ABSTRACT:
This invention is a transfer system for controlling and initiating the flow of metered amounts of materials. The aforementioned materials may be radioactive ash, radioactive calcined salts, cement, flour, or pharmaceuticals. The apparatus of this invention comprises: a vertical non-converging conduit which acts as a storage hopper; a stationary platform located at the downward end of the conduit to allow the radial outward flow of the material; a translatable hollow piston that acts externally but coaxially to the conduit and platform to interrupt the radial flow of material; a hopper located below the platform for accepting the material; and a housing that encloses and supports the hopper and platform and provides a dust tight seal around the apparatus of this invention.
