Abstract: The invention relates to a method for continuous production of a composite material profile by injection-pultrusion from at least one reinforcing fabric and at least one thermoplastic polymer having high fluidity, said method being characterized in that: i) said fabric is continuously pulled with a pulling speed of at least 0.4 m.min?1 in the course of said process; ii) the impregnation stage is performed by injection of a polymeric composition having high fluidity through the fabric; iii) the profile is then shaped with a specific thermal profile. The invention also relates to a profile obtained according to the method of the invention and a composite article comprising such a profile the curvature whereof may be modified in its curvature by bending and/or its profile by rotational molding.

Abstract: The invention relates to the soldering industry. The device comprises a frame supporting a crucible for a bath of molten filler metal, the bottom of the crucible being traversed in fluid-tight manner by a sonotrode sliding under the action of a jack fixed to the frame. An ultrasonic energy generator is associated with the sonotrode and controlled heating means are associated with the crucible. The active end of the sonotrode has a recess with at least one impression of a shape complementary with at least a portion of the outer surface of the parts to be soldered. The jack moves said active end alternately in and out of the bath. The invention is particularly useful for the soldering of aluminum tube cross-heads for heat exchangers.
