At least one cylinder having electrically conductive portions and in tangential contact with a metallic tube is associated with a tank filled with electrolyte which is brought to the contact surface between cylinder and tube as a result of rotational motion imparted to the cylinder or to the tube by suitable driving means. An electric current generator is connected to the metallic tube and to at least one of the conductive portions of the cylinder.

Electrolytic device for marking metallic parts

Each fuel pin of the cluster is fitted with a spacer element wound in a coarse-pitch helix on the external surface of the fuel can and attached to end-caps of the can. The spacer element consists of a deformable tube having a constant initial cross-section, the tube being fitted internally with a reinforcement wire which is mounted within the tube with provision for a clearance space and extends over the entire length of the tube.
