Latest Patents

One of Donovan's latest patents is titled "Apparatus and methods for refinishing a surface in-situ." This invention features a self-contained, portable apparatus designed for precision grinding operations on metal disks, which can be as large as 54 inches in diameter. The apparatus can be securely attached to the disk's surface and leveled using precision leveling adjusters. During operation, these adjusters are turned in precise increments to set the depth of cut, while the grinder rotates on an arm about the disk's center, utilizing a hydraulically driven speed reducer, rotor, and bearing assembly. Additionally, the invention includes a dressing assembly that performs dressing-truing on a vitreous wheel while in the grinding position, allowing for precise adjustments of up to 0.00125-inch increments.

Another significant patent by Donovan is the "Continuous X-ray analysis for meat blending system." This method and apparatus enable the formulation of meat blends to achieve a desired fat percentage by continuously measuring the fat content in meat streams in a non-destructive manner. The system blends the streams into the desired formulation, despite the non-uniform consistency and density of the meat. A sensor continuously monitors the meat streams, allowing for real-time corrections. Fat percentage measurements are obtained by passing a beam of polychromatic X-rays through the streams and measuring both the incident and attenuated beams.
