Abstract: The presented invention relates to a cell assembly (100) for the controlled guiding of reactive fluids, wherein: the cell assembly (100) comprises a membrane (101), which has a first side and a second side opposite from the first side; on each of the first side and the second side, a catalyst layer (103) and a microporous layer (105) are disposed; the microporous layer (105) and/or the catalyst layer (103) of at least one side is profiled in such a way that the surface roughness of the catalyst layer (103) differs from the surface roughness of the microporous layer (105), so that the catalyst layer (103) and the microporous layer (105) fit together in parts.

Abstract: The present invention relates to a process for making a compound of formula (I) as described herein Formula (I) comprising reducing a compound of formula (II) as described herein with hydrogen in the presence of a palladium catalyst and a solvent wherein the solvent is a polar, aprotic solvent or a C3-C10 alcohol Formula (II). The present invention further relates to a hydrochloride salt and a monohydrochloride salt of the compound of formula (I) as described herein and to a process for making the same Formula (I).

Abstract: The invention relates to a sheet metal contact element which can be inserted into a chamber of an insulating housing and comprises a rear terminal portion for connecting a conductor, a forward contacting portion, and an intermediate locking section with at least one stamped, outwardly protruding locking tab to anchor the contact element in the chamber. When a strong tensile load is applied to prior art contact elements, the locking tabs, which usually are bent slightly outwardly, are deflected toward the interior of the contact element and permanently distorted. Thus, the contact element is no longer kept in the proper axial position, and the damaged contact element must be replaced. This problem is solved by the present invention by providing a reinforcing pin inserted into the inner cavity of the locking portion. The reinforcing pin prevents the locking hook from being deflected into the interior of the contact element when a load is applied.
