A process for imparting a simulated patina appearance to a copper substrate including selecting a colorant having the desired initial patina color tone and producing a noncontinuous layer of the colorant on a surface of the copper substrate to provide the appearance of patination of the desired tone via interspersed spots of the colorant. The remaining portion of the substrate is exposed for natural patination.

Simulated patina for copper

A process for imparting a simulated patina appearance to a copper substrate, and a substrate having that appearance. A colorant having the desired initial patina color tone is employed to produce a non-continuous layer of colorant on the surface of a copper substrate. The appearance of patination of the desired tone is created by interspersed spots of colorant with the remaining portion of the substrate being exposed for natural patination. The interspersed spots of colorant may be produced by screen printing, by spattering, as by spraying, or by mechanical removal of colorant after application to the substrate surface, or a combination. The colorant is preferably a paint and may be applied by non-uniform spraying on the substrate surface. Non-uniformity may be accomplished by varying the volume of colorant sprayed during the application process or by varying the relative movement of the spray and substrate. After application, the colorant provides a simulated patina to the copper substrate surface while allowing the remaining (non-covered) portion of the substrate to patinate naturally.

A process for imparting a simulated patina appearance to a copper substrate, and a substrate having that appearance. A colorant having the desired initial patina color tone is employed to produce a non-continuous layer of colorant on the surface of a copper substrate by roll coating. The appearance of patination of the desired tone is created by interspersed spots of colorant with the remaining portion of the substrate being exposed for natural patination. The interspersed spots of colorant may be produced by screen printing, by spattering, as by spraying, or by mechanical removal of colorant after application to the substrate surface, or a combination.

Apparatus for forming an arch is architectural panels including a drive section and an arching section. Each of the drive section and arching section have at least one roller and cooperating follower with the rollers being adapted to engage the underside of the panel with a groove in the followers accepting side legs of the panel. In a preferred embodiment, two cooperating followers float along a common shaft in association with each roller.

Architectural panel arching device

A storage appliance for use with tubing, pipes and similar items. A generally U-shaped member carries a peg at a distal end of each of its legs and a coupling device at their proximal end. The pegs have a first portion of a generally circular cross section and taper to a rounded point at one terminus. The coupling device has an aperture of the same general cross section as the peg first portion. A storage rack is assembled from the appliances by inserting the pegs of one appliance into the coupling devices of another, the number of appliances used being dependent upon the particular storage requirement. The distal ends of the legs of each appliance are made flat to provide a mating surface for an appliance placed thereon while the tapered pegs allow a cooperation between the pegs of one appliance and the coupling device of another even when the legs of the peg-carrying appliance are spread due to loading or otherwise. The circular cross section of the pegs allow an empty appliance to be pivoted about one of the pegs to fully expose the items stored in the appliance immediately below. The pivoted appliance may be thus stored on the storage rack until it is needed. Further, a storage rack assembled from the appliances of the present invention allows a compartmentalized inventory control.
