摘要： In an assembly of two parts having flat assembly faces, the upper part has a bore provided with an ovalized orifice and the lower part has an internally-threaded bore, the two bores being coaxial when the parts are in the assembly position. A first connecting member has a threaded end in cooperating relation with the internally-threaded bore and a second connecting member has a portion in contact with one face of the upper part. One member has an ovalized portion which cooperates with the ovalized orifice and has a deformable portion which cooperates with the other member after crimping in order to secure the two members at least against rotational motion.

摘要： In a pressurized water reactor, the pressure vessel contains a plurality of fuel wrappers of parallelepipedal section supported on a lower grid which carries projecting sleeves equal in number to the wrappers. Each sleeve penetrates into a bore of a wrapper base plate and has a higher coefficient of thermal expansion than the base plate so that its external diameter is smaller than that of the bore in the cold state and equal thereto at the operating temperature of the reactor. The bore is thus clamped against the sleeve as a result of thermal expansion, the fuel assemblies being secured within the wrappers by means of spring-type elastic devices.

摘要： The present patent application belongs to the field of workplace safety equipment and proposes an improvement to a device provided with a hook for anchoring a ladder to cables. The ladder is formed by a main structure (1) having in the center thereof an articulated hook (2). The main structure (1) comprises an extensible shaft in the upper portion thereof, allowing it to be coupled between two steps of a service ladder. In order to overcome drawbacks, a rope holder (8) has been developed, which is arranged in the lower portion of the main structure and locks the rope tying the hook (2), preventing the hook (2) from turning upside down or from opening. The rope holder also has two lateral toroidal locks (18) coupled to the step (20) of the ladder, each on one side of the main structure (1), preventing the main structure from shifting
