    摘要: A process for the continuous production of thin-walled, radially closed hollow profiles which are composed of nonferrous metals and have a small cross section comprises supply of a flat strip of the nonferrous metal to a forming apparatus (212) at a first supply speed. The thickness of the strip corresponds to the wall thickness of the hollow profile. The forming apparatus (212) is configured for continuous forming of the flat strip supplied into a shape corresponding to the hollow profile. After forming, two opposite edges of the flat strip rest flush against one another in a contact region. A welding apparatus (216) continuously welds the edges which rest flush against one another by means of a laser which emits light having a wavelength of less than 600 nm. The laser heats a point in a welding region which has a diameter which is less than 20% of the cross-sectional dimension of the hollow profile. The welded hollow profile is taken off from the welding region and taken up in an uptake device (226).

    摘要: A transfer device for transferring flowable material between a first reservoir and a second reservoir is provided having a loading device (106) mounted on a support structure (101). The loading device (106) includes several loading arm sections (103-105) mechanically connected by pivot joints (113,116,118). The transfer device further has a transfer line (122) connecting the first and second reservoir. The transfer line (122) is composed of rigid and flexible transfer line sections (123-126, 133). The flexible transfer line sections connect the rigid transfer line sections. At an upstream end at least one rigid transfer line section branches into several flexible transfer lines, which are fluidly merged into the next rigid transfer line in flow direction.

    摘要: For the production of fibre waveguides mounted in a metal hollow profile, a flat metal strip is supplied to a deforming unit. The deforming unit is configured for continuously deforming the supplied flat metal strip into a shape corresponding to the hollow profile. The hollow profile is continuously welded along a longitudinal seam by means of a laser. A filler gel with a viscosity which increases with decreasing temperature, and one or more fibre waveguides, are introduced into the welded hollow profile in a continuous process via a guide or protective tube. In order to introduce the one or more fibre waveguides with an excess length into the hollow profile, the welded hollow profile is elastically stretched, is cooled, and is relaxed again. The finished product is received in a receiving unit. The continuous closed-loop control of the excess length of the fibre waveguides is performed inter alia through continuous open-loop control of the gel temperature, of the laser power and of the force exerted on the hollow profile for the elastic stretching.

    摘要: A coupling for connecting a first and a second multi-walled line (203,204) having at least two concentric pipes (206,207) has a female coupling part (202) with at least two concentric tubes including an inner and an outer tube (217,218) each connected at one end with one of the concentric pipes (206,207) of the first multi-walled line (204), respectively. The coupling further has a male coupling (201) part having at least two concentric tubes including an inner and an outer tube (210,211) each connected at one end with one of the concentric pipes (206,207) of the second multi-walled line (203). The at least two concentric tubes of the female and/or male coupling parts are compressible and/or expandable in an axial direction to ensure a fluid tight connection between the male and female coupling part is already achieved when the coupling has not yet reached its operation temperature.

    摘要: A method for the continuous production of coaxial cables (224) having a thin-walled, radially closed outer conductor of nonferrous metal comprises supplying a flat strip of the nonferrous metal to a shaping apparatus (212), wherein the thickness of the strip corresponds to the wall thickness of the coaxial cable. The shaping apparatus is configured to continuously shape the supplied flat strip into a form corresponding to the outer conductor of the coaxial cable and around a cable core supplied before the outer conductor is closed. After the shaping, two opposite edges of the flat strip lie flush against one another in a contact region and are continuously welded to one another by a welding apparatus (216) by means of a laser, which radiates light having a wavelength smaller than 600 nm. The laser heats a point in a welding region that has a diameter smaller than 20% of the cross-sectional dimension of the coaxial cable. The welded coaxial cable is drawn off from the welding region and, after introducing a parallel or helical corrugation, is received in a receiving device (226).

    摘要: A method (100) for the continuous production of a thin-walled, perforated metal hollow profile with one or more fibre waveguides mounted therein. The method includes supplying (102) of a flat metal strip at a first supply rate to a deforming device, which continuously deforms the metal strip into a metal hollow profile with a slot running in a longitudinal direction. Two opposite edges of the metal strip deformed into the metal hollow profile that lie flush against one another in a contact region extending in the longitudinal direction of the metal hollow profile are continuously welded to one another (110), drawn off from the welding region and perforated. The method according to the invention comprises furthermore positioning a protective tube reaching into the welded metal hollow profile on the draw-off side to beyond the perforation point and supplying (111) one or more fibre waveguides from one or more fibre unwinders via the protective tube, such that the fibre waveguide or waveguides are introduced into the perforated metal hollow profile from the guide or protective tube downstream of the perforation point in the drawing-off direction. The perforated metal hollow profile with the fibre waveguide or fibre waveguides mounted therein is received in a receiving unit (124).
