A filter assembly includes a filter pad comprising flame resistant viscose. The filter assembly also includes a bonding emulsion. The bonding emulsion may comprise casein resin. The bonding emulsion may additionally comprise acrylic resin. The filter assembly also includes a structural support. In particular embodiments, at least a portion of the fibers are treated with a solution that is fire resistant or fire retardant.

A vertical fluid storage tank including a body extending from a first end to a second end and including a substantially oval-shaped cross-section, a top wall connected to the first end of the body, a bottom wall connected to the second end of the body, at least one access opening positioned on the top wall configured for access to an interior cavity of the body, and at least one discharge valve connected to the body. The storage tank is configured to be arranged in at least two positions. The at least two positions include a first position in which the storage tank is arranged parallel to a surface, and a second position in which the storage tank is arranged perpendicular to the surface. A walkway may be positioned in the interior cavity of the body.

An adapter for a vent system for a cargo container having corrugated panels, has a base portion formed of sheet material, having an outer boundary and an inner boundary, the inner boundary enclosing an area sufficient to accommodate a twelve-inch diameter circle, the base portion shaped to closely conform to geometry of the corrugated panels of the cargo container, an intermediate portion joined in an airtight manner to the inner boundary of the base portion, presenting a surface at a height above an upper extremity of the corrugated geometry of the base portion, and an interface providing a through opening in the surface of the intermediate portion within the area enclosed by the inner boundary of the base portion.

A roof vent system for a grain storage device is disclosed. A roof vent including a lid is operatively connected to the roof panel adjacent the opening. The lid is configured to move between an open position and a closed position. A bias member configured to apply an upward bias force to the lid to automatically move the lid to the open position. A control lever that is movable between an upper position and a lower position. The control lever is operably connected to the lid by a pull. When control lever is moved to the lower position with a force greater than the bias force of the bias member, the lid is moved to the closed position. A sealing member attached to the lid is configured to provide a seal between the lid and the roof panel when the lid is moved to the closed position.

The invention relates to a back-plate for a cooling machine in a reefer container with an improved fan grille, where a grille or grating defines a section formed integral with the back-plate. The grille or grating defined in the back-plate can comprise layers of fibreglass forming the back-plate. The grille or grating can surround holes provided by drilling, cutting or another suitable machining of the back-plate after casting. The grille or grating can be provided by a mesh structure having different mesh sizes. The grille or grating can be provided with a more dense mesh structure in one or more local areas compared to a remaining part of the grille. The grille or grating is provided at an upper part of the back-plate.

A storage device (1) for bulk material intended for powdery materials, includes a flexible container (2) for bulk material and an insulating inner liner (3), of which the surface resistivity is greater than 1.01012, without a static electricity conductive layer and without a static electricity dissipation layer, the inner lining (3) covering the inner walls of the container, the inner lining (3) including micro-perforations that pass there through, distributed over the whole surface of the inner lining (3) in such a way that the breakdown voltage of the inner liner (3) is lower than 4 kV and the breakdown voltage of the wall of the container is lower than 6 kV.

A water storage tank includes: a tank containing water; a roof positioned over the tank; a headspace region formed between the roof and a surface of the water contained in the tank; and a corrosion reduction system. The corrosion reduction system includes (i) a port that enables air to flow out of the water storage tank, and (ii) an active air ventilation system having at least one device configured to facilitate movement of air exterior of the water storage tank into the headspace region. The corrosion reduction system reduces a rate of corrosion of the water storage tank. A method of reducing a rate of corrosion of a water storage tank is also included.

A roof vent system for a grain storage device is disclosed. A roof vent including a lid is operatively connected to the roof panel adjacent the opening. The lid is configured to move between an open position and a closed position. A bias member configured to apply an upward bias force to the lid to automatically move the lid to the open position. A control lever that is movable between an upper position and a lower position. The control lever is operably connected to the lid by a pull. When control lever is moved to the lower position with a force greater than the bias force of the bias member, the lid is moved to the closed position. A sealing member attached to the lid is configured to provide a seal between the lid and the roof panel when the lid is moved to the closed position.

A bulk solids container can include a bag to hold the bulk solid, a rigid base to support the bag, and rods extending up from the base to the top of the bag. The rods provide vertical structural integrity to the sides of the bag. The base can include a sloped upper surface sloping down towards a discharge opening located near the center of the base and aeration openings that inhibit or prevent the bulk solids from clogging the discharge opening during removal of the bulk solids from the bag. When the bag is empty, the bag and the rods can be collapsed and fit on top of the upper surface of the base. The container can be transported back to a fill facility to be reused.
