A microfibrous sorbent article is provided. The microfibrous sorbent article comprises an elongate boom having a substantially oval cross-section. The boom is formed of multiple adjacent microfibers layers, the layers being bonded to each other by entanglement of fibers between adjacent layers. The boom further contains ion exchange resin, selectively absorbent particulate material, catalytic agent or selectively reactive particulate material.

Articles comprised of 2-acrylamido-2-methyl propane sulfonic acid (AMPS) polymer on a blood-contacting substrate or the like are useful in medical devices in which antithrombogenic characteristics and slippery surfaces are required.

This invention provides a smoking article having reduced sidestream smoke in the inter-puff period. A smoking article according to the invention may have segments of a high level of tobacco-containing material interconnected by segments of low level of tobacco-containing material which are capable of maintaining smoulder in the inter-puff period and re-igniting the segments of a high level of tobacco-containing material in the puff period. Alternatively, a smoking article according to another as...

A structural article for high temperature applications comprises a body formed of at least partially consolidated, particulate silicon nitride, a conformal outer coating of silicon nitride or silicon carbide on the body, and a conformal intermediate layer of a silicon, oxygen and nitrogen-containing compound, i.e. silicon oxynitride, chemically bonded to both the body and the outer coating. The method for making such an article comprises providing a body formed of at least partially consolidated...

Low sidestream cigarettes having cigarette rods comprising paper wrappers including compounds of a type which effect a sidestream reduction of at least 30% when used on rods not exceeding 20 mm in circumference.

Stitchbonded articles and methods of making same are presented. The articles may be either dual purpose wiping/scrubbing articles or only scrubbing articles. The articles may be constructed to have three dimensional scrubbing surfaces. Both the dual purpose articles and the scrubbing articles comprise thermoplastic nodules melt-bonded to the stitching yarn, and preferably to the fibers of an absorbent material, the nodules providing the primary scrubbing utility.

A molded article is disclosed. The molded article includes a shell having a reservoir, a deck surrounding the reservoir and an apron. The shell has an exterior non-finish side and an interior finish side. The non-finish side of the shell is coated with a polymeric material. The polymeric material forms a layer on the non-finish side of the shell. The polymeric layer which is formed on the non-finish of the apron of the shell includes a rectangular area of reduced thickness and covers most of the...

A smoking article which comprises tobacco treated with a high loading level of humectant and which has been expanded by a high level expansion process to produce expanded tobacco having a humectant loading level in the range of 4% to 15%. The particulate matter, water, nicotine and humectant free (PMWNHF) to nicotine delivery ratio of smoking articles according to the invention and smoked under standard machine smoking conditions is not more than 8 to 1.

A security article such as a banknote, credit card, identity card or travel document includes a security element which is visually detectable in transmitted light to display portions which transmit light and portions which are opaque, the security element including a plurality of layers that include a light-transmitting support layer and two or more series of opaque regions. The arrangement of the opaque regions is such that at certain parts of the security element the regions overlap to prevent...

An abrasive article comprising a plurality of abrasive particles bonded together, bonded into a substrate, or bonded onto a backing by a cured binder, the cured binder being formed by solidifying a binder precursor comprising an aqueous acrylate polymer emulsion. In preferred embodiments, the binder precursor includes a phenolic resin.
