Patent number: 9803139Abstract: A method for selectively removing an aluminum-silicon coating fired on a surface of a metallic structure is described. The method includes the step of contacting the coating with molten potassium hydroxide (KOH), under conditions sufficient to remove the coating without substantially affecting the metallic surface. Methods for preparing a magnetic component are also described. They involve masking pre-selected regions of the surface of the component, using an aluminum-silicon coating that is fired onto the surface, prior to a nitriding step. The coating is then removed according to the procedure outlined herein.Type: GrantFiled: June 24, 2016Date of Patent: October 31, 2017Assignee: General Electric CompanyInventors: Peter John Bonitatibus, Jr., Francis Johnson, Min Zou

Patent number: 9368840Abstract: A method of maintaining the performance level of an electrochemical cell is described. The cell usually includes a negative electrode that includes an alkali metal; a positive electrode that includes at least one transition metal halide; a molten salt electrolyte based on an alkali metal haloaluminate; and a sodium ion-conducting solid electrolyte partitioning the positive electrode from the negative electrode. The method is based on a treatment regimen that includes the step of applying a series of electrical cycles to the cell, wherein the series includes at least one deep discharge of the cell. Each discharge of the cell is usually followed by recharging the cell to its available capacity.Type: GrantFiled: November 30, 2012Date of Patent: June 14, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Rebecca Suzanne Northey, Peter John Bonitatibus, Jr., John Thomas Leman, Job Thomas Rijssenbeek

Patent number: 9251938Abstract: A method of synthesizing magnetic nanoparticles comprising soft magnetic phases is provided, wherein the method comprises degassing a first mixture at a temperature in a range from about 80° C. to 130° C. The first mixture comprises a solvent, a compound comprising iron, cobalt, or combinations thereof dissolved in the solvent, and an organic component comprising a fatty acid or an amine. Degassing the first mixture is followed by adding a capping ligand to the first mixture under inert atmosphere to form a second mixture; adding a reducing agent to the second mixture at a temperature in a processing temperature range from about 250° C. to about 350° C. to form a third mixture; and incubating the third mixture at a temperature within the processing temperature range to form nanoparticles comprising a soft magnetic phase.Type: GrantFiled: March 7, 2013Date of Patent: February 2, 2016Assignee: General Electric CompanyInventors: Binil Itty Ipe Kandapallil, Robert Edgar Colborn, Peter John Bonitatibus, Jr., Francis Johnson

Patent number: 9149545Abstract: The present invention is generally directed to core/shell nanoparticles, wherein such core/shell nanoparticles comprise a nanoparticle core and a nanoshell disposed about the nanoparticle core such that, in the aggregate, they form a core/shell nanoparticle that is operable for use as an imaging agent in X-ray/computed tomography (CT). Typically, such core/shell nanoparticle-based X-ray CT imaging agents further comprise a targeting species for targeting the imaging agent to diseased sites. Included herein are methods for forming such agents, comprising forming an ensemble of core/shell nanoparticles, wherein the mean diameter of the ensemble of core/shell nanoparticles is selected so as to render the nanoparticles in the ensemble substantially clearable by a mammalian kidney.Type: GrantFiled: November 24, 2008Date of Patent: October 6, 2015Assignee: General Electric CompanyInventors: Peter John Bonitatibus, Jr., David Cheney deMoulpied, Andrew Soliz Torres, Amit Mohan Kulkarni, Robert Edgar Colborn, Paul William Buckley
