  • LASER ACTIVATION OF ELASTIC LAMINATES
    Publication number: 20080305298
    Abstract: There is provided a method of activating a substantially inelastic laminate to an elastic state by providing an elastic layer bonded on at least one face to a fibrous facing layer. The laminate is directed under laser beams so as to cut fibers of the at least one fibrous facing layer along perforation lanes in at least one region forming a laminate that is extensible and elastic in a direction generally transverse to the direction of the perforation lanes. This laminate is particularly adapted for use in personal care articles.

  • ABRASIVE ARTICLE WITH SUPERSIZE COATING, AND METHODS
    Publication number: 20080216413
    Abstract: Abrasive articles, and methods of making abrasive articles that include a supersize coating or component, such as one configured to inhibit the collection of dust and/or swarf on the abrasive coating. The supersize component can be applied to the abrasive coating after converting the abrasive article with a laser or other conversion mechanism, whether non-contact or mechanical contact. In some embodiments, no fresh or exposed abrasive or backing surfaces exist; that is, the supersize component covers all surfaces.

  • LASER CUT ABRASIVE ARTICLE, AND METHODS
    Publication number: 20080216414
    Abstract: Abrasive articles, and methods of making abrasive articles by using a laser to convert (e.g., cut) at least a portion of the abrasive coating to form the abrasive article. The method includes laser propagation impinging on the abrasive back side (opposite the abrasive coating) and progressing through to the abrasive side. Such a process inhibits ridging effects around cut regions (e.g., openings) on the front side.

  • Glass-ceramic microspheres that impart yellow color to retroreflected light
    Patent number: 6479417
    Abstract: The present invention relates to transparent microspheres (i.e., beads) that impart yellow color to retroreflected light. The microsphere preferably comprise titania plus alumina, zirconia, and/or silica and iron oxide, manganese oxide, or mixtures thereof. More particularly, the present invention relates to fused microspheres that impart yellow color to retroreflected light having both transparency and mechanical properties suitable, for example, for lens elements in retroreflective articles.
