(Targeted News Service Via Acquire Media NewsEdge) Targeted News Service Targeted News Service ALEXANDRIA, Va., Feb. 16 -- The following federal patents were awarded to inventors in South Carolina.

*** General Electric Assigned Patent ALEXANDRIA, Va., Feb. 16 -- General Electric, Schenectady, N.Y., has been assigned a patent (8,373,089) developed by four co-inventors for a "combustion cap effusion plate laser weld repair." The co-inventors are Jere A. Johnson, Greenville, S.C., Srikanth Chandrudu Kottilingam, Simpsonville, S.C., Gene Arthur Murphy Jr., Pelzer, S.C., and Liangde Xie, Simpsonville, S.C.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A process for modifying or repairing a metallic component, such as a combustion cap effusion plate for a gas turbine, is disclosed. The method includes generating a notch or groove in the metallic component and depositing a filler material in the notch or groove. A pulsed laser is applied to the filler material. The pulsed laser has a power, frequency, and pulse width sufficient to apply heat to the metallic component and to the filler material to make at least a portion of the metallic component and the filler material melt in order to weld the filler material to the metallic component and repair or modify the metallic component. Various operating parameters of the pulsed laser can be configured to reduce undesirable heating affects." The patent application was filed on Aug. 31, 2009 (12/550,740).

*** University of South Carolina Assigned Patent ALEXANDRIA, Va., Feb. 16 -- The University of South Carolina, Columbia, S.C., has been assigned a patent (8,372,344) developed by Thomas M. Crawford, Irmo, S.C., and Samir Y. Garzon, Cayce, S.C., for a "nanoscale spintronic chemical sensor." The abstract of the patent published by the U.S. Patent and Trademark Office states: "In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface." The patent application was filed on Oct. 11, 2007 (12/442,951).

*** University of South Carolina Assigned Patent ALEXANDRIA, Va., Feb. 16 -- The University of South Carolina, Columbia, S.C., has been assigned a patent (8,372,697) developed by Asif Khan, Irmo, S.C., and Vinod Adivarahan, Columbia, S.C., for a "digital oxide deposition of SiO.sub.2 layers on wafers." The abstract of the patent published by the U.S. Patent and Trademark Office states: "Novel silicon dioxide and silicon nitride deposition methods are generally disclosed. In one embodiment, the method includes depositing silicon on the surface of a substrate having a temperature of between about 65.degree. C. and about 350.degree. C. The heated substrate is exposed to a silicon source that is substantially free from an oxidizing agent. The silicon on the surface is then oxidized with an oxygen source that is substantially free from a silicon source. As a result of oxidizing the silicon, a silicon oxide layer forms on the surface of the substrate. Alternatively, or in additionally, a nitrogen source can be provided to produce silicon nitride on the surface of the substrate." The patent application was filed on May 7, 2007 (11/800,712).

The abstract of the patent published by the U.S. Patent and Trademark Office states: "An apparatus and method for cooking food, such as meat, protein, vegetable, or soup is disclosed. In one embodiment, the food items are supplied in a flexible polymer package that can withstand the temperature needed to cook the item. The cooking apparatus has two cooking surfaces in the form of heated platens, which may be arranged in a vertical orientation. These platens come together to simultaneously contact both sides of the food item. The cooking apparatus further includes a controller, configured to prepare the food using various control system algorithms. The apparatus cooks the food item from both sides to affect rapid and even cooking. It uses a combination of temperature, time, food thickness, platen force and a cooking code that is unique for each food type. The control system algorithm uses some or all of these parameters to determine precisely when the food item is cooked correctly." The patent application was filed on June 15, 2010 (12/816,022).
