ABSTRACT:
A tobacco smoke filter for use with a cigarette comprising a tube having a conical disc at its upstream end adjacent the tobacco. A capillary orifice through the apex of the conical disc permits discharge of tobacco smoke from the cigarette at high velocity into a downstream chamber for sublimation of alkaloids and other harmful matter to solid particles by rapid expansion. A parabolic disc is positioned in line with the high velocity jet to trap the solid particles and reverse flow to promote turbulence. The disc has a periphery closely adjacent the inner wall of the tube to promote a high speed flow around its edge. The resulting turbulence causes additional deposition of solids on the disc's downstream face. A tube integral with the disc extends to a circular opening in the downstream end of the tube for discharge of filtered smoke. Certain surfaces in the filter, such as the upstream side of the disc, may be coated with a catalyst to enhance a beneficial chemical reaction of constituents in the tobacco smoke.
