A device for taking a sample from a solid body by cutting out, having a frame and a cutting tool retained on the frame in such a way that the cutting tool can be moved relative to the frame, wherein the cutting tool, at least in parts, at least substantially has the shape of a hollow spherical cap or a hollow spherical segment. A method for taking a sample from a solid body by cutting out is implemented with the device.

By applying material on only one side in the case of a revision, seal rings can be easily rebuilt and reused.

Repaired ring and method for repairing a ring which is used for sealing purposes

A seal arrangement () for sealing an annular gap () between a high-pressure steam space () and an adjacent low-pressure steam space (). The gap is defined between two turbine casings () each split into two casing halves, the seal arrangement () has a seal element () which is formed in a segmented and annular manner and extends between the two turbine casings () and engages in an annular receiving groove () by means of at least one of its radial end regions. The seal arrangement () has at least one segmented ring () with a first circumferential surface () releasably attached to one of the turbine casings () in the region of the annular gap (), and has an opposite second circumferential surface () with the annular receiving groove () or, in a one-piece form, with the radially projecting annular seal element ().
