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.
