Abstract

443,110. Combined sound-reproducing and kinematograph apparatus. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Aug. 20, 1934, No. 23980. Convention date, Aug. 19, 1933. [Class 40 (ii)] [See also Group XX] A self-contained equipment for projecting pictures and reproducing sound from a film has the double-walled casing 1 divided into two compartments 2, 3, the fan 5 and the picture projecting lamp 6 and its resistance 7 being accommodated in compartment 2 whilst the other parts of the equipment are located in compartment 3. Air drawn in by the fan flows around the compartment 3 which may be provided with cooling fins, cools the condenser 9 and passes through opening 15 into compartment 2 where it flows round lamp 6 and resistance 7 and leaves by opening 16. The parts of the double walls of compartment 2 which do not serve as air way may be filled with sound and heat insulating material.
