Abstract

436,495. Motors. MIHALY, D. VON, 3, Hildegardstrasse, Wilmersdorf, Berlin. March 20, 1935, No. 8702. Convention date, March 21, 1934. [Class 35] Motors with unwound iron armatures.-To obtain uniform speed, the electric motor driving sound-on-film recording or reproducing apparatus is of the phonic wheel type having a stationary internal part 5, and a rotary external part 6 carrying the armature winding 7. The fixed member 5 is keyed to a spindle 1 mounted adjustably at its lower end in a support 2 or in an elastic sleeve. The rotary armature 6 drives a hollow shaft 10 carrying the film sprocket. The armature winding is fed through stationary brushes 13, 14 and slip rings 11, 12. The external part of the motor is entirely closed to prevent interference with the photo-electric cell of the sound apparatus.
