  • Patent number: 11721946
    Abstract: An optical system element includes a first enclosure designed for receiving in circulation a functional fluid and at least one inlet and/or outlet window located on the first enclosure and through which a light beam can pass. The inlet and/or outlet window includes two viewports which delimit a spacer cavity adjacent to the first enclosure. The spacer cavity is designed to receive a second fluid with a predetermined optical index and is equipped with a device for adjusting the pressure therein. Degradation of a beam during its passage through the inlet and/or outlet window can be limited by careful selection of the optical index of the second fluid and the pressure in the spacer cavity.
    Type: Grant

  • Publication number: 20190343977
    Abstract: Described herein is a method of using volatile compositions to limit, decrease or eliminate a perception of fecal malodour. Such compositions include a malodour antagonist system associated with perfuming ingredients performing as malodour counteractant, in a combination that significantly reduces the perception of fecal malodour. Such compositions, methods of using the compositions in combination with delivery systems and their applications in consumer products are described herein.

  • Publication number: 20120138767
    Abstract: An optical component (12) such as a mirror is supported by a device (17) comprising two levers (3, 4) for example articulated by flexible strips (9) such that their centre lines (13, 14) intersect at a point (15) defining a pivot and located beyond the end (2) of the device (17), at mid-depth of the component (12), the weight of which is vertically in line with this point (15), does not cause deformation of the component.
