IPC: G11B7/00
Filed: 1936-11-19
Abstract: 477,727. Optical sound-reproducing apparatus. KOLB, O. K. Nov. 19, 1936, No. 31707. Addition to 462,195. [Class 40 (ii)] [Also in Group XXXIX] Relates to sound-film systems for the reproduction alternatively from films of the non- directional normal " or " asymmetric " types or of the stereophonic type and consists in the provision of electrical circuit changing elements operable at will to adapt the photoelectric reproducing equipment to operate with any one of these three types of film. As shown in the Figure, the light beam after passing through the film 10 is divided by the optical system 30 into two pencils which fall one on each of the twin cathodes 41, 42 of the photo-cell 40. These cathodes are connected individually to the switch arms S1, S2 of a switch S, the arm S1 co-operating with contacts S5, S9 and S13 whilst arm S2 co-operates with contacts S6, S10 and S14. Two other switch arms S3, S4 are also provided co-operating with contacts S7, S11, S15 and S8, S12, S16 respectively, these switch arms being connected as shown to the two amplifying channels 51, 52 which, in turn, are connected to the sound projector systems 61, 62. When it is desired to reproduce a " normal" film, the switch S is set so that its arms cooperate with the contacts S5, S6, S7 and S8 the cathodes 41, 42 thus operating in parallel upon the inputs of the amplifying systems and the sound emitted by the projectors is in phase. In order to reproduce an "asymmetric " film, the switch arms are moved on to the contacts S9, S10, S11, S12 in which position the cathodes are connected to the push-pull transformer 70, the output of which is fed in parallel to the amplifying systems and again the sound projectors emit sounds which are coincident in phase. Finally, when it is desired to reproduce a " stereophonic " film, the switch arms are moved into engagement with the contacts S13, S14, S15 and S16, in which position, one cathode 41 is connected through the amplifying channel 51 to one of the sound projectors 61 lying to one side of the projection screen whilst the other cathode 42 is connected through the other amplifying system 52 to the other projector 62 lying on the opposed side of the projection screen. According to a modified arrangement, Fig. 2 (not shown), the switching device for modifying the circuit conditions is connected in the output circuit of the amplifying systems. If desired, the twin-cathode cells may be replaced by selenium or cuprous oxide cells.
