Abstract

920,430. Embossing. GENERAL ELECTRIC CO. Ltd. Sept. 28, 1961 [Oct. 5, 1960], No. 34146/60. Addition to 851,867. Class 100(2). [Also in Groups V, XV, XXII and XXIII] A surface is figured with a regular pattern of closely spaced octagonal pyramids by cutting on the surface a first set of equally spaced parallel grooves 3a, 3b, 3c ... (Fig. 3), cutting a second set of equally spaced parallel grooves 4a, 4b, 4c . . . perpendicular to the first set, cutting a third set of equally spaced parallel grooves 6a, 6b, 6c . . . with their apex lines along the first diagonals of alternate rectangles in the rows of common-sided rectangles into which the surface is divided by the apex lines of the first two sets of grooves, and cutting a fourth set of equally spaced parallel grooves 7a, 7b, 7c . . . with their apex lines along the second diagonals of the same set of alternate rectangles, the grooves all being of substantially V-shape cross-section and of a width and spacing such as to form the said pyramids. The other features of the invention such as configuration of grooves, the material the surface of which is cut, use of the plate to form a die &c. are as in the parent Specification.
