Patent number: 9789226Abstract: Compositions and methods for the surface appearance of the skin a subject are provided. An injectable composition comprising at least hyaluronic acid or a salt thereof; and an effective amount of at least mepivacaine or a salt thereof are provided. The hyaluronic acid optionally has an average molecular weight ranging from 50,000 to 10,000,000 Daltons, and may be crosslinked hyaluronic acids, non-crosslinked hyaluronic acids, or a combination, in some embodiments. The compositions and methods of the present invention are useful for treating and preventing the cutaneous signs of chronological aging and/or induced by external factors such as stress, air pollution, tobacco or prolonged exposure to ultraviolet (UV) exposure, impaired surface appearance of the skin, impaired viscoelastic or biomechanical properties of the skin, and/or the long-lasting filling of volume defects of the skin.Type: GrantFiled: February 16, 2016Date of Patent: October 17, 2017Assignee: TeoxaneInventors: Francois Bourdon, Stephane Meunier

Patent number: 9683595Abstract: A metallic locking washer is configured to be mounted in a screw/nut system to engage between a nut and a bearing element. The metallic locking washer has a contact face suitable for coming into contact with one or the other of the nut and the bearing element. The contact face has a surface that is suitable for being brought along in friction against one or the other of the nut and the bearing element when the nut loosens. The contact face is coated, by thermal projection of an additive material, with a rough coating forming a rough surface, which increases the friction forces between the contact face of the metallic washer and one or the other of the nut and the bearing element.Type: GrantFiled: September 12, 2013Date of Patent: June 20, 2017Assignee: NORD-LOCK INTERNATIONAL ABInventors: Pierre Chalandon, Stéphane Meunier, Christophe Delcher
