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.

An apparatus for joining, in particular laser welding, two components, in particular plastics components, comprisestwo workpiece receptacles (1, 3) for respectively holding the two components (2, 4) to be connected, in each case one bearing element, preferably a bearing plate (7), for each of the workpiece receptacles (1, 3), a clamping drive (SA) for at least one bearing element for feeding and bracing of the two components (2, 4) held in the workpiece receptacles (1, 3) during the joining process, a controller (9) for the clamping drive (SA) and in particular a laser welding device (LS), anda mechanically loose coupling between the clamping drive (SA) and bearing element (7) such that the two workpiece receptacles (1, 3) are tiltable towards one another during feeding and bracing. Also disclosed is a method for operating such a joining apparatus during a joining process of two components (2, 4) held in the workpiece receptacles (1, 3), in particular during a laser welding process.

A positive crankcase ventilation system for an internal combustion engine routes blowby gases into the intake of the engine. Because the blowby gases have about 12% water vapor, during cold-weather operation, the water vapor may freeze in the PCV valve or in the port that couples the PCV duct with the intake manifold. In situations in which the PCV duct is pointing toward the direction of flow of the intake gases, a hood or cap is placed over the end of the tube according to the present disclosure. It can be as simple as a 90-degree elbow or multiple openings in the cap. A centerline of the openings is perpendicular or at an obtuse angle with respect to the direction of flow in the duct so that the intake gases do not directly access the openings and cause freezing in the openings (or ports).

A device for reinforcing, sealing or insulating a structural element in a motor vehicle includes a support having a clip for pre-fixing the device in the structural element. The clip includes a base and two flexible wings arranged on the base. The device furthermore includes an adhesive for adhesively bonding the support in the structural element. The device furthermore includes an insertion element, which can be inserted in such a way into an interspace between the base and the wings of the clip when the device is pre-fixed on the structural element by the clip that the flexible wings are restricted in their freedom of movement.

When a cylinder portion of an innerliner is positioned inside a mouthpiece and when an upper mold and a lower mold are brought together, a projection portion is provided on an outer circumferential member of the lower mold that closes a gap between a section of an upper mold side positioning outer circumferential surface following on from an inner circumferential end of an outer abutting surface and a portion of the innerliner where an inner circumferential surface abuts. As a result, the portion of the innerliner that is thermally deformed is prevented from being displaced radially inward of the mouthpiece along a first annular surface.

An intake system component for an internal combustion engine includes a tubular curved portion extending in a curved manner. The curved portion includes an inner wall located on an inner side of a curve relative to an inner passage. The inner wall is made of a breathable fibrous molded body. A part of the curved portion excluding the inner wall includes a portion having a lower breathability than the inner wall.

A sealed container (1) for beverages, especially pressurised beverages, comprises a cup (2) with an open top (3) and a lip (4) circumscribing the open top, and a sealing lid (5) heat welded to the lip (4). The paperboard lid comprises a micron-sized pressure release aperture (6) providing pressure regulation within the cup when the beverage is disturbed. The container includes a removable transport cap (13) for sealing engagement with the top of the cup (2) having a top panel (14) and a skirt (16) circumscribing the top panel, in which the top panel includes a first annular sealing head (19) configured to abut the sealing lid (5) when the plastic lid is engaged on the top of the cup. 12. A welding machine (33) for sealing the sealing lid (5) to the lip (4) of the cup (5) is also described.

A device for thermally welding workpieces including a heating element and a shielding gas supply is provided. The device includes a heating plate consisting of a thermal insulating material in which a groove is formed, said groove includes a heating element, relative to which a surface of a workpiece to be welded is positioned in close proximity to the heating element. A feed channel for a shielding gas is formed in the heating plate and communicates with the groove via at least one through-channel, and the feed channel for supplying shielding gas can be connected to a shielding gas source via a feed line and a valve. The device may further include an assembly for welding a first and a second workpiece, said assembly includes a first and second movement device for moving the workpieces towards one another.

A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. First an outer preform can be fashioned, then an inner preform molded through a center hole in the bottom of the outer preform, and the preforms connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or same, e.g., PET/PET. To prevent mutual bonding during molding of the second, a non-stick coating can be sprayed on a surface portion of the first preform prior to molding the second. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the preform first molded.

A liquid container for a motor vehicle, having a first half-shell and a second half-shell, the half-shells delimiting a storage volume for accommodating liquid, the first half-shell having a first support layer and a first barrier layer, the second half-shell having a second support layer and a second barrier layer, the first barrier being situated on a side of the first support layer facing the storage volume, and the second barrier layer being situated on a side of the second support layer facing the storage volume.
