WO/2015/025193 TIDAL ENERGY SEAWATER DESALINATION SYSTEM||WO||26.02.2015|
||PCT/IB2013/056767||SANFT, William||SANFT, William|
A submerged Bladder with a floor level fixed to a height the same as or just below the lowest low tide level has flexible side-walls and a ceiling which is fixed to a floating Buoy. The Bladder flexible walls have a height that is slightly over the length of the lowest low tide level and the highest high tide level. Seawater desalination membranes are fixed under the floor or integrated into the floor. As the tide rises, the Buoy rises with it. The rising Buoy causes the Bladder to open up. As the Bladder opens up, seawater is pulled into the Bladder to fill the new space available inside the Bladder. The seawater is desalinated as it travels through the membranes, and enters the Bladder as desalinated potable water. At peak high tide mark, the Bladder outlet pipe is opened to drain the contents of the Bladder to an on-shore Reservoir. During the draining process, an air-lock valve on top of the Bladder is opened to aid drainage of water. This operation takes place twice a day consistent with tidal flow, every day, for any volume of water, with no cost for external power source.
WO/2015/025624 EXHAUST PURIFICATION SYSTEM OF INTERNAL COMBUSTION ENGINE||WO||26.02.2015|
||PCT/JP2014/067849||TOYOTA JIDOSHA KABUSHIKI KAISHA||HABA, Yuki|
In an internal combustion engine, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged in an engine exhaust passage. A first NOX removal method which injects hydrocarbons from the hydrocarbon feed valve (15) within a predetermined range of period so that the reducing intermediate generated thereby reduces the NOX contained in the exhaust gas and a second NOX removal method which makes the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) a first target rich air-fuel ratio by a period which is longer than this predetermined range are used. When the NOX removal method is switched from the second NOX removal method to the first NOX removal method, the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) is made a second target air-fuel ratio which is smaller than the first target rich air-fuel ratio.

The invention relates to a process for the removal of contaminants from a liquor, the process comprising: introducing a metal or ammonium hydroxide into the liquor; introducing the liquor into a reaction vessel; bubbling a carbon dioxide
gas comprising at least 25% carbon dioxide
through the liquor within the reaction vessel; and separating the precipitate formed by the carbonatation of the metal hydroxide from the liquor, the precipitate comprising at least some of the contaminants from the liquor; wherein, on average, the liquor is resident within the reaction vessel for a period of no more than about 60 minutes and wherein the size of the precipitate may be at least partially controlled or controllable by altering the residence time of the liquor in the reaction vessel or the p H of the liquor in the reaction vessel. The invention also relates to a process for the removal of contaminants from a liquor, the process comprising: introducing a metal or ammonium hydroxide into the liquor and bubbling a carbon dioxide
gas comprising at least 25% carbon dioxide
through the liquor to form a precipitate by carbonatation in a period of no more than about 60 minutes and wherein the size of the precipitate may be at least partially controlled or controllable by altering the residence time of the liquor in the reaction vessel or the p H of the liquor in the reaction vessel. The carbonatation processes may be included in sugar refining or water softening and/or decontamination processes. A use of a carbon dioxide
gas comprising at least 25% carbon dioxide
in a carbonatation process for removing contaminants from a hydroxide-treated liquor is also provided, wherein the process forms a precipitate in a period of no more than about 60 minutes and wherein the size of the precipitate may be at least partially controlled or controllable by altering the residence time of the liquor in the reaction vessel or the p H of the liquor in the reaction vessel.
