Abstract: The invention relates to a process for producing welded steel pipes with a high degree of strength, ductility and deformability, especially line pipes, according to the UOE-process. A pipe is molded cold from a TM-rolled sheet, welded together and sized to the desired diameter. Starting with a sheet consisting of a steel with (in wt.%): 0.02 to 0.20 % carbon, 0.05 to 0.50 % silicon, 0.50 to 2.50 % manganese, 0.003 to 0.06 % aluminum, the remainder being iron with potentially other production-related impurities, the pipe is after welding and sizing being subjected to a heat treatment process at a temperature of 100-300 degrees Celsius and for a holding time that is adapted to the thickness of the pipe wall, with subsequent cooling with air or by forced cooling. The resulting pipe is resistant to aging and has a sufficiently integral deformation reserve against fracturing with the same high degree of strength, without exceeding the upper limit for the ratio of yield strength to tensile stress according to the current regulations for conventional steels.

Abstract: La présente invention concerne une poutre de construction (100) comprenant une paire d'éléments (102, 104) latéraux et une armature (106) souple s'étendant entre eux, de manière à présenter un profil en coupe correspondant aux éléments de poutres de constructions fréquemment utilisés (par exemple, 2" x 4" ou 2" x 6" (5,08 cm x 10,16 cm or 5,08 cm x 15,24)). La souplesse de l'armature permet de réduire la transmission de son à travers la poutre d'un élément latéral à un autre. En particulier, dans un cadre mural, les éléments latéraux sont montés à des extrémités opposées de celui-ci sur des plaques d'extrémité composées d'autres poutres de construction correspondant à cette invention (c'est à dire, une paire d'éléments latéraux avec une armature souple s'étendant entre eux). Lorsque le cadre mural est utilisé dans une structure de construction, les éléments latéraux des plaques d'extrémité sur la même face sont fixés à la structure périphérique, laissant ainsi l'autre face du cadre flottant librement de façon souple. Un mur est monté sur le côté flottant librement du cadre mural afin de former un mur flottant librement de façon souple agissant comme un absorbeur "diaphragmatique" d'atténuation du son. De préférence (mais pas nécessairement) l'armature comprend des écarteurs (410), de sorte que les éléments latéraux puissent être facilement orientés par rapport à l'armature et l'un par rapport à l'autre, afin de s'ajuster automatiquement. Par commodité, les écarteurs peuvent être formés en coupant et en pliant des pattes dans le matériau de l'armature dans des endroits voulus.

Abstract: a mud pulse telemetry adaptive noise canceller (ANC) is provided to provide information on down hole conditions during a Measurement-While-Drilling/Logging-While-Drilling (MWD/LWD) operation. The ANC (181) employs a Signal Conditioning Box (175), Anti-Abasing Filter (177) and two transducers, each receiving a succession of signals due to a transmission device~ (158). A primary transducer (163), located downhole from both a mud pump (151) and a desurger, receives a primary signal. A reference transducer (165), located near the mud pump (151) and upstream from the desurger (153), receives a reference signal. The ANC linearly relates the reference signal to the primary signal by means of a recursive least squares algorithm and calculates weighting coefficients. The ANC (181) uses weighing coefficients to process a subsequent primary signal, thus enhancing transmission of MWD and/or LWD data thru a downhole drillpipe (157) via the medium of Mud Flow (155).
