Abstract
1488156 Resistively heated tube RHONEPOULENC SA 14 Nov 1974 [15 Nov 1973 7 Oct 1974] 49326/74 Heading H5H A transparent flexible heating tube has at least one helical heating conductor and at least one helical temperature measuring probe embedded in its wall, As shown, eight helical heating conductors 2 are wound on a pipe 1 surrounded by a sheath 3. One of the conductors 2 may additionally act as the temperature probe and one may act as an earthing element. The conductor can be a metal wire or carbon filament. In Fig. 4, a nickel tape resistor 4 is helically wound on pipe 1, and a filamentary temperature probe 5 is helically embedded in pipe 1. The tube is preferably made by forming the pipe 1 or a temporary tubular mandrel, helically winding under appropriate tensions the resistor and probe about the pipe 1, covering the pipe with a sleeve 3, vulcanizing the pipe and removing the mandrel. The mandrel may be loosened by stretching or it may be heat shrunk during vulcanization. Two serially connected helically wound pipes may be enclosed in a single sheath. The pipe 1 is made of p.v.c., polyurethane or silicone elastomers. The sleeve 3 may be formed by shrinking on a sheath of P.T.F.E. or by immersing in polymer solution. A lacquer of silicone elastomer may be applied to the inside and outside of the tubular heater. Blood, water or gas may be heated in the tubular heater. The probe is connected to a measuring bridge.
