A heat spreader for an emissive display device, such as a plasma display panel or a light emitting diode, comprising at least one sheet of compressed particles of exfoliated graphite having a surface area greater than the surface area of that part of a discharge cell facing the back surface of the device. The aim of the invention is to prevent the fluid conduit piece and other fluidic devices from being damaged in the event of a spontaneous exothermic reaction in the working fluid. The belt is guided over deflection drums in the loading station and in the unloading station. A method for forming a special giant all-steel radial OTR tire in a continuous process is also provided. The length of the time period is informed to the mobile station by the network on a dedicated or on a broadcast channel.
