Abstract:

A process for making a colored article of manufacture is disclosed. Accordingly an article of manufacture is first prepared of a material selected from the group consisting of metal, wood, glass, ceramic, masonry and polymeric materials. A polymeric coating (superstrate) is then applied to at least a portion of the surface of the article. At least a portion of the superstrate is brought into contact with a material system that contains (i) water, (ii) a carrier, (iii) a dye and (iv) a diol, under conditions calculated to bring about diffusion of said dye into said superstrate.

Appl. No.:

12/258698

Inventors:

JAMES M. LORENZO - Mars PA, US
Robert A. Pyles - Bethel Park PA, US
Raymond L. Goodson - Sandy UT, US

International Classification:

F41H 5/24

US Classification:

89 3604

Abstract:

The present invention provides a bi-active method of mounting a monolithic polycarbonate sheet or a laminate in a semi-rigid metallic framing system along two parallel sides of a rectangular shaped sheet or laminate with the two shorter parallel sides being unconstrained. In the case of a square shaped sheet, two parallel sides are supported in the semi-rigid frame, and the other two parallel sides are unconstrained. The semi-rigid frame utilizes cylindrically shaped hardware (i.e., bolts, rivets, studs, etc.) to hold the sheet or laminate. The semi-rigid frame is designed, via section and material properties, to flex and hinge about fixed mounting points along the length of the frame.
