Abstract

799,794. Transformers. CARDEN, Sir J. C. Nov. 9, 1956 [Nov. 29, 1955], No. 34170/55. Class 38 (2). [Also in Group XXXVIII] Electric leads 12, 13 supplying motors 3 mounted on a gramophone turntable 1 (see Group XXXVIII) are coupled by a transformer having a fixed primary 10 wound round the top of a pillar 2 and surrounded, with a small air gap to permit free rotation, by a secondary, 11 mounted on the turntable ; to ensure a 1 : 1 voltage ratio in spite of the air gap, the winding 11 may have more turns than the winding 10.
