Latest Patents

Pinault’s listed patents describe closely related approaches to coating tubular articles with solid particulate powder.

“Method and apparatus for coating articles” describes intermittently conveying powder from a fluidized bed through a supply line using a venturi pump and air amplifier. Constantly operating air diffusers and electrostatic charging help deliver powder to the tube’s interior surface. A collection shroud near an open end uses regulated vacuum to capture overspray.

“Method and apparatus for coating the interior surface of hollow, tubular” describes a similar system. It combines intermittent powder delivery, air diffusers, and electrostatic charging, while a vacuum-equipped shroud collects excess powder near an open end of the article.
