Latest Patents

Vettraino’s listed patent, “Vacuum Assisted Nut Drop Test,” describes a repeatable method for evaluating materials such as paint, coatings, and tape. The apparatus uses an elongated tube with a funnel to guide test pieces, such as metal nuts or small rocks, onto a planar test panel. After impact, the pieces fall into a holding container. A vacuum connected through conduits and a separator removes the pieces from the container, allowing them to be collected and the test to be repeated. Vettraino is credited with 1 patent.
