摘要:
The invention relates to a device for inspecting flat goods made of polymeric materials with embedded textile strength supports with which the arrangement and the progression of the strength supports in the polymeric material can be determined in a nondestructive manner and without derogating the quality of the flat goods. According to the invention, NMR-MOUSE probes are used for conducting a nuclear magnetic analysis of the flat goods. The NMR-MOUSE probes (9a, 9b, 9c) form a measuring plane on a measuring body (1) on which the flat good (3) is placed, and are arranged in the measuring plane (6) such that they overlap with one another preferably in the direction of the material in which the inspection is conducted.

The invention relates to a medicinal cushion (1), in particular an anti-decubitus cushion, which is in particular multi-cellular. Said cushion is characterised in that it is equipped, at least in the area that comes into contact with the skin (6), with an active membrane (3) based on a skin-compatible matrix (4), into which a molecular sieve is mixed, said sieve being charged with at least one active agent (Z, Z1 Z2). The molecular sieve/active agent adduct (5) releases the active agent when the active membrane comes into contact with the skin (6) in conjunction with the transpiration of the skin. In a particularly advantageous embodiment of the invention, the medicinal cushion is characterised in that the molecular sieve/active agent adduct (5) also contains crystallisation water in such a way that the molecular sieve is partially dehydrated in relation to a sufficient base mol quantity (m) of crystallisation water. The molecular sieve containing the reduced mol quantity (m') of crystallisation water is charged with the active agent (Z, Z1 Z2) in such a way that when the active membrane (3) comes into contact with the skin (6), water is adsorbed and the active ingredient is desorbed, thus increasing the crystallisation water content of the molecular sieve.

The invention relates to a fuel cell (1) comprising at least the following components: a proton-conducting membrane (2) serving as an electrolyte; catalyst layers (3), which cover the membrane (2) on both sides; gas-permeable electrodes provided in the form of an anode (4) and a cathode (5), which rest against the outwardly pointing surface of the catalyst layers (3), and; electrically conductive plates (6), which contact the electrodes in an electrically conductive manner whereby being located close to one another and which, together with the electrodes, delimit gas-conducting channels. The fuel cell also comprises gas connections for supplying hydrogen (H2) on one side and oxygen (O2) on the other. The inventive fuel cell (1) is characterized in that the membrane (2) has a matrix into which a proton-conducting organic-based polymer substance is incorporated.

The invention relates to a fuel cell (1) comprising at least the following components: a proton-conducting polymer membrane (2) acting as the electrolyte, catalyst layers (3) that cover the polymer membrane (2) on both sides, gas-permeable electrodes in the form of an anode (4) and a cathode (5) which rest on a surface of the catalyst layers (3), whereby said surface is directed towards the outside, electroconductive plates (6) which contact the electrodes in an electroconductive manner and at closely adjacent distances and, together with the electrodes, define gas-conducting channels as well as gas supplies for the supply of hydrogen (H2) on the one hand and oxygen (O2) on the other hand. The inventive fuel cell (1) is characterised in that the polymer membrane (2) is a vulcanised caoutchouc mixture on the basis of a halogenated caoutchouc, especially when bromobutyl caoutchouc is used. The invention also relates to advantageous variants of the polymer membrane (2), e.g. when the caoutchouc mixture contains a molecular sieve/acid adduct.

The invention relates to a material for detoxification of blood (4), containing foreign toxic substances (X), comprising at least: one blood-permeable and blood-compatible matrix (2), in particular, in the form of a membrane (1) and a molecular sieve, incorporated in the matrix (2), or produced as a matrix and loaded with a chromatographic solution (Y) at a pH value of 7.5 ± 0.5, in particular in the form of a cationic solution, whereby the chromatographed molecular sieve (3) performs the detoxification of the blood (4). The above material is characterised in that the chromatographed molecular sieve (3) additionally contains water of crystallisation such that the molecular sieve is partially dehydrated in relation to the full molecular amount (m) of water of crystallisation and said molecular sieve with the reduced molecular amount (m') of water of crystallisation is loaded with the chromatographic solution (Y). The invention further relates to an advantageous method for production of the above material.
