It is proposed to assign a mounting arm to a toll calculator which is embodied as a surface-mounted device and which is connected in an articulated fashion to the toll calculator and can be mounted on the windshield of the motor vehicle. The toll calculator itself then rests with a relatively small area on the dashboard of the motor vehicle with the intermediate connection of a preferably elastomer supporting element which is preferably coated with adhesive on two sides.

An apparatus for electropolishing surfaces includes an inner housing having an open side with a rim facing toward a surface to be electropolished and being otherwise closed. A guide apparatus moves the inner housing along the surface to be electropolished. An inner seal is disposed between the rim of the inner housing and the surface to be electropolished. An electrode is retained in the inner housing. An outer housing has an interior in which the inner housing and the electrode are disposed. The outer housing has an open side with a rim facing toward the surface to be electropolished and is otherwise closed. An outer seal is disposed on the rim of the outer housing. Connections are associated with the outer housing for supplying and removing a rinsing fluid to and from the inner housing. Ducts are associated with the outer housing for supplying and removing electrolyte fluid to and from the inner housing. Auxiliary devices are connected to the connections and the ducts for supplying rinsing fluid and electrolyte fluid.

A vertically disposed steam generator includes a pressure vessel containing: a tube plate, chambers, a bundle of U-shaped bent heating tubes with supporting anchors, a steam trap above the heating tubes, and tubes for a secondary medium discharging into the pressure vessel. The heating tubes have ends guided through openings in the tube plate and discharging a primary medium into the chambers. A method and apparatus for renewing the steam generator includes disconnecting the tubes for the secondary medium; dividing the pressure vessel into an upper region forming a steam dome and a middle region with a jacket surrounding the bundle of heating tubes while leaving a lower region having the chambers; successively raising the steam dome, the steam trap and the jacket; disconnecting the heating tubes and the anchors above the tube plate, and raising the entire bundle; removing remaining parts of the heating tubes from the tube plate and preparing free openings for receptacles of new heating tubes; introducing a prefabricated new bundle having new anchors and heating tubes, introducing the ends of the new anchors and heating tubes into the openings of the tube plate and connecting the ends of the new anchors and heating tubes to the tube plate; and replacing the disconnected jacket, the raised steam trap and the disconnected steam dome, and reestablishing the previous connections of the tubes for the secondary medium.

An apparatus for drawing-in a pipe end by plastic cold forming includes a clamping body. An annular body disposed on the clamping body has an inner surface and a center. An internal tool in the form of a stop ring is centrally supported on the clamping body for defining a desired inside pipe profile. A plurality of jaws is disposed on the clamping body for extending over the outside of a region of a pipe to be drawn-in. The annular body has blind bores serving as cylinders formed therein in radial directions with openings facing toward the inner surface of the annular body. Pistons connected to the jaws are inserted in the cylinders and movable radially toward the center of the annular body by a pressure medium. The stop ring has individual stops in the form of stop heads with threaded shafts being radially adjustably screwed into radial threaded bores formed in the stop ring. The threaded shafts may be rotated.

Pipeline vehicle

The shut-off device is a hollow cylinder upon which is disposed a brake for fixing the position of the device in the pipeline and a seal which seals the area between the hollow cylinder and the wall of the pipeline. A valve is positioned in the hollow cylinder which allows flow of the pipeline fluid through the hollow cylinder when open but can be closed to stop the flow of pipeline fluid through the cylinder. The device is movable through the pipeline.
