Abstract: An apparatus is provided that is configured for attachment to an aerosol can to permit mixing of contents therein. The apparatus includes a generally flat base portion coupled to a drive shaft orthogonally oriented relative to the base portion, and a securing strap attached to the base portion. The securing strap is configured to engage or grip a cylindrical end portion of an aerosol can to secure the aerosol can to the apparatus, whereby the drive shaft is configured to be mounted within a drill chuck to permit the mixing apparatus to rotate an aerosol can attached thereto for mixing contents within the aerosol can.

Abstract: The invention relates to a tool holder with a tool holding fixture, in particular a clamping chuck such as a contracting chuck, a draw-in collect chuck, a hydraulic expanding chuck and a high-precision chuck, and a shank of a tool, in particular a rotary tool, accommodated in it, wherein the tool holder contains a means for preventing the tool from being pulled out, locking it against axial displacement. This pull-out preventing unit comprises at least one locking element and at least one locking groove, which corresponds to the said locking element, receives it and interacts with it in a positively locking manner. In this case, both the locking element and the locking groove are formed at least partly in the manner of a ball head. Preferably, the tool has the locking grooves.

Abstract: A lever is mounted about an oscillation axis for limited oscillation relative to a first component. A linear tension spring latching member is mounted for rotation on that lever about an axis eccentric to the oscillation axis, the latching member being mounted for frictionally retarded rotation. In the joined condition of second and first components, a latching pin projects from the second component in parallel spaced relation to the oscillation axis and the latching member axis. The tension spring latching member includes a latching hook at its distal end for engagement with the latching pin so that in the latched condition in the components, the spring latching member is tensioned between the latching pin and the eccentric axis.
