Embodiments of the present disclosure a system for capturing proppant dust particles when positioned at a fracking operation site including a proppant delivery assembly to receive one or more containers having proppant stored therein. The system dispenses the proppant from the one or more containers and delivers the proppant to other fracking operation equipment. Moreover, the system includes a dust collection assembly positioned proximate and associated with the proppant delivery assembly to capture dust particles released by movement and settling of the proppant when being dispensed and delivered by the proppant delivery assembly. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure to fracking operation site personnel.

A wear resistant funnel sheet element for a material guide chute includes first and second edges located at a tapered angle from each other. Interlinking fastening features are provided in order to mate the respective edges of at least one of the wear resistant funnel sheets to form a funnel element. The sheet element may be a molded flat piece of a rubber material, which serves as an interchangeable wear part on a material guide chute.

A temporary, non-fixed partitioning system includes a common assembly bracket that can be readily assembled with a wall panel formed of various standard dimensioned building supplies. The wall panels may include a standard door slab, a standard window sash, standard dimensional lumber, a peg board, a chalk board, a whiteboard, a corrugated cardboard panel, a foam board, a gator board, a fiberglass panel, a cork panel, a plastic panel, an upholstered panel, a wood panel, and an acrylic-based or silica-based glass panel, and may also be suitable for receiving custom or desired printing of designs, indicia or other nomenclature. The partitioning system could be provided in a kit form with a plurality of common assembly brackets and wall panels, which are reconfigurable for a variety of uses such as co-working space, trade show booths, or lobby displays.

A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute. The hood assembly includes a curtain extending about a perimeter of the hood assembly and downward therefrom to at least partially define the volume of air being removed by the hood assembly.

In one example, a pallet conveyor for a printing system is described, having a track, a pallet to support a print substrate and move on the track, and a vacuum mechanism to selectively apply a vacuum at the pallet. A boundary of the vacuum applied at the pallet is synchronized with an edge of the print substrate.

A collapsible chute for conveying materials with a tubular main body of flexible material with an entrance opening, an exit opening, and a body portion between the entrance and exit openings. A first reinforcing band is fixed to surround the body portion adjacent to the entrance opening, and a first plurality of loops is spaced along the first reinforcing band. A second reinforcing band is fixed to surround the body portion spaced from the first reinforcing band and spaced from the exit opening, and a second plurality of loops is spaced along the second reinforcing band. A third reinforcing band can be fixed to surround the body portion between the first and second reinforcing bands, and a third plurality of loops is spaced along the third reinforcing band. A method for debris removal comprises affixing the entrance opening of the body portion of the main body to an opening of a building structure and evacuating debris through the main body of the collapsible chute.

A system and method for storing and sequencing a plurality of luggage items. The system includes containers with vertically stacked shelves and an automatic guided vehicle releasably attachable to the containers for transporting a container between a first predetermined area and a loading area with a loading assembly to move a luggage item from an entrance conveyor onto one of the shelves of the container. The containers may include wheels for being manually moved. A transport vehicle is provided for moving a plurality of containers together. The method includes determining a grouping criterion of the luggage item and sorting and sequencing luggage items onto containers according to the grouping criterion. Different embodiments of the loading assembly are provided with one using a packing automated vehicle and another using stacked platform conveyors. Several grouping criteria are provided which may depend on processing requirements of the luggage items.
