  • Patent number: 9580337
    Abstract: A pressurized forward osmotic separation process is disclosed. Generally there are two processes described. One process involves the concentration of a target solute in the first solution; the other process involves the extraction of a solvent from a first solution both by a second solution comprising of water and soluble gas or water, soluble gas, and a compound by creating an osmotic concentration gradient across the semi permeable membrane. The first solution is under pressure from an inert gas and the second solution is under pressure from a soluble gas with equal system pressures greater than 1 atmosphere. The increase or decrease of partial pressure of the soluble gas in the second solution increases or decreases the chemical potential of the second solution to achieve different solution properties. The soluble gas may be carbon dioxide and the compound may be magnesium hydroxide.

  • Patent number: 5280986
    Abstract: A tailgate for a utility hauling vehicle is alternatively held in either a closed position or a supported position by a pair of formed rods which are located at the opposite ends of the tailgate. When the rods are in latched positions, they are slightly flexed so as to create a bias which acts between the rods and the tailgate to maintain a rattle-free connection.
