IPC: G21C19/48
Filed: 1968-11-20
Abstract: Apparatus for the treatment of spent fuel elements consisting of ceramic fuel pellets within a stainless steel can comprises, Fig. 1, a shear 14 for cutting a fuel element 10 into short fragments 12, these fragments dropping into the hopper 16 of a ball mill 18. The ball mill drum 20 is inclined and rotated on journals 22 by a motor 40, compartments formed by partitions 26 receiving the balls 30. Openings 28 in the partitions 26 permit passage of the fragments 12 but are too small to receive the balls. Longitudinal ribs 32 on the drum continually raise the balls as the drum rotates, the hammering action on the fragments 12 causing the fuel to leave the can fragments and to be reduced to powder. The powdered fuel and can fragments leave the mill 18 through a spout 34 and drop on to a vibratory screen 36, the latter separating the powder which drops into a collector 38. A modified apparatus, Fig. 2, additionally permitting fluorination treatment of UO 2 -PUO 2 fuel comprises a drum extension 44, 46 provided with heating means (not shown). This extension is supplied with hydrofluoric acid through a pipe 48 and with oxygen through a pipe 50. In part 44 of the extension, which is heated to about 400 C., the UO 2 is oxidized to form U 3 O 8 and is partially fluorinated. In part 46 of the extension, which is heated to about 500 C., prefluorination to form UF 4 and PuF 4 is completed. The empty can fragments, the fission products which have not undergone the fluorination reaction and the mixture of tetra-fluorides are collected in the lock-chamber 54.

Patent ES-393749-A1 (ES)
Title: Apparatus for manipulating an oxygen injection lance
IPC: C21C5/46
Filed: 1971-07-29
Abstract: Hoisting mechanism for an oxygen lance includes a counterweighted lance carriage driven by a hoist system made up of a motor driven traction drum, guide sheaves and cables. The weight of the counterweight offsets the weight of the carriage, lance, hose complex attached to the lance, and skull build-up on the lance. In normal operation, the counterweight is elevated as carriage is lowered by the hoist system to insert the lance into an oxygen converter and conversely the counterweight is lowered when the carriage is raised by the hoist system to withdraw the lance from the converter. In the event there is a power failure which impairs operation of the hoist system, the counterweight descends by gravity causing the carriage and lance to travel upwardly upon freeing the traction drum from restraint normally applied during the blowing operation of the converter.

Title: Apparatus for the automatic classifying and finding of groupings of series of distinguishing signs according to the risks of conflict they involve with given groupings
IPC: G06F17/30
Filed: 1974-04-13
Abstract: A method and apparatus are disclosed for automatically finding and classifying any group of trademarks belonging to an initial series and having similarities with groups of trademarks of another series. The classification is arranged in increasing or decreasing order according to the risks of conflict involved in these similarities. The analysis of the similarities provides an indication of the likelihood of confusion between trademarks which are proposed to be registered and those already registered. The apparatus includes a memory for storing the first and second groupings of trademarks. The groupings are then analyzed in pairs by a comparing and counting device which determines for each pair the numbers of the shortest and longest groupings, the longest sequence of common signs to both groupings, the number of signs common to both groupings other than those in the sequence and the number of signs of the longest groupings not found in the other grouping. These various quantities are then used to compute a coefficient of simularity which is in turn used to compute the evaluation of the risk of conflict. The computed risks of conflict exceeding a predetermined value are classified in ascending or descending order and printed for final evaluation.
