Abstract: The present invention concerns a machine for heat treating camshafts, this machine comprising essentially torches likely to produce an electric arc and carried by a carriage which is movable owing to a binary control motor along a horizontal direction parallel to the axis of the camshaft to be treated, this carriage being carried by an intermediate carriage movable owing to another binary control motor along a horizontal direction perpendicular to the axis of the camshaft, which intermediate carriage is mounted in a vertically movable manner on the frame of the machine along a vertical direction perpendicular to the axis of the camshaft owing to still another binary control motor carried by the frame.

Abstract: A device for producing fissile material inside of fabricated nuclear elements so that they can be used to produce power in nuclear power reactors. Fuel elements, for example, of a LWR are placed in pressure tubes in a vessel surrounding a liquid lead-bismuth flowing columnar target. A linear-accelerator proton beam enters the side of the vessel and impinges on the dispersed liquid lead-bismuth columns and produces neutrons which radiate through the surrounding pressure tube assembly or blanket containing the nuclear fuel elements. These neutrons are absorbed by the natural fertile uranium-238 elements and are transformed to fissile plutonium-239. The fertile fuel is thus enriched in fissile material to a concentration whereby they can be used in power reactors. After use in the power reactors, dispensed depleted fuel elements can be reinserted into the pressure tubes surrounding the target and the nuclear fuel regenerated for further burning in the power reactor.
