Abstract

1433342 Clips STICHTING REACTOR CENTRUM NEDERLAND 10 July 1973 [10 July 1972] 32731/73 Heading E2B [Also in Division F2] A spring clip comprises a base plate 79 and a plate spring 77 having end zones 78 which are fixed to the base plate 79 and parallel to it, the plate spring 77 having an overall bowed formation between the end zones 78 to present a central zone 83 spaced from the base plate 79 and having an intermediate zone e.g. 96 between the central zone 83 and an end zone 78, the intermediate zone 96 having a curvature which is reversed in direction with respect to the overall curvature of the bow.
