Abstract: The process serves for the welding of halogen-free thermoplastic films (1, 2) or sheets with interposed inserts (3, 4), for example reinforcing inserts, using a welding device with a welding tool (5') which can be heated to the desired welding temperature and a counter-tool (5) which is adjustable to a temperature lying below the melting point of the films. The counter-tool (5) has a profiling corresponding to the desired welding or embossing contour (8), in particular a cutting edge (7). The thermal energy necessary for plasticating the films (1, 2) can be introduced to the latter through a heat-conducting separating foil (11) which can be introduced into the welding device. According to the invention, the welding of thermoplastic films which consist of preformed lower films (1) and upper films (2) is possible by the following process steps:   - spatial preforming of at least one of the two films in a thermoforming process to form a depression with respect to an elevated film-supporting edge, - supporting the preformed lower film (1) in the region of the film-supporting edge before or after the insertion of the insert into the depression, - application of the other film (2) onto the insert and onto the supporting edge, - aligning or centring the films (1, 2), by means of the separating foil (11) which is designed in the form of a mask extending only along the supporting edge, in the region between the welding tool (5') and counter-tool (5) and - welding the films (1, 2) in the supporting-edge region with the interposition of the separating foil (11), shaped corresponding to the supporting-edge profile, between the welding tool (5') and the films (1, 2).   <IMAGE>

Abstract: A conventional low pressure coolant injection system for boiling water reactors is provided. With the modification, the cross tie conduits and associated valves remain open between two LPCI divisions. On the occasion of a LOCA, the LPCI pumps (90,91) are activated and injection valves (120,124) for each of the LPCI divisions are opened to commence coolant injection in the recirculation loops (56,57) in simultaneous fashion. However, the rate of flow of water coolant within each injection system is controlled by a hydraulic resistance (118), which is selected to achieve reactor core cooling within requisite time and in requisite quantities from one injection path. Thus, even though coolant water may flow through a rupture within one recirculation loops, sufficient water will be injected in the other loop to achieve core cooling.

Abstract: Procédé et appareil à écho-impulsion ultrasonique amélioré s'appliquant notamment à des mesures de précision de compressibilité dans n'importe quelle matière de rétrodiffusion, notamment des tissus organiques. Le procédé utilise un transducteur classique ou un dispositif contenant un transducteur, lequel est déplacé transaxialement, comprimant ou déplaçant ainsi une région proximale d'un corps cible par de petits incréments connus. A chaque incrément, une impulsion est émise et une séquence d'échos (ligne A) est détectée à partir de régions situées dans la cible le long du chemin de déplacement des ultrasons ou du faisceau du transducteur. Les décalages temporels résultant au niveau des segments d'écho correspondant à des caractéristiques de la cible, corrigés en fonction des régions de vitesse d'ultrasons variables dans le chemin des ultrasons, fournissent des informations relatives et quantitatives sur les contraintes provoquées par les compressions. L'effort que le transducteur et le dispositif conteneur font subir est également déterminé et corrigé en fonction des profondeurs sur le chemin des ultrasons. Les valeurs appropriées d'effort sont divisées en les valeurs respectives de contrainte le long de chaque chemin afin de produire un élastogramme, ou un réseau de valeurs de compressibilité, de la cible.
