Abstract: A compact, portable carrier for a flexible bag containing a comminuted material and having a bottom discharge spout, including a frame structured to encompass such bag and attach such bag in suspended relation thereto, be transported to a spaced site and be operated to jostle the material contained in such suspended bag to facilitate the discharge thereof through the spout thereof.

Abstract: A system including a receptacle having an inlet for receiving a poke material therethrough and a carrier for supporting a flexible bag with a closable discharge spout, containing a bulk material to be deposited in such receptacle, and means operable upon a bag loaded with bulk material being supported thereon such spout being aligned with such receptacle inlet and such spout being opening for jostling such bag to enhance the discharge of material through such spout into such receptacle, wherein such carrier and such receptacle are provided with cooperating configurations facilitating the positioning of such carrier relative to such receptacle with said bag spout aligned with such receptacle inlet.

Abstract: A system for pneumatically conveying metered amounts of a bulk particulate material comprising a first conduit formed of a gas permeable material having a material inlet and outlet, a second conduit formed of a gas impermeable material encompassing and spaced from said first conduit, and means for intermittently supplying a fluidizing gas under pressure to the plenum between the first and second conduits.

Abstract: A rope assembly for a mechanical bulk material conveyor generally consisting of a continuous rope adapted to be trained about a pair of sprockets within the conveyor, a rope ends connecting flight and a plurality of intermediate flights secured to and spaced along the rope at intervals, each of such intermediate flights including a ferrule having a tubular section receiving a portion of the rope therethrough and being firmly secured thereto and an annular flange section, a disc member having an opening receiving a portion of the rope therethrough, a boss member having an opening receiving a portion of the rope therethrough, the opening in at least one of the disc and boss members having a first enlarged section receiving a portion of the ferrule tubular section therein and a second enlarged section receiving at least a portion of the ferrule flange section therein, and means for firmly securing the disc and boss members together with the ferrule interposed therebetween.

Abstract: An apparatus into which particulate material may be charged for further handling generally includes a housing having a support wall including a primary inlet through which particulate material may be charged, producing portions of settling and airborne particles of such material, and at least one secondary inlet, and an outlet through which the particulate material may be discharged, a filter unit having an inlet communicating with the interior of the housing and means for producing an airflow from the primary and secondary inlets through the filter unit whereby ambient air will be caused to be drawn through the primary and secondary inlets and the filter unit, entraining airborne particles outside and within the housing which further are caused to be removed from such airflow by the filter unit, dislodged therefrom and be discharged through the housing outlet.
