    摘要： A spunbonded fabric of nylon 6, bonded by binders such as polyacrylates and polyurethanes, in which the filaments are substantially in the .gamma.-modification in the crystalline regions and the average molecular orientation, produced by attenuation, of the nylon 6 filaments is at most 80% of the theoretically possible orientation. It is an object of the invention to produce spunbonded fabrics of improved properties and to do so more economically, e.g. with higher outputs.

    摘要： A nuclear magnetic resonance tomography apparatus has a magnet assembly with a first surface and a gradient coil assembly with a second surface, with an annular gap between these surfaces. A noise-reduction arrangement for damping the oscillations of the gradient coil assembly and/or for stiffening the gradient coil assembly is disposed in this gap in contact with the first and second surfaces. The noise-reducing arrangement can be composed of one or more components, and has contact surfaces, formed by one or more components, respectively in substantially surface-wide contact with the first and second surfaces of the tomography apparatus.

    摘要： For the production of spunbonded fabrics there is given a process consisting in that monocomponent or bicomponent fibers are spun from multiline longitudinal spinning nozzles mounted in rows on double spinning beams in such a way that the emerging filament rovings overlap over the entire production width, that, before depositing, the filament rovings are cooled by transverse blowing from one side and by sucking-off on their other side freed from spinning vapors, mechanically and/or aerodynamically stretched and deposited to the web.The apparatus described comprises double spinning beams with a length of 800 to 8,000 mm which carry multiline longitudinal spinning nozzles staggered to one another with high hole numbers, with lengths of the individual nozzles from 500 to 700 mm.

    摘要： A process for the production of spunbonded webs by the aerodynamic drawing of filaments or filament rows which are drawn by means of air currents divided into component currents whereby the air current is divided into a conditioning current and a drawing current for the conduction and the drawing of the filaments or filament rows, and into a deposition zone current for the fixation of the web, which is deposited in random texture, in its transportation on the perforated collecting screen, and the deposition zone current being sucked off, together with the spinning space current, in a plurality of zones and being returned to the spinning room as a holding current. An additional spinning room current for balancing out the overall system is introduced into the spinning room. The conditioning current and the drawing current are introduced in solely added air mode and the depositing current and holding current are, respectively, within and without in mostly circulated air mode.
