The invention relates to heat treatment selection system optimal for fatigue strength, including a method of its performing and equipment for realization of such method. The heat treatment method of forgings, particularly yoke type, is characterized in that, the forging, particularly of yoke type, is subjected to austenitizing at 860 °C by 1 hour, followed by quenching in quenching oil at 45°C temperature, tempering at 650 °C by 1,5 hour, followed by air cooling. The device for fatigue testing of forging, particularly of yoke type, comprising a drive directly connected with crankshaft by means of coupling, characterized in that the forcing lever (5) is mounted on the shaft double crank (4), that drives a forcing lever, whereas the forging (7) is fixed from one side to the forcing lever (5), while fastened on the other side.

The gutter assembly unit having bracket (U) of gutter (R) and the cover attachement (M). The bracket (U) is U-shaped, hook-shaped with flanges directed external to the cross section, which web locates the gutter between a rim inwardly bent from the rear wall of the web and the outwardly curved front rim of the bracket (U). The cover attachment (M) is suspended on the curved front rim of the gutter (R). The bracket has attachment grooves (3) on the bottom edge of the flanges in the area behind the lower front bend, directed at a sharp angle (a) downward to the rear and the cover attachment (M) has a front face (4) of a height (H) greater than the height (h) of the bracket (U) and an oblique face (5) bent away from the lower edge in from below the bracket (U) upward. The oblique face is finished with a catch (6) which enters the attachment grooves (3) by elastic deformation of the cover attachement (M).

摘要:
The present invention relates to three-dimensional puzzles with segments capable of changing position in relation to one another, said segments having guides for allowing the movement of movable elements. According to the invention, the movable elements are configured in the form of permanent magnets, wherein the movement of each magnet is limited by its own guide, and each magnet is capable of being positioned in at least one of two end positions, wherein the guides in the movable segments are arranged to allow different magnets to interact with one another and to change position relative to movable elements. Movement of the magnets is provided by both the attraction and the repulsion of different magnets. The technical problem addressed is that of increasing the existing assortment of puzzles having movable segments.
