Abstract: The present invention relates to the technical field of equipment for impact tests; more specifically, to an instrumented pendulum for Charpy-type impact tests on miniaturized samples. The instrumented pendulum (1) for miniaturized Charpy impact test, according to the present invention, is characterized in that it comprises a main monolithic part, a cleaver (7) housed in an anterior opening of the main monolithic part, and the at least two additional plates (11, 12) removably attached to the respective sides of the main monolithic part of the instrumented pendulum (1). Further, the present invention relates to a Charpy impact machine comprising the instrumented pendulum (1) and an automatic device (6) for releasing the instrumented pendulum (1) at different values of firing angle.

Abstract: The present model refers to a bolted and welded clamp-type repair with bolts and nuts housed in recessed locations that will be hermetically insulated by welding plugging discs to be used in the repair and maintenance of pipes. The clamp-type repair comprises a lower part (1) and an upper part (2) that will perfectly accommodate the pipe, wherein said lower part (1) and upper part (2) each comprise a flanged portion (3) at both ends, and the flanged portions (3) each comprise at least one recess (4) to accommodate the bolt-nut assembly (7) where the plugging discs (8) will be positioned immediately above. The welding process of the edges between the same and next to the pipe (12) and the plugging discs (8) next to the surface of the flanges (3) guarantee the necessary safety and enable the repair to be defined as permanent, without the need for later replacement.

Abstract: The present invention provides a device for removing internal blockage materials (10) from a fluid-conveying line (3), said device comprising a cutting tool (9) activated by a rotary actuator (8), in which: the cutting tool (9) is positioned at the front of the device; and the cutting tool (9) comprises a diameter that is smaller than the internal diameter of the fluid-conveying line (3).
