Abrasive articles (e.g., abrasive wheels) comprised of abrasive particles and polymeric material such as a polymeric reaction product of components comprising saturated polyol, saturated polyisocyanate, and a free radical source, and methods of making and using the abrasive articles.

The invention relates to an absorbent article that includes a synergistic combination of a) a pH-regulating substance in the form of a partially neutralized superabsorbent material, and b) lactic acid bacteria wherein after being wetted and worn close to the skin, the article has a pH value in the range of 3.5-5.5, preferably within the range of 3.5-4.9, and most preferably within the range of 4.1-4.7.

A composite structure is formed by depositing a one or more coatings on an open-cell foam skeleton to form a higher-density composite foam. In accordance with one aspect of the invention, the composite foam can be a carbon/carbon composite formed by a rapid densification process. The composite structure is suitable for use, for example, as a friction material employed in clutch and brake devices.

A sorptive article is provided. The sorptive article includes a polyolefin, a wax which is miscible with the polyolefin at the melt temperature of the polyolefin but phase separates on cooling of the article, and sorptive particles distributed in the article. Also provided is a method for removing moisture or other vaporous or liquid material from air or an object in the environment utilizing a novel sorptive article of the invention.

There is provided a basket type carrier device for a plurality of articles which comprises a lengthwise extending central wall 51, articles receiving compartments disposed on both sides of the central wall 51, and a handle portion 70. Each receiving compartment is defined by a base wall 63, a side wall 61, 62 which is substantially parallel to the central wall 51, and a pair of end walls 58, 65 and 59, 66 which extend between and are hingedly connected to the side 61, 62 and the central wall 51....

A photochromic article that includes a host material and a photochromic amount of a benzopyran compound, the benzopyran compound represented by one of the formulas: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, and R.sub.10 are selected from hydrogen, a stable organic radical, a heterocyclic group, halogen, a nitrogen-substituted group, and a nitrogen-substituted ring compound.

A foamed polyester resin article is made by a method which includes forming a molten resin mixture containing poly (ethylene terephthalate) having an intrinsic viscosity greater than 0.7 and a moisture content of not greater than 0.03%, a melt viscosity modifier which comprises a multi-stage emulsion graft copolymer of methyl methacrylate and a lower alkyl acrylate monomer, and a heat activatable decomposition-type foaming agent. The mixture is heated in the barrel of an extruder and extruded th...

An apparatus for transporting articles includes a hollow column (10), a shaft (33) furnished with a helical vane (34), and a motor (32). The helical column (10) has a helical track (11) formed therewithin which helically extends along the inner surface of the hollow column (10) in a first direction, and has a first communicating port (12) and a second communicating port (13). The shaft (33) with the helical vane (34) is coaxially and rotatably mounted within the hollow column (10). The helical v...

An absorbent article having, as a back sheet, a porous sheet obtainable by preparing, by melt blending, a melt blended solution comprising 30 to 90 parts by weight of a crystalline polyolefin and 10 to 70 parts by weight of a compound with which the crystalline polyolefin is miscible and in which the crystalline polyolefin will dissolve at or above the melting point of the crystalline polyolefin but which will phase separate below the melting point of the crystalline polyolefin, molding the blen...

An absorbent article for one-time use only, such as a disposable diaper, incontinence guard, sanitary napkin, panty protector or the like, includes at least one hose-like fold (20, 20', 21, 21') which extends in the transverse and/or longitudinal direction of the article. Mounted in the fold (20, 20', 21, 21') are mutually spaced elastic elements (32, 32', 33, 33') which are fastened to respective end parts (27, 27', 28, 28') of the fold on respective sides of fold lines (24, 25) which depart fr...
