    摘要: The invention relates to a material wherein the main constituent is PVC for manufacturing pipes to be used for relining underground pipelines by the pipe in a folded condition being drawn into the pipeline and being engaged with the inside surface of the pipeline by temperature increase. By the addition of polymer thermoplastic elastomers which can be mixed with PVC the material has a glass transition temperature ranging from 45.degree. to 75.degree. C. and a ratio (Emod, T=20.degree. C.)/(Emod, T=75.degree. C.)>20. The invention also relates to a method for restoring underground pipes by relining such pipes with a pipe which has been folded after the extrusion.

    摘要: In a window comprising a main frame (1), an intermediate frame (3) hinged at the top of the latter and a sash (7) which is journalled as a pivot sash in the intermediate frame, said intermediate frame (3) is provided with an arresting means (5) in the area of the pivoting axis (2), said arresting means normally being engaged with an associate arresting means (6) in the main frame. The arrest can be disengaged by means of a release handle (9) which is placed on the inner side of the main frame (1), and the window can then serve as an emergency exit, as the intermediate frame (3) with the sash (7) is swung clear of the main frame due to a permanent urging of the intermediate frame in its opening direction.
