Abstract: The invention relates to a connector for works at height, rescue or mountaineering, including climbing, in which an electronic component is present on the closing screwgate, such as an integrated circuit of the radio-frequency type, usable for the identification via computer systems and in which information relating to the connector itself and its use can be written.

Abstract: The present invention relates to an automatic system suitable for reducing the speed of rotation of one or more suspended loads, preferably where said rotation is originated by the flow tube located downstream preferably of the blades of the helicopter whereto said loads are attached, or by any other cause, and whose mechanical operation is based on the use of at least one aerodynamic surface, which automatically positions so as to exert, through the actual interaction with this flow tube, an aerodynamic moment, with respect to the center of mass of these suspended loads, appropriately contrary to said speed of rotation, so as to determine the slowing and therefore the progressive stabilization thereof. The automation of this deceleration is obtained through the use of a cycle of automatic control which is based primarily on the interaction, obtained with a processor, between an element responsive to said speed of rotation and an actuator capable of rotating said aerodynamic surface.

Abstract: A shackle or clevis for hooking to the link of a chain, of the type comprising an external support half-ring formed by an arch of the half-ring and by two legs of the half-ring which originate from the opposite ends of said arch, each of the two legs having the terminal end widened and provided with a transverse hole which, in the position of closure of the shackle, is aligned with the transverse hole of the other one; and a bolt, possibly unlosable, slidingly supported in the hole of a leg so as to be inserted in the hole of the other leg, provided with means for locking dosure of the shackle; said shackle also comprises inside the support half-ring a fork which can be inserted on a diameter of the two straight sides of the link of chain to be hooked and which can be clamped between the links chained to said chain link to be hooked, said fork having each leg integral with and parallel to a corresponding leg of the support half-ring and mouth lying on the side of the bolt.

Abstract: A connector with snap closure comprises a pair of levers elastically stressed, each lever having a formed end for performing the closure for the connector, and the other formed end for providing a snap element and an element for manual control of opening of the connector.
