Abstract
1,173,449. Tobacco-smoke filters. LEMO Ltd. 7 Aug., 1968 [7 Aug., 1967], No. 36071/67. Heading A2C. [Also in Division C1] A tobacco-smoke filter includes at least section consisting essentially of calcium hydroxide in particulate form. Preferably the particles are of a size that will pass a 60 A.S.T.M. mesh sieve but be retained by an 80 A.S.T.M. mesh sieve. The calcium hydro_xide may be retained between conventional filter parts, and the filter may be incorporated in a cigarette holder or incorporated as part of a filter tip of a cigarette. The preparation of the particulate calcium hydroxide is also disclosed (see Division C1).
