Abstract: A remote manipulator of a tool has a body provided with a fixed jaw and a slide provided with a mobile jaw able to be displaced linearly, actuators located at a distance and coupled to the tool via a cable integral with a side of the slide and sliding inside a flexible sheath having one end integral with the body. The actuators have two arms each associated respectively to a handle and able to be separated angularly from each other by rotation about an axis by a value such that the distance between their free ends is at least equal to the maximum linear displacement of the slide bearing the mobile jaw, when the two handles are brought close to one another.

Abstract: A device for locking/unlocking the movement of a notched member, comprising a toothed wheel, having a coaxial bore and whereof the teeth have a pitch equal to that of the member, and a fixed shaft about which is mounted the toothed wheel, the shaft has a diameter less than that of the bore of the wheel such that, subsequent to a radial clearance, the wheel is capable of moving between a centered unlocking position wherein the tops of the teeth of the notched member closest to the wheel, are located outside the pitch circle P of the wheel and the member can then move freely, and an off-center locking position, when the member exerts on the wheel a force F directed towards the axis of the shaft, position wherein the top of the tooth of the member is located, between two teeth of the wheel, inside the pitch circle P, so that the member and the wheel are mutually locked.

Abstract: A method and an implementation equipment for fixing an elastic clamp band (1) to the lugs (5) particularly adapted for re-current mounting of a flexible connection pipe (12) on a pipe system (13). An automatic dispenser (2) of clamp bands (1) is arranged to position each clamp band (1) such that its two lugs are externally accessible to be seized by the grips (9, 52, 103) of a hand tool for extracting and fixing (8, 50, 100) which are brought together to compress the lugs (5) of the clamp band (1) by external (11) separately controlled actuators. The tool (8, 50, 100) comprises elements for bringing together the grips (9, 52, 103)) freely and reversibly when the external actuators (11) are activated and elements for releasing them instantly or gradually at the desired moment with an external control (14, 123).

Abstract: The invention concerns a device for locking/unlocking the movement of a notched member (1), characterized in that it comprises a toothed wheel (2), having a coaxial bore (3c) and whereof the teeth (3a) have a pitch equal to that of the member, and a fixed shaft (4) about which is mounted the toothed wheel (2), said shaft (4) having a diameter leess than that of the bore of the wheel (2) such that, subsequent to a radial clearance (5), the wheel is capable of moving between a centred unlocking position wherein the tops of the teeth (1a) of the notched member closest to the wheel (2), are located outside the pitch circle P of the wheel and the member (1) can then move freely, and an off-centre locking position, when the member (1) exerts on the wheel (2) a force F directed towards the axis (O1) of the shaft (4), position wherein the top of the tooth (1a) of the member (1) is located, between two teeth (3a) of the wheel (2), inside the pitch circle P, so that the member (1) and the wheel (2) are mutually locked.

Abstract: A hand-held apparatus for cutting transversely a pipe using a slitter co-operating with rollers to produce a deepening cut, is formed of two half-shells mounted opposite around the pipe with adjustable clamping elements one at least supporting a slitter or radially mobile, in the cutting plane, and the other, at least two rollers rotating in the cutting plane and arranged in pair facing each slitter on the other half-shell to compensate the cutting force in the assembly rotation about the pipe resulting from the cooperation between a tangential driving tool and catching elements distributed over the outer surface or on the periphery of each half-shell.

Abstract: A device for the remote handling of equipment (4) for instance designed for mounting elastic rings (6) comprises a fixed jaw (8) and a mobile jaw (12) which moves linearly relative to the fixed jaw (8) by actuating elements coupled to the equipment (4) by a cable (2) connected to the mobile jaw (12) inside a sheath (3) one end of which comes to stop (10) on the fixed jaw (8). The actuating elements consist of two branches (13, 14) articulated on a common axis (15) such that the distance between their free end (131, 141) is not less than the maximum displacement of the mobile jaw (12), when bringing closer the two handles (16, 17) respectively integral with the two branches (13, 14) of which the free end (131) of one (13) acts as a stop to the other end of the sheath (3) while allowing the cable (2) that is connected to the free end (14) of the other arm (14) to slide.
