaud has been working on this problem for many years. The light obtained by the method meth-od is so intense that it is possible possi-ble to throw images from newspaper news-paper illustrations, picture postcards post-cards and photographic prints on a screen, even in a lighted room, U dearly and sharply as if they Wire glass lantern slides. |
