Abstract
1329956 Tobacco-smoke filters F J BURRUS & CIE 29 July 1971 [14 Aug 1970] 35761/71 Heading A2C A filter comprises at least three different filtering agents, at least one of which agents is primarily intended to remove smoke components with a particle diameter of more than 0.1 micron, and at least one other of which agents is a polar adsorption agent intended to remove chemically polar smoke components with a particle diameter of less than 0.1 micron. The specified polar adsorption agent is porous magnesium silicate of 0.1-2.0 mm particle size, and the agent for removing particles of more than 0.1 micron diameter may be a wad of cellulose acetate or crepe paper. As shown in Fig. 1, wads 1, 3 are formed of cellulose acetate fibre or crepe paper as is also a carrier material 6 on which mixed magnesium silicate particles 4 and activated carbon particles 5 are distributed. In Fig. 2, the particles 4, 5 on separate carriers are separated by a part 8. In Fig. 3, the particles 4, 5 are separated in the manner shown, and may be loose or bonded together at their contact points.
