Abstract: A structural assembly of a cell of an electrolyzer of the staple-type having a plurality of cells stacked in an axial direction, the structural assembly including a main frame having a mounting surface and a seating surface, a pressure frame arrangement and a membrane arrangement abutting against the seating surface and being sandwiched between main frame and pressure frame arrangement in the axial direction. The common axial extension of the membrane arrangement and the pressure frame arrangement in the assembled state is set by the axial distance between the seating surface and the mounting surface and is reached by an axial pressure force applied in the assembly process, whereby the reduction of the common axial extension is predominantly provided by an axial extension reduction of the pressure frame arrangement.

Abstract: An electrolyzer of the cell-stack type, including a first and a second end plate having a plurality of axially stapled cells in-between the cell stack, a manifold for electrolyte flow from an electrolyte inlet in one of the end plates, the manifold having a plurality of diverting portions diverting primarily axial electrolyte flow into electrolyte flow primarily in the radial plane, and further having a bypass directing electrolyte flow to one of the diverting portions bypassing another one of the diverting portions which is axially closer to the electrolyte inlet than the one diverting portion.

Abstract: A fixed bed arrangement formed as an insert for a reactor for catalytic conversion of reaction media, in particular for catalytic methanation of a gas mixture including hydrogen and carbon dioxide, having a receiving chamber, which extends axially within an outer sleeve, and through which reaction media flows during the reactor operation for receiving a catalyst material, and a heat exchanger arrangement having a fluid flow path for a temperature control fluid, which fluid flow path is spatially separated from the receiving chamber, for removing and supplying heat from/to the process. The outer sleeve is formed by the heat exchanger arrangement, at least in regions. The fixed bed arrangement includes a reactor for the catalytic reaction of reaction media having a pressure chamber for receiving reaction media, and such a fixed bed arrangement inserted into the pressure chamber.

Abstract: A computer assisted surgery apparatus includes a surgical instrument having an intervention member to cut tissue of a body part of a patient; a control unit arranged to control position and orientation of the intervention member in relation to the body part with regard to a predefined osteotomic line on the body part; and a tracking device arranged to track a position and orientation of the body part. The surgical instrument includes an optical monitoring system mounted in relation to the intervention member, wherein the optical monitoring system is arranged to continuously detect positions of marks applied to the body part, and the control unit is arranged to adjust position and/or orientation of the intervention member when a predefined deviation of the positions of the marks is detected. The surgery apparatus allows for application of cuts in the body part at comparably complex cutting geometries and at comparably high precision.
