Abstract
1302098 Article engaging devices COMMISSARIAT A L'ENERGIE ATOMIQUE 2 April 1970 [2 April 1969] 15768/70 Heading B8H A grab for use, e.g. in engaging a reactor control rod comprises a cylindrical bush 2 in which two fingers 15, 16 are pivotally mounted on trunnions 14 and which in their normal positions abut each other at their lower ends, but in use of the device are moved into engagement with the head 9 of the control rod by means of a member 20 mounted on a vertically movable rod 19, projections 15a, 16a engaging a groove 10, the fingers 15, 16 having butts 15b, 16b which, when the rod 19 is raised to cause retraction of the fingers 15, 16 to their normal position and thus release the head 9, bear against the top of the head 9 to prevent it from wedging or jamming.
