Abstract

366,943. Gramophones. HEASMAN, H. J., 5A, Ferndale Road, Leytonstone, London. Nov. 4, 1930, No. 30484/31. Divided on 366,566. [Class 40 (ii).] A synchronous electric gramophone motor has pairs of permanent magnets b incorporated in the turntable a to form the motor rotor. In the form shown, the rotor spindle a3 is mounted in ball bearings c, c1 in the stator which is of the imbricated-pole type. Specification 366,566, [Group XXXV], is referred to.
