Abstract: An extruded aluminum electrical circuit component carrier on which at least one electrical circuit component is to be mounted. A first side portion and a second side portion include areas for mounting at least one first electrical circuit component part and at least one second electrical circuit component part. An inlet to which an inlet conduit for a cooling liquid can be connected. An outlet to which an outlet conduit for the cooling liquid can be connected. At least one supply passage for the cooling liquid formed through the first side portion. At least one return passage for the cooling liquid formed through the second side portion. The at least one supply passage is connected to the at least one return passage in series.

Abstract: A friction stir welding method and a structural body formed using a friction stir welding method. In particular, a friction stir welding method and a structural body made of an aluminium alloy extruded frame member formed by friction stir welding of a number of extruded frame members. Joining is performed by abutting a first member with a second member by contacting a downwards facing surface of an overlapping portion of a first member which projects above one face of the other member in the lateral direction in and an upwards facing surface of a second member in such manner that the downwards facing surface and the upwards facing surface are in slideable contact before joining and the first and second member are rotatable, and carrying out a friction stir welding to join the members to form a frame structure.

Abstract: The present invention relates to a method of sealing an opening in a tubular body (1), comprising at least one through channel (3) extending in the longitudinal direction of the body, an opening (7) of the channel being formed in respective end surface (5) of the body. The method is characterized in that a sealing plug (15) is inserted in the opening (7) and is positioned far enough into the channel (3) that when a stamping tool (19) with an outer diameter which is greater than the inner diameter of the opening (7) is applied perpendicularly to the end surface (5) and concentrically to the opening (7), the portion of the end surface (5) constituting the periphery of the opening (7) is deformed plastically and is pressed into the channel (3) to form a shoulder (21) outside the sealing plug (15) with an inner diameter which is less than the outer diameter of the sealing plug (15).

Abstract: An interlocking panel, and structures formed therefrom, are described herein. Embodiments of the present invention provide a panel including a protruding end including a receiving member for engaging a complementary engaging member of a first adjacent panel, and a receiving end including two flanges, at least one of the two flanges including an engaging member for engaging a complementary receiving member of a second adjacent panel, one or both of the two flanges configured to flex to allow the complementary receiving member of the second adjacent panel to engage the engaging member.

Abstract: The hydroforming tool of the present invention comprises a pair of upper and lower tool inserts having open axial ends and defining an elongated cavity there between when the tool inserts are forced together. The upper and/or lower tool inserts are composed of segments that are attached to the upper and a lower base plates, by bolts. Retaining elements, such as pins, are introduced into holes in the base plates and continues into cavities formed in the segmented inserts. This prevents the insert segments from moving during the forming operation. In this way the use of base blocks may be omitted. Sometimes the friction force acting between the base plate and segmented inserts, caused by the high pressure applied to the tool surfaces, is sufficient to prevent the separation of the segments, whereby the segments are kept in place without the use of retaining elements.
