Abstract: A touring skibinding (1) comprises a support element (2) which can be fastened to the ski, a bearing element (3) with a skiboot reception (4) which is designed in such a way that the skiboot (5) can be mounted in the skiboot reception (4) such that the skiboot can pivot about a first pivot axis (S1) with respect to the skiboot reception (4) and a convex supporting surface (6) on which the skiboot (5) can roll, the bearing element (3) being connected to the support element (2) so as to be pivotable about a second pivot axis (S2) from an initial state into a pivoted state, wherein the skiboot (5) is moveable from a standing state, in which the skiboot (5) stands on the convex supporting surface (6), into a pulling state, in which the skiboot (5) is at least partially lifted from the convex supporting surface (6), wherein, starting from the standing state, the skiboot (5) is movable on the convex supporting surface (6) in the direction of the pulling state in such a manner that the skiboot (5) rolls on the conve

Abstract: A self-drilling screw (10) has a first cutting edge (21) provided exclusively in a radially inner region of the drilling tip (12), extending at a first acute angle (?1) to the longitudinal axis (L), and a second cutting edge (22) provided in radially outer region of the drilling tip (12) and extending at a second acute angle (?2) to the longitudinal axis (L), with a first enveloping conical circumferential surface (A1) which is defined by the first cutting edge (21) corresponding, with a maximum deviation of +/?10%, to a second enveloping conical circumferential surface (A2) defined by the second cutting edge (22), and with the first acute angle (?1) corresponding, with a maximum deviation of +/?5°, to the second acute angle (?2).

Abstract: A self-drilling screw (10) has a thread-carrying shaft (11), a head (15) provided at one of its ends, and a drilling tip (12) provided at another of its ends, opposite the one end thereof, with the drilling tip (12) having first and second cutting edges (21, 22) and first and second chip channels (24, 25) associated with the first and second cutting edges (21, 22), respectively, beginning at first and second start points (26, 27) at the free end (14) of the drilling tip (12), and located on opposite first and second sides of the drilling tip (12), with the first and second start points (26, 27) being spaced from the center (Z) of the drilling tip (12) by a mean distance (X) corresponding to from 0.01 to 0.15 of the drilling tip diameter (D), and being spaced from each other by a maximum distance (Y) corresponding to from 0 to 0.8 of the mean distance (X).

Abstract: A self-tapping screw is disclosed. The screw having a shaft bearing at least partially a thread, which shaft defines a longitudinal axis and on whose first end a drill point with a maximum width and on whose opposing second end a head are arranged, as well as having at least one first cutting edge and having at least one second cutting edge. A recess through which the longitudinal axis passes is arranged between the two cutting edges, with the minimum axial depth of the recess corresponding to at least 0.08 times the maximum width of the drill point.

Abstract: Process and device for detecting a lubricant stream in a minimal amount cooling lubricant system (MMKS). Known processes conduct the measurement in the MMKS-supply channel relatively far from the actual working location. They require an incorporation of sensors in the rotating tool container, which is very complex and associated with high costs. These disadvantages are overcome in that the measurement at the lubricant outlet occurs in a separate measurement container, wherein the aerosol component is measured optically and the lubricant film component is measured gravimetrically.
