Pressurized apparatus for discharging powdered reagent from a shipping container

摘要

A shipping container having powdered reagent therein is mounted atop a transition chamber disposed on suitable support structure so that the contents of the shipping container may be discharged through a valve thereon and through the transition chamber into a dispenser vessel supported by weighing means suspended from the support structure and interconnected with the transition chamber by a yieldable coupling arranged to provide a fluid-tight connection between the transition chamber and the dispenser vessel irrespective of the weight of the contents of the dispenser vessel and a pair of conduits controlled by a common valve are arranged to supply pressure fluid such as an inert gas from a source under pressure into the transition chamber and into the shipping container in coordination with the mounting of the shipping container on a part of the transition chamber.
