A method of making an aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The method has the steps of sealing the valve to the product delivery device and outer container at respective annular welds or other bonds joining the valve to the product delivery and to the outer container. The welds, or other bonds may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes. Suitable welds include spin welds.

A silencer for reducing gas noise in a combustion engine intake system has a tubular casing with a first casing part and a second casing part connected to each other by a weld seam to form an outer casing wall, wherein the weld seam is a part of the outer casing wall. A third part for compensating gas noise is positioned inside the tubular casing. The third part is arranged in the tubular casing such that an annular cavity is formed by the third part and the outer casing wall. A weld flash protrudes from an inner surface of the outer casing wall into the annular cavity and is contained therein. The silencer is produced in a single welding process in which the first and second casing parts are connected to each other to form the outer casing wall and the third part is connected to the tubular casing.

Disclosed is an anti-spillage structure arranged on two components which are connected together by vibration friction welding. The two components include a base plate, the anti-spillage structure is provided with a main welding rib and a material-blocking plate, the main welding rib and the material-blocking plate are arranged on the same component or the main welding rib and the material-blocking plate are respectively arranged on the two components. An auxiliary welding rib is arranged at the top end of the material-blocking plate, when the two components are welded to each other, the base plate, the main welding rib, the material-blocking plate and the auxiliary welding rib enclose a spillage cavity, such that the spillage of the main welding rib generated in the welding process is fully accommodated in the spillage cavity.

The present intake manifold consists of segments including an upper member, a lower member, and a middle member that is interposed between these members to demarcate and form intake passages so that the intake passages are arranged in a straight line, and has first welded portions at which the upper member and the middle member are welded together, and second welded portions at which the middle member and the lower member are welded together. The first welded portions are extended outward from the intake passage formed by the upper member and the middle member, and the second welded portions are extended outward from the intake passage formed by the middle member and the lower member. The middle member is provided with ribs holding the first welded portions and the second welded portions in one piece.

The machine (1) for welding profiled elements comprises: a base frame (2); two retaining members (3, 4) of respective profiled elements (5) made at least partly of plastic and an area to be welded (6), the retaining members (3, 4) being mounted on the base frame (2) and defining a first retaining axis (A) and a second retaining axis (B) forming an angle of welding (7), and along which the profiled elements (5) can be fastened; removal means (8) of material from the profiled elements (5) to make a machining on the area to be welded (6) of the profiled elements (5); heat sealing means (9) mounted on the base frame (2) and adapted to weld the areas to be welded (6) of the profiled elements (5); adjusting means (10) of the angle of welding (7) adapted to move at least one of the retaining members (3, 4) to incline at least one of the first retaining axis (A) and the second retaining axis (B) to change the angle of welding (7); sliding means (11) of the retaining members (3, 4), mounted on the base frame (2) and adapted to move the retaining members (3, 4) in mutual approach or moving away without changing the angle of welding (7).

Provided herein is a spar cap having a profile for guiding and receiving a shear web for wind turbine blade. Particularly, the present disclosure provides a pultruded spar cap having a bond gap feature to maintain a uniform space for distribution of bonding paste between the spar cap and shear web. Also, the spar cap is formed with locating features which guide and receive placement of the shear web.

An enclosure for an electronic device includes a housing having a wall defining a cavity that is configured to receive an electronic assembly therein. The wall includes a distal end having a tongue. A cap is sized to attach to the housing with a corresponding groove that is formed in a perimeter of the cap. A double shear weld joint is formed between the tongue and the groove such that flash from the weld is contained within the enclosure and is not visible on the exterior surface of the enclosure.

The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the insulation holder and the wire connection ring has contact with the joining component.

A unit (10) for the regulation or control of a fluid pressure, having at least one housing section (13, 14) and a switching film (22) connected to the at least one housing section (13, 14) for switching at pressure differentials relative to an ambient pressure acting on the switching film (22), and for the regulation, release or blocking of a flow of the fluid between an inlet (28) and a discharge (30) for the fluid. The switching film (22) is made out of a polymer material having fluorine and carbon, in particular a thermoplastic having fluorine and carbon. In this arrangement, a hole cross-section (40) of the at least one housing section (13, 14) is closed off by the switching film (22).

It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.
