(57) A manipulator device to apply modules around a pipeline during assembly has two jaws (22) mobile between an open and a closed position and configured to house the respective portions (9) of the module (8), and an articulated mechanism (23) having a plurality of degrees of freedom to place the jaws (22) in a loading position and in a position wherein the jaws are aligned with the pipeline (2) during assembly.

(57) The invention relates to a method for the thermal treatment of clays, said method comprising the following steps: preheating the clay, which is suspended in a carrier gas, in a heat exchanger (150); thermally treating the clay in a calcination stage (160) operated under chemically oxidising conditions; subsequently thermally treating the clay in a calcination stage (17) operated under chemically reducing conditions; cooling the clay in a cooling stage (180) operated under chemically reducing conditions; cooling the clay in a cooling stage (190) operating under chemically oxidising conditions. The alternating sequence of the redox potential of the surroundings leads to a black to grey product instead of a red-brown product, with simultaneously less emission of noxious gas. The method conducted in such a way can be operated in a stable manner.
