    摘要: The invention concerns a method for non-destructive ultrasonic control, combining time-of-flight diffraction (TOFD) and inclined longitudinal wave techniques, of weld joints assembling two abutted parts. The method consists of using the time-of-flight diffraction technique, displacing in the longitudinal or circumferential direction, along the weld joint to be controlled, at least one pair consisting of a first transducer and of a second transducer, one transmitting and the other receiving ultrasonic waves, these transducers being laterally positioned on either side of the joint to be controlled, these transducers comprising piezoelectric ceramics or crystals. Furthermore, it consists of displacing along the welded joint to be controlled, using the inclined longitudinal wave technique, at least a third transducer, so as to detect any defect of the joint located at a thickness ranging between 0.5 mm and 15 mm.

    摘要: An installation to provide data concerning an object. An electronic label, which includes data storage, is fixed on the object. The installation is capable of reading least part of the data stored by the label and is also capable of accessing a database which contains data concerning the object. The database is associated with an address in that database locating information is stored in the electronic label. The database is accessed on the basis of this locating data, which may be read by a reader. The installation may be used for marking and tracing gas packages.

    摘要: A fluid expansion valve with a main body and a method of its use. The main body has an internal fluid passage and an outlet connector. The outlet connector is suitable for delivering the expanded fluid and for connecting with a socket. The internal profile of the socket is suited for connection with the external profile of the outlet connect. The outlet connect has three connention sections of varying external diameters. The valve may be used to introduce a pressurized gas to a liquid or a beverage.
