Patent number: 10858742Abstract: Compositions and methods for inhibiting corrosion of metallic surfaces in contact with an aqueous medium such as copper, copper alloy, and steel surfaces of an open recirculating cooling water system. In certain embodiments, an aromatic triazole having an anionic substituent bonded to a nitrogen atom of the triazole (ANST) is used as the corrosion inhibitor. In other embodiments, the corrosion inhibitor is a reaction product of an aromatic triazole and an aldehyde (ATA).Type: GrantFiled: May 10, 2017Date of Patent: December 8, 2020Assignee: General Electric CompanyInventors: Muthukumar Nagu, Amutha Nagarajan, Paul Robert Frail, Edward Joseph Urankar

Patent number: 8137746Abstract: This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.Type: GrantFiled: August 5, 2004Date of Patent: March 20, 2012Assignee: The Procter & Gamble CompanyInventors: Mattias Schmidt, Axel Meyer, Renae Dianna Fossum, Bruno Johannes Ehrnsperger, Stephen Allen Goldman, Michael Divo, Edward Joseph Urankar
