A method for making a composition containing calcium incorporated into a fatty acid or fatty ester compound and the compositions produced by this method. The transformation system provides a pipeline of transforms for sequentially transforming versions of a design tree and transforming identity-descriptions relating to the versions of the design tree. The tool holder and the tubular compressor are relatively slidable with respect to each other between tool holding and releasing positions. The fastening means include at least one clamp movable between an idle position permitting engagement of the top attachment end by the circular top plate or removal of the circular top plate from the top attachment end of the supporting shaft, and a work position to grip the circular top plate between the radial projection and the clamp. The method includes assigning an identifier to each event.
