Abstract: An optical projection system for use with a display surface includes at least one image source comprising an array of source image pixels, a projector to project a first projection of the array of source image pixels, and at least one mirror including at least one curved reflecting surface having a curved profile. The at least one curved reflecting surface is adapted to convert the first projection to a curved second projection directed onto the display surface to provide an array of displayed image pixels on the display surface corresponding to the array of source image pixels, wherein the array of displayed image pixels have constant pixel pitch among adjacent displayed image pixels.

Abstract: The compounds of this invention are suitable matting agents for powder coatings. The compounds are ester amide-containing condensation products optionally comprising at least one ?-hydroxyalkylamide functional group and, for example, are prepared from monomeric ester-amides, oligomeric polyester-amides or polymeric polyester-amides bearing ?-hydroxyalkylamide groups by reacting the hydroxyalkylamide bearing ester amide with another compound such that at least one reactive functional group other than ?-hydroxyalkylamide is also present on the condensation product, and further such that 50% or more of the terminal ?-hydroxyalkylamide functionality has been reacted or converted to groups containing terminal carboxylic acid groups or other reactive groups including, but not limited to, groups reactive with polymers and crosslinkers suitable for preparing epoxy, epoxy-polyester, polyerster, polyester acrylic, polyester-primid, poylurethane or acrylic powder coatings.

Abstract: An optical projection system includes a first image source that is configured to generate a first array of image pixels and a first lens assembly that is configured to project the first array of image pixels onto a non-planar surface. A second image source is configured to generate a second array of image pixels and a second lens assembly is configured to project the second array of image pixels onto the non-planar surface. The first and second arrays of image pixels overlap along a single edge and the combination of the first and second arrays of image pixels covers a continuous portion of the surface.

Abstract: Effective anti-corrosive pigments are obtained using basic or neutral to basic polyvalent metal organophosphonates. The anti-corrosive organophosphonate pigments may optionally contain a co-acidic substance such as silica. The organophosphonate pigments provide ant-corrosive protection comparable to traditional pigments while enabling the avoidance of heavy metals.
