  • Patent number: 11536127
    Abstract: An apparatus and method for planning a drilling sequence. The solution relates also to a rock drilling rig and to a computer program product. The apparatus searches several possible drilling scenarios for drilling a given drilling pattern. Different actions required by the scenarios have given costs and the executed algorithm calculates total costs of found scenarios. Scenarios with the lowest costs are selected.

  • Patent number: 11534799
    Abstract: Screening media for screening material includes a main body and a plurality of openings extending through the main body between a contact face and back face. The openings are of a shape of a convex and non-regular polygon, and are arranged in an orientation such that a line through the most proximal vertex of the polygon and parallel to a defined material flow direction divides the most proximal interior angle of the polygon. Such a configuration allows the openings to not easily get pegged and to improve screening performance.

  • Patent number: 11524345
    Abstract: A bore cutting tool for cutting metal workpieces includes a tool substrate and a tool coating on a surface of the tool substrate. The bore cutting tool includes a plurality of pits in the surface of the tool substrate and wherein the tool coating extends over the pits such that the pit surface includes the tool coating. In this way, the pit dimensions can be retained over prolonged tool life and the pits, with their coated surface, are particularly effective at retaining lubricant so that the thickness of a lubricant film can be increased as compared to a tool without the coated pits. In the embodiments, the pits are formed by laser etching and are present only on the cylindrical land. Average pit depth is suitably in the range 8 ?m to 25 ?m, average pit width and pit length is independently selected from 40 ?m to 250 ?m and average pit density may be 20 to 30 pits/mm2.

  • Publication number: 20220339688
    Abstract: A high temperature iron-chromium-aluminium (FeCrAl) alloy tube extending along a longitudinal axis, wherein the tube is formed from a continuous strip of a high temperature FeCrAl alloy and comprises a helical welded seam. The high temperature FeCrAl alloy tube is manufactured by feeding a continuous strip of the high temperature FeCrAl alloy toward a tube shaping station, helically winding the strip such that long edges of the strip abut each other and a rotating tube moving forward in a direction parallel to its longitudinal axis is formed, and continuously joining said abutting long edges together in a welding process directly when the tube is formed, whereby a welded tube comprising a helical welded seam is obtained.

  • Patent number: 11478914
    Abstract: A tool bushing of a breaking hammer, a tool bushing arrangement, a breaking hammer and a method of mounting a tool bushing of a breaking hammer are disclosed. The tool bushing is a sleeve-like piece having a multi-shouldered outer surface with three or more successive cylindrical portions. The cylindrical portions have different diameters that match with corresponding surfaces of a bushing housing when the tool bushing is mounted. Diameters of the bushing and the bushing housing are dimensioned so that friction forces are generated when the bushing is assembled.

  • Patent number: 11400489
    Abstract: Screening media to screen oversized material includes a main body and a plurality of openings extending through the main body between an upward facing contact face and a downward facing bottom face. A textured pattern is provided at the contact face to provide a roughened surface for the partial entrapment of material fines. Such a configuration protects the screen media from aggressive contact with the material to be screened and provides a bedding layer that is maintained by material-on-material attrition during bulk material flow over the media.
