The glazing may also be utilized as part of a laminated glazing or insulated glazing unit. A method of manufacturing the glazing is also provided.

  • Patent number: 10477936
    Abstract: A small and portable workstation for manicure and pedicure procedures may have a soft, impervious outer layer, undamaged by, yet easily cleaned with, solvents such as rubbing alcohol (e.g., 99% isopropyl) and nail polish remover (i.e., acetone). Viscoelastic “gel” skin of synthetic hydrocarbon polymer overlies a body of plastic, metal, wood, or expanded polymer (foam). An elastomeric foam such as polyurethane may contribute to flexibility and comfort, resting hand or foot on a gentle, almost horizontal, incline on the front portion of the working surface, transitioning to a wave shape of almost semicircular cross-section along the rear portion thereof. Wells hold tools and materials between organizing dividers. A removable base is a tray for supplies.
