  • Patent number: 7263777
    Abstract: An apparatus for scribing the coating on a coated panel; comprising a base, at least one linear guide affixed to the base, a moveable table, a pivotable bracket mounted on the base, a cutter element mounted on the bracket; a loading mechanism positioned on top of the bracket, such that when the cutter element in the cutter assembly is brought into contact with a panel positioned on the moveable table, the loading mechanism applies a uniform force to the panel position on the table. The cutter element in contact with the panel scribes the panel through the coating thereby forming a scribe of at least one line on the panel.

  • Patent number: 7248350
    Abstract: The invention is directed to a method for determining repairability of an original clear coat applied over a darkly pigmented substrate with a corresponding repair clear coat used in repairing damaged original vehicle coatings. The method non-destructively determines the refractive indices of the original clear coat and the corresponding repair clear coats by acquiring the reflection spectrum of these coats with a spectrophotometer with d/8° measurement geometry with and without the specular components followed by determining the refractive indices with the assistance of the differential spectrum between the reflection spectrums with and without the specular components, and then comparing the refractive indices to determine difference between these refractive indices, wherein when the difference between the refractive indices of the original arid repair clear coats is within an acceptable range, the repair clear coat is used for repairing the original clear coat.

  • Patent number: 7158672
    Abstract: The present invention provides a color recipe calculation method for matt finished, solid color shades, by means of which it is possible to determine the proportion of matting agents in a color recipe in a manner decoupled from the actual calculation of the recipe and is based on a conventional spectrophotometric characterization of a matt sample using a standardised 45°/0° measurement geometry along with an established gloss measurement, or alternatively using a spectrophotometer equipped with a d/8° measurement geometry and analyzing readings taken with the specular component included and excluded.
