Abstract: A smoking device comprising a longitudinal shell with a first cavity. A channel in said first cavity has a longitudinal shape and a peripheral wall, a top, a bottom defining a second cavity. The top and bottom of the channel are substantially open. Said first cavity comprises a compound member with an electrically conductive winding. The open top of the channel meets the outer surface of the shell, and the shell has an opening in its outer surface corresponding to the open top of the channel, thereby allowing ambient air to flow into said second cavity. When electrical current flows through the winding, the compound member generates heat and heats air flowing through said second cavity. Air flows through longitudinal holes inside the compound member, through grooves in the exterior of the compound member, air and passes through and heats the smoking material.
Abstract: A filter for a smoking article or an aerosol generating product comprising filter material and three capsules comprising additive, the capsules being disposed in sequence in a direction along a longitudinal axis of the filter.

Abstract: A method of forming a fibrous web including the steps of providing a fiber slurry, depositing the fiber slurry between an inner forming wire and an outer forming wire, wherein the outer forming wire comprises a structured fabric and the inner forming wire contacts a segment of a forming roll, and rotating the forming roll so that the fiber slurry moves into contact with the structured fabric.
Abstract: A refining member for a pulp refiner comprising a refining body with a refining surface comprising refiner bars separated by refiner grooves and teeth. Each of the refiner bars extend from a radially inward position on the refining surface to a first radially outward position on the refining surface, and the teeth extend to a second radially outward position on the refining surface. The second radially outward position is nearer to an outermost part of the refining body than the first radially outward position. The refiner bars are adapted to refine wood fibers, and the teeth are adapted to break up fiber bundles.
Abstract: A container assembly and method is provided for concealing and storing a water bong. The container assembly, for example, is generally a cylindrical container comprising a upper container, a upper container lid, a lower container, a percolator, a inlet port, a neck, and a bowl, wherein the neck and the bowl are configured to be stored in the lower container. The container assembly and method also involves sliding the percolator to and from an extracted position that permits a smoker to inhale combustible substances, to a concealed position within the upper container.

Abstract: Described is a pouched product for oral use with a filling material and a saliva-permeable pouch. The pouch is made of a saliva-permeable packaging material that includes fibres and enclosing the filling material. The pouch has a first seal joining at least two plies of the packaging material. The at least two plies are interconnected in the first seal by inter-ply fibres, the inter-ply fibres being fibres which are present in at least two plies of the at least two plies.
Abstract: A method for preparing a tar extract with aroma characteristics from a discarded cigarette butt includes: (1) adding the discarded cigarette butt to an extraction solvent, and carrying out subcritical fluid extraction to obtain an extraction solution; (2) carrying out vacuum filtration on the extraction solution, and carrying out vacuum distillation on the filtrate to obtain a concentrated extractum; and (3) carrying out molecular distillation on the concentrated extractum, and collecting a light fraction of the molecular distillation to obtain the tar extract with aroma characteristics. Through the subcritical fluid extraction and separation by the molecular distillation to prepare the tar extract, harmful substances in the tar are removed, and the aroma components are retained. The tar extract is applied to a cigarette to improve the aroma, smoke and taste characteristics of the cigarette.
