Abstract: A brazing method connects an assembly made up of a pipe, a component provided with an opening, and a compensation element. The compensation element includes a support section and an insertion section that is arranged between an end of the pipe and the opening of the component. An inside diameter of the compensation element is smaller than a diameter of the opening in the component. The insertion section is inserted into the end of the pipe, and the support section is located between the pipe and the component and rests on the component at the edge of the opening. The compensation element, the pipe, and the component are heated, preferably inductively, in a region of the compensation element to a temperature above the melting temperature of brazing material that is present in the region of the brazing points.

Abstract: Graft polymeric membranes and methods for making graft polymeric membranes have one or more trifluorovinyl aromatic monomers that are radiation graft polymerized to a polymeric base film. The membranes comprise a polymeric base film to which has been graft polymerized substituted ?,?,?-trifluorostyrene and/or ?,?,?-trifluorovinylnaphthylene monomers, which are activated towards graft polymerization. As ion-exchange membranes, the membranes are suitable for use in electrode apparatus, including membrane electrode assemblies in, for example, fuel cells. The membranes can also be crosslinked.
