A turbine system (10) has a turbine (12) that uses an aeromatic hydrocarbon as a working fluid (18). The turbine discharges the fluid in vapor form against a boundary layer on the inside of a rotor (166) where it condenses as it loses its energy. The outside of the rotor is formed to define chambers which are divided into suction and discharge or pressure cavities by stationary and rotating seals. Apertures (236-237) connect the boundary layer to the pump chambers and apertures (158-160) are positioned as discharge ports so that as the rotor rotates, it also pumps the working fluid into a closed loop system in which it is reheated and reintroduced into the turbine through a nozzle …

Why it's free to use
- Filed July 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 14, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 14, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
