Abstract: The present invention in general relates to the field of rearing of commercially relevant mites. More particularly the present invention relates to a mite composition, suitable for the commercial rearing of mites, a method for rearing mites and a rearing device using the composition of the invention, a method for crop protection using the composition according to the invention wherein the mite is selected as a predatory mite, and the use of a carrier material for rearing a mite species.

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: An instrumented, load-sensing washer that can be used on a bolted joint to facilitate determining an axial clamping load of the bolted joint. The washer includes an annular washer body having first and second oppositely disposed axial ends and an outer circumferential sidewall. At least one strain gauge is provided on the circumferential sidewall and is configured to sense a deformation of the washer body do to clamping forces of the bolted joint. The washer further includes a communication assembly operatively coupled with the at least one strain gauge. The communication assembly may include an integrated circuit adapted to receive electrical signals from the at least one strain gauge related to the axial load borne by the washer.

Abstract: A nut includes locking jaws, a floating end of which is actuated by cam profiles inside a rotary actuation ring. The jaws are produced by removing material from the body of the nut, and shift from a locking state to a release state and vice versa by elastic bending deformation. A locking surface on the inside of the jaws has the same thread as the body of the nut.

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.

Abstract: A self-locking screwing attachment device. In one embodiment, the device includes a first element having an inner thread, the first element being screwed onto a threaded tip. In other embodiments, the first element has an outer thread and can either be made of a hollow body or have a closed end so as to constitute, for instance, a borescope.

Abstract: The present invention in general relates to the field of biological crop protection by use of predatory mites. More particularly the present invention relates to a mite composition comprising a predatory mite and a prey. Such a mite composition is suitable for rearing the predatory mite and/or for crop protection using the predatory mite. The prey in the composition comprises individuals of at least one Astigmatid mite species, wherein at least a fraction of the Astigmatid individuals is immobilized. The composition is characterized in that immobilized Astigmatid individuals are contacted with a fungus reducing agent.

Abstract: The invention relates to a shut-off device comprising a plug intended to be placed over a threaded orifice of a casing, or to be removed therefrom, by screwing and unscrewing respectively, the plug comprising a central body bearing a screw thread, and locking and unlocking means that oppose the spontaneous unscrewing of the plug and that are activated automatically by the turning of the plug and its corresponding progression in the direction of screwing along a longitudinal axis. The locking and unlocking means comprise two releaseable coupling members, of which a first member is coupled to and turns with the central body via a protective skirt and of which a second member can be prevented from turning with respect to the casing during screwing.
