摘要： A method for solution mining nahcolite, capable of extracting nahcolite from geological formations lean in nahcolite comprising injecting high pressure water (which may include recycled aqueous solution of bicarb and sodium carbonate) at a temperature of at least 250° F. into the formation, dissolving nahcolite in the hot water to form a production solution and recovering the production solution. The invention also includes the processing of the production solution to provide sodium carbonate and, optionally, sodium bicarbonate, comprising: decomposing the sodium bicarbonate portion of the hot aqueous production solution to form a hot aqueous solution of sodium carbonate; evaporating water from the hot aqueous solution comprising sodium carbonate to form a concentrated solution of sodium carbonate; producing sodium carbonate monohydrate from the concentrated solution of sodium carbonate by crystallization; and dewatering and calcining the sodium carbonate monohydrate to produce anhydrous sodium carbonate.

摘要： A security device for a utility shutoff valve and a tool for inserting and removing the security device. The security device and tool are utilized for water and gas shutoff valves located underground that are accessed through a vertical access pipe. The invention is a cylindrical plug which is placed inside the access pipe, resting on top of the valve. The plug includes a grip resistant dummy valve handle which, when turned, causes the plug to rotate without having any effect on the valve. The plug is also very difficult to remove without the insertion/removal tool, comprising an inverted cup with a long handle, wherein the inside of the cup is lined with horizontal steel bristles. When the cup is placed over the top of the plug, the bristles enter corresponding holes in the dummy valve handle, allowing the plug to be lifted.
