Process for Preparing Steel Sheet for Enameling U.S. Patent 5,766.374. June 16, 1998 1. Guillot et al., assignors to Sollac, Puteaux, France

A process for manufacturing an article made of direct-on enameled steel sheet, which process comprises a forming opera- tion. ;I surface preparation operation in which a steel sheet surface is pickled under conditions that remove at most IS gms of

steel per square meter of sheet surface and then subjected to amorphous phosphatiza- tion with a solution comprising less than 0.05 g/L of nickel and molybdenum under conditions that form a coat of at least 0.2 g/m’ cm the surface followed by nickel plating. and an enameling operation, wherein the forming operation is carried

out after pickling and after amorphous phosphatization.

Jaynor’s Gold Digger: Makes solid gold for 29 an ounce.

No more refining of solutions or burnable resins. Just send metal. Like all great ideas, the Jaynor Precious Metal Recovery System-the Gold Digger-is simplicity itself. Instead of using bulky resins, the 38-lb TV-sized Gold Digger attaches to your dragout tank and plates the metal out on a cathode panel. The metal is 80% to 90% pure. Start mining solid gold! JAYNOR can design and build a custom Gold Digger to fit your specific needs.
