A tank with a door locking mechanism for use in bioprocessing, and methods of using the door locking mechanism, is provided.

A lining method includes fixing a backing strip in a frame shape to a concrete surface of already-placed concrete so that the backing strip protrudes from the concrete surface; disposing a filler inside a frame of the backing strip; making edges of a plurality of lining plates butt against each other at a position of the backing strip to cover the backing strip and the concrete surface; and joining the edges of the lining plates by seal welding.

A flexible tank (10, 110) for transporting fluids in a transportation container (12) is described, the flexible tank (10, 110) defining a tank (10) volume for containing a fluid. The flexible tank (10, 110) comprises at least one mixing member (146, 46) enclosing a fluid pathway (160, 60) extending across an interior surface (144, 44) of the flexible tank (10, 110), the flexible tank (10, 110) further comprising at least one inlet valve (140, 40) configured to allow the passage of fluid from outside said flexible tank (10, 110) into said fluid pathway (160, 60). The mixing member (146, 46) further comprises at least one aperture (154) such that the inlet valve (140, 40) is in fluid communication with the tank (10) volume via the fluid pathway (160, 60). An intermodal container (12) comprising the flexible tank (10, 110) and a method of mixing a fluid with the tank (10) are also disclosed.

This patent pertains to secondary containment systems. One implementation includes a support assembly that includes an elongate post member and a stabilization plate. In one instance, a stabilization plate is mounted on the elongate post member to reduce movement of the elongate post member when the stabilization plate is embedded in the ground. Another implementation includes a panel splice assembly including reinforcing members that secure overlapping, corrugated panels.

Provided is an aircraft water tank with a lid joined to an opening portion via internal threads and external threads. An O-ring is compressed so that the opening portion is liquid-tightly sealed, which forms a sealed water storage space in a tank body. The portion of the lid that compresses the O-ring is a corner portion formed by an end surface of an annular plate portion and an outer peripheral surface of a tube portion. The portion of an inner liner that compresses the O-ring is a portion of the inner liner attached to an inclined surface. An end portion of the inner liner attached to the surface of a bulging portion is located outside the water storage space.

A kit from which a thermally insulated shipping container may be assembled and a thermally insulated shipping container assembled from such a kit. The kit includes an outer shell and four flat stock vacuum insulated panels, each with three articulating sections foldable to form 3-dimensional C-shaped units. The panels are nestable pairs effective for lining a lower portion of the outer shell with a first nested pair and lining an upper portion of the outer shell with a second nested pair so as to form a fully enclosed insulated payload chamber within the outer shell.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

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.

An aircraft water tank includes a conical surface of a skirt portion and a conical surface of an inner liner attached together using an adhesive, with an identical adhesive used in forming a fiber-reinforced resin layer on the inner liner via a filament winding method. When attaching with the adhesive, the adhesive is expelled at the outer circumferential edge of the skirt portion from between the conical surface of the skirt portion and the conical surface of the inner liner. Reinforcement fibers are applied on top of the protruding adhesive, and the adhesive impregnates into the reinforcement fibers. The protruding adhesive and the reinforcement fibers form a reinforcing member which connects a uniform stress surface of the skirt portion to a uniform stress surface of the inner liner located radially outward of the skirt portion.
