Abstract: A double-wall pipe includes a media-conveying inner tube, and a multilayer plastics outer tube with a gas permeation barrier layer. The plastics outer tube includes a significant proportion of polyethylene (PE). The gas permeation barrier layer consists of a compact extruded polyethylene terephthalate (PET) layer having a material thickness of from 0.8 mm to 2 mm or comprises a closed-cell foam made from PET having a material thickness of between 10 mm and 100 mm. A heat insulating layer is arranged in an annular gap between the inner tube and the plastics outer tube.

Abstract: The invention relates to a stable, highly concentrated, aqueous suspension of nanoparticles, particularly of titanium dioxide particles, a method for production, and use of the suspension, e.g. for coating or impregnation, or as an additive in organic or inorganic matrices. The suspension contains a first dispersant based on a polymeric alkoxylate and a second dispersant selected from the group of amino alcohols. The suspension is preferably characterized by the fact that its stability is preserved even during and after vigorous dispersion in an attrition mill and no increase in viscosity occurs. In a preferred embodiment, the viscosity declines by up to 10 to 50% as a function of the milling time. In a further embodiment, the suspension can be dried and subsequently redispersed, without the state of dispersion deteriorating.

Abstract: A delivery device, with a delivery piston (27) which is movable in a pump chamber (31) by means of an actuation device (3) and which, in one delivery direction, removes fluid from a fluid line (35) in a pressure-reducing manner and, in a further and preferably opposite delivery direction, discharges fluid into a further fluid line (37) in a pressure-increasing manner, is characterized in that a valve device (39, 41) is introduced into the respective fluid line (35, 37), each with an opposite mode of action, in such a way that, in the pressure-reducing removal process, the respective valve device (39, 41) opens in one fluid line (35) and closes in the further fluid line (37) and, in the reverse case, in the pressure-increasing discharging process, the respective valve device (39, 41) closes in one fluid line (35) and opens in the further fluid line (37).

Abstract: The disclosure pertains to an interior trim part including a support component and a decorative layer, wherein the support component and the decorative layer respectively include a local weakening along a weakening line that makes it possible to tear open the interior trim part in a controlled fashion when a predefined force is exerted upon the support component, and further including an intermediate layer between the support component and the decorative layer, wherein the intermediate layer is bonded to the decorative layer and includes an intermediate layer weakening that intersects the weakening line.

Abstract: The invention relates to a test system for cooling and/or heating at least one test piece comprising a platform, at least one heating and/or cooling fluid providing means coupled to the platform, at least one position means for reproducibly fixing the relative position of the fluid providing means to the at least one test piece and wherein the at least one position means is connected to the platform, the platform comprising at least one fastening means, in particular two openings for releasable coupling the fluid providing means for an at least temporarily fixing of the relative position of the fluid proving means to the test piece. It also relates to a test method.

Abstract: The invention relates to an interior trim part, in particular for a motor vehicle, comprising a base component, a decorative layer made of leather or a leather-like material, and a spacing layer between the base component and the decorative layer, the spacing layer being made of a material that is softer than the material of the base component. The base component, the decorative layer and the spacing layer each have a localized area of weakened material, which allows the interior trim part to break away in a controlled manner when a predefined amount of force is applied to the base component, wherein, at least in the area of weakened material, an intermediate layer lies between the decorative layer and the spacing layer, which intermediate layer does not have a localized weakened area. The invention further provides a method for producing the interior trim part.
