Title: Innovations and Contributions of David L Burk
Introduction
David L Burk is a notable inventor based in Pittsburgh, PA, with a remarkable portfolio of six patents. His work primarily focuses on advancements in manufacturing processes and systems that enhance efficiency and accuracy in metal workpieces.
Latest Patents
Among his latest innovations is the "Slab Surface Contour Monitor." This system is designed to create an image of the surface contours of a metal workpiece, such as a continuous cast slab. It utilizes a sheet of single frequency, planar light directed at the workpiece's surface, along with a video camera that captures the light's reflection. When the surface is flat, the camera senses a straight line, while irregular surfaces produce a nonlinear line. The camera generates a two-dimensional image, which is processed to extract various quantitative parameters, ultimately displayed on a video monitor and printer.
Another significant patent is the "Insulating Heat Retention System and Method." This invention provides an air-free system for processing heated articles, featuring upper and lower heat shields that create a substantial infiltration air-free enclosure. The heat shields are made of high purity 100% ceramic fiber, designed to prevent air from entering the enclosure while maintaining close proximity to the heated articles.
