Abstract: A process for removing water from solid material using liquid-solid extraction and liquid-liquid extraction. In most embodiments, multiple solvents are used to remove the water from the solids and obtain dry solids. Multiple solvents facilitate the removal of the water from the solids, by replacing the water with a solvent, replacing that solvent with a different solvent, and then eventually removing the second solvent from the solids. The process utilizes a lesser amount of thermal energy to dry the solids and separate the solvents than conventionally used in drying processes. The first solvent selected has a lower heat of vaporization, enthalphy of vaporization, boiling point, or other such physical property, than water. Each additional solvent can have a still lower heat of vaporization, enthalphy of vaporization, boiling point, or other such physical property.

Abstract: A process for removing water from solid material (10) using liquid-solid extraction and liquid-liquid extraction in an extraction system (100). Multiple solvents are used sequentially to replace the water with a first solvent, then replacing that solvent with a second solvent, etc., then eventually removing the last solvent from the solid materials. The solvents have progressively lower heats of vaporization, enthalphy of vaporization, boiling point or related property, so as to conserve use of thermal energy.

Abstract: An athletic sideline seating device having storage capability and removable and replaceable signage is disclosed. A seating apparatus defining a storage area is provided, on which one or more sign elements can be coupled. The storage area may be accessed in a number of ways, for example, by hinged seat or front panel, or by an access door in one or more sides. The device is portable and may include handles, moving elements and lightweight materials for that purpose. Additionally, the invention may include a trainer's table and/or an equipment table that are storable within the seating apparatus and easily coupled to the outside of the seating apparatus.

Abstract: A process for removing residual amounts of a first solvent from a granular material. The process includes the selection of a second solvent which has an ambient pressure boiling point lower than that of the first solvent in mixing the second solvent with the granular material and first solvent. Most of the liquid solvent mixture is removed from the granular material using a simple solid/liquid extraction process. The remaining solvent mixture, which primarily is the second solvent, is removed from the granular material using a thermal and/or vacuum process.
