Abstract

1394291 Gramophone turntable CRAXFIELD INSTITUTE OF TECHNOLOGY 2 Feb 1973 [7 Feb 1972] 5660/72 Heading G5R [Also in Divisions F2 and H2] Gramophone turntable 1 is supported on a fluid bearing 2 (see Division F2), and can be driven by a curvi-linear motor 4, 5 (see Division H2). Speed detecting sensor 11 can provide feedback to a retro-active speed control arrangement. The stator portion 5 of the drive rotor is disposed in a turntable quadrant opposite that occupied by the pick-up.
