A liner floor for use in a container liner is provided. The liner floor includes a floor portion arranged between a distal end and a proximal portion and the floor portion is configured for being arranged on a floor of the container. The floor portion includes a plurality of stacks of folded sections. The stacks are folded such that a top fold of one stack is connected to a bottom fold of a proximal neighbouring stack. A weight of the folded sections varies along the floor portion with each of the folded sections having at least the same weight as a proximal neighbouring folded section. Also provided are methods for unloading cargo from a container including a liner, and methods and apparatuses for loading cargo into a container.

In an aircraft water tank, a mouthpiece is attached to an inner liner, and an overflowing adhesive is received in an annular missing portion provided to an expanded portion of the mouthpiece through the gap between a skirt portion and the inner liner. Further, a sealant fills the part of the annular missing portion, which is exposed from an end of a plate portion for the expanded portion.

A flexible tank fillable with a liquid having a base and at least one enclosing wall. The base has an upper surface and a lower surface, and defines a plurality of edges and a perimeter. The enclosing wall extends about the base and is attached thereto to, together with the base, define an enclosure. The inner brace assembly comprises at least one inner support member having a base wall attachment side and an encasing wall attachment side. The base wall attachment side is attached to the base spaced apart from the perimeter. The encasing wall attachment side is attached to the at least one enclosing wall spaced apart from the base fold.

A storage silo for storing granular material has a container supported by a base, the container having a roof and at least one side wall for defining a storage space beneath the roof. The storage silo includes: (a) a feed port for receiving the granular material at a feedport height lower than the roof; (b) an auger for moving the granular material toward the roof within the storage space, the auger receiving the granular material via the feed port; and (c) first and second auger motors for cooperatively driving the auger, the first and second auger motors being disposed at opposing ends of the auger. A processor determines power levels for the first and second auger motors to minimize torsional strain on the auger. Granular material can be discharged from a first storage silo into a second storage silo positioned for cascading with the first storage silo.

A self-funneling flexible container may be used with a storage and transportation system to provide an efficient, effective and cost-efficient transfer of material to, from or about a site, for example, a hydrocarbon exploration, recovery, production or operation site. The self-funneling flexible container may comprise one or more bands about the bottom or the bottom and one or more sides of the self-funneling flexible container. The bands have an elasticity such that the weight of material disposed in the self-funneling flexible container transitions the bands to an expanded position. When the material is discharged, the bands transition to a contracted position to form a funnel or chute so that all material may be efficiently discharged. As the funnel or chute is only formed at discharge, the self-funneling flexible container may store more material than traditional rigid containers.

A collapsible storage silo having an expanded configuration includes: (a) a shell for circumscribing storage space and comprising a plurality of concentrically nested tubular members that are collapsible; (b) a lift system operable to slidably expand the plurality of concentrically nested tubular members to place the silo in its expanded configuration; and (c) a mast operable to support the lift system, The mast is pivotable between horizontal and vertical positions relative to a frame. A winch attaches to the mast and a cable extends between the winch and an outermost tubular member to expand the silo such that inwardly and outwardly projecting lips of nested members engage each other and a conical hopper engages an innermost tubular member. A flexible inner liner attaches between an outermost tubular member and the hopper. A collapsible roof has a flexible roof membrane and a plurality of radially extending foldable rib members.

The present invention concerns a foldable modular packaging (1), characterised in that it comprises: at least four panels (10) that can be moved between a folded position, in which the panels (10) are stacked on each other, and an unfolded position, in which the panels (10) form a parallelepiped frame (11) defining an internal volume (12); a flexible inner container (20) suitable for being arranged in said internal volume (12); and an assembly system (30) comprising linking elements (31) forming a pivot link between each panel (10) and at least one adjacent panel (10).

A proppant delivery system for use at a hydraulic fracturing site to prepare a proppant mixture for subsequent delivery to a wellbore at the hydraulic fracturing site comprises two types of proppant storage containers, including silo type and box-like container type each of which normally has a dedicated system to dispense proppant, arranged in an array usually employed in a silo-only delivery system where parallel rows are formed and interrupted by a feed conveyor extending parallel to and disposed between the rows. A support stand carries the box-like container to one side of the feed conveyor with a bottom discharge of this container held at a spaced height above a ground surface.
