ABSTRACT:
In apparatus for measuring out pulverulent materials, including a screw rotatably mounted in a barrel having an outlet at one end, the ability of the apparatus to impart a uniform flow rate to materials having poor flow properties is improved by interrupting the thread of the screw between any two circumferentially spaced generatrices of the cylindrical surface thereof and by disposing scraping elements to cooperate with the screw thread.
