A method of fitting an impingement plate (5) to a platform (2) of a guide blade (1) of a gas turbine, the impingement plate (5) being fastened to at least one supporting surface (10) by means of spot welds (7) and then being brazed onto the supporting surface (10) to the platform (2) by means of high-temperature brazing at a brazing gap (9), and the impingement plate (5) having cooling holes (6), characterized in that the impingement plate (5) is prefabricated with recesses (8) and the spot welds (7) are executed at the recesses (8).
2. The method as claimed in claim 1, characterized in that the recesses (8) of the impingement plate (5) are produced by stamping.
3. The method as claimed in claim 2, characterized in that the recesses (8) of the impingement plate (5) are produced by stamping at the same time as the cooling holes (6).
4. The method as claimed in one of claims 1 to 3, characterized in that the impingement plate (5) is produced with recesses (8) which have a diameter (D) of 1 to 3 mm.
5. The method as claimed in one of claims 1 to 3, characterized in that the height (x) of the brazing gap (9) is set to 0.05 to 1 mm.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A multipurpose traction device comprising in combination:
A planar metal plate,
said plate cut in a decorative pattern,
said plate having edges defining a perimeter or perimeters of said plate,
said perimeter=s including both inside contours and outside contours, such that the length of said perimeter=s is increased, thereby increasing the effective amount of edge or edges available to grip the sole of the users footwear; and
a fastener to couple said plate to a surface selected to have its traction enhanced.
2. The multipurpose traction device of claim 1, wherein said external edges including both inside contours and outside contours such that a length of said perimeter=s is increased to more than 25 inches in length.
3. The multipurpose traction device of claim 2, wherein said inside and outside contours include inside corners.
4. The multipurpose traction device of claim 3, wherein said inside corners include inside curves.
5. The multipurpose traction device of claim 4, wherein said inside curves include circular curves with a constant radius of curvature.
6. The multipurpose traction device of claim 4, wherein said inside curves include irregular curves with a variable radius of curvature.
7. The multipurpose traction device of claim 1, wherein one surface of the traction device is attached to a foot platform or any smooth surface.
8. The multipurpose traction device of claim 1, comprising a plurality of traction devices,
said plurality of tractions devices having more than 25 inches of perimeter=s length.
9. The multipurpose traction device of claim 1, wherein one surface of the traction device is attached by adhesive or tape, rivet, screw, bolt, glue, or nail.
10. A sports board traction device, comprising:
A board having a top surface and a bottom surface, the bottom surface being adapted for movement over a surface; and
a single or plurality of traction devices disposed on the top surface of the board, wherein each traction device comprises a planar metal plate, said plate cut in a decorative pattern, said plate having edges defining a perimeter of said plate, said perimeter=s including both inside contours and outside contours, such that the length of said perimeter=s is increased, thereby increasing the effective amount of edge or edges to 25 inches or more available to grip the sole of the users footwear; and a fastener to couple said plate to a surface selected to have its traction enhanced
11. The sports board traction device of claim 10, wherein the board is constructed and configured for movement over snow.
12. The sports board traction device of claim 10, wherein the board is constructed and configured for movement over a hard surface.
13. The sports board traction device of claim 10, wherein the board is constructed and configured for movement over water.
14. The multipurpose traction device mounted on surfaces not requiring traction for the purpose of artistic expression or advertisement.
15. A method of making a metal multipurpose traction device comprising the steps of:
Taking a plate of metal having at least one planar face;
Attaching adhesive to one of the surfaces of the metal plate or sheet;
marking said face of said plate with marks denoting a pattern;
cutting through said plate along said marks to form openings in the shape of said pattern.
16. The method of claim 15, wherein adhesive is attached to the plate or sheet prior to cutting said plate or sheet with a computer controlled laser cutter.
17. The method of claim 15, wherein adhesive is attached to the plate or sheet prior to cutting said plate or sheet with a computer controlled water jet.
18. The method of claim 15, wherein adhesive is attached to the plate or sheet prior to cutting said plate or sheet with a computer controlled plasma torch.
19. The method of claim 15, wherein adhesive is attached to the plate or sheet prior to cutting said plate or sheet with a punch and die.
