Title: Apparatus for cutting thread
IPC: D01G1/04
Filed: 1973-03-23
Abstract: A method and apparatus for cutting threads, particularly threads formed of mineral substances such as glass, are disclosed. A rotating drum carrying a plurality of radially extending cutting blades operates in conjunction with a rotating support drum which carries and supports the thread for cutting by the cutting blades. Ejector elements carried by the cutting drum and positioned in the spaces between the cutting blades are urged radially outwardly by centrifugal force and compress the thread against the surface of the support drum. The ejector elements then serve to strip cut sections of the thread from between the blades as the cutting blades move away from the support drum. Compressed air is supplied to the spaces between the cutting blades to remove waste material resulting from the cutting operation.

Title: Removable upper tie plate
IPC: G21C3/33
Filed: 1973-10-02
Abstract: In a nuclear power reactor fuel bundle assembled by tie rods extending between the upper and lower tie plates, the upper tie plate is secured by pre-indexed locking cams which are adjustably fitted to the upper ends of the tie rods and which lock into seats machined into the body of the upper tie plate. During assembly of the fuel bundle, the cams are forced through internal passageways in the tie plate which rotate the cams into a position from which they may enter their respective seats, urged by torsion springs fitted onto the tie rods. Compression springs around the fuel rods hold the tie plate in position by maintaining the cams in their seats. The construction facilitates the disassembly of the fuel bundle for removal of defective or spent fuel rods and permit their replacement under remotely controlled conditions.
