Publication number: 20140126965Abstract: The process “Washing contaminated soils” solves the problem of cleansing and remediating soils and sediments and their fine fractions contaminated with toxic metals, using washing solution with chelating agents. The chelating agent forms water-soluble complexes with metals and thus facilitates metal removal from soils and sediments into the washing solution. In addition to toxic metals, the process according to the invention enables removal of organic pollutants from soils and sediments by using washing solution amended with surfactants, detergents or organic solvents in addition to chelating agents. The process according to the invention provides for simultaneous separation of the soil and sediment solid phase and used washing solution in a chamber filter press, and effective rinsing of the solid phase to remove all residual mobilized contaminants.Type: ApplicationFiled: June 15, 2012Publication date: May 8, 2014Applicant: ENVIT, Environmental Technologies and Engineering Ltd.Inventor: Domen Lestan

Publication number: 20140127011Abstract: A mounting apparatus includes a bracket, two shafts, and a number of shield plates. The bracket includes a fixing plate defining a number of horizontally arranged vents, for mounting a number of fans to a rear side of the fixing plate, with each vent aligning with one of the fans. The shafts are respectively and horizontally mounted to a top and a middle of a front side of the bracket. Each shield plate includes a main plate and a substantially C-shaped pivot portion formed on a top of the main plate. The pivot portions of the shield plates are rotatably placed around the shafts. The shield plates hang vertically under the corresponding shafts by gravity. Each of the vents is covered by two vertically aligned shield plates upon a condition that the gravity of the two shield plates is not overcome by airflow through the vents.Type: ApplicationFiled: December 26, 2012Publication date: May 8, 2014Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: ZHENG-HENG SUN
