An enclosure for an AC to DC adapter has a continuous and apparently seamless exterior surface. The enclosure includes a housing and a cap that are joined by a pair of weld joints. One weld is formed on an interior portion of the enclosure providing strength and one weld joint is formed on the exterior surface providing a seamless appearance for the enclosure.

A method and device for inserting a tongue in an insertion groove in a panel by a device, wherein the method includes: displacing a tongue guiding device in a first direction by displacing a puncher in the first direction, and displacing a tongue between a first part and a second part of the tongue guiding device and into an insertion groove in panel by further displacing the puncher.

An impeller in which a plurality of vanes are provided so as to overlap each other back and forth as viewed in the direction of axis has a first impeller part on a front side and a second impeller part on a rear side. A method for manufacturing impeller includes a step of molding a first impeller part, a step of molding a second impeller part and a step of combining together the first impeller part and the second impeller part.

A golf club head includes a metallic section, a polymeric section, and an adhesive material. The metallic section defines an opening and the polymeric section extends over the opening. The adhesive material is disposed between the metallic section and the polymeric section to form an adhesive joint therebetween. The adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section when the adhesive material is at least partially cured. The metallic section and the polymeric section are also mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section. The adhesive retaining strength of the adhesive joint, alone, is greater than the mechanical retaining strength of the mechanical joint, alone, only when the adhesive material is at least partially cured.

An enclosure for an AC to DC adapter has a continuous and apparently seamless exterior surface. The enclosure includes a housing and a cap that are joined by a pair of weld joints. One weld is formed on an interior portion of the enclosure providing strength and one weld joint is formed on the exterior surface providing a seamless appearance for the enclosure.

A liquid pressure-reducing unit having a first half body with a contact surface and first groove extending over the contact surface is disclosed. The unit has a flexible resilient sealing element having a floor layer lining the floor of the first groove. The unit has a second half body with a contact surface and first and second walls extending out of the contact surface and defining a second groove. The contact surfaces of the first half body and second half body join, wherein the first and second walls penetrate into the first groove so that the free end of the first and second walls forms a fluid-tight contact with the flexible resilient floor layer lining the floor of the first groove, defining a fluid-tight channel bringing in fluid communication a fluid inlet with a fluid outlet. The channel is non-rectilinear and/or having a cross-section varying over the length thereof.

A method of manufacturing a cartridge includes plasma-treating at least a portion of a region of a storage of a cartridge, applying an adhesive to the region of the storage which is plasma-treated, and sealing the storage by coupling a cover to the region of the storage to which the adhesive is applied.

A plastic aerosol container (10), an associated preform (10a) and a method of manufacturing the preform (10a) and container (10) is described. The container (10) comprises an adapter (20) that defines an opening (11) of the container (10), the opening (11) being arranged to receive and be sealed by an aerosol valve cap (3). The container (10) also comprises a body 40 that defines an internal volume of the aerosol container (10). The container (10) is blow-moulded from a preform (10a) ideally having a corresponding adapter (20a) and body (40a) which are secured to one another, with an expansion region (45a, 46a) of the body (40a) of the preform (10a) being arranged to be expanded to form the internal volume of the aerosol container (10).

A frictional weld joint couples first and second body portions of an article together. The frictional weld joint comprises a first bead extending from the first body portion of the article and a second bead extending from the second body portion of the article. The second bead has an interior stem and an exterior stem space from the interior stem defining a cavity therebetween. The first and second beads are placed in contact with each other with the centerline of the second bead offset from the centerline of the first bead. A force is applied to either the first or second body portions to generate friction between the first and second beads to plastically displace the first and second beads. The force is removed for fusing the first and second beads together to couple together the first and the second body portions of the article.

Method for manufacturing a composite work piece for a drug delivery device, comprising the steps: Providing a first work piece part 1 and a second work piece part 2, arranging both work piece parts 1, 2 with respect to each other in such a way that both work piece parts 1, 2 are in mechanical contact with one another in a contact area 3, irradiating a surface of the first work piece part 1 with electromagnetic radiation, thereby softening the first work piece part 1 and/or the second work piece part 2 in a region adjacent to the contact area 3, and joining the first work piece part 1 to the second work piece part 2 in the contact area 3 for the composite work piece. Furthermore, a composite work piece for a drug delivery device is provided.
