Abstract: A door hinge comprises a first hinge element fastenable to a door frame and a second hinge element fastenable to a door leaf and includes first and second hinge blade. A first pivot axis is connected, when the door hinge is in a first operating condition, to first and second hinge elements such that the second hinge blade is pivotable relative to the first hinge element, in a first pivot direction, for unblocking a door aperture. The first pivot axis is decoupled from the first or the second hinge element when the door hinge is in a second operating condition. A second pivot axis is connected to the first and second hinge elements such that said first and second hinge elements are pivotable relative to one another, in a second pivot direction which is opposed to the first pivot direction, for unblocking the door aperture.

Abstract: The invention is directed to a process for manufacture of fine precious metal containing particles, specifically silver-based particles and silver-based contact materials via an intermediate silver(+1)-oxide species. The process comprises in a first step the formation of a thermally instable silver (+1)-oxide species by adding a base to an aqueous silver salt solution comprising an organic dispersing agent. Due to the presence of the organic dispersing agent, the resulting silver (+1)-oxide species is thermally instable, thus the species is decomposing to metallic silver at temperature lower than 100° C. The process optionally may comprise the addition of a powdered compound selected from the group of inorganic oxides, metals, and carbon-based compounds. Furthermore the process may contain additional separating and drying steps. The process is versatile, cost efficient and environmentally friendly and is used for the manufacture of silver-based particles and electrical contact materials.
