Latest Patents

One of Fetheroff's latest patents is an O-ring inspection method. This method provides a way to inspect a resiliently deflectable O-ring that tends to distort under its own weight. The O-ring is placed on a transparent support member with its central axis in a vertical orientation. Light is directed toward the O-ring, causing it to cast a shadow that can be measured to determine its diametral measurements and thickness. Additionally, the method allows for the detection of surface flaws by analyzing variations in reflected light as the O-ring is rotated.

Another notable patent is related to an airfoil used in turbine engines. This invention involves an apparatus that applies a thermal barrier covering to the airfoil. The airfoil is held by a gripper assembly while a spray gun applies the covering. A sensor detects the thickness of the covering, and a control apparatus ensures that the desired thickness is achieved with high accuracy, despite any process variations.
