Patent CA-2396081-A1 (CA)
Inventor: MURZYNOWSKI ALAN
IPC: G03G15/08
Filed: 2000-12-19
Abstract: A system and method for applying electrically charged non-magnetic toner to an image device, and subsequently to a moving substrate, provides precise level  control, proper control of the electrical charge of the toner, minimization of dusting problems, and maximum evenness of the toner layer. First and second fluidized toner beds have the toner in them charged using corona sources. Th e second bed maintains a level of toner above the level in the first bed, and a spillway-defining restraining dam is disposed between the beds so that the toner above the level desired in the second bed spills over the restraining dam into the first bed, allowing very precise control of the level of toner in the second bed. Toner transfer mechanisms (such as rotating conductive cylinders) transfer toner from the first bed to the second bed, and from the  second bed to the image device. Scrapers scrape excess toner from the rotati ng cylinders so that it falls back into either the first or second bed.

Title: In situ immobilization of metals within density variant bodies of water
Inventor: HARRINGTON JOSEPH G
IPC: B09C1/10
Filed: 2001-10-03
Abstract: A method for treating (in situ) large bodies of water con ta minated with heavy metals and having varying density stratas to immobilize the contaminant metals is disclosed. The method, or process for (in situ) immobilization of metals is focused on treating large bodies of water having metals therein that are also adjacent a border of soil or earthen materials in an attempt to immobilize the metals from penetrating through the soil. The method is also able to treat the soil water boundary within the pit lake to provide additional immobilization. The pit lakes can include open pit lakes, subterranean mine lakes, flowing streams and the like. The method is also able to treat an abandoned mine prior to the filling of the mine with water.  Initially, the density mean of the body of water is determined, which is densest typical at regions at or approaching 4 degrees C. The process includes introducing a treatment substance that has a density greater than that of the density means into the body of water, providing at least one microbe proximate or in the body of water, producing microbial sulfides arising from the initial microbe placement, causing microbial sulfides to react (in situ) with metal ions or m etal containing compounds located within the body of water, reducing the solubility of the metal ions by forming metal sulfides, and inhibiting the migration rate of the metal ions or other metal containing compounds within or from the soils or earthen materials as they settle out of the water.
