Abstract: A bag device for storing a body includes upper and lower impervious flexible panel members each having opposed side edges and opposed ends. Respectively side edges of the members are formed integrally therealong, and the members are movable to form a cavity for storing the body. The end is closed and the end is normally open so that can be inserted into the cavity. The members are laminates of thermoplastic sheets and the open end can be sealed by application of heat to the thermoplastic sheets at the open end. Pressure release valves are fixed to the member so that excess pressure in the cavity due to body decomposition is released to the atmosphere.

Abstract: Wetting device for wetting and dissolving polymer powders without forming lumps and globular "fish-eyes" which clog the system apparatus. A nozzle holder has an annular passageway disposed therein which communicates with each of a plurality of spaced jet spray nozzles secured to the holder on a bottom face thereof in the form of a ring. Alternate nozzles spray inwardly forming a turbulent curtain of water. Remaining nozzles spray outwardly against inner wall of a spray confining cylinder to wash down polymer therefrom. An open-ended, powder receiving, tubular flexible insert extends through a central opening of the nozzle holder creating an annular space around the flexible insert. Water supplied to the passageway sprays from the nozzles to induce a downward airstream in the annular space to aid in drawing powder through the insert while simultaneously maintaining the powder in a finely divided state when falling into the turbulent curtain of water.

Abstract: Powdered polyelectrolytes are wetted and mixed with water in a cone-shaped member to form solutions which are useful, for example, in promoting floc formation for removal of suspended particulate matter. Improperly wetted and/or mixed powders tend to form lumps to periodically clog the throat of an eductor conventionally employed in the formation of such solutions. The present invention employs an orificed disc to form multiple jets of high velocity water to impact any lumps exiting from the lower portion of the cone-shaped member for break-up of said lumps to thereby provide a lump-free solution which does not clog the throat of an eductor disposed downstream of the orificed disc, the eductor educing the lump-free solution into an aging and/or storage tank.
