This invention pertains to the production of color coatings gradients to be used for color composition customization and for visually displaying alphanumeric data/information on 2D and 3D surfaces. This invention integrates gradient specific programmable computer digital processes to function as internal editors, manipulate information and present the operator with multiple options and production overrides. This invention will make data analysis more interactive by utilizing existing external software applications as editors and expanding the process of visual communications for multiple purposes. While the production of color coatings gradients can be performed manually, it can also be combined with a programmable computer.

This invention pertains to a color coatings blender apparatus to be used for color composition customization for the application of color coatings on 2D and 3D surfaces. The apparatus is comprised of a main body and interchangeable inserts all with central blender chambers and primary and secondary ports, and interchangeable spindles; the configurations of which are governed by coating technical characteristics. This invention integrates gradient specific programmable computer digital processes to function as internal editors, manipulate information and present the operator with multiple options and production overrides. This invention will make data analysis more interactive by utilizing existing external software applications as editors and expanding the process of visual communications for multiple purposes. While the blender apparatus, complete with external selectable appurtenances, can be used manually, it can also be combined with a programmable computer for producing physical gradient layers.

Ketoximes, processes for their preparation, compositions containing them, and a copper extraction process using the compositions. One process for the preparation of the ketoximes comprises the following steps: A) reacting a phenol with a monocarboxylic acid, monocarboxylic acid halide, or monocarboxylic acid anhydride in an inert organic solvent in the presence of an acid catalyst to esterify the phenol; B) removing any water of reaction produced in step A) either during step A) or in a separate step following step A); C) adding a Lewis acid to the resulting anhydrous reaction mixture; D) heating the reaction mixture from step C) to a reaction temperature sufficient to obtain a ketone by the Fries Rearrangement; E) maintaining the heated reaction mixture for a time period of from 2 to 8 hours at the reaction temperature; F) at a time of from half to three-quarters of said time period, adding to the heated reaction mixture additional aliphatic monocarboxylic acid, acid halide, or acid anhydride, optionally with additional Lewis acid, and continuing to maintain the heated reaction mixture at the reaction temperature for the remainder of said time period; G) isolating the ketone reaction product from the reaction mixture; and H) reacting hydroxylamine or a salt thereof with the ketone obtained in step G) to produce a ketoxime from said ketone.
