Title: Method for finishing pile goods
Inventor: HEIDEMANN GERHARD DIPL CHEM DR
IPC: D06C19/00
Filed: 1985-07-06
Abstract: A method for finishing pile goods, in particular those made from twisted and/or twined yarns is described, which comprises a wet treatment stage, a heat treatment, a pile layer processing stage following this and, if desired, a finishing process, a mechanical treatment being carried out before the first wet treatment stage to align the pile and/or to at least partially untwist tufts. Such a mechanical treatment of the pile goods before the first wet treatment stage prevents the occurrence of pile displacements in the finished goods. As a cause of this, it is regarded that as a result of the wet treatment stage or the heat treatment following this a fixing of tension conditions, different pile layers and/or variably twisted tufts takes place, which are only latently removed in the processing stage of the pile layer. On storage of the finished goods and/or on their use, this latently stabilised condition is ended, for example by a mechanical loading of the pile goods by the action of moisture, which leads to the pile returning to its original position and the pile goods exhibiting the incorrect pile displacements.

Title: Method of renewing linear underground structures accessible by walking or crawling and having a closed profile, in particular sewers, as well as a set of plastic structural elements for realising the method
Inventor: ODOR ISTVAN DIPL ING
IPC: F16L55/165
Filed: 1987-01-14
Abstract: Method of renewing linear underground structures, accessible by walking or crawling and having a closed profile, in the form of underground conduits, in particular sewers, as well as a set of plastic structural elements for carrying out the method. In this method, an inner pipe (lining pipe) is made inside the structure with the use of plastic structural elements, and the hollow space located between the inner pipe and the already existing structure is filled with a subsequently hardening material. In this arrangement, the inner pipe is produced from pipe sections, consisting of plastic structural elements of the same length or essentially the same length and attached to one another by means of connections with groove and rib, in such a way that the adjacent pipe sections are connected to one another by means of plastic sleeves which surround the ends of the pipe sections in a sealed-off manner from outside, are held together and stiffened, and are composed of several parts. The connections with groove and rib can be made here by sealing material, appropriately synthetic-resin cement on a polyester basis, being inserted between the structural elements fitting together. The pipe sections and the sleeves can consist of glass-fibre-reinforced polyester structural elements.
