Abstract: The invention relates to a cutting insert holder, having a central axis and at least one first receptacle for fastening a first cutting insert to the cutting insert holder, and having at least one second receptacle for fastening at least one second cutting insert to the cutting insert holder, wherein the first receptacle and the second receptacle are arranged offset from each other in the circumferential direction about the central axis, wherein the first receptacle and the second receptacle are configured and arranged in such a way that a first rake face associated with an active main cutting edge of a first cutting insert arranged in the first receptacle has a first orientation along the circumferential direction, wherein a second rake face associated with an active main cutting edge of a second cutting insert arranged in the second receptacle has a second orientation along the circumferential direction).

Abstract: The invention relates to a blade means (1) for a mixer, e.g. an immersion blender (2) or stand mixer, which at least comprises: a rotational shaft (3); at least one blade (4) which extends from the rotational shaft (3) and has at least one cutting edge (5); and a plurality of serrations (6) which are formed in the at least one cutting edge (5), wherein the individual serrations (6) are spaced apart from one another by a planar portion (7) of the at least one cutting edge (5), wherein the planar portion (7) of the at least one cutting edge (5) is less sharp than the serrations (6).

Abstract: The present invention relates to a composition based on monofluorometal complexes, a process for the production of monofluorometal complexes, in particular a catalyst system comprising metallocene monofluorides and aluminum alkyls, as well as the use of the catalyst system for the polymerization of unsaturated compounds, in particular for the polymerization and copolymerization of olefins and/or dienes.

Abstract: A method for joining together a plurality of tubes to form a frame, such as a bicycle frame, includes providing a plurality of projections upon an end portion of a tube for effecting a projection weld with each projection. The tube end portion complements or corresponds to the contour of the surface of a tube to which it is joined so that when the tubes are contacted with one another only the projections make contact thereby leaving a gap of uniform width between the pipes. After tacking the pipes together with projection welds, the gap around each joint is filled with brazing solder.
