His work notably focuses on advancements in tire inspection technology and hose manufacturing processes, showcasing his dedication to improving industrial standards.

Latest Patents

Dugger's most recent patents include a powerful method and apparatus for non-destructive inspection of tires. This innovative technique employs pulsed through-transmission ultrasonic technology to assess the internal structure of a tire wall without damaging it. The system allows for inspection through the walls of a rotating, inflated tire. The automatic movement of ultrasonic transducers during inspection optimizes the distances from the inner and outer tire wall surfaces. Furthermore, these transducers retract into a protected space during tire mounting and demounting, ensuring safety and functionality.

Another notable invention is a hose building machine designed to produce reinforced industrial hoses for transporting liquids and various solids. The machine wraps multiple layers of different materials, including uncured resin, around a rotating mandrel to create a laminated structure. This structure can be cured in place, enhancing efficiency and effectiveness. The coordinated movement of a carriage alongside the mandrel feeds the layers seamlessly, maintaining precise control over the angle and pitch of the material layers. This automated system compensates for the changing diameter as the laminations progress, facilitating the production of high-quality industrial hoses.
