Herein a metallic tube portion is disclosed. The metallic tube portion comprises a connection element. The connection element comprises a protruding portion of a metallic outer tube of the metallic tube portion and a housing member. The housing member is welded to the protruding portion and at least a further portion of the metallic outer tube and/or a portion of a metallic inner tube. A signal line extends at least partially through the connection element.

A method of assembling an electric power steering assembly includes providing a shaft that extends along a longitudinal axis between a first shaft end and a second shaft end. The method further includes extruding or drawing the shaft through a die to define a spline that extends between the first shaft end and the second shaft end. The spline includes a first tooth having a first tip. The method still further includes applying a sleeve over a portion of the spline, such that the sleeve extends from the second shaft end towards the first shaft end.

A heat transfer tube including an inner surface including a plurality of grooves. The plurality of grooves includes at least primary grooves and secondary grooves, wherein the primary grooves extend axially along a length of the tube, and the secondary grooves intersect the primary grooves.

Metal is extruded through a feeder plate and an extrusion die to form a heat pipe component that includes a length of pipe and a flange extending outward from the pipe along the length of the pipe. A section of the flange is removed from the extruded heat pipe component, the pipe is sealed and compressed to reduce its thickness and form a heat pipe element for a computing system.

The invention relates to a method and a device for producing a circular-cylindrical body (4) which consists of a plastic compound and which has at least one helical inner recess that runs in the interior of the body. The method has the following steps: producing a circular-cylindrical body (4), which consists of a plastic compound and which has at least one linear inner recess that runs in the interior of the body, by means of an extrusion molding die (1), discharging the circular-cylindrical body (4) out of the extrusion molding die (1) via a twisting section (7) onto a holding and transporting device (2) which is designed to hold and transport the circular-cylindrical body (4) and which can be rotated about the longitudinal axis of the holding and transporting device, twisting the circular-cylindrical body (4) on the twisting section (7) in order to form the at least one helical inner recess by rotating the holding and transporting device (2) together with the circular-cylindrical body being held and transported in the holding and transporting device, and discharging the circular-cylindrical body (4), which has at least one helical inner recess running in the interior of the body, out of the holding and transporting device (2) onto a storage device (3).

Method for manufacturing a tube of metal in which sensors are attached to tubes, which register and signal a damage of the tube. It is detrimental that protection of the sensors at these tubes against environmental influences is complex. In contrast, it is an object of the present disclosure to provide a method for manufacturing a tube, in which the signal line can be protectively mounted. To solve this object, a method for manufacturing a tube of metal is suggested with an outer tube and an inner tube, wherein a groove is drawn in an inner surface of the outer tube or in an outer surface of the inner tube and subsequently the inner tube and the outer tube are drawn together through a drawing die, wherein the inner dimension of the outer tube is reduced such that after the drawing the outer tube is force-fitted onto the inner tube.

A heat transfer tube including an inner surface including a plurality of grooves. The plurality of grooves includes at least primary grooves and secondary grooves, wherein the primary grooves extend axially along a length of the tube, and the secondary grooves intersect the primary grooves.

A sticker for spacing wood is extruded from an aluminum alloy. The sticker can have different configurations. In a first configuration, the sticker has a width about the same as its height, with longitudinal ridges on all sides that grip wood when wood is stacked on the sticker. In a second configuration, the sticker has a width significantly greater than its height, with longitudinal ridges on the top and bottom surfaces, and with smooth side surfaces. The longitudinal ridges have a height within a specified range and are spaced at a distance peak-to-peak within a specified range. The ridges provide good grip of lumber stacked on the sticker yet do not easily plug with wood fibers through repeated use. The extruded aluminum sticker is very rugged and can be used for hundreds or even thousands of drying cycles.
