A method for decomposing a gaseous aliphatic hydrocarbon halide compound more simply is provided. A hollow profiled bar is directed through a stationary supply of a liquid coating agent on a bent, arc-shaped track, whereby inner walls of the hollow profiled bar are moistened with coating agent, and the hollow profiled bar is guided along a rising track directly after running through the coating agent supply. A primary coupler connects to the port. The front wheel assembly is designed so that when the castors swivel from their orientation for forward travel, the fixed wheel assembly is caused to be lifted off the ground. It also relates to their utilisation in therapy and to the corresponding pharmaceutical compositions. The feed materials are selected so that, in an overall sense, the reactions of the feed materials in the molten bath are endothermic.
