The arrangement of the center dish and the interior dish is such that it is possible to support and hold, in a functionally safe manner, a pipelines of different diameters with one single support element, while protecting the pipelines from damage due to rock impact and the like.

Abstract: The process and the equipment for reducing emissions of pollutants in flue gases from furnace installations (1, 6) comprises a first furnace installation (1) operated with an air excess of, for example, 15%, and a second furnace installation (6) in which afterburning within the stoichiometric range is carried out, with consumption of the residual oxygen. The flue gases leaving the second furnace installation (6) no longer contain any free oxygen, but contain unburned hydrocarbons, carbon monoxide, nitrogen oxides, sulphur dioxide and sulphur trioxide as pollutants. The first-mentioned pollutants--unburned hydrocarbons, carbon monoxide and nitrogen oxides--are converted on a multi-functional catalyst into carbon dioxide, water vapor and nitrogen. The sulphur of the flue gas is oxidized by means of an oxidation catalyst (12) to sulphur trioxide which reacts with the water vapor contained in the flue gas to give sulphuric acid.

Abstract: The specification discloses a plastic component having a cylindrical connecting portion with a contoured interior space designed for acceptance of a threaded or profiled bolt or stud.

The members are designed to firmly grip the stud or bolt without undergoing permanent deformation or deforming the cylindrical connecting portion.

Abstract: The invention relates to a plastics fastening device for attachment on a threaded bolt. The device comprises a mounting section having a cylindrical aperture in which is disposed a thin-walled cylindrical sleeve connected to an interior wall of the aperture by a plurality of radially extending ribs.
