Abstract: A method for determining the placement accuracy of a plurality of electrode sheets, wherein the electrode sheets extend on mutually parallel planes and are stacked on top of one another and form a stack; wherein the placement accuracy describes positions of the edges of all of the electrode sheets relative to one another in the stack; wherein the method is carried out using a measuring device having a two-dimensionally resolving X-ray system with at least one beam source for X-ray radiation and a detector.

Abstract: The invention relates to a method for producing a cathode apparatus (16) for a battery (8), especially of a motor vehicle (2), whereby a cathode strip (20) is provided, whereby a cathode (16a) is cut out of the cathode strip (20), whereby the cathode (16a) is placed between two strip-shaped separator foils (16d), and whereby, in a joint step, the two separator foils (16d) are cut to size in an area that protrudes beyond the cathode (16a), thereby forming appropriate separator foil cutouts (16f), and these two separator foil cutouts (16f) are also joined to each other in this area, especially fused together.

Abstract: A processing device for processing a material with a focused blasting medium, having at least a blasting medium source for generating the blasting medium and a conveying device for the material, or additionally a deflecting means for deflecting the blasting medium emitted by the blasting medium source toward the material; wherein the conveying device is arranged opposite the blasting medium source or the deflecting means in such a way that the material, at least with a region to be processed by the blasting medium, can be processed by the conveying device on a circular path opposite the blasting medium source or the deflecting means, so that the material, when the blasting medium source or the deflecting means is moved, can be processed along the circular path with a constant focus position of the blasting medium. A method for processing a material with a focused blasting medium in a processing device.

Abstract: A method for cutting a continuous battery electrode material in order to produce battery electrodes includes providing a continuous battery electrode material and providing a transport device which is designed to move the continuous battery electrode material in a movement direction from a starting point to an end point over a machining region, wherein the transport device comprises at least two transport units. Additionally, at least one cutting device is provided. The continuous battery electrode material is then machined while being moved in the movement direction by means of the at least one cutting device such that at least one machining step is carried out on the continuous battery electrode material. At least one dimension of at least one of the at least two transport units is smaller than at least one dimension of the continuous battery electrode material at least in one region.

Abstract: A backrest part for a vehicle seat having a seatback frame in which is arranged an upper seatback adjustment device that allows continuous adjustment in the upper region of the backrest part. Provision is made that the upper seatback adjustment device includes at least one surface element that is movably mounted in the seatback frame and at least one elastic impact absorber integrated into the at least one surface element, which are arranged so as to be jointly adjustable opposite to and in a direction of travel (+/?x-direction) with respect to the top section of the seatback frame.

Abstract: A clamping system for fixing in position a stack of electrode foils for the downstream manufacturing of battery cells, including a base plate, a pressure plate, at least two clamping elements and a receiving region for receiving the stack between the base plate and the pressure plate, the clamping elements clamping together the base plate and the pressure plate in a way that enables the electrode foils to be fixed in position in the receiving region, the clamping elements being located in the edge regions of the respective long sides of the plates outside of the receiving region, and/or the base plate and the pressure plate each having a plurality of, however, at least two, attachment points for connecting the clamping system to apparatuses of the downstream battery cell production in that the attachment points of a particular plate are differently embodied in the shape or size thereof.

Abstract: In a method and a device for non-contacting monitoring of the fill state of liquids in an unpressurized liquid container, the fill state and/or the fill state change is determined by radiating light onto the boundary region of the liquid at which a fill state-dependent curvature arises due to adhesion forces of the liquid at the reservoir wall and surface tension, and the intensity of the reflected light or the reflection angle is measured at a predetermined location.
