Abstract

313,986. Neale, J. March 19, 1928. Light-sensitive cells.- The light-sensitive surface 4, on to which light from a source 1 is reflected by a sound-actuated mirror diaphragm 2, comprises two semi-annular selenium cells arranged end to end or four cells in the form of two concentric rings. In either case the cells are arranged in the arms of a Wheatstone Bridge across which is connected a suitable sound reproducing instrument. The cells are preferably constructed as described in Specification 284,942.
