A method, apparatus, and design of a fusion welded pipe wherein the effects of an inner bead of the fusion weld are minimized. The internal shape of the pipe prior to welding may be configured in several different shapes so that the beads or lips produced by the fusion welding process are unobtrusive and do not interfere with the function of the pipe. In a likewise manner, the outer shape of the pipe prior to welding may be configured so that the lips are unobtrusive on the external surface of the pipe.

A manually operated floor grooving tool is provided which has opposing front and rear ends with a seam-following roller at its front end and a groove-following roller at its rear end. The tool also employs a pair of grooving blades, one at the front end and one at the rear end. The front grooving blade is inclined upwardly and rearwardly with its cutting tip located just behind the forward axis of rotation of the seam-following guide. The rear-end grooving blade, on the other hand, projects rearwardly from the rear end of the tool and is inclined upwardly and forwardly and behind the groove-following roller. The front-end grooving blade is utilized to form a groove along abutting sections of flooring with the seam-following guide following the seam between the abutting sections and with the groove-following guide traveling in the groove formed by the front-end grooving blade. At a vertical abutment, such as a wall or a cabinet, the orientation of the tool is reversed so that the rear-end grooving blade is directed toward the vertical abutment. Since the rear-end grooving blade projects beyond the end of the tool in which it is secured, it can complete the formation of the groove all the way up to the vertical abutment. The groove is thereafter filled with sealant in a conventional manner. The tool and blades of the invention can also be utilized to create curved grooves in a flooring surface which are later filled with sealant to form decorative patterns.

A blade shell part for a wind turbine blade and a wind turbine blade are disclosed. The blade shell part is made of a composite structure comprising a reinforcement material embedded in a polymer matrix, the blade shell part extending from a tip end to a root end, wherein the blade shell part comprises: a blade shell body with a leading edge and a trailing edge, and a first glue flange extending from the leading edge and having a first glue flange edge and a first glue surface with a first width, wherein the first glue flange is provided with one or more spacer elements. Further, a method of manufacturing a wind turbine blade is described.

A method and a device for connecting a plastic line part in a plastic socket. A head end (9) of the line part (6) is heated contactlessly all the way round until the end curls over to a diameter that is greater than the inside diameter of the socket (5). The line part is then pushed into the socket without using a mandrel or insert, so that the head end (9) forms a liquid-tight fused connection of high tensile strength with molten wall material of the socket (5).

By attaching a socket to an end of one pipe to be connected, attaching a plug to an end of other pipe and inserting the plug into the socket, the both members are constituted to fit to connect. An inner periphery of the socket is provided with a seal ring 50 for sealing an interval between the inner periphery of the socket and an outer periphery of the plug in airtight and a hold ring 49 for restricting movement of the seal ring 50 in an axial direction. The hold ring 49 includes a groove 81 in a ring-like shape for constituting a burr storing space at an outer periphery thereof and is welded to the inner periphery of the socket by ultrasonic welding.

In a plastic fuel tank comprising a main body having a laminated structure including a layer made of gasoline barrier material and an outer layer made of common plastic material, and a component part adapted to be secured in a hole formed in the tank main body, the component part includes at least a part made of weldable plastic material and welded to a part of the tank main body made of common plastic material, and a part made of gasoline barrier material and extending across said component part so as to separate the interior and exterior of the tank main body from each other. The two parts of the component part may be permanently integral to each other or may be detachably attached to each other. Thus, the welding strength can be ensured while the permeation of HC through the part made of the common plastic material can be avoided.

The present disclosure relates to a fluid connector having a sleeve-like connection piece with a connection-piece inner wall and an annular stop collar formed in the interior of the sleeve-like connection piece, said stop collar having an axially directed stop face, and a plastics tube which has a tube inner wall, a tube outer wall and a tube front face. The tube front face of the plastics tube comes into contact with the axially directed stop face. The tube outer wall of the plastics tube is connected to the connection-piece inner wall of the sleeve-like connection piece by means of a friction-welded connection.
