Abstract
A filter for tobacco smoke is formed, at least to a major extent, of alginic acid, or a derivative thereof, in spongy form. It may be reinforced by fibre-like materials, and the following may be added (a) to increase its absorbing capacity, viz:-silica gel, alumina, absorbing earth, ion exchangers, and (b) to oxidize the nicotine, viz:- the oxides of cerium, vanadium, copper, iron or manganese. Certain of these substances may be formed on the filter, after manufacture, by treatment with solutions. The material is pressed into sheet or continuous-rod form from which cigarette tips are cut and pressed by rollers. They may be covered with paper or cellulose wool. The Specification as open to inspection under Sect. 91 comprises also filters made of natural sponge, regenerated cellulose, cellulose ester, cellulose ether, polyvinyl alcohol, polyvinylic, polyacrilic or polymethacrylic resin, polyamides or sulphonated phenolformol. This subject-matter does not appear in the Specification as accepted.
