Patent number: 9556371Abstract: A method of forming a colloidal dispersion includes providing a first continuous material flow, providing a second continuous material flow, combining the first and second continuous material flows, and moving a continuous flow of a colloidal dispersion in a direction downstream of the first and second continuous flows. The first continuous material flow includes one or more of a diluent (e.g., deionized water), a base, and an acid, and the second continuous material flow includes an abrasive particle solution. The first and second material flows are combined with a Reynolds number greater than about 4400 and less than about 25000 (e.g., about 7400 to about 25000).

Patent number: 8974677Abstract: Fluid processing apparatuses and systems are disclosed. In some embodiments the fluid processing apparatuses include a movable enclosure, a plurality of filter housings disposed substantially within the movable enclosure, and a stand disposed within the enclosure. The filter housings are in fluid communication with one another. Each filter housing defines an elongate path and is configured to support a respective filter along the elongate flow path to filter a substantially continuous flow of fluid. The stand supports each filter housing such that the elongate flow path of each filter housing is substantially parallel to a vertical axis, wherein each filter housing is independently rotatable, relative to the stand.Type: GrantFiled: August 5, 2010Date of Patent: March 10, 2015Inventors: Saeed H. Mohseni, Deepak Mahulikar

Patent number: 8779011Abstract: A method for producing and using an ultrapure colloidal silica dispersion is disclosed. The ultrapure colloidal silica dispersion has less than 200 ppb of each trace metal impurity disposed therein, excluding potassium and sodium, and less than 2 ppm residual alcohol. The method comprises dissolving a fumed silica in an aqueous solvent comprising an alkali metal hydroxide to produce an alkaline silicate solution, removing the alkali metal via ion exchange to generate a silicic acid solution, adjusting temperature, concentration and pH of said silicic acid solution to values sufficient to initiate nucleation and particle growth, and cooling the silicic acid solution at a rate sufficient to produce the colloidal silica dispersion.Type: GrantFiled: February 24, 2012Date of Patent: July 15, 2014Assignee: Fujifilm Planar Solutions, LLCInventors: Deepak Mahulikar, Yuhu Wang, Ken A.
