Abstract
384,531. Gramophone pich-ups. PAILLARD ET CIE SOC. ANON., E., Ste-Croix, Switzerland. April 15, 1932, No. 10819. Convention date, April 22, 1931. [Class 40 (iv).] In order to minimize tracking error as the needle of a gramophone pick-up passes across the record, instead of fixing the pickup at an inclination to the carrying-arms the pickup itself is so constructed that the vertical plane passing through the axis of oscillation of the armature forms an angle other than 90‹ with the plane of the magnetic circuit. With this arrangement, the pick-up can be fixed to the carrying-arm with it body normal to the arm. In the construction shown, the polepieces 12, 13 of the magnet 11 are so formed that the air gap between them is inclined to the plane of the magnet, Fig. 4. The armature 14, which is of square section, is mounted within a surrounding mass of rubber in the air gap so that the armature is thus virtually pivoted on an axis inclined to the plane of the magnet.
