The invention relates to a device for injection molding a tubular element from synthetic material, particularly a tube for dispensing pasty product, comprising an outer mold intended to define the external wall of the tubular element, a main insert which, intended to define the internal wall of the tubular element, extends along the axis of the tubular element, the main insert being fixedly connected to the outer mold at a first end during the molding operation and being movable with respect to the outer mold during a demolding operation.

A piston for a brake caliper of a disc brake constructed as a pot which is open at one end, having a longitudinal axis, a wall, and a piston head. The piston is supported in a cylinder of the brake caliper such that it can be moved along the longitudinal direction, and it can be placed against a brake pad in the region of the piston head by an axial contact surface. When the piston is subjected to pressure by a hydraulic fluid, the piston moves in the cylinder and presses the brake pad against a brake disc. A projection having a conical surface is provided on an inner surface of the piston head. A recess is provided, which is substantially at the same distance from the longitudinal axis as the projection on the inner surface of the piston head, on an outer surface of the piston head.

The invention relates to an axle body, particularly for a commercial vehicle, wherein the body is configured substantially as an axle pipe, which comprises a center section and at least one receiving section connected thereto for receiving an axle guide, wherein the axle body in the center section has a substantially constant wall thickness, and wherein the axle body in the receiving section, at least in some regions, has a wall thickness that is greater than the wall thickness of the center section.

A crack-propagation line is separate from a seal joining two shells of a confectionery packaging. The confectionery packaging is opened by separating the packaging along the crack-propagation line such that a portion of at least one of the parts of the confectionery packaging is broken to form an opening through which the packaged confectionery can be removed. Consequently, there is provided a method of forming a confectionery packaging and a method of packaging a confectionery product wherein two shells of a confectionery packaging are sealed together and a crack-propagation line is formed in a portion of at least one of the parts of the confectionery packaging. Suitably, the crack-propagation line extends away from the seal joining the two parts. The confectionery packaging is opened by separating at least one of the parts of the confectionery packaging, leaving the seal substantially unaffected. The additional step of forming a separate crack-propagation line rather than intending the confectionery packaging to be opened by separating the two parts through the seal provides improved opening characteristics.

A method of fabricating a circular-shaped metal structure includes the steps of (a) rotating a pipe around an axis thereof, the pipe being composed of a plastic-workable metal, (b) moving a jig towards the pipe in a direction perpendicular to the axis until the jig makes contact with an outer surface of the pipe, and compressing the jig onto the pipe, (c) moving the jig in a direction in parallel with the axis with the jig being compressed onto the pipe while the pipe is kept rotated, (d) measuring a thickness of a wall of the pipe during the step (c), and (e) adjusting a pressure with which the jig is compressed onto the pipe, in accordance with the thickness measured in the step (d).

The burner, particularly a gas turbine burner, comprises a central fuel supply arrangement (27) and an annular air-duct (17) for supplying combustion air and twisting the blades (19) that are arranged in the annular air-duct. The gas nozzles (21) are provided in the fuel supply arrangement by a gas distributor channel (29). Other gas nozzles (23) are provided in the fuel supply arrangement by another gas distributor channel (31). A gas supply pipe (41) has a gas supply channel (35).
