Abstract: A process for the production of a fluorinated quartz glass including the steps of generating SiO2 particles in a synthesis burner; depositing the resulting SiO2 particles into a body; and vitrifying the resulting body, wherein a fluorinating agent having a boiling point greater than or equal to ?10° C. is supplied to the synthesis burner.

Abstract: The disclosed subject matter generally relates to a lighting device including at least two optical output modules for jointly providing transformable output light. The transformable output light is transformable a diffuse light output and a light output that has higher contrast than the diffuse light. Accordingly, the inventors realized that an enhanced user experience for vehicle occupants is provided by a lighting device that can seamlessly transform its output light between diffuse light to more high contrast light. For example, a vehicle interior component may be illuminated with a diffuse light when it is in one state, e.g. when it is not used. In a second state, when the component is used or intended to be used, it may be illuminated with a high contrast light to provide the user with more helpful assist light.

Abstract: A housing for enabling coupling of light from a light source to an optical light guide. The housing allows for the optical light guide to rotate about its axis with respect to the housing and a light source while at the same time maintaining the optical coupling with the light source. Accordingly, it is desirable to couple light from a light source to an optical light guide, where the optical light guide is freely rotatable about its axis. This is obtained by a locking mechanism of the housing where the light source is arrangeable. The locking mechanism includes a circumferential structure adapted to receive at least one radial locking member of the optical light guide. The circumferential structure is configured such that the optical light guide is rotatable about its axis in the locking mechanism while maintaining a spatial relationship between the end portion of the optical light guide and the light source.

Abstract: A deformable carrier assembly adapted to hold an elongate light guide in a vehicle, the deformable carrier assembly including: a first component adapted to receive and retain a first portion of the elongate light guide and including a break-away pin at an end thereof; and a second component adapted to receive and retain a second portion of the elongate light guide and including a loop structure at an end thereof; wherein the loop structure is adapted to engage the break-away pin and couple the first component to the second component; and wherein the break-away pin is adapted to be sheared off of the end of the first component and decouple the first component from the second component when a lateral force is applied to one or more of the first component and the second component.

Abstract: The invention relates to the nozzle construction for thermal spraying by means of a suspension, in which particles are contained, or a precursor solution, by means of which particles or precursor solution a layer is formed on a substrate, and which suspension or precursor solution is fed into a burner chamber or into a plasma torch, in which heating and acceleration of the particles is achieved, wherein a connection point for feeding the suspension or the precursor solution, a holder, and a nozzle insert are present. The nozzle insert has, with a tubular element arranged in the direction of the burner chamber or perpendicularly in HVOF flame or plasma torch and with an end face arranged opposite the burner chamber, a flange-shaped expanded section, which lies against a seat formed in the holder in the installed state.

Abstract: An yttrium oxide coating has a porosity of 1.5% or less and contains monoclinic yttrium oxide at a ratio of 1% or more and 30% or less to the sum of monoclinic yttrium oxide and cubic yttrium oxide in the coating. The coating is formed, for example, by thermal spraying a thermal spraying material containing yttrium oxide particles and a dispersion medium.

Abstract: The disclosure provides a method of producing thermally sprayed Al2O3 coatings having a high content of corundum without any property-reducing additives. The coatings may be utilized particularly in the field of electrical insulation, as a dielectric, and as protection from wear. The thermally sprayed Al2O3 coatings have a porosity of no more than 19%, and a high content of ?-Al2O3 (content of corundum) of at least 72% by volume.
