Preferably, the diaphragm carries, associated to it, a further diaphragm, which, in conditions of fine dispensing, comes up against the first diaphragm, so as to achieve, by the effect of the common vibratory motion, an action antagonistic to the formation of aggregates or micro-aggregates in the material to be delivered.

Abstract: A conveyor system for moving flowable bulk material is equipped with a funnel (12) that has a circular funnel inlet (13) formed by a cylindrical wall section (16′) and an orthogonal funnel outlet (14) formed by eight funnel walls (18; 17, 17A; 17′, 17″) connected at one end to the cylindrical wall section (16′) and forming at the opposite end the orthogonal funnel outlet (14). Four walls (17, 17A; 17′, 17″) of the eight funnel walls are flat or plane and form funnel side or lateral walls. The remaining four four walls (18) have a curved cross-section and form funnel corner walls which interconnect the funnel lateral plane walls. The eight funnel walls are substantially longer in the axial direction than the cylindrical wall section (16′). The corner walls (18) and the lateral plane walls have approximately the same axial length (H≈H′). The eight funnel walls cooperate in avoiding clogging of the bulk material as it flows through the funnel.

Abstract: The present invention is directed to the remote operation of an auger attached to a portable unit for storing and transporting particulate matter.

Abstract: A screw conveyer for conveying metal turnings from a machining operation. The chip screw conveyor includes an auger-like screw configured to move metal turnings in a given direction. The conveyor includes a tubular housing and an input chute defining an input opening. A secondary feeder arm is pivoted to the conveyor housing. The arm is pivoted out of the way in direction when agglomerated scraps/chips are dumped threw input opening into the input chute. Once the chips are dumped in place, the arm is allowed to rotate downwardly to press on the top of the agglomerated scraps/chips. This prevents the chips from "bridging" between the sides of the input chute and prevents the scraps from "balling" or rolling on top of the screw in a manner that makes the screw ineffective. The arm creates sufficient force to press the scrap into engagement with the flutes of the screw.
