  • Metal-working emulsion reclaiming process
    Patent number: 4357243
    Abstract: A method for reclaiming an aqueous emulsion useful as a metal-working lubricant/coolant which is contaminated with particles of at least one metal comprises contacting the contaminated emulsion with at least one metal solubilizing agent at metal solubilizing conditions to solubilize at least a portion of the metal particles. The thus contacted emulsions have improved suitability as a metal-working lubricant/coolant relative to the contaminated emulsion.

  • Azole-phosphate corrosion inhibiting composition and method
    Patent number: 4134959
    Abstract: The invention disclosed provides a new composition and method for inhibiting corrosion. The present composition is relatively non-toxic, contains no chromates and zinc, and consists essentially of an azole and a water-soluble phosphate in an effective combination. Effective amounts of the corrosion inhibiting composition are used to provide corrosion protection in both ferrous and non-ferrous metals.

  • Boiler water treatment
    Patent number: 4067690
    Abstract: The invention disclosed provides a method for boiler water treatment to retard corrosion due to dissolved oxygen. Hydroxylamine, certain derivatives thereof and their salts have now been found to be highly effective oxygen scavengers for use in boiler water and thereby effect reduction of corrosion resulting from dissolved oxygen.
