A hot water storage device having a vessel includes a first section formed from a molded material and a second section formed from a molded material. An open end of the first section is sealingly engaged with an opposing open end of the second section to form the vessel. The first and second sections each have a generally cylindrical body portion and a closed end, comprising a head portion. The vessel includes a water inlet aperture molded into the first or second section and a water outlet aperture molded into the first or second section and wherein the inlet and outlet apertures are located on the body portion proximal to a tangent line between the body portion and the head portion.

The invention relates to a molded product made of fiber material with a connection element (11). In order to achieve a particularly firm anchoring of the connection element (11) in the fiber material of the molded product, the connection element (11) has a connecting wall (17) with holes (18) through which the fiber material of the molded product projects.

A fastening structure is fastened to an object. The fastening structure includes a carbon fiber-reinforced resin, a metal collar and a fastener. The outer circumference of a metal collar has a tapered portion, which is inclined with respect to the central axis of the collar. The inner circumferential surface of a through hole in a carbon fiber-reinforced resin (CFRP) material has an abutting portion that contacts the tapered portion of the collar via an electrically insulating adhesive. The tilt angle of the tapered portion of the collar and of the abutting portion of the CFRP material are the same as the angle at which the displacement of the CFRP material in a direction perpendicular to the surface of the abutting portion due to thermal deformation resulting from temperature changes is balanced with the displacement of the collar in a direction perpendicular to the surface of the tapered portion.

A method for joining primary and secondary members includes providing a primary member, a secondary member and a heating element which is joined to one of the primary and secondary members. The heating element includes an electrically insulating matrix material and an electrically conductive reinforcing clement extending through the matrix material. The method further includes bringing the other of the primary and secondary members and the heating element into engagement and controlling a flow of electrical current in the reinforcing element so as to resistively heat and fuse at least some of the matrix material of the heating element with a matrix material of the other of the primary and secondary members. The method may be used to join a primary member such as a composite tubular and a secondary member such as a component for terminating the composite tubular.

A welding head comprises a welding element (51) for welding a lid (1) to an opening device of a container (10). The welding head (43) further comprises a 5 compensating device (62) operable for compensating a misalignment between the welding element (51) and the lid (1), thereby centering the welding element (51) relative to the lid (1).

An adaptor for anchoring a second object with respect to a first object includes an anchoring part and an adjustment part. The anchoring part includes a distally facing anchoring surface and a proximally facing first control surface, and the adjustment part includes a distally facing second control surface positioned to abut against the first control surface. The anchoring part and the adjustment part define a common axis, and the first control surface or the second control surface or both is/are helical with respect to the axis, whereby a relative z position of the adjustment part with respect to the anchoring part is adjustable by rotating the adjustment part relative to the anchoring part around the axis while the second control surface abuts against the first control surface.

An apparatus for capping a container (10) comprises: a conveying device for conveying the container (10) along a path; an applying head (23) for applying a lid (1) onto a neck (9) included in an opening device of the container (10); a welding head (43) arranged downstream of the applying head (23), the welding head (43) comprising a welding element (51) for welding the lid (1) to the opening device.

A method of applying a lid (1) onto a neck (9) of a container (10), the lid (1) having a side wall (3) extending around an axis and an end wall (2) extending transversely to said axis, comprises the following steps: positioning the lid (1) onto the neck (9); exerting on the end wall (2) a force directed towards the container (10), so as to level the lid (1) on the neck (9); screwing the lid (1) onto the neck (9) by rotating the lid (1) in a screwing direction.

A water valve, guide tube for a water valve, and associated method are provided. The water valve includes a housing and the guide tube is installed on the housing via laser welding. The guide tube and housing each provide axially facing mating surfaces which abut one another in a pre-bonded configuration. In a post-bonded configuration, a laser weld joint is formed at the interface between the mating surfaces. The joint forms a portion of an outer periphery of the housing.

The invention relates to a fuel tank of thermoplastic polymer for a motor vehicle, having at least one reinforcing element inside the fuel tank, the reinforcing element inside the fuel tank extending between opposing tank walls (15), parts of the reinforcing element passing through the tank wall and parts of the reinforcing element engaging behind the tank wall from outside, the fuel tank being distinguished according to the invention in that the reinforcing element (8) is provided with at least one multipart fastening head (11), which comprises a first closing means engaging through the tank wall (15) from inside and a second closing means engaging through the tank wall (15) from outside, which closing means are of mutually complementary construction.
