A drive device for erosion tools, having a drive shaft, an electrode holder connected to the drive shaft, an axial drive which works on the drive shaft, a rotational drive which works on the drive shaft as a direct drive in a contactless manner, and a radial bearing. The radial bearing is constructed as a ball track.

Drive device for erosion tools

The invention relates to an extruder system for extruding a fluid with at least one supply device, at least one mixer device and at least one extrusion die. In accordance with the invention at least one device for producing a fluid flow (transport fluid) that completely or partially surrounds the material to be extruded that essentially runs parallel to the outlet direction of the material to be extruded is provided, and whereby the fluid is discharged from the extruder system by suction and/or pressure of the transport fluid flow by means of an expulsion gas. The extruder system allows even product discharge for products well into the nanometer range.

Extruder system for extruding a fluid

A measuring device for quantitative determination of optical characteristic values for detecting photo- and/or electrochemical decomposition reactions taking place on surfaces of photocatalytically active substrates.

Measuring device and method for determining optical characteristic variables for verifying photochemical and electrochemical degradative reactions

The invention relates to a layered system of a component that can be thermally stressed, comprising at least one for expanding the application scope of layered systems and in particular for improving their life cycle. Said layer has at least one first and at least one second material and a mixture profile () that varies at least almost continuously with the layer thickness, without forming a boundary layer between the first and second material.
