Latest Patents

One of Fortier's latest inventions is the electronically controlled vacuum pump. This innovative vacuum system comprises an integral assembly that includes a vacuum pump with a drive motor, a purge valve, a roughing valve, and an electronic control module. The system features both a cryogenic vacuum pump and a turbomolecular vacuum pump. The control module is equipped with a programmed processor that manages the motor and valves, allowing for user programmability to establish specific control sequences. Notably, the electronic control module is removable and connects to other devices through a common connector assembly. In the turbomolecular pump system, the proper introduction of a purge gas is detected by monitoring the current load on the pump drive or foreline pressure. The system is designed to test the purge gas status by closing and then opening the purge valve while monitoring drive current or pressure. After a power failure, the controller ensures the normal operation of the turbomolecular pump, provided the pump speed remains above a threshold value. If not, the vent valve opens, requiring a start-up sequence. During shutdown, power to the pump drive motor is discontinued, and the vent valve is opened before closing the roughing valve.
