Latest Patents

One of his latest patents is a "Method of sealing holes in the ground." This invention relates to an apparatus designed for grouting holes to prevent contamination from spreading within the ground. The grouting apparatus is specifically adapted to follow the previously formed hole, ensuring that it does not create a separate hole during the grouting process. When the apparatus reaches the bottom of the hole, it expels grouting material to fill the vacated space. The apparatus consists of multiple tubular segments connected to form a pipestring, with a tip assembly that includes a pointed tip and ports for the grouting material.

Another notable patent is the "Shaft cleaning and decontamination apparatus." This device is designed to clean and decontaminate rods and shafts used in downhole remediation tasks. It effectively scrubs, washes, rinses, and dries the outer surface of the rods while recovering wash and rinse fluids. The device also features a variation that recycles rinse fluid for use as wash fluid, promoting fluid conservation in the field.
