Abstract: An ultrasound method and device for inspecting the bulk of a weld for the presence of defects are provided. The method includes a step of studying the weld metallurgically; a step of dividing the weld into a plurality of theoretical blocks and of jointly determining an elastic Hooke tensor for each theoretical block; a step of simulating by calculation the propagation of at least one incident ultrasound wave through the weld; a step of simulating at least one reference diffracted ultrasound wave; a step of emitting at least one incident ultrasound wave into the weld; a step of measuring each diffracted ultrasound wave; and a step of comparing each reference diffracted ultrasound wave with each measured diffracted ultrasound wave.

Abstract: The present invention relates to a device for improving the fatigue strength of a metal pipe a portion of which lies on the sea bottom and one end of which is suspended from a floating support subjected to the dynamic motions of the sea which move the touchdown point (TDP) of the pipe. The device comprises stress limiting means comprising a material (13) inserted between the pipe and the ground, in the vicinity of the touchdown point, the system thus created having a lineic stiffness below 200 kN/m/m and a thickness determined in such a way that the static and cyclic deformations remain allowable.

Abstract: A tubular coupling element for producing a glued joint with a fluid line and a method for producing such a glued joint. The coupling element includes an inner tube that is insertable into a fluid line and an outer tube that is constructed concentric to the inner tube and integrally connected to the rear end of the inner tube by a connecting wall. An annular gap is present between the two tubes and is designed to receive an end section of the fluid line and a hot-melt type adhesive in a compacted solid form shaped as a ring. A connection between the coupling element and the fluid lines can be easily established by first introducing the adhesive in the annular gap and then melting it by rapidly supplying heat while the end section of the fluid line is pressed into the annular gap of the coupling element.

Abstract: A rotatable stopcock for a plug-type coupling with an angled piece for connecting fluid lines. The stopcock including a turning knob portion and an integrally formed hollow pin portion. The knob portion includes two opposing ring segments having detent catches that positively engage a flange ring formed on the coupling housing wall. The pin portion is dimensioned to be received into a contact hole of the plug-type coupling such that rotating the stopcock after insertion causes the hollow pin portion to regulate the fluid flow through the plug-type coupling.

Abstract: The invention relates to a rotatable stopcock inserted into a male coupling (2) having a 90° offset connecting piece (3) for connecting to fluid lines. A contact hole (6) for receiving a female pin (8), which is connected to the stopcock (1) and which is provided with a continuous hole (9) having a 90° angle curve for connecting the coupling housing (5) to the connecting piece (3), is situated along the straight extension of the male coupling (2), and the end of the said female pin is connected to a turning knob (7) while forming one piece. In order to be able to securely fix the stopcock (1) to the coupling housing (5) after insertion into the contact hole (6), the housing wall (10) comprises a peripheral flange ring (11) on the contact hole (6). For the same purpose, two ring segments (13) located opposite one another are shaped onto the front wall (12) of the turning knob (7).

Abstract: The invention relates to processes for the preparation of compounds of formula (I) wherein R1 and R2 each independently represent a halogen atom.

Abstract: A connection unit of a releasable quick coupling that includes a cylindrical housing head, connecting sleeve, support sleeve and a ceiling ring. The cylindrical housing head defines a receiving space and includes a retaining element having movable edges that are directed into the receiving space. A tubular inserting part having a encircling retaining rib is insertable into the receiving space such that the retaining rib is engaged by the retaining element. The connecting sleeve is molded an end of the housing head and is adapted to be inserted into the end of the pipeline. The body of the connecting sleeve and detents of the housing head form a mounting space that is adapted to receive and secure an edge of the pipeline. Additionally, a support sleeve is mounted on the connecting sleeve at a second end opposite said housing head. Finally, a sealing ring is disposed within the support sleeve.

Abstract: Compounds of formula (I) are prepared by hydrogenolysis of a compound of formula (II): where R1 is haloalkyl, haloalkoxy or −SF5; W is N or CR3; and R2 and R3 are H or Cl. The compounds of formula (I) can be used as intermediates in the preparation of pesticidally active arylpyrazole compounds.

Abstract: The present invention relate to a device and to a method for handling a pipe (1) comprising at least one metal tube plastically wound on a drum (2). The invention comprises an adjustable straightening system (5) controlled by at least one series of means (6, 7) for measuring the stresses present in the material of the tube once unwound from the drum. The present invention can be used for floating supports intended for offshore laying of uncoiled rigid tubes or for units referred to as “coiled tubing” used in oil wells for drilling or well servicing.
