Abstract: The investigation on the stress relief of magnetic materials is important both for the industrial process and the academic research. In this work, the stress effects on the magnetic characteristics in Fe-based metallic glasses (MGs) are investigated under the applied bending stress and various annealing treatments. It was found that both the magnetic induction intensity B and effective permeability μ′ decrease while coercivity Hc increases with the applied compressive stress, indicating that the compressive effect is dominant on the magnetic characteristics in Fe78Si9B13 MG ribbons. We also found that the wide domain wall movement and the rotation of the narrow domains are seriously affected by internal stress during the magnetization process. Our results reveal that the stress relief plays a critical role in improving magnetic properties of Fe-based MGs and are helpful for understanding the correlations between the stress, microstructure change and magnetic softness in magnetic MGs.

Abstract: A method for storing and distributing various articles, according to which the objects are stored on the trays of a rack structure. A suitable extraction system driven by a control and command system is movable in front of the rack structure in such a way that the extraction system is aligned in front of the bay of a tray carrying the stock of articles corresponding to the selected object so as to remove at least one of the articles. Objects or articles having the same reference are stored adjacent to each other on the upper side of one or several freely moving continuous conveyor belts, the conveyor belt(s) forming the receiving surface for one of the different bays of a storage tray. The conveyor belts are selectively motorized, causing the articles carried by the conveyor belts to be moved in the direction of a point of removal. The selective motorization is obtained by operating moving wheels mounted on a mobile extractor, which is movable in front of the storage rack and transports the conveyor belt(s) of the bay holding the selected or ordered articles by friction in such a way that at least the first one of the articles is transferred to a receiving surface of the extractor.

Abstract: The invention concerns a method for adjusting height of a crate or box made of flexible material, having a base and at least four side walls by folding. After the base has been placed in a generally horizontal, a horizontal crease is produced on each side wall, parallel to the base and at a height substantially equal to a top of a stack of objects. At least one oblique crease is produced in each corner of the crate, with one end located at the intersection between two horizontal creases and the other end located on an upper ridge of one side wall. The upper part of each side wall is folded towards the center of the crate, at an angle substantially equal to 90°. The various flaps are folded on one another, being separated by oblique creases, bringing the upper part of side walls in a substantially horizontal plane.

Abstract: Disclosed is a method for storing and distributing various articles, according to which the objects are stored on the trays of a rack structure. A suitable extraction system driven by a control and command system is movable in front of said rack structure in such a way that said extraction system is aligned in front of the bay of a tray (O2) carrying the stock of articles corresponding to the selected object so as to remove at least one of said articles. Objects or articles (11) having the same reference are stored adjacent to each other on the upper side (13a) of one or several freely moving continuous conveyor belts (13), said conveyor belt(s) forming the receiving surface for one of the different bays of a storage tray. Said conveyor belts (13) are selectively motorized, causing the articles carried by said conveyor belts (13) to be moved in the direction of a point of removal. Said selective motorization is obtained by operating moving wheels (23) mounted on a mobile extractor (3), which is movable in front of said storage rack and transports the conveyor belt(s) (13) of the bay holding the selected or ordered articles by means of friction in such a way that at least the first one of said articles is transferred to a receiving surface of said extractor.
