Abstract: For removing contaminant alkali- and alkaline earth metal contaminants, particularly Li, a particulate aluminium fluoride-containing material is introduced into a vortex established in a non-cylindrical body of molten aluminium contained in a vessel. 
     The generation of the vortex establishes currents having both downward and lateral components at the bottom of the vortex and upwardly spiralling currents at the periphery of the vessel, which serve to recirculate suspended matter. 
     The stirring of the molten metal is continued until the contaminant level is reduced to a desired level and then the molten A1 is separated from the reaction products. 
     The body of metal is contained in a vessel which is non-cylindrical and/or has its axis inclined to the vertical.

Abstract: Apparatus and process for supervising and controlling the operations of loading and unloading of fuel of a nuclear reactor comprising an information processor 30 formed from several units. A treatment unit 31 receives control signals giving notably the position, the speed, the load of machines 7 and 16 operating the loadings and unloadings of groups in the core 2, the reactor pool 3, and the spent fuel pit 14. A programmable unit 34 furnishes command signals, previously recorded, representing the loading sequence. The command and control signals are treated in a central calculating unit 35 which, while considering the information furnished by the permanent memory unit 32 and by the temporary memory unit 33 gives on one hand the coordinates of all sites for the groups, and on the other hand the coordinates of the places of the movable elements as well as the identification marks and positions of each group, compares the different signals received, and according to their coincidence, authorizes or arrests the directed movement. The temporary memory unit 33 saves the last position acquired while erasing the previously occupied positions, while the control box 37 records all of the movements executed.

Title: Connecting device with a heat-recoverable metal driver member
Inventor: MCGAFFIGAN THOMAS HAYNES
IPC: H01R4/58
Filed: 1983-10-20
Abstract: A reusable heat-recoverable connecting device (20) has an annular driver member (22) and a circumferentially split annular spring biasing means (24) inside and generally concentric with the driver member (22). The spring biasing means (24) exerts an outward radial force against the inside surface of the driver member (22). The driver member is made from a heat-recoverable metal having a martensitic state and an austenitic state. The driver member (22) is expanded radially outward by the spring biasing means (24) when the driver member (22) is in its martensitic state to facilitate insertion of a substrate. The driver member (22) recovers to its non-expanded dimension when it returns to its austenitic state to cause engagement between the spring biasing means (24) and the inserted substrate.

Abstract: Le synchroniseur de données permet de résoudre les problèmes posés par l'inadaptation d'équipements d'enregistrement et d'analyse et peut être utilisé pour des enregistrements à canaux multiples. A la suite d'une analyse préliminaire, un point de référence est disposé sur le signal d'enregistrement et utilisé pour déclancher le processeur de données. Chaque canal de l'enregistreur est ensuite reproduit et envoyé au processeur de données en utilisant le synchroniseur de données pour produire le signal pour le processeur de données. Chaque canal peut être ainsi analysé avec la même référence de temps. Le synchroniseur de données (BS) décode le signal numérique enregistré à trois niveaux pendant la reproduction et produit une impulsion de synchronisation de sortie pour déclancher de l'extérieur le système d'ordinateur. Cette impulsion a lieu au même instant par rapport aux données enregistrées chaque fois que la bande est reproduite, indépendamment de la vitesse de reproduction.
