  • Aerosol container
    Patent number: 9327899
    Abstract: An aerosol container (1) comprising a body (50) and cone (60) and encasing a composite spout (30) and bag (40) combination. The composite spout (30) has a metal tubular section (10), adapted to accommodate a valve arrangement (70, 75) and a polymer fishtail section (20), adapted to form a leak-proof seal with the bag (40). A product is filled into the bag (40) and propellant is filled into the sealed chamber defined between the outside of the bag (40) and the internal surface of the body (50)/cone (60).

  • Coated cutting insert and method for making the same
    Patent number: 8668982
    Abstract: A coated cutting insert for removing material from a workpiece that includes a substrate is disclosed. A wear-resistant coating on the substrate that includes an alumina layer and a Zr- or Hf-carbonitride outer layer deposited on the alumina layer. The Zr- or Hf-carbonitride outer layer is subjected to a post-coat wet blasting treatment. The wet blasting changes the stress condition of the exposed alumina coating layer from an initial tensile stress condition to a compressive stress condition.
