Pagination or Media Count:
A resistance tube smoke generator utilizes a plurality of tube sections, each having a distinct cross-sectional area and electrical resistivity to provide both storage and vaporization via prolonged differential heating of a smoke producing agent. Thermal control may be exercised by sensing change in resistivity of the entire tube or by thermostatic sensors attached to the tubing sections. Patents.
