Abstract (en)
[origin: GB2221023A] Central tubular element (126) is connected, on one side, by means of a first ball-and-socket joint (138) and a first compensator (144) to a first connector (128) supplying pre-heated air and on the opposite side, by means of a second ball-and-socket joint (140) and a second compensator (146) to a second connector (130). In order to reduce the length of the device, the second joint (140) is oriented in the opposite direction to the said first joint (138), its centre of curvature (Y) being located on the axis of the said second connector (130) on the inside of the latter. <IMAGE>
