A guide wire for minimally invasive operations with a distal wire end piece (3, II) connected to a wire main piece (2), wherein the guide wire (I, 10) has, at least in the distal wire end piece (3, II), an inner shaft (4, 14) and at least one protective layer enclosing the inner shaft (4, 14), the inner shaft (4, 14) comprises a first fibre composite material and, at least in the distal wire end piece (3, II), the inner shaft (4, 14) has a plurality of weakened points (8, 18), which are created by mechanical interventions, is characterised in that the weakened points (8, 18) are created by buckling load, bending load and/or breaking load. Correspondingly, for a method for producing a guide wire of this kind it is proposed that the weakened points (8, 18) are created by buckling load, bending load and/or breaking load.

Described are methods and systems for identifying processing locations in composite layups. An optical magnetic marker is magnetically supported by a layup tool at a target position, such that a portion of the marker protrudes above the tool processing surface. When a composite layup is placed onto that surface, the protruding portion extends into the layup at a processing location. When the layup is cured, the marker is permanently embedded into the layup. Separating the cured layup from the tool removes the marker from the tool and allows an additional marker to advance into the target position for processing another layup. The embedded marker or, more specifically, marker's reflective surface is used during optical inspection of the layup surface to precisely determine the processing location. In some examples, the marker is consumed while the layup is processed at that location,

The present invention relates to a method of manufacturing a blade shell member for a wind turbine blade. The method comprising providing a blade mould for the blade shell member and arranging a number of fibre-reinforced layers on a blade moulding surface of the blade mould. A first primer layer is applied on top of the fibre-reinforced layers, at a pre-determined spar cap region. Furthermore, a pre-manufactured spar cap having an upper surface, a lower surface, a first side surface, a second side surface, a first end surface and a second end surface is arranged in the pre-manufactured spar cap on the spar cap region, such that the lower surface of the pre-manufactured spar cap contacts the first primer layer arranged on the spar cap region. A second primer layer is also applied to the upper surface of the pre-manufactured spar cap before the step of infusing the blade moulding cavity with resin and curing it. The present invention further relates to a method of manufacturing a wind turbine blade, comprising the steps of manufacturing a pressure side shell half and a suction side shell half over substantially the entire length of the wind turbine blade and subsequently closing and joining the shell halves for obtaining a closed shell.

A reinforcing structure for a wind turbine blade is in the form of an elongate stack of layers of pultruded fibrous composite strips supported within a U-shaped channel. The length of each layer is slightly different to create a taper at the ends of the stack; the centre of the stack has five layers, and each end has a single layer. The ends of each layer are chamfered, and the stack is coated with a thin flexible pultruded fibrous composite strip extending the full length of the stack. The reinforcing structure extends along a curved path within the outer shell of the blade. The regions of the outer shell of the blade on either side of the reinforcing structure are filled with structural foam, and the reinforcing structure and the foam are both sandwiched between an inner skin and an outer skin.

Collapsible containers and a method of their manufacture are disclosed herein. The collapsible containers have one or more collapsible wall sections and a stiff upper and lower tier. The wall sections have living hinges and three or more tiers between the hinges. A thermoplastic elastomer layer may join separately made portions of the container together. The containers may be made by molding and overmolding. The containers include inter alia bulk liquid containers, jugs, tubs, baskets, bottles, and food containers. The method of manufacturing includes placing a container component and a matching container body comprising a stiff first tier, a stiff second tier, and a collapsible wall section in a mold; assembling the container body with the container component to close one end of the container body; and overmolding a thermoplastic layer around the container body and the container component.

A method of making a brush includes providing a plurality of first filaments, each having a first end and a second end; bringing the plurality of first filaments into a first predetermined shape such that the first ends are arranged side by side on a common contour; fixedly connecting the first ends so that a first pre-tuft having the first predetermined shape and a connected first end is formed; bringing a second tuft element having a first end and a second end together with the first pre-tuft into a second predetermined shape such that the first end of the second tuft element and the connected first end of the first pre-tuft are arranged side by side on a common contour; fixedly connecting the connected first end of the first pre-tuft and the first end of the at least second tuft element so that a final tuft having the second predetermined shape and a connected end is formed; and attaching the final tuft to a brush body by overmolding the final tuft's connected end with a plastic material.

A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.
