Abstract

580,171. Making valves. MUNTZ & CO., Ltd., A., and FARMER, H. O. Jan. 15, 1942, No. 638. [Class 83 (ii)] [Also in Group XXIX] The flaps 36A, 36B, Fig. 3, of a non-return valve (see Group XXIX), suitable for air compressors, are punched from steel strip, e.g. spring steel or 18-8 chromium-nickel steel, rolled in a direction at right angles to the lines of bending of the flaps. The flaps are punched a little larger than the finished size and reduced by grinding.
