Latest Patents

One of her latest patents is the "Sub-atmospheric gas delivery method and apparatus." This invention provides an apparatus for containing and delivering hazardous gases at sub-atmospheric pressure from a pressurized container. The design includes a valve body in sealed communication with an outlet orifice of the pressurized container, ensuring safe gas delivery. The apparatus features a pressure regulator that responds to sub-atmospheric pressure, allowing gas to flow only when the downstream pressure is at or below a pre-set level. Additionally, a high-pressure shut-off valve is integrated into the system to enhance safety.

Another notable patent is the "Gas control device and method of supplying gas." This modular gas control device is designed for use with compressed gas cylinders. It consists of a primary module and a secondary module, which work together to manage gas flow efficiently. The primary module includes a pressure reducing mechanism that provides gas at a lower pressure than that in the container, while the secondary module incorporates functional components for measuring and varying gas flow parameters.
