Patent number: 8252387Abstract: An isothermal, low pressure-based process of depositing material within a substrate has been developed, and is particularly useful in forming an optical fiber preform results in creating an extremely narrow reaction zone within which a more uniform and efficient deposition will occur. Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The exhaust end of the tube is connected to a vacuum system which is in turn connected to a scrubber apparatus for removal and neutralization of reaction by-products. The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.Type: GrantFiled: December 10, 2007Date of Patent: August 28, 2012Assignee: OFS Fitel, LLCInventors: James W.

Patent number: 8110043Abstract: A methodology and system for applying coatings onto the interior surfaces of components, includes a vapor creation device, a vacuum chamber having a moderate gas pressure and an inert gas jet having controlled velocity and flow fields. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved. The carrier gas flow and chamber pumping rate control the downstream pressure. The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. These collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit.Type: GrantFiled: January 10, 2005Date of Patent: February 7, 2012Assignee: University of Virginia Patent FoundationInventors: Derek D.

Patent number: 7810523Abstract: A method is provided for reducing seepage through a leak (5) in a duct (1), the leak being defined in terms of its maximum dimension xL and its maximum width in an orthogonal direction yL and the effective size of the leak being given by formula (1): SL=(x2L+y2L)1/2. A plurality of sealing elements (3) are introduced into the duct, the sealing elements having dimensions a, b and c in mutually orthogonal directions and the effective size SE of the sealing element being given by formula (2): SE=(a2+b2+c2)1/2. The sealing elements have an effective size SE, which is less than the effective size of the leak SL, so that sealing elements (3A) are drawn to the leak locality and caused, by reason of a pressure differential at that locality and attributable to the leak, to move over the leak and reduce the seepage.Type: GrantFiled: April 29, 2003Date of Patent: October 12, 2010Assignee: Brinker Technology LimitedInventors: Ian Kenneth McEwan, Ian Beveridge Chirnside, Nicholas John Ryan

Patent number: 7608298Abstract: A method of manufacturing a ceramic porous membrane on inner wall surfaces of through holes of a porous base member. The through holes of the base member are arranged in a vertical direction, a ceramic sol liquid having a temperature difference of 50° C. or less between the sol liquid and the base member is supplied to the inner wall surface of the base member, the liquid supply is stopped when the sol liquid exceeds an upper end portion of the base member, and then the sol liquid is extracted from the bottom of the base member. After the sol liquid is completely extracted, a pressure difference is created so that a pressure on the side of an outer peripheral surface of the base member is lower than that on the side of the inner wall surface of the base member.Type: GrantFiled: September 21, 2007Date of Patent: October 27, 2009Assignee: NGK Insulators, Ltd.Inventor: Kei Tanaka
