An apparatus for welding polymeric pipes such as pipe segments in a pipeline welds first and second pipes around a circumferential weld zone and has one or more welding heads, a carriage for guiding the one or more welding heads around the circumferential weld zone and a drive arrangement for effecting relative rotation between the pipes and the or each welding head. The or each of the welding heads has a body and a heating element carried by the body for supplying heat to the circumferential weld zone to cause melting thereof. The heating element is arranged to reciprocate relative to the body of the welding head between a retracted and an extended configuration such that as the heating element moves from the retracted to the extended configuration the heating element melts and penetrates the surface of the circumferential weld zone forming a weld.

Provided are a laser-welded structure and a laser welding method for a cover and a housing ensuring high reliability and suppressing changes in characteristics due to burrs protruding into a subpassage of the flow sensor. To this end, this flow sensor is provided with a housing, a cover, a circuit chamber sealed between these and housing electronic components or wiring, and a subpassage through which the fluid flows that is to be sensed, and is characterized in that there are projections provided on both ends of the joining section of the cover where the housing and the cover are laser-welded, and the height of the projection on the subpassage side is greater than the height of the projection on the side opposite of the subpassage.

A wind turbine blade includes a first shell member including a first mating surface along a first edge of the wind turbine blade. Also, the wind turbine blade includes a second shell member including a second mating surface along the first edge of the wind turbine blade, wherein the second mating surface is opposite to the first mating surface. Further, the wind turbine blade includes a bonding material disposed between the first mating surface and the second mating surface and configured to bond the first mating surface to the second mating surface. Moreover, the wind turbine blade includes a constrainer positioned at a desired bond line and coupled to one of the first mating surface and the second mating surface, wherein the constrainer is configured to restrict the bonding material from migrating into an interior cavity of the wind turbine blade.

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.

A method and manufacturing unit for producing a rotor blade (5) of a wind turbine (1) from at least a first rotor blade element (11, 11, 12, 12) and a second rotor blade element (11, 11, 12, 12). The first rotor blade element (11, 11, 12, 12) and the second rotor blade element (11, 11, 12, 12) are positioned in the desired relative arrangement with respect to each other such that a joint gap (13) remains between the first rotor blade element (11, 11, 12, 12) and the second rotor blade element (11, 11, 12, 12). Adhesive is introduced into the joint gap (13) for joining the first rotor blade element (11, 11, 12, 12) and the second rotor blade element (11, 11, 12, 12).

Embodiments disclose a trim part comprising an airbag system for the interior of a motor vehicle. The trim part comprises a carrier, on which an airbag module is disposed. A joint is formed at least in sections between the carrier and the airbag module. A primary connecting element, which includes an adhesive, is disposed within the joint so that the primary connecting element is non-detachably connected both to the carrier and the airbag module. The trim part further comprises at least one secondary connecting element for temporarily fixing the airbag module to the carrier before the non-detachable connection between the carrier and the airbag module is created by the primary connecting element. Embodiments further disclose a method for the production of the trim part.

A method of manufacturing a Coriolis mass flowmeter from a polymeric material is described, in which a dynamically responsive manifold is fabricated from the same material as the flow sensor's flow-sensitive elements. The flowmeter is free of mechanical joints and adhesives. The manifold and flow-sensitive elements therefore do not slip or change their location relative one another, nor are they subject to differing degrees of thermal expansion that would otherwise undermine integrity, reliability, and/or accuracy of the boundary condition at the ends of the vibrating flow-sensitive elements.

A medical device having a permeable bag connected by a non-permeable cannula to a discharge sac is described along with a manufacturing process and surgical implantation method. The permeable portions of the device have pores that are sized to be permeable to a predetermined class of small molecules, such as oxygen, nitrous oxide, or other therapeutic agents. Once absorbed inside the device, the small molecules are then passively transported, by a concentration gradient of the small molecules, to the discharge sac to be disbursed. A metal tube or other strip can be included in the cannula to assist a surgeon in orienting the device within the body.

A synthetic resin-made welding joint that has a pipe end portion into which an end portion of a synthetic resin-made tube is to be fitted and inserted, and that is configured so that the pipe end portion and the tube end portion which is fitted and inserted thereinto are enabled to be welded together by heating of heating means which externally surrounds the pipe end portion, therefore, a synthetic resin-made holder which is fitted and attached onto the pipe end portion is disposed, and a flange for ensuring a radial expansion gap with respect to the heating means is integrally formed in the holder.
