摘要:
A gasket for the cylinder head of a motor-vehicle engine includes a body including a polymeric matrix containing a reinforcement material including a dispersion of nanofibers or nanotubes of electrically conductive material. Each nanotube or nanofiber has a substantially elongated shape. A uniform distribution of electrodes is associated to the body. Two layers of electrically insulating material are arranged on the top and bottom surfaces of the body, one on top of and one underneath the polymeric matrix, and designed to insulate electrically the dispersion of nanofibers or nanotubes contained therein. Control and processing means are designed to be connected to any pair of electrodes of the distribution for determining any variation of load applied in an axial direction to the gasket.
摘要:
A device for autonomous power supply of power-using devices set in the proximity of a road, along which vehicles travel, includes one or more electric-current generator elements of a piezoelectric type. The device includes at least one structural element configured for being deformable in an elastic way in at least one direction in response to a perturbation of the environment adjacent to the path of a vehicle that is travelling. The at least one structural element includes at least one area of deformation. The electric-current generator element of a piezoelectric type is associated to the area of deformation.

摘要:
A magnetic device for gripping and clamping workpieces, in particular sheet-steel elements (L), comprises a supporting casing (2), slidably mounted within which is a magnet-holder member (4) carrying a main permanent magnet (M). The magnet-holder member (4) can be displaced between an advanced, operative, position, in which the main magnet (M) is designed to grip and clamp a workpiece (L), and a retracted, inoperative, position. The movement of the magnet-holder member (M) is controlled by shape-memory actuator means (A1, A2, B, E).
