Important Invention for Motion Pictures Urbana, Li., July 3i.
Prof. Joseph T. Tykociner of the University of Illinois, after 10 years' work, has constructed a machine which not only photographs the usual moving picture as seen on the screen, but at the same time and on the same film photographs scund, it was announced by the University to-day. So far have the experiments gone that the ring of a ell, the slam of a door, an} the human voice are produced in the laboratory tests, it was stated.
With the patenting of this machine, the university has obtained the second of its patents on apparatus fundamental in the art of talking motion pictures. Six months ago that institution announced, that another of its staff, Prof. Jakob Kunz, had perfected a selenium ce]l which, unlike its predecessors, it was stated, did not show any fatigue through use. This cell is used for photographing sounds.—Reuter.
