Abstract: A filter-tipped cigarette comprises tobacco core 1 contained in casing 3, and filter 2, the filter having first filtering member 4 connected by its one end to tobacco core 1, and a second filtering member provided within first filtering member 4. The second filtering member comprises a distributed system of water-resistant casings having a liquid nucleus, the casings being in the form of tubular capsules 6 and/or ampoule-type capsules 7, which capsules 6, 7 are caused to rupture upon mechanical force is exerted externally thereon. The second filtering member has a volume within the range from 3 to 75 percent by volume of the volume of the first filtering member. The filter-tipped cigarette provides high-quality tobacco smoke cleaning along with enabling the smoker to vary the efficiency of tobacco smoke cleaning and simultaneously flavor tobacco smoke.

Abstract: Electrodynamic separation of nonmagnetic free-flowing materials is accomplished by feeding the flow of a material into a region of maximum intensity of a variable nonuniform magnetic field for inducing maximum eddy currents in electrically conducting particles of the material being separated and producing maximum electromagnetic forces which deflect the electrically conducting particles from the direction of feed of the material being separated.The variable nonuniform magnetic field is generated by an electromagnet having a closed magnetic core with a magnetic air gap defined by pole pieces. The electromagnet pole pieces are symmetrically divergent from the pole axes in a plane substantially perpendicular to the direction of feed of the material being separated.
