His work primarily focuses on pneumatic devices and fluid separation systems, which have significant applications in environmental and industrial settings.
Latest Patents
One of his latest patents is a pneumatic indicator for detecting liquid levels. This device includes a sensor assembly with a bellows receiving chamber and a sensor housing. An elastic bellows within the chamber allows for the detection of liquid levels through axial movement of a connected shaft. A magnet generates a field that moves an indicator ring, providing a visible indication of the liquid level. The design ensures that the dome and indicating ring are isolated from the well contents, preventing fogging and ensuring accurate readings.
Another significant patent is a float-operated pneumatic pump designed to separate hydrocarbons from water. This pump operates based on the density of the fluids involved. It features a displaceable fluid inlet that tracks the water/hydrocarbon interface, allowing for efficient separation. The design includes an outer tube forming an outer chamber and an inner dip tube, which work together to facilitate the separation process. This innovative approach allows for the effective management of fluids in well environments.
