Title: The Innovative Mind of Donald A. Toon
Introduction
Donald A. Toon, an accomplished inventor based in Burlington, CA, has made significant contributions in the field of groundwater sampling technology. With an impressive portfolio of 9 patents, his inventions are primarily focused on enhancing groundwater extraction methods.
Latest Patents
Among his latest patents are two remarkable innovations. The first is a groundwater sampler designed for extracting samples from a borehole. The innovative design features a down-hole fixture with a check-valve located at the foot of the borehole. The sampler is lowered into the borehole, and pressing down on the sampler opens the check-valve, allowing groundwater to flow into the sampler. A plastic tube runs from the sampler to the surface, transmitting the necessary force required to operate the down-hole valve.
The second innovation is a plugging system for boreholes, aimed at preventing unrestricted water flow within an open borehole. This system utilizes a hose made of stretch elastic rubber. Once the hose is inserted into the borehole, it is filled with water from the surface, causing it to inflate and effectively plug the borehole. This invention is particularly useful in conjunction with multi-level sampling apparatus, where lengths of the hose can be employed to separate the borehole at various sampling ports. The mechanical support for the hose is provided by stiff plastic tubing that runs inside the hose between couplings.
