A steel wire netting (100, 200) is adapted to be used in erosion control, in geotechnical solutions, in rockfall protection or in aquaculture. The steel wire netting (100, 200) comprises steel wires (300). These steel wires (300) have a steel core (302). The steel core (302) is of a low-carbon or high-carbon nature. The steel wires (300) further have an intermediate metallic coating (306) of zinc or an zinc aluminium alloy or a zinc aluminium magnesium alloy on the steel core (302). The steel wires (300) further have a top coating of a polymer (310). This polymer (310) is a high density polyethylene.

A wire shaping tool and method of using the tool to reshape wire, including the discrete sections of wire in a wire mesh panel, is provided. The tool includes a pair of levers joined at a fulcrum positioned closer to one end of the levers, a pair of jaws on one side of the fulcrum, and a pair of handles on the other side. The first jaw can include an elongate body with a concave surface having a pair of opposing lateral edges. The second jaw can include a complementary convex surface configured to converge toward contacting the concave surface of the first jaw. The concave and complementary convex surfaces can transform the shape of a wire positioned between the jaws when they are actuated. The second jaw can include a third shaping component that allows for the simultaneous reshaping of two adjacent wire sections in a wire mesh panel.

A panel system for the containment of landslides caused by partial collapses and also by “rock breakdowns”, for use in the fortification of mining tunnels, hillsides and roads, together with anchor bolts and plates, comprising a network constituted by straps of metal or other material resistant to traction or with the capacity of tearing along the strap (1) (2) (3), with each node of this network firmly linked with a buckle (6) (7) (8) (16) and with a frame (20) attached to this network, where the frame comprises flat tendons (17) near the perimeter of the panel, linked to plates with lugs (D11) or with flat connectors (12) (13) (14) (15) which go beneath the normal plates.

An organic light-emitting device having a low driving voltage, high efficiency, and a long lifespan is provided. The device includes a first electrode, a second electrode, and an organic layer between the first electrode and the second electrode, wherein the organic layer includes an emission layer, a first compound, and a second compound. Various chemical structures for the first compound and the second compound are provided.

The invention relates to a structure for the reinforcement of pavements. The structure is provided at predetermined positions with interruptions or with weakened zones. The invention further relates to a method of manufacturing such a structure and to a method of breaking up a pavement reinforced with such a structure.

A machine (1) for forming knotted fence mesh has a plurality of side by side knot boxes (6). Each knot box (6) is for forming a knot at an intersection between a line-wire (2) and a stay-wire (4). Each of the knot boxes (6) has a first pair of formers configured to move towards the line-wire-stay-wire intersection from a front side forming a knot at the line-wire-stay-wire intersection at each operation of the knot box (6), and a second pair of formers configured to move towards the line-wire-stay-wire intersection from a rear side at each operation of the knot box (6). The machine has a cam drive system configured to move a plurality of the first pair of formers and the second pair of formers at each operation of the knot boxes (6). The cam drive system has a front cam assembly having a front pair of cams (20, 21) associated with the first pair of formers and a rear cam assembly having a rear pair of cams (17, 18) associated with the second pair of formers, wherein each of the cams (17, 18, 20, 21) has a respective profile. The profiles of each of the front pair of cams (20, 21) associated are configured such that during a sector of a rotation of the front pair of cams (20, 21) associated, one of the first pair of formers accelerates while the other of the first pair of formers simultaneously decelerates.

A metal net having entwined metal wires defining the meshes of the metal net comprises at least one elongate sensor element fixed integrally to the metal net, inserted into the net during the production thereof. The elongate sensor element may comprise a wire of a material having a low coefficient of variation of the resistivity and a high gauge factor, preferably formed from constantan, or else may be of the optical fibre or composite fibre type.

A safety net, in particular for catching heavy loads, preferably dynamic impact bodies, in particular rocks, is formed at least to a large extent by mutually engaging net elements, and a maximum overall extension of the safety net parallel to a main extension direction of the safety net is substantially greater in an exterior region of the safety net, which in particular includes at least one outermost row of net elements, than a minimum overall extension of the safety net parallel to the main extension direction in an interior region of the safety net which differs from the exterior region.
