Latest Patents

Popov’s listed patent, “Self-igniting long arc plasma torch,” describes a torch with a hollow electrode, an isolated plasma tube, and a plasma outlet tube arranged to create two plasma gaps. When voltage is applied, plasma forms across both gaps and spreads until it becomes a continuous, self-sustaining arc. The design also meters plasma gas on both sides of the electrodes to steer the arc attachment along the hollow electrodes, helping reduce surface wear and increase electrode life. The supplied information lists 1 patent for Popov.

Career Highlights

Popov’s documented innovation focuses on plasma-torch design, particularly reliable arc ignition and improved electrode durability. He is associated with Oaks Plasma, LLC.

Collaborations

Popov’s listed coworkers include Alexander Filippovich Rutberg and Philipp Grigorevich Rutberg. The supplied information identifies them as coworkers but does not specify their roles in developing the patent.

Conclusion

Sergei Dmitrievich Popov’s listed patent presents a plasma-torch design that combines self-sustaining arc formation with gas-based arc steering to reduce electrode wear and support longer service life.
