Abstract: A thread production system has a workstation with, in each case one after another on a processing path, a melt-spinning device with multiple melt nozzles, a thread inlet section, an inlet godet roller pair located at the end of a thread inlet section, a thread drawing device with two hot godet roller pairs which are arranged on a drawing panel frame of the thread production system, and a one take-up reel. The free godet roller ends of a first hot godet roller pair of the thread drawing device on the processing path protrude into an identical first half space as free godet roller ends of the inlet godet roller pair. Here, a rotational axis of a first godet roller of the inlet godet roller pair on the processing path is oriented at an angle of from 0° to 45° with respect to the longitudinal orientation of the nozzle row.

Abstract: An ultra light, noise reducing composite (1) comprises an acoustically transparent, light weight film (6) between an underlay layer (5) and an air flow resistance layer (4). This composite allows to easily tune the acoustic properties by balancing the absorption and sound transmission behaviour of the composite (1). This air flow resistance layer (4) has an air flow resistance of between 500 Ns/m3 and 10,000 Ns/m3 and an area mass between 200 g/m2 and 3,000 g/m2. The underlay layer (5) has a stiffness value in the range between 100 Pa and 100,000 Pa. The light weight film (6) may consist of a synthetic foil and preferably has a thickness of 0.01 mm.

Abstract: To smooth items of clothing, especially shirts, by an inflatable bag, the item of clothing, especially in a damp state, is placed on the inflatable bag, is pulled taut by the inflation of the bag, and is dried by heat. To this end, the inflatable bag is inflated with heated air, certain areas of the item of clothing drying faster than others however. To supply heat energy in a targeted manner to individual, especially slow-drying areas, the inflatable bag includes heating bodies either supplying additional heat for drying the item of clothing, or all of the heat. Advantageously, the heating bodies are applied to the material of inflatable bag.

Abstract: The invention relates to a covering part with cable channels and a cabled covering part such as a carpet for vehicles, which is provided with several self-closing channels acommodating a cable network. These channels can be formed directly into the spring-elastic part of the covering or can comprise a plastic or foam rubber sleeve slotted on their longitudinal side and lying in the covering part. The inexpensive and simple to manufacture covering part permits an exact leading of the cables, a good protection for the cable network and a simple and quick application and exchange of the cables. The invention further relates to a method for manufacturing such a covering part.

Abstract: A composite structure with sound-insulating and sound-damping effects for use on the interior surfaces of motor vehicles, comprising at least two groups of coatings resting loosely on one another. In particular, the first group consists of a bottom part (2) free to vibrate and provided with coatings (6) or a finish like that used in modern motor vehicle construction. Preferably the applied second group of coatings consists of an insulating coating (8, 9). This insulating coating can be provided with an additional protective layer (7) and/or a textile or textile-like decorative layer (5). According to the invention, insulating coating (8, 9) exhibits anisotropic air flow resistance. This is achieved in simple fashion by a carrier layer (9) with a geometric structure and a plurality of support 15 elements (13).

Abstract: A blood vessel prosthesis and a method of producing such a prosthesis in which single fibers having a sticky surface are sprayed onto a rod to form a tube from which the rod is subsequently removed, the fibers being formed in at least one layer, the fibers being applied to the rod in one or more selected directions and, in one form, the fibers, when stuck together, form a tube into which connective tissue cannot grow, the prosthesis having properties such as radial elastic expansibility, non-kinking and the like adaptable to those of natural arteries and views the tube may also be provided with an inner layer of flexible foil for impermeability or an outer coating to provide a smooth outer surface.

Abstract: A pinch ring for the thread balloon of a spinning machine or twisting machine is substantially a single wire loop forming a spiral or helix. The ring may have overlapping end portions. The degree of overlap and the shape of the overlapping end portions as well as the pitch and the axial clearance between opposite points in the overlapping portions are all critical to the performance of the ring. The pinch ring defined by the invention permits substantially higher production rates without decreasing the rupture strength of the thread and provides a thread with substantially higher strength at standard production speeds.
