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 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: 8030592Abstract: A plasma spray apparatus in the form of a gun is utilized to apply an antifoulant coating to marine vessels. The apparatus includes a plasma generator, an electrophoresis element, a heating element, a shield gas element, a liquid cooling system, a forced air system, and a vacuum system. The plasma generator ionizes gas to create a plasma stream, which is utilized in part to supply energy to the heating element that heats a powder material. The heated powder material is exposed to the electrophoresis element to create a covalently bonded coating material. The coating material is injected into the plasma stream and is applied to a target surface. The shield gas element injects a gas flow to surround and protect the plasma and coating material stream as the stream is in flight to the target surface. The liquid cooling system cools portions of the plasma generator and heating element. The forced air system cools a portion of the target surface as the coating material is being applied.Type: GrantFiled: June 6, 2007Date of Patent: October 4, 2011Assignee: Reintjes Marine Surface Technologies, LLCInventor: Larry Weidman

Patent number: 8021710Abstract: The present invention relates to methods and apparatus for producing an electronic device, such as an organic light-emitting diode (OLED), having an electrode with enhanced injection properties. An example method according to the invention comprises the steps of providing an electrode, depositing a first layer of molecular charge transfer material on the electrode, and cross-linking the molecular charge transfer material. With the method according to the invention, an OLED with higher light efficiency, lower operating voltage, and longer lifetime can be produced. The present invention further relates to an electronic device having an electrode with enhanced injection properties.Type: GrantFiled: August 16, 2005Date of Patent: September 20, 2011Assignee: International Business Machines CorporationInventors: Thomas Brunschwiler, Siegfried F. Karg, Walter Riess

Publication number: 20110217477Abstract: A process for coating a substrate comprising condensing a radiation curable material on a substrate and curing it using an electron flux 6? with energy between 6.5 eV and 300 eV. The electron flux 6? is directed at the substrate (2) either simultaneously or sequentially with delivery of the curable material (5?). Curing is preferably initiated spatially and temporally concurrently with delivery of the material to the substrate. The electron flux is preferably generated using a low pressure gas plasma source with a driving voltage negative relative to the local voltage conditions. The low pressure gas plasma (6?) is preferably magnetically enhanced and, for example, incorporates a magnetron.Type: ApplicationFiled: September 24, 2009Publication date: September 8, 2011Applicant: CAMVAC LimitedInventors: John Topping, David Anthony
