摘要

A method of removing an article from a chamber having a reduced pressure therein by connecting the chamber to a pool of liquid by a barometric leg is disclosed. The method provides a conveyor in said barometric leg and allows said article to float up into engagement with said conveyor so that the force exerted on the article by the conveyor moves the article down into the pool of liquid and out into the atmosphere.
