Publication number: 20100245453Abstract: A fluid reservoir for use in a printing device includes a housing that, at least partially, forms at least one chamber therein. The chamber is configured to hold a fluid. A bubble port leads through housing into a first region of chamber and fluidically couples chamber to atmospheric gas external to housing. A bubble director arranged within chamber is configured to direct at least one bubble of gas from first region to a second region of chamber. The bubble is formed within fluid within first region upon gas entering chamber through bubble port.Type: ApplicationFiled: June 11, 2010Publication date: September 30, 2010Inventors: Ralph L.

Publication number: 20030019764Abstract: An under the counter water treatment system. Water from an outside supply source, such as a municipal water line, is provided to user's home. A prefilter to remove sediment, organic compounds, and certain pollutants is first provided. After the prefilter, the water enters a reverse osmosis system which includes an osmotic membrane. The reverse osmosis membrane filters out impurities and very small particles to provide highly purified water. The outflow of the reverse osmosis filter is stored in a water tank. Water is removed from the tank by releasing an appropriate valve when the user wishes to drink the water. When the water exits the tank, it passes through a mineral supplement which adds minerals to the water beneficial to human or animal consumption. It then passes through an electrolytic cell having a plurality of plates.Type: ApplicationFiled: February 20, 2002Publication date: January 30, 2003Applicant: H20 Technologies, Ltd.Inventors: Kit G.
