Title: Data or information classification system - uses notches in data cards to give negative selection indications
IPC: G06K19/063
Filed: 1974-05-21
Abstract: Classification procedure uses information support cards having edges divided into a series of spaces which can be notched up to their edges. The cards are initially arranged in a file from which they can be removed for the extraction of the data contained on them. The notched edges of the cards indicate the negative "no" selection signals which forbid adding of selection data by notching of the cards. PErforations in the cards form the positive "yes" selection signals. The cards have, along their edges, indications of the speciality, the range and the position of a firm. The spaces relating to this information are notched each time the data does not correspond to that indicated.

Title: Fuel rod assembly for nuclear reactor - prevents damage by own weight and permits use of aluminium alloy sheaths
Inventor: DELAFOSSE JACQUES
IPC: G21C3/356
Filed: 1975-12-31
Abstract: In a fuel assembly of a group of fuel rods, each consisting of a metal sheath for the fissile material, sealed at its ends, the rods are maintained at a definite spacing by grills positioned at intervals according to the length of the rods. Springs projecting from the walls of the cells of the grills support the fuel rods passing through, and the grills in their turn are held between pairs of rigid rectangular frames carried by two side plates extending the full length of the assembly. The two side plates are parallel to and longer than the fuel rods, and are fastened to the frames positioning the grills. In the grills the fuel rods are arranged in parallel rows and the rods of each row are suspended from the rigid structure by a shaft passing through the sealing stoppers of the fuel rod sheaths. The arrangement makes it possible to use sheaths of aluminium alloy. Maintenance is simplified and whilst freedom of movement is allowed at different temps. the rods are uniformly supported and do not rest carrying their own weight on their bottom stoppers.
