Abstract: A method of processing a mineral solid mixture, in particular road construction material, containing impurities with aromatic and/or aliphatic hydrocarbons, wherein the solid mixture is heated to a temperature below 570° C., wherein the solid mixture is heated in at least one heated rotating drum-like apparatus and is passed through at least one container and that the solid mixture is heated during or after the heating process, drum-like apparatus and is passed through at least one container, and in that the solid mixture is subjected to a negative pressure during heating or after heating, and in that the hydrocarbons are extracted from the heated solid mixture by the negative pressure and are rendered harmless by thermal combustion.

Abstract: The invention relates to a plug part (21) for detachable connecting a torch neck (19) of a water-cooled welding torch (7) to a socket part (34) arranged on a hose package (20), having a cylindrical pipe element (22) with an axially running channel (23) for a welding wire (9) and a protective gas (5) and having at least two cooling channels (29, 30) for supplying and returning a cooling fluid, and a union nut (24) rotatably arranged on the pipe element (22), the union nut having an internal thread for connection to a mating external thread on the socket part (34), the invention further relating to such a socket part (34). In order to produce an optimal connection between the torch neck (19) and the hose package (20), a flange (25) having at least one receiving opening for receiving a pin-like element (36) of the socket part (34) is arranged on the pipe element (22) of the plug part (21) in order to fix at least one angular position of the torch neck (19).
