A measurement system comprising a sensor and a controller configured to communicate with the sensor, the controller comprising a display. The sensor comprises at least two measurement assemblies and at least one processing circuit connected to one or more sensing elements each measuring a current value of the same parameter. Each processing circuit emits to the controller a measurement signal as a function of the current value measured by the one or more sensing elements and of a stored reference value. The controller is configured: i) to transmit the reference value to each processing circuit that stores it if the reference value is equal to within a margin of the measured current value, and ii) to receive the measurement signals and display respective symbols on the display, the symbols being at least dissimilar or displayed alternately.

Abstract

A nut is prevented from turning during screwing by a body attached to one of the parts to be tightened by rivets. The body prevents the nut from rotating via a ring coupled without clearance with the nut and coupled with radial clearance to the body, in order to allow the nut to self-position itself along the axis imposed on the screw by the bores traversed by the screw. The nut can thus be a standard nut or a floating cage nut. Application to the retaining of nuts that are inaccessible and/or require a high level of security against unintentional unscrewing.

Abstract

A nut (2) is prevented from turning during screwing by a body (12) attached to one of the parts to be tightened (6) by rivets (14). The body (12) prevents the nut (19) from rotating via a ring (19) coupled without clearance with the nut (19) and coupled with radial clearance to the body (12), in order to allow the nut to self-position itself along the axis (3) imposed on the screw (4) by the bores (9, 11) traversed by the screw. The nut can thus be a standard nut or a floating cage nut. Application to the retaining of nuts that are inaccessible and/or require a high level of security against unintentional unscrewing.

Abstract

A sealing device in the form of a plug that is receivable in a threaded hole of a case includes a threaded central body, a skirt connected to the central body, and locking/unlocking means that opposes spontaneous unscrewing of the plug and is automatically activated by rotation of the plug and corresponding movement along an axis. The locking/unlocking means includes a first releasable coupling component coupled for rotation with the central body, and a second releasable coupling component facing the first coupling component at least during screwing and unscrewing. In at least in a tightened condition of the plug, the second coupling component is secured against rotation relative to the case by rotation restricting means located inside the threaded bore. In the screwed condition, an annular end face of the skirt bears against a bearing face of the second releasable coupling component to transmit tightening thrust to the case.

Abstract

A nut for securing first and second pipe end-pieces together includes a nut lock having a stop member secured to the nut body, and a second element which is rotatable inside the nut body and having a locking feature adapted to lock onto a corresponding locking structure of the second end-piece. The stop member and the second element include corresponding face teeth which are urged to intermesh by an axial compression spring. At or near the tightened condition of the assembly, the second element is locked onto the second end-piece so that rotation of the nut is possible only if the torque applied exceeds a given threshold, for which the face teeth jump over each other while the spring is alternately stressed. A compact design is obtained with the lock positioned at the rear of the nut thread. The clamping face is axially between the nut thread and the lock.
