Patents by Inventor Emilio Zioni

Emilio Zioni has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for applying a coating to a metal substrate or repairing a coating applied to the same
    Patent number: 6387440
    Abstract: The invention describes a method for applying an electrocatalytic or a protective coating to a metal substrate or repairing a damaged area of the same, consisting in a thermal treatment of a precursor of said catalytic coating by means of a hot air jet from a blower. The temperature of the substrate is locally controlled by means of surface temperature sensors or by an infrared measuring system. The metal substrate may be an exhausted electrode structure, in which case the reactivation is easily carried out at the plant site without any need of sending the structure to the producer. The method of the invention is particularly useful for reactivating anodes for oxygen evolution as it permits to avoid the risky procedure of detaching the anode from the current conductor.

  • Electrode for use in membrane electrolyzers
    Patent number: 5824201
    Abstract: The invention concerns an improved electrode particularly useful for electrochemical processes forming gaseous products. The electrode is made of a composite structure comprising a shaped sheet having a profile of the "venetian blind" type, which provides for ensuring the necessary stiffness and improved local fluodynamics, and a mesh having the same "venetian blind" profile, provided with an electrocatalytic coating. The mesh is fixed by spot welding to the sheet in order to have the two profiles substantially coincident.
