The invention relates to a method for producing a pressure accumulator (1), in particular for accumulating hydrogen in motor vehicles, wherein first of all an inner liner (3) of the pressure reservoir (1) is produced, preferably by means of a plastic blow molding process, wherein subsequently the inner liner (3) is provided, preferably braided, on the outside with a multi-ply reinforcing layer (9) including reinforcement fibers (8), and wherein the reinforcing layer (9) is then impregnated with a resin, preferably an epoxy resin, which, after curing, fixes the position of the reinforcement fibers (8) in the reinforcing layer (9). According to the invention the impregnation takes place from the contact region (K) of the outer surface of the inner liner (3) with the reinforcing layer (9) to the outer region of the reinforcing layer (9).

A tool device for connecting a plastic pipe or composite metal/plastic pipe to a fitting using a sliding sleeve or compression sleeve. The device includes a housing; a flaring device for flaring the ends of the plastic pipe or composite metal/plastic, pipe; a sliding device for sliding the sliding sleeve on or a pressing device for pressing the compression sleeve on; and a mechanically operable drive element. The drive element can be switched to drive the flaring device or to drive the sliding device or pressing device. The flaring device includes a first piston-cylinder unit, whose working piston has a piston axis and which has an inner end and an end oriented away from the tool device. The sliding device or pressing device includes a second piston-cylinder unit, whose working piston has a second piston axis and which has an inner end and an end oriented away from the tool device.

A method for producing a decorated profile body comprises the following steps. In a first step, a profile body substrate is provided. In a second step, a decoration background is applied to the profile body substrate. In a third step, by means of a digital printing process, a decoration finish is applied to the profile body substrate which decoration finish covers the decoration background of the profile body substrate at least in some sections. The decoration finish is applied to the profile body substrate after the applied decoration background, wherein the decoration background and the decoration finish together form a decoration of the profile body substrate. This creates a decorated profile body in which the decoration background has a color composition which is a substantially expanded color space compared to the decoration finish. The decoration finish is printed using a digital printing process having a comparatively limited color space applied according to the CMYK principle. The color composition of the decoration background is selected in such a way that essentially no metamerism effect occurs between the decoration of the decorated profile body and an adjacent reference decoration of a furniture panel, the reference decoration being substantially identical thereto.

A pipe reduction piece (10) made from plastic material, having an interior volume (12) that is provided for being flowed through by a fluid in a predetermined flow direction, wherein the pipe reduction piece (10) is formed from a first section (14) and a second section (16), said sections having interior walls (18, 20) adjoining one another in a flush manner, wherein the interior wall (18) of the first section (14) delimits a first cylindrically configured partial volume (22) of the interior volume (12), and wherein the interior wall (20) of the second section (16) delimits a second partial volume (24) of the interior volume (12), the second partial volume being configured with a decreasing cross-sectional surface in the direction of the first partial volume (22).
摘要:
An assembly for forming an air-guiding element for a motor vehicle, comprising a shell-shaped air-guiding body and a brake lamp. The air-guiding body has an elongated opening which extends through the air-guiding body. To form an air-guiding element, the elongated opening can be closed off at least in regions by a light emitting surface of the brake lamp. By disposing the brake lamp in a predetermined position, the brake lamp is enclosed at least in regions by the air-guiding body. At least one retention element is integrally formed on a retention side of an air-guiding body portion of the air-guiding body. At least one counterpart retention element is integrally formed on a retention side of the brake lamp. The retention element can be retained on the counterpart retention element so as to retain the air-guiding body on the brake lamp in the predetermined brake lamp position. In the connected state of the air-guiding element and the motor vehicle, the air-guiding body portion is arranged below the brake lamp. The retention side of the air-guiding body portion faces toward the retention side of the brake lamp.

The invention relates to an edge trim for pieces of furniture, comprising a meltable layer. In order to improve a generic edge trim such that the same is more versatile and can especially be mounted on a wider selection of surfaces, the molecular structure of the meltable layer contains both polar and non-polar parts.
摘要:
A method and device for the pretreatment of polymer surfaces of components to be painted. At least one polymer surface of at least one component is preheated to a temperature that minimizes condensation on the component when the component is subsequently cleaned inside a pretreatment cell and then treated with an oxidizing flame. The cleaning of the polymer surface as well as the treatment of the polymer surface with an oxidizing flame are performed inside the same pretreatment cell.
