Latest Patents

One of Seigeot's latest patents is a method and device for pumping a process chamber. This innovative pumping device is designed to connect to a process chamber and includes a dry primary vacuum pump along with an auxiliary pump. The auxiliary pump is strategically mounted to bypass a check valve on the vacuum pump. The device features a first valve connected to a purging device for the dry primary vacuum pump and is intended to connect to a gas supply. Additionally, a second valve device is mounted to bypass a check valve upstream from the auxiliary pump. The controller of this device is configured to manage the first and second valve devices based on the operating status of the process chamber, ensuring optimal performance when the chamber operates at ultimate vacuum.

Another significant patent by Seigeot involves variable speed primary pumping in a tracer gas leak detector. In this system, a mass spectrometer is connected to the aspiration side of a secondary pump, which in turn is linked to a primary pump driven by a rotational drive system. This system allows for the variation of the primary pump's rotation speed, enabling faster pre-evacuation before testing, detecting larger leaks, and compensating for high levels of outgassing. This innovation also helps in eliminating helium background noise from the primary pump, enhancing the overall sensitivity of the leak detection device.
