A smoking article comprising a smoking rod, a filter and ventilation means incorporated in the filter and communicating with the outside of the smoking article, viscous fluid in the ventilation means closing or partially closing the ventilation means, the viscous fluid being displaceable during use of the smoking article enabling ventilation to occur.

A pellet formed from a mix of two polymer materials which are non-homogenous is extruded through a die to form a highly roughened surface creating an enhanced melt fracture appearance. The extrusion is chopped into pellet form to provide a large surface area pellet to be used as a harbour for biomass in water treatment processes. Large quantities of such pellets in a filter provide a very effective filtration effect, largely because the highly roughened surface provides an enormous number of cav...

A medical bandaging material, for example, for use as a wound dressing, soft-tissue support bandage, brace or orthopaedic splinting bandage, comprises two superposed layers of, for example, a woven, knitted or non-woven material spaced apart by strands of mono-filamentary or fibrous layers. The interstitial spaces may be filled with a hardenable resin and/or pharmacologically active agent.

Multilayer high transmittance, low emissivity coatings on transparent substrates feature a special antireflective base film of at least two parts on the substrate-near side of a metallic, reflective film. A first of the two parts is in contact with the metallic film. This first film-part has crystalline properties for causing the metallic film to deposit in a low resistivity configuration. The second of the two film-parts supports the first part and is preferably amorphous. Coated articles of th...

The invention relates to a cigarette paper having a low total filler content, 20% by weight of the paper or less, a proportion of the filler being a filler capable of effecting visible sidestream smoke reduction. The basis weight of the paper is about 30 g m.sup.-2 or more. Smoking articles made with such papers provide a synergistic sidestream smoke component reduction when compared with control cigarettes. Papers according to the invention with the addition of various burn additives are also d...

A dispenser for dispensing individual interleaved and/or releasably attached articles such as sheets impregnated with moisture or a composition or substance useful for treating, cleaning and/or disinfecting various surfaces, including the human skin. The dispenser includes a dispensing element including at least one larger aperture and a smaller aperture entirely separated from one another. A closure or lid can usefully be incorporated. The articles may easily be reached from above the top surfa...

An article comprising a substrate having markings which are provided by at least two fluorescent materials which have different excitation spectra in the ultraviolet region of the spectrum and different emission spectra in the visible region of the spectrum. The invention also provides a method of marking an article for identification.

The invention relates to novel composite materials comprising (a) an inorganic or organic bulk material having covalently bound to its surface initiator moieties for radical polymerization; and (b) a hydrophilic surface coating obtainable by applying one or more different ethylenically unsaturated hydrophilic macromonomers of formula (1) as outlined in the claims to the bulk material surface provided with the initiator radicals and polymerizing said macromonomers. The composite materials of the ...

A close-fitting garment, especially a swimsuit, has panels of elastic stretch fabric joined at seams and shaped to conform with muscle groups of the body, in particular in the abdominal region and at the glutel region.

The present invention provides various microfluid processing architecture-bearing, polymeric articles. The articles may include microelectronic, microoptical or microchemical elements. The article also may include inorganic thin film coatings.
