Abstract: The process comprises introducing the tubes in the form of horizontal layers (the generator can be positioned horizontally for this purpose), installing anti-vibratory bars on the layers, placing weights on the bars and checking the clearances between the tubes and the bars, so that the tubes falling outside the accepted tolerances can be replaced. This is followed by the installation of the layer of tubes immediately above it. This procedure is repeated until all the layers have been installed. The invention is used in the steam generators of nuclear power stations.

Abstract: Terminal crimping apparatus having crimping dies and crimping anvils and strip feeding means for feeding terminal strip to a crimping zone between the dies and anvils has a strip lifter mounted on the press ram which lifts the strip above the level of the crimping anvils after completion of a crimping operation. The strip lifter prevents misfeeding of the strip in that after being lifted, the strip is above the surface of the anvil assembly and can be fed therepast in preparation for the next crimping cycle.
