  • Patent number: 6982346
    Abstract: A process of making D-panthenyl triacetate which includes reacting D-panthenol with acetic anhydride in the presence of the catalyst polymer bound dimethylaminopyridine to form an exothermic mixture. The so-produced acetic acid, and the catalyst are removed from the exothermic mixture which is then neutralized with sodium hydroxide. Sodium acetate in the form of a solid is removed by filtration. The D-panthenyl triacetate is useful in cosmetic compositions.

  • Patent number: 6895724
    Abstract: Laminated hip and ridge asphalt shingle having a first, a second and a third layer laminated together by a lamination adhesive. The first layer is of two L-shaped configurations, each having a horizontal head portion and a vertical butt portion. The horizontal head portions are superimposed on each other, while the vertical butt portions are placed adjacent to each other and form a gap which allows bending of the first layer thereby preventing stress and breaking. The second layer overlaps the firs layer. The third layer only overlaps the head portion of the second layer. The top surface of the shingle is coated with mineral granules, while portions of the undersurface of the shingle are coated with a self-seal adhesive to secure the shingle to the hip or ridge of a roof.
