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: The invention concerns a machine-tool, in particular a milling machine Including a machine frame; a tool carrier mounted on the machine frame for receiving a tool; a drive device for rotationally driving the tool in the tool carrier about a tool axis; a receiving device (6) mounted on the machine frame (1), for receiving a workpiece (7); a first rotary drive device for generating a first relative angular movement between the tool carrier and the receiving device and a second rotary drive device for generating a second relative angular movement between the tool carrier and the receiving device; a translational drive device for generating a relative translation movement between the tool carrier and the receiving device along three axes; a control device, which is designed in such a way that it enables to control the relative rectilinear movements between the tool carrier and the receiving device and the relative angular movement between the tool carrier and the receiving device substantially at the same time
