Abstract: A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

Abstract: An insulated and logistics track construction for the side and end walls of a refrigerated vehicle includes an exterior metal sheet attached to a plurality of vertical posts that are horizontally spaced. An interior sheet of fiber reinforced plastic (FRP) is spaced from the exterior sheet and attached to the vertical posts by a logistics track attached to each post with the FRP interior sheet captured between the logistics track and post. The logistics track is shorter than the posts, thereby leaving portions of the FRP interior sheet above and below the logistics tracks unattached and unrestrained by the posts.

Abstract: This application is concerned with food packages made from sheet or film into the forms of heat sealable pouches, bags, or covered trays in which the food product is placed, the package sealed, and the packaged food processed in a pressure cooker or retort to permit the packaged food to be stored without refrigeration. Certain food products can be rendered commercially sterile by hot filling the package at temperatures below boiling to permit storage for long periods without refrigeration. While still in the sealed package of the present invention, the consumer can heat or cook the food by immersion in boiling water or by microwave oven. The sheet or film is a multilayer construction wherein each layer performs specific functions and the choice of materials for the layers is interdependent to provide a film structure having all desired properties at the least cost.
