  • Patent number: 6509404
    Abstract: An ionomeric particulate composition made by suspension polymerization is provided. The composition comprises at least one vinyl monomer; an acid monomer; a metal oxide; at least two surfactants, one of which is a monomer surfactant; and polyacrylamide. The particulates' size can be controlled by use of the polyacrylainide and various surfactants, and not through the conventional means of homogenization. Particle size in the range of less than 10 micrometers can be made. The ionomeric particulate is made in the absence of a chain transfer agent and thus can have high molecular weight.

  • Patent number: 6491775
    Abstract: A method of adhesively bonding an adhesive coated, semi-rigid film to a substrate is reported. The method utilizes at least two alignment tools that are each positioned to substantially contact the surface of a substrate at an outer edge of the substrate. The adhesive-coated, semi-rigid film is then interposed between the first and the second alignment tools and the adhesive is brought into contact with the major surface of the substrate. The semi-rigid film is then aligned by contacting a first side edge of the semi-rigid film with a major surface of a first alignment tool and contacting a second side edge of the semi-rigid film with a major surface of a second alignment tool such that the film is aligned relative to the edge of the substrate. After alignment, pressure is applied to at least a portion of the surface area of the first side of the semi-rigid film to effectuate adhesive bonding of the film to the major surface of the substrate.

  • Patent number: 6358133
    Abstract: A cylindrical, abrasive grinding wheel having a cylindrical abrasive region with an abrasive surface at an outer circular band thereof. The abrasive region includes layers of abrasive particles. The layers of abrasive particles can be tilted with respect to an axis of rotation of the grinding wheel or they can such that grooving in the grinding wheel and a workpiece ground by the grinding wheel can be reduced. Alternatively, the abrasive region can be formed from a plurality of abrasive segments each having layers of abrasive particles. The layers of abrasive particles can be staggered in the direction of the axis of rotation from one segment to another. This can also reduce grooving in the grinding wheel and workpieces.

  • Patent number: 6358601
    Abstract: The present invention relates to an approach for improving the compatibility of antistatic agents and ceramer hardcoats so that such hardcoats can be provided with excellent antistatic characteristics. In particular, it has been discovered that the antistatic agents of this invention can be combined with aqueous sols of surface treated, colloidal inorganic oxide particles having a negative surface charge without destabilizing the negatively charged colloids. It has further been discovered that the combination of the antistatic agent and negatively charged, surface treated colloids of this invention interspersed in a cured ceramer matrix unexpectedly provides dramatic improvements in antistatic protection. The antistatic approach of this invention also provides excellent antistatic protection over a wide range of relative humidity, including conditions in which RH is below 40%, especially at 15% to 40% RH.
