ABSTRACT:
A resistance tube type smoke generator utilizes a plurality of tube secti, 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.
