A proportioning device is provided for use with a sealable chamber for unloading pulverulent material from a bulk transport system which includes a fluid inlet conduit having one terminal end in communication with the chamber for transmitting fluid into the chamber for fluidizing the pulverulent material therein, a fluid outlet conduit having one terminal end in communication with the chamber for transmitting fluidized solids therefrom. The proportioning device is in communication with the other terminal end of the fluid inlet conduit and with the fluid outlet conduit and is adapted to be connected to a source of fluid for supplying the fluid to the fluid inlet conduit and the fluid outlet conduit, the fluid proportioning device being responsive to the fluid pressures in the fluid conduits for proportioning the fluid into the fluid inlet conduit and the fluid outlet conduit to maintain a predetermined ratio between the fluid pressures in the fluid inlet conduit and the fluid outlet conduit.

Proportioning device

An unloading system for granular lading comprising a hopper having four cells each with a discharge opening in the lower portion thereof, a discharge tube below the hopper and communicating with each of the openings, two part-tubular sliders within the discharge tube in general longitudinal arrangement with each adjacent to two of the openings, each of the sliders being independently shiftable longitudinally within the discharge tube between a storage position and one of two discharge positions, and a handle for each of said sliders extending to one end of the hopper for controlling the slider from the one end of the hopper; there also is disclosed an end cap for the discharge tube securable thereto and holding the handles in the storage positions thereof, a slide rod being provided on the hopper to hold the end cap when it is disengaged from the discharge tube.
