The invention relates to a chute for articles, in particular packages and/or consignments, having a chute base for the article to slide down, having at least one storage installation, preferably assigned to the lower end of the chute, for the articles that have slid down along the chute base, wherein the storage installation is configured to be adjustable, in particular pivotable, from an upper receiving position for receiving the articles sliding down the chute into a lower discharging position for discharging the received articles, and back again.

An oscillatory feeder operable to convey a flowable solid material has a tubular body and a displaceable body segment. The tubular body has at least one first end, at least one second end opposite the first end and a displaceable body segment between the first and second ends. The displaceable body segment has a first fixable location positionable at a first fixed location and a second fixable location positionable at a second fixed location. The actuator is attached to the displaceable body segment and controllable to cause selected displacement of the body segment and attached actuator and corresponding selected flow of solid material within the displaceable body segment in a feed direction extending generally from the first end to the second end.

A flexible funnel element attachable to a holder funnel element to form a funnel section of a material guide chute. The funnel elements include releasable connections to able the flexible elements to be interchanged at the holder elements when worn. Due to the modular construction of the funnel sections, the guide chute has component parts of different materials such that selected components may be optimized for wear resistance and maintaining the free flow of material through the chute.

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.

An apparatus configured for an outlet of a load out silo provided for dispensing proppant from the silo into a storage container. The apparatus comprises a diffuser spout having a housing configured for securing the diffuser spout to the silo outlet and a diffuser element including a first end disposed in the housing, a second end terminating below the housing and a conical sidewall extending between the first and second ends. Flanges extend from the housing for securing the diffuser element thereto.
