The mighty Led Zeppelin, coming off the back of an insanely successful 1973 US tour that packed 56,800 worshippers into Tampa Stadium in Florida and in so doing broke the Beatles' attendance record. The news that the group's next release will be a double album does not fill the hipper critics with unbridled enthusiasm.
Phosphate Inhibitor Addition. This method of corrosion control is based on the theory that the addition of phosphate to a finished water will result in the formation of low-solubility lead-phosphate complexes on interior pipe surfaces.The protective layer acts as a barrier to corrosion, reducing dissolution of lead into the water.hosphate Inhibitor Addition.

1. Field of the Invention. This invention relates to zinc phosphate coatings for metal surfaces and a process for phosphatizing a metal surface with acidic aqueous phosphate solution. The invention is applicable to a variety of substrates including cold rolled steel (CRS), zinc alloys and aluminum.2.atents. Zinc phosphate coatings for metal surfaces and phosphating process. Concentrates containing (a) hydroxylamine sulfate and (b) zinc, nickel, manganese and phosphate ions are formulated into aqueous coating solutions for treating metal surfaces, including ferrous, zinc and aluminum surfaces....
