Abstract: A cup-shaped reusable plastic container has an open end which has a sealing edge with a sealing surface, the sealing surface being configured such that the sealing surface is connectable with a first sealing foil. The container jacket has a wall thickness from 0.5 mm to 4.0 mm. The sealing edge has a sealing edge thickness which extends in the axial direction of the longitudinal axis, and the sealing edge thickness is from 0.8 mm and 4.0 mm. The sealing surface is configured such that the sealing surface can be connected to a further sealing foil after removal of the first sealing foil from the sealing surface of the sealing edge, and following cleaning of the reusable plastic container. Also, a method reprocesses a cup-shaped reusable plastic container.

Abstract: The innovative concept described herein relates to a magnetic angle sensor system having a rotatable shaft, a permanent magnet coupled to the rotatable shaft, and a magnetic field sensor arranged opposite the permanent magnet, wherein the magnetic field sensor is configured to detect a magnetic field prevailing in its detection region. The magnetic angle sensor system comprises means for reducing and/or compensating for an inhomogeneous stray field component of a per se homogeneous external magnetic stray field.

Abstract: A corrugated packing grid with consecutively arranged wave crests and wave troughs for a structured packing, which is assembled from several packing grids, for gas-liquid contacting apparatuses, and a packing assembled from the packing grids. The packing grid and the packing have a large mass transfer area and a low pressure drop at the same time and offer a high mechanical strength. This can be achieved in that elements lie in the region of the wave troughs of the packing grid, the elements extending into the wave troughs.

Abstract: The present invention relates to a valve tray for mass transfer columns having a base plate, at least one liquid intake and at least one liquid outlet for forming a liquid flow having a direction of flow on the base plate, a plurality of gas entry orifices formed in the base plate and also a plurality of fixed valves covering the gas entry orifices, which fixed valves are formed in one piece with the base plate and in each case include a valve roof at a distance to the base plate and also a valve rear side and a valve front side, wherein between the base plate, the valve rear side, the valve front side and the valve roof of each fixed valve, at least one side gas outlet orifice is formed in each case. The side gas outlet orifices of the fixed valves can taper in the direction of flow of the liquid flow.

Abstract: The invention relates to a corrugated packing grid with consecutively arranged wave crests and wave troughs for a structured packing, which is assembled from several packing grids, for gas-liquid contacting apparatuses, and to a packing assembled from said packing grids. The aim of the invention is to provide a packing grid and a packing which have a large mass transfer area and a low pressure drop at the same time and which offer a high mechanical strength. According to the invention, this is achieved in that elements lie in the region of the wave troughs of the packing grid, said elements extending into the wave troughs.

Abstract: An ink cartridge for fitting onto a recording head of the type having an ink feed needle, comprising a first ink chamber which contains a first porous and compressible element, and an ink feed nozzle connected to the first ink chamber via at least one passage opening, for the purpose of channelling the ink out of the first ink chamber to the ink feed needle. The ink feed nozzle contains a second porous and compressible element which is engaged by the needle and which is movably arranged in the ink feed nozzle so as to press against the first porous and compressible element when the second element is engaged by the needle.
