Abrégé

The system for attaching a load (E) allows rapid release of the attached load (E), at least when the load is pulled. It comprises a mounting plate (11) designed to be fixed to the load (E), an attachment device (10) and a breaker. The attachment device (10) comprising a connecting means (100) which allows the attachment device (10) to be secured to a pulling element (2), a rigid attachment element (101), which allows the attachment device (10) to be attached to the mounting plate (11), and a pulling element which connects the connecting means (100) to the attachment element (101), and which comprises a breakable part that has an axis of pulling that is fixed in relation to the attachment element (101). The attachment system further comprises positioning and blocking means which, when the attachment device (10) is attached to the mounting plate (11) and a pulling force (T) having at least one pulling component (Tz) which is parallel to the axis of pulling and in the opposite direction to the attachment element (101) is applied to the connecting means (100), allows the said breakable part of the pulling element (102) to be positioned and immobilized with respect to the breaker (12), the pulling element making it possible to transmit to the attachment element (101) at least the said pulling component (Tz), and the breaker (12) being able, once the attachment device (10) is attached to the mounting plate (11), to break the said pulling element in two at the said breakable part so as to detach the mounting plate (11) from the connecting means (100).

The device (1) for attaching a load (E), such as a lifeboat (E) for example, comprises a hook (12) designed to accept a top link (2) at the end of a mechanical connecting element (3), and release means that allow said top link (2) attached in the hook (12) to be released quickly. The release means comprise a breaker (11), for example of pyrotechnic, hydraulic or pneumatic type, designed to cut through the top link (2) attached to the hook (12), particularly when the connecting element (3) is taut.

Abrégé

The invention relates to a cable (1) provided with marks (2), which are fixed at predefined intervals along the cable. The measurement device comprises an electronic detection means (6), which is suitable for automatically detecting, on the moving cable (1), every local change in the transverse geometry linked to the presence of a mark (2). More specifically, the device can also comprise a wheel (3) suitable for being rotated by the cable (1), an encoder (4) suitable for detecting the number of turns made by the wheel (3), and an electronic acquisition and processing means for calculating a corrected cable length according to the number of wheel turns detected by the encoder (4) and the detection signal provided by the electronic mark detection means (6).

Abrégé

The present invention relates to a device for automatically and autonomously releasing a mechanical cable or rope (4) connection between two elements, in a zone having explosive atmospheric conditions, comprising: a mechanical assembly (11) in the form of an enclosure (21) which can be traversed by a cable or rope (4) and which contains at least one sectioner comprising a chisel (25) associated with an anvil (20) and means for moving the chisel (25) with respect to the anvil in order to cut the cable or rope (4), means (15A, 15B, 15C) for positioning the cable or rope (4) making it possible to pass the cable or rope (4) between the anvil (20) and the chisel (25), and means (16) for measuring the tension of the cable or rope (4); the control means (12) making it possible to automatically trigger the sectioner. The chisel (25) and preferably the anvil (20) are made of an anti-spark material, particularly of a beryllium-copper (Be-Cu) alloy.
