    摘要： A weighing system that works on the principle of electromagnetic force compensation. The weighing system has two guide members (4′), which connect a load support (5′) to a base region fixed to the housing. The weighing system also has at least one transmission lever (6′), which is mounted on the base region. The base region is divided into two separate subregions (2′, 3′), the transmission lever (6′) extends between these two subregions. Two weighing systems are arranged laterally side by side and their base regions are interconnected in such a way that the two subregions (2, 3) of the base region of the one weighing system are connected to the two subregions (2′, 3′) of the base region of the other weighing system such that their positions are fixed relative to each other.

    摘要： Membrane holder for membrane adsorber chromatography comprising a housing body (12) with a reception space for at least one layer of adsorber membranes (22) and at least one first housing cap (34) for closing a first reception space opening, which can be fixed to the housing body (12), a liquid stream being introducible via first liquid guide means (36) through the first housing cap (34) and the first reception opening into the reception opening, so that it passes through the adsorber membranes (22) and flows away through a second reception space opening. The first housing cap (34) can be screwed as a first union nut onto the housing body (12) and a first brace element (24), which can be clamped between the first cap (34) and the housing body (12) via a flange (32) extending beyond the first reception space opening, can be fixed leaktightly in a basket-like insert (14) with a liquid-tight wall and a perforated bottom (18), which is used to receive the adsorber membranes (22). The outer contour of the basket-like insert (14) being fitted in a leaktight fashion onto an inner contour of the reception space.

    摘要： A membrane for fuel cells, which is characterized by a homogeneous absorption and good retention of doping agents, and which guarantees a high mechanical stability at high temperatures when doped. Such membranes consist of at least one polymer, whose nitrogen atoms are chemically bonded to a central atom of a derivative of a polybasic inorganic oxo acid. The membranes are produced from polymer solutions that are devoid of water and oxo acid derivatives, by heating the solution that has been introduced into a membrane mold until a self-supporting membrane has been formed and then by thermally regulating the latter. Inventive fuel cells having a membrane electrode assembly (MEA) that comprises a membrane of the invention and phosphoric acid as the doping agent have, for example, an impedance of 0.5-1 Ωcm2 at a measuring frequency of 1000 Hz and at an operating temperature of 160° C. and a gas flow for hydrogen of 170 mL/min and for air of 570 mL/min. They can be used as high-temperature polyelectrolyte membrane fuel cells for a working temperature of up to at least 250° C.

    摘要： A force sensor with two force input elements to which the force to be measured and the support force are applied. The two force input elements are substantially rotationally symmetrical and are axially spaced apart, and the force to be measured and the support force are applied in a radial direction. A spring element, arranged axially between the two force input elements connects these elements and its load-dependent deformation is converted into an electrical signal. A substantially tubular cover connected to one of the two force input elements surrounds the spring element. The cover surrounds a portion of the other force input element, forming a circumferential gap. The cover has an inwardly projecting constriction that is spaced apart by a small axial distance from an opposite shoulder on the other force input element.
