  • Patent number: 8795794
    Abstract: 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).

  • Patent number: 8784943
    Abstract: 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.

  • Patent number: 8771794
    Abstract: A method for treating flooring not designed for sanding and having a multi-layer wax finish reduces the frequency of stripping the wax layers down to the flooring and recoating the flooring in carrying out periodic maintenance on the flooring. A mobile floor treating machine includes at least one rotating brush which is driven at a first circular speed x for cleaning the flooring and is driven at a second circular speed y for removing the two uppermost layers of wax, where y?2x. The top remaining wax layer is then cleaned with the brush operating at the original circular speed x. Two layers of wax are then sequentially applied to the top remaining wax layer in replacing the two removed layers of wax on the floor and restoring the flooring to its original finish. The brush may be operated at 800-1500 RPM for burnishing and polishing.

  • Patent number: 8758854
    Abstract: To obtain a sugar-plum shaped composite particle, a reaction vessel with 300 parts by weight of water placed therein is charged with 30 parts by weight of polymethyl methacraylate resin particles of 2 ?m average particle diameter, and ultrasonic waves are applied to the mixture for 1 minute to obtain a particle dispersion liquid. Subsequently, 15 parts by weight of methyltrimethoxysilane is added to the dispersion liquid to obtain methyltrimethoxysilane hydrolyzates in the dispersion liquid. Thereafter, 10 parts by weight of 1 weight % aqueous ammonia is added thereto and agitated. One minute later, the agitation is discontinued, and the mixture is allowed to stand still for 10 hours to effect maturation. The resultant mixture is filtered and dried to obtain sugar-plum-shaped particles provided on their surfaces with polyorganosiloxane projections.

  • Patent number: 8747959
    Abstract: 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.

  • Patent number: 8734898
    Abstract: 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.

  • Patent number: 8722143
    Abstract: The present invention refers to a method for preparing a superhydrophobic surface on a solid substrate comprising the steps of (a) providing a solvent in the form of a pressurized fluid in a vessel, wherein the fluid exhibits a decrease in solvency power with decreasing pressure; (b) adding a hydrophobic substance to the solvent as a solute, which substance is soluble with the pressurized fluid and has the ability to crystallize/precipitate after expansion of the fluid, thereby obtaining a solution of the solvent and the solute in the vessel; (c) having at least one orifice opened on the vessel, thereby causing the pressurized solution to flow out of the vessel and depressurize in ambient air or in an expansion chamber having a lower pressure than within the vessel, the solute thereby forming particles; and (d) depositing the particles on the substrate in order to obtain a superhydrophobic surface.
