20080244809 | Latex Gloves and Articles with Geometrically Defined Surface Texture Providing Enhanced Grip Method for In-Line Processing Thereof - Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environments; and a method of making same comprising applying a polymeric coagulant coating to a smooth former surface, wherein the coating becomes tacky during drying, applying discrete coagulant particles of selected size, shape and distribution to the tacky coating to attach and protrude from the former surface with the polymeric coagulant coating, dipping the former into an aqueous latex emulsion, wherein the polymeric coagulant coating and the discrete coagulating particles destabilize the latex, thereby developing a latex layer, vulcanizing and stripping the latex article inside out, and dissolving the discrete coagulant particles in water or suitable solvents to reveal the geometrically designed texture with pre-selected size, shape and distribution of impressions providing improved dry, wet and oily surface grip by removal of a fluid boundary layer. | 10-09-2008 |
20080269661 | Easy-to-peel securely attaching bandage - A bandage remains securely attached to the skin of a wearer during extended exposure to arid, humid or wet conditions. The bandage is readily removed from the attached condition upon application of pressure to its exterior surface. Adhesive portions of the contain pockets or microcapsules filled with an adhesive-inactivating ingredient. The pockets are formed in the backing layer. Microcapsules, if present, are incorporated in the adhesive. The adhesive inactivating ingredient comprises oil from vegetable source, mineral source or fatty acids. The wearer ruptures the pockets or microcapsules by applying pressure to the bandage above the adhesive portions. The adhesive-inactivating ingredient is thereby released at the skin-adhesive interface, permitting an easy, pain-free removal of the bandage. | 10-30-2008 |
20090044571 | Knitted Glove with Controlled Stitch Stretch Capability and enhanced cuff - A knitted glove made by creating each of the at least fifteen sections using a separate knitting course on a flat knitting machine providing varying stitch dimensions with one or two yarns in one or more sections. Custom stretch characteristics can be provided using one or two yarns providing a tight glove that provides flexibility and ease of movement. The varying stitch dimension is achieved by 1) varying the depth of penetration of the knitting needle into fabric being knitted by a computer program, 2) adjusting the tension of yarn between a pinch roll and knitting head by a mechanism controlled by a computer and/or 3) casting off or picking up additional stitches in a course. The glove includes four finger components, a thumb component, two palm components, and a wrist component. A padded cuff section can be added to the wrist component for comfort. | 02-19-2009 |

20090077713 | Chemical Resistant Glove Having Cut Resistant Properties - A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described. | 03-26-2009 |
20090183296 | CUT, OIL & FLAME RESISTANT GLOVE AND A METHOD THEREFOR - A flexible cut resistant hydrocarbon flash fire resistant latex glove article is provided, having a flame resistant cut resistant liner and a flame resistant oil resistant polychloroprene polymeric latex coating. The knitted cut resistant fire resistant liner has is made from a composite yarn having a fiberglass core and optionally including a steel fiber. The core has a cushioning core sheath formed by ring-spinning of microdenier staple cut resistant fibers of, for example, para-aramid, and Staple modacrylic fibers can be included with the staple para-aramid fibers. Two wraps of continuous yarns of polyester, para-aramid, or both at a wrap density such that the wraps do not cover the core sheath in its entirety. In the absence of steel fiber, the cut resistant hydrocarbon flash fire resistant glove exhibits good electrical insulation characteristics even with sweat generated from hand preventing short circuit of electrical circuits. The glove is flexible due to the low denier of the composite yarn and is highly breathable especially when only the palm and fingers are coated with polychloroprene polymer. | 07-23-2009 |
20090314215 | Odor control additive for animal litter - An odor control additive present in a litter formulation provides release of fragrance or odor masking scent only when litter is used by a cat or other animal within a litter box. The odor control additive comprises a plurality of fragrance scent microcapsules that contain fragrance scent oil. This central, fragrance scent oil is encapsulated in a microcapsule cell wall, which prevents evaporation of the fragrance scent oil and prevents overpowering of litter smell in a closed room resembling an unscented litter composition. When cat or animal enters the litter box, a load is applied to the fragrance scent microcapsules, which readily breaks releasing the fragrance contained therein. The fragrance scent microcapsule cell walls also degrade by swelling and degradation when wet by animal urine thereby releasing fragrance. Fragrance evaporating from the ruptured microcapsules provides odor control and a pleasant scent. | 12-24-2009 |
