Abstract: The invention provides a method of welding together articles made of a thermoplastic plastic material by means of a butt welding process, whereby the two articles to be welded together are held in place in coaxial relationship by means of clamping devices. Then, the two articles are heated up by means of a heating device that can be placed between the two articles to create a molten up welding zone in the region of each of the free ends of the two articles. As soon as the welding zone has reached the proper temperature, the two articles to be welded together are pressed together to create a bulge. Finally, the temperature of that bulge is continuously monitored and the temperature of the material in the interior of the afore mentioned welding zone is calculated according to the formula ##EQU1## until such a temperature is reached at which the articles can be removed from the clamping devices.

Abstract: In a process for treating composite elements of solid organic and/or inorganic composite materials-such as composites of metal/metal, plastic/plastic, metal/plastic or mineral composites with metals and/or plastic materials-solid particles are produced from the composite elements and they are added to a transport fluid, wherein at least one flow obstacle which crosses the flow of the mixture of solid particles and transport fluid is moved relative to said flow as a flow-breakaway edge for forming eddies which acceleratingly break up the mixture. The mixture is fed to the separation or break-up procedure at the flow-breakaway edge or edges with an acceleration of 20 to 25 m/sec.sup.2 and the composite element is preferably crushed prior to the separation or break-up procedure.
