Abstract
1,011,741. Rotary abrasive tools. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 25, 1962 [Sept. 28, 1961], No. 36401/62. Addition to 979,058. Heading B3D. The apparatus claimed in the parent Specification for treating curved glass surfaces has a fluid-filled envelope 11 of elastic material interposed between a loading plate 12 and the foamed rubber or plastic carrier 1 for the grinding or polishing plate 2. The envelope 11 may be a rubber ring filled with liquid or gas and the loading plate may be of iron or other heavy material, the underside of the ring 11 being preferably shaped to the curvature of the carrier 1, or it may be of trapezoidal crosssection. A driving member 6 comprising a sleeve 7 and a universal joint 8 may be driven through gearing (not shown) to rotate the carrier. Polishing fluid is fed through openings 9 and 10. Springs 19 are interposed between the plate 12 and an adjustable ring 18 on the sleeve 7 to permit of variation of the operative pressure. In a modification, Fig. 2 (not shown), the universal joint is omitted and a lighter loading plate is directly attached to the sleeve 7. As applied to the polishing of the face 26, Fig. 3, of a television tube, the carrier 1 extends partly beyond the edge of the face, and supports 27 of hard material and of the same curvature as the face are provided on a table 25 on which the tube is mounted; the table and carrier are rotatable in opposite directions, and the rotational axis of the driving member is inclined relative to the axis of rotation of the surface under treatment.
