Abstract: A cargo container is adapted to transport liquids and, alternatively, solid cargo which comprises a box-like housing having rigid side walls and an expansible vessel for containing the liquids mounted inside the box housing. The expansible vessels include a rigid fixed bottom wall, a rigid top wall extending parallel to the bottom wall, and a flexible impermeable sleeve forming side walls extending between the vessel bottom wall and the top wall. The top wall is adapted for movement within the box housing between a retracted position and an expanded position and to be raised by air pressure. Latches are provided to secure the vessel top wall in the expanded position to the box housing side walls, whereby the vessel can be filled with liquids. When in the retracted position, the top wall is close to the bottom wall with spacers on the bottom wall to support the top wall in the retracted position and to thus define a dead space to receive the retracted sleeve.

Abstract: The present invention relates to an apparatus for filtering solid matter from a gas. It particularly relates to improvements in bag house type filters for use in cleaning gas streams. There is provided a gas filter apparatus consisting of, in combination, a chamber having a top, base, and side walls, a conveyor tube for passing the solid laden gas into the chamber and centrally of a partition wall dividing the chamber into upper and lower compartments, gas and solid matter exit ports on the conveyor tube, in the lower compartment only, for use in distributing the gas and solid matter from the conveyor tube and directing at least a portion of the solid matter toward the base by gravity. The partition includes a number of openings communicating the upper and lower compartments, and filter tubes are provided in the lower compartment covering the openings.
