Filed: 1929-08-03
Abstract: 336,699. Selenophon Licht-u.nd Tonbildges. July 4, 1929, [Convention date]. Sound recording and reproducing apparatus associated with kinematographs.-Special noises apart from the talking or musical accompaniment of a picture film are produced by stage machines actuated under the control of a record which is uniformly blackened or transparent except at those parts where it is required to effect a special sound and which may be positioned between the edge and the sprocket holes of the film. Different notes, each of a single frequency, are recorded on the special record and, in reproduction, these act on a light-sensitive cell and a set of electromagnetic vibrators arranged in series and tuned to be separately operated by the passage of the different notes on the film and thereby operates a corresponding stage machine to produce noises such as thunder, wind effect, dropping of a steam hammer, detonation of a shot, &c. The vibrator may comprise electromagnetically - operated tongues, the responsive one of which completes a circuit through a mercury contact to operate the corresponding noise machine. To ensure that these vibrators operate correctly at different speeds of film reproduction, the tongues extend over a conical roller which is controlled automatically by a tachometer, centrifugal pendulum, &c., connected with the reproducing machine.
