Publication number: 20250083180Abstract: Techniques for comparing test coatings against a standard coating using a unique user interface having a particular visual layout designed to facilitate the comparison process. Generally, the user interface is specially tailored to facilitate a comparison and calibration process in which the test coating is analyzed to determine whether it aligns with a standard coating. A coating identification computer system receives digital measurements of coatings and displays renderings of those coatings. The system also displays a rendering of a standard coating. The system determines match statuses or calibration states between the coatings and the standard coating.Type: ApplicationFiled: July 26, 2022Publication date: March 13, 2025Applicant: PPG Industries Ohio, Inc.Inventors: Mark David Lewis, Angela Kathleen Staufer

Patent number: 11421331Abstract: Apparatus for seawater acidification including an ion exchange, cathode and anode electrode compartments and cation-permeable membranes that separate the electrode compartments from the ion exchange compartment. Means is provided for feeding seawater through the ion exchange compartment and for feeding a dissociable liquid media through the anode and cathode electrode compartments. A cathode is located in the cathode electrode compartment and an anode is located in the anode electrode compartment and a means for application of current to the cathode and anode is provided. A method for the acidification of seawater by subjecting the seawater to an ion exchange reaction to exchange H+ ions for Na+ ions. Carbon dioxide may be extracted from the acidified seawater. Optionally, the ion exchange reaction can be conducted under conditions which produce hydrogen as well as carbon dioxide. The carbon dioxide and hydrogen may be used to produce hydrocarbons.Type: GrantFiled: April 4, 2016Date of Patent: August 23, 2022Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Felice DiMascio, Dennis R.

Patent number: 10450661Abstract: A method for using an electrochemical cell to continuously acidify alkaline water sources and recover carbon dioxide with simultaneous continuous hydrogen gas production. The electrochemical cell has a center compartment, an electrolyte-free anode compartment having a mesh anode in direct contact with an ion permeable membrane, an endblock in direct contact with the anode where the endblock provides a gas escape route behind the anode, an electrolyte-free cathode compartment having a mesh cathode in direct contact with an ion permeable membrane, and an endblock in direct contact with the cathode where the endblock provides a gas escape route behind the cathode. Current applied to the electrochemical cell for generating hydrogen gas also lowers the pH of the alkaline water to produce carbon dioxide with no additional current or power.Type: GrantFiled: June 6, 2017Date of Patent: October 22, 2019Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Felice DiMascio, Heather D.
