Abstract
709,385. Kinematograph apparatus. STEATITMAGNESIA AKT.-GES. April 29, 1952 [Aug. 7, 1949], No. 10755/52. Class 97(1) In a projector, particularly for narrow films, the main electrical elements are combined into a single removable unit. As shown, a transformer has windings 2 carried on laminations 3 which support a board 8 carrying a voltage selector 9 and fuse 10. A board 11 on a perpendicular face of the laminations carries a motor regulating resistance 14, a motor switch and the current supply plug 12. The laminations are secured by bolts 4 in hexagon nuts 5 secured to the base 7 by bolts 6. Two of the bolts 4 extend upwards and support the motor 16 on springs 15.
