Abstract: The invention relates to an article having a main body with elastic characteristics, in particular an air spring bellows, a metal-rubber element or a vibration damper. The article has a single-layer or multilayer main body having elastic properties, wherein the outer layer C has at least two laminas C1/C2 and each lamina is formed from an elastomer mixture, and wherein at least one layer D composed of a weave or loop-formed knit or loop-drawn knit has been embedded into this outer layer. This leads to further optimization of the fire-retardant properties.

Abstract: A method for obtaining highly pure hydrogen from a raw gas begins with heating and/or treating a semipermeable material made of metal or a metal alloy, preferably, conducting an electric current through the semipermeable material at the beginning of the method in order to increase the quantity of hydrogen passing through the material. A device for obtaining highly pure hydrogen from the raw gas includes a semipermeable material which forms a boundary between the interior of a pressure vessel and the outer region of the pressure vessel and which is permeable to hydrogen. The device is designed such that is can be heatable or treatable at least in sections, in particular, by means of electric energy.

Abstract: A power transmission belt (20) having an elastic main body (17) includes a top layer as the belt backing and a bottom section having a power transmission zone. The power transmission zone and/or the top layer has/have a coating (15, 16), characterized in that the coating (15, 16) of the power transmission zone and/or the top layer includes at least the following layer construction: a base coating (18) made of a textile material, wherein the base coating (18) forms a bond with the elastic main body (17) and has a surface coating (19) including at least a mixture A, which contains at least one reactive diluent as per DIN 55945:2007-03. The invention further relates to a method for producing such a power transmission belt. The novel coating concept is applicable in particular in a toothed belt.

Abstract: An article has an elastic main element based on a vulcanizate having a wear-susceptible article surface. The article is primarily a drive belt (8) having a top layer (9) as the belt rear and a substructure (10) having a force transmission zone (13), wherein the force transmission zone and/or the top layer is/are supplied with a textile overlay (15), wherein the textile overlay is in turn additionally prepared with a plastic. The plastic is a bonding agent that is arranged between the main body and the textile overlay (15), wherein the plastic is supplied such that it melts during vulcanization and penetrates into the textile overlay while bonding, connected to a permanent adhesive bond between main body and textile overlay. A cotton fabric is used as the textile overlay (15), for example. The plastic is in the form of a film, for example, particularly in the form of a PE film. The primary purpose of use is the V-belt, ribbed V-belt (8) and the toothed belt.
