Patents by Inventor Carmelo Sunseri

Carmelo Sunseri 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).

  • Process for the production of an anode for an electrolytic capacitor, anode produced by such process, and capacitor having such anode
    Patent number: 6452783
    Abstract: An anode for an electrolytic capacitor includes aluminum foil as a substrate. On the aluminum foil is an alloy including aluminum and a further metal whose oxide has a higher dielectric constant than aluminum oxide. This alloy increases the surface roughness and is in vapor deposited in vacuum in several process steps at different angles of incident. A porous layer thereby is formed and a subsequent anodic oxidation is carried out.
    Type: Grant
    Filed: October 25, 2000
    Date of Patent: September 17, 2002
    Assignee: Becromal S.p.A.
    Inventors: Giovanni Pietro Chiavarotti, Francesco Di Quarto, Monica Santamaria, Carmelo Sunseri

  • Solar collector and method for production thereof
    Patent number: 6003509
    Abstract: A solar collector for absorbing solar energy and for conversation thereof into thermal energy includes an aluminum foil. One side only of the aluminum foil is blackened to an extent such that it will absorb solar energy, preferably to an extent approximating a black body. The blackening is achieved by subjecting the one surface of the aluminum foil to an electrochemical surface etching treatment.

  • Method of use of an aluminum foil
    Patent number: 5695628
    Abstract: The use of an aluminum foil is proposed for the chemical reduction of fluid and/or gas-like components, like CO.sub.2, and/or as a detector for electromagnetic radiation, e.g., in the ultra-violet spectrum. In this process the aluminum foil is subjected to a surface treatment which increases the surface coarseness. The coarse aluminum foil is placed as a negative electrode in an electrolyte bath containing the fluid and/or gas-like components which are to be reduced, thereby causing the aluminum foil to have a potential voltage. The coarse aluminum foil containing a potential voltage in the electrolyte bath is subjected to a photo emission process, e.g., placed under electromagnetic radiation which must be established, and the photo electric current is measured.
