Title: Method for cutting up a metal tube by induction, and application to the separation of irradiated fuels from their metal sheath
Inventor: ROGER BOEN
IPC: B26F3/06
Filed: 1990-10-05
Abstract: The invention makes it possible to cut a metal tube up by pointwise melting brought about by an inductor. It consists mainly in heating the tube (10) by means of an inductor (4) in order to give rise to the melting of a weak point of the tube (2), thus giving rise to a slit (12) at the ends of which the accumulation of current density causes a permanent rise in the temperature in order to widen the slit (12) thus created. The start point may be brought about by a hole (2) made beforehand in the tube (10). Application to the separation of sheaths from bars of irradiated nuclear fuels.

Title: Strip of three-dimensional fabric and method of manufacture
Inventor: MICHEL VIVES
IPC: D03D3/08
Filed: 1991-10-11
Abstract: The invention relates to a strip of thick three-dimensional fabric, composed of warp fibres (yarns, wires) (3) extending longitudinally in plies which undulate in a zig-zag fashion from one face of the strip to the other and mutually intersect, and of weft fibres (2) arranged in superimposed longitudinal layers and in successive transverse rows, the points of intersection of the warp-fibre plies being aligned in the transverse direction in order to delimit passages housing the weft fibres, these extending over the entire width of the strip. The latter is subdivided into juxtaposed longitudinal sections (I, II, III etc.), and all the weft fibres (2) of at least some of the rows change passage on passing from one section to an adjacent section, each fibre jumping from one passage to a contiguous passage, possibly changing layer, whereas the plies of warp fibres (3) are subdivided into juxtaposed sub-plies (3a, 3b, etc.) delimited like the aforementioned longitudinal sections (I, II, etc.). Such a structure lends itself to the production of helicoidal strips whose thickness increases from the external edge towards the axis.
