Abstract

1,003,330. Supporting gramophone pick-ups. ASTATIC CORPORATION. Nov. 13, 1962, No. 42784/62. Heading G5R. Mutually repelling magnets 41, 42 provide a non-linear compliance between a bracket 30 secured to a pick-up arm 11 and a cartridge 10, pivoted to it. In Fig. 2, the cartridge 10, pivoted at 37 is balanced by a fixed counterweight 39, while in Fig. 3 an available, commercial cartridge is attached to the bracket at 57 and is balanced by an adjustable weight 54. The non-linear relation between the force and distance between the magnets provides improved vertical damping, as compared with known spring arrangements. The application to an automatic record-changer (Fig. 1, not shown) with a 3 gm. tracking load at the stylus is detailed.
