Device (1) for solidifying a coating layer hot deposited on a wire (108), corresponding installation and method. The device comprises a cooling liquid injection chamber (2) with a liquid inlet (6) and a wire inlet (4), a cooling chamber (8) with a liquid outlet (12) and a wire outlet (10), and a partition (14) arranged between the injection and cooling chambers (2, 8), comprising a wire passage (16). It also has a conduit (22) for separating the wire (108). The partition (14) comprises channels (18) fluidically connecting the injection chamber (2) with the cooling chamber (8) and leading into the center of the wire passage (16) in an eccentric manner and being inclined forming an angle (α) with respect to a longitudinal direction (L). This directs a jet of cooling liquid on the wire (108) in the direction from the injection chamber (2) towards the cooling chamber (8).

A street pole comprising an antenna section with a coaxially mounted antenna around a pole. The antenna section having a length L and comprising at least one of the following features: —suspension with O-rings wherein the O-rings are each mounted at a distance Dr of 0.5*(1−½√2)*L from a respective end of the antenna; —a fix suspension at bottom; —a reduced outer diameter of the pole at at least one end (i.e. top end and/or bottom end) of the antenna; and —one of i) an extruded cable sleeve with opening in circumference over its full length for easy assembling and to spring mount the cable sleeve around the pole, and ii) a grooved pole with specifically shaped grooves for collecting residual particles at preferred locations.

A manufacturing method of a textured and coated electrode wire, comprising: selecting a copper-zinc alloy as a core material, preparing, by means of electroplating/hot-dipping, a metal zinc coating on a surface of the wire material, then performing pre-treatment on the coated electrode wire by means of discontinuous diffusion annealing to obtain a coated electrode wire material having a multi-layer structure of Zn/β-brass & γ-brass/α-brass, and then using multiple cold drawing treatments and a stress-relief annealing treatment to modify the electrode wire and obtain a textured and coated electrode wire material. Compared to conventional copper alloy electrode wires and zinc-coated electrode wires, the material has advantages of a fast cutting speed, low cutting cost, low environmental pollution, etc., wherein the cutting speed increases by 12% or more when compared with copper alloy electrode wire, the wire breakage rate during cutting processes decreases by 30%, and the replacement time interval of an ion-exchange resin filter for cooling water increases by 10%.

A wire material for a canted coil spring includes a core wire composed of a steel having a pearlite structure, a copper plating layer covering the outer peripheral surface of the core wire, the copper plating layer being composed of copper or a copper alloy, and a hard layer disposed adjacent to the outer periphery of the copper plating layer, the hard layer having a higher hardness than the copper plating layer.

A method for coating a pipe, in particular a motor vehicle pipe, wherein a metallic inner tube is used, and wherein the outer surface of the metallic inner tube is provided with at least one metal layer. A bonding layer is thereupon applied to the metal layer. The pipe is then provided with at least one outer layer. The bonding layer is applied via plasma coating.

A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104) reinforcing at least one of the layers (102, 106). The elongated steel element (104) has an elastic and plastic elongation at break that exceeds 4%. The high elongation of the elongated steel element gives an increased ductility to the concrete structure (100).
