Patent number: 8795794Abstract: The present invention concerns the down hole motors used in the oil prospecting industry to drive drill bits for drilling the ground at great depths. The down hole motor (1) comprises a drive shaft (5) held in the motor body (3) by an axial thrust bearing (6) and by a radial bearing (7). The radial bearing (7) is a tubular member whose interior surface is coated with an anti-abrasion layer (11) formed by laser-assisted facing directly inside an alloy steel radial bearing body (10). The thickness of the facing layer is then reduced by removing material by means of a cutting tool. This produces a radial bearing (7) that is relatively insensitive to drilling mud and confers great reliability on the down hole motor (1).Type: GrantFiled: February 8, 2008Date of Patent: August 5, 2014Assignee: TechnogeniaInventors: Didier Dezert, Guy Maybon

Patent number: 8784943Abstract: A dry refractory mix and a method for apply the dry refractory mix to a surface. One aspect of the invention utilizes gunning mixes without cement. The dry refractory mix also may include a setting agent that is homogeneously blended with the refractory mix. In operation, when used with pneumatic systems, dry refractory material is fed into a hopper of a gunnite machine, introduced into an air flow, and conveyed by air through one or more hoses to a nozzle. A liquid binder is introduced into the air flow for mixing with the suspended dry refractory material at or before the nozzle. A fitting, such as a water ring with holes, may be used for injecting the binder into the air flow containing the dry refractory material. The mixed refractory/binder material is discharged through the nozzle for application to a surface.Type: GrantFiled: March 11, 2010Date of Patent: July 22, 2014Assignee: Reno Refractories, Inc.Inventors: James Benson, Robert Pattillo, Heidi Zinn

Patent number: 8747959Abstract: Certain examples relate to improved methods for making patterned substantially transparent contact films, and contact films made by such methods. In certain cases, the contact films may be patterned and substantially planar. Thus, the contact films may be patterned without intentionally removing any material from the layers and/or film, such as may be required by photolithography. In certain example embodiments, an oxygen exchanging system comprising at least two layers may be deposited on a substrate, and the layers may be selectively exposed to heat and/or energy to facilitate the transfer of oxygen ions or atoms from the layer with a higher enthalpy of formation to a layer with a lower enthalpy of formation. In certain cases, the oxygen transfer may permit the conductivity of selective portions of the film to be changed. This advantageously may result in a planar contact film that is patterned with respect to conductivity and/or resistivity.Type: GrantFiled: June 30, 2011Date of Patent: June 10, 2014Assignee: Guardian Industries Corp.Inventors: Alexey Krasnov, Muhammad Imran, Willem den Boer

Patent number: 8734898Abstract: A method is provided that produces nanocomposite materials containing well-dispersed, nanoparticles encapsulated in a polymer matrix. A feedstock comprising a colloidal dispersion of nanoparticles in a solvent and a polymer dissolved in the same solvent is passed through an ultrasonic nozzle using a flow control device, producing an aerosol of drops having diameters less than about 100 micrometers. The aerosol of drops is then mixed with a fluid that is miscible with the solvent, is a nonsolvent for the polymer, and destabilizes the colloidal dispersion. As a result, well-dispersed polymer-encapsulated nanoparticles precipitate. The method operates at atmospheric temperature and pressure and allows for independent control of the precipitation of the particle and of the polymer.Type: GrantFiled: September 21, 2012Date of Patent: May 27, 2014Assignee: E I du Pont de Nemours and CompanyInventor: Jeffrey Scott Meth
