Abstract: The invention relates to a damper unit (40) comprising: a hydraulic cylinder (50) having a hydraulic piston (51) movably mounted therein, which hydraulic piston is coupled to a piston rod (70) and divides the hydraulic cylinder (50) into two hydraulic chambers (52, 53) which are fluidically interconnected via at least one hydraulic channel (54); and a pneumatic cylinder (60) having a pneumatic piston (61) movably mounted therein, which pneumatic piston is coupled to the piston rod (70) and divides the pneumatic cylinder (60) into two pneumatic chambers (62, 63) which are fluidically interconnected via at least one pneumatic channel (64); wherein the value of the volume change of the hydraulic chambers (52, 53) during a movement of the hydraulic piston (51) is different and the hydraulic chambers (52, 53) are fluidically coupled to an equalisation volume (80).

Abstract: An orthopedic device has a base and a pivot element which is mounted in an articulated manner on the base. The pivot element is displaceable via a force transmission element connected to a drive from a starting position into a pivoting position that is pivoted in relation to the starting position. The force transmission element permits passive pivoting of the pivot element in the direction of the pivoting position without activation of the drive. A spring element designed for counteracting passive pivoting of the pivot element into the pivoting position is assigned to the pivot element. The spring element is formed separately from the force transmission element, and the force transmission element blocks deformation of the spring element during pivoting by the drive into the respective pivoting position.

Abstract: A gripping device having a chassis, at least one first finger element pivotally mounted on the chassis, at least one drive, and a force transmission element coupling the drive to the first finger element.

Abstract: Various embodiments include an adhesive for the heat-conducting joining of a ceramic substrate, especially of a power-electronic assembly, to a heat sink, and to an assembly composed of a heat sink and a ceramic substrate, made using this adhesive. The use of hybrid metal-organic compounds and/or waterglasses as adhesives produces high degrees of crosslinking and/or the formation of covalent bonds between the adhesive and the bond partners and/or the particles of filler produces a significant increase in the thermal conductivity, so that the thermally conductive layer of adhesive exhibits a greatly reduced thermal conduction resistance relative to the prior art, and so causes less of a load on the heat-removal chain than is normally the case with the conventional methods of joining and/or bonding.

Abstract: An electrochemical cell has at least one plate element which can be cooled by a liquid coolant, such as water. The plate element has a surface that can be wetted for the purpose of cooling with the coolant. The surface of the plate element in the electrochemical cell is configured such that a contact angle between the surface and the liquid coolant is less than 90°. In the method for producing the electrochemical cell an additional method step is carried out which influences the wettable surfaces of plate elements for cooling with coolant and by which a contact angle between the surface and the coolant is decreased.

Abstract: A surface coating for high-grade white and/or gray goods, i.e. items for domestic, sanitary and/or automotive use, in particular housing elements of corresponding devices and machines, as well as decoration, for example those housing elements which specifically have metallic applications and/or elements is disclosed. The surface coating is applied on a metallic or metalized surface structure and has hydrophobic property and/or oleophobic property. The surface coating is defined by a thickness which is less than a structure depth of the surface structure. The height of the surface roughness of the surface structure can thus extend significantly beyond the thickness of the surface coating, so that the surface structure promotes blurring of undesired residues in a kind of intrinsic capillary/channeling effect. Because of the blurring the contour of a soiling is obscured until finally it becomes wholly indistinguishable.

Abstract: A device and method for plasma coating printed circuit boards populated with components are disclosed. A workpiece carrier that is already conventional in electronics manufacturing for holding the printed circuit boards during a plasma coating may be inserted into a sealable chamber, and a plasma coating process may be performed in the chamber, with the printed circuit boards mounted in the workpiece carrier. In this manner, process steps during loading are not only saved, but substantial costs can be avoided, e.g., with respect to the typical cleaning processes.
