20120328467 | METHOD FOR THE PRODUCTION OF MIXED OXIDES AND PERMANENT MAGNETIC PARTICLES - Method for the production of mixed oxides and permanent magnetic particles, based on rare earths-transition metals to produce RETM magnetic materials, comprising the preparation of a parent compounds mixture; introducing the parent compound mixture into a reactor with heat energy input, where the atomization die generates fine droplets as spray or aerosol; subjecting the fine droplets formed to pyrolysis and combustion, and; reducing the mixed oxide particles formed and collected as homogenous powder, obtaining permanent magnetic particles; being a simple method and allowing to obtain homogeneous and versatile compositions, especially for Rare Earth-Transition Metal (RETM) type permanent magnets, where RE (rare earth) can be, for example, an element such as neodymium, praseodymium, dysprosium or a combination thereof, among other possibilities, and TM (transition metal) can be, for example, iron, cobalt, nickel or a combination thereof. | 12-27-2012 |

20120125314 | COVER PLATE FOR A DOMESTIC APPLIANCE, SAID COVER PLATE COMPRISING A FABRY-PEROT INTERFERENCE LAYER - A cover plate for a domestic appliance includes a support plate made of a glass or glass ceramics and having at least one at least partially transparent area for covering a display element. A coating is applied onto the support plate and includes at least one semi-transparent metallic layer having a layer thickness between 10 nm and 50 nm, at least one further metallic layer, and a dielectric separation layer separating the further metallic layer from the semi-transparent metallic layer. | 05-24-2012 |

20110116931 | METHOD FOR INCREASING THE COEFFICIENT OF ADHESION BETWEEN TWO PARTS ROTATING AS ONE WITH A ROTOR - A method for increasing the coefficient of adhesion between two parts that rotate as one with a rotor, for example a turbomachine rotor, those parts pressing against one another via pressing faces. The method includes milling at least one of the pressing faces so as to modify its surface finish and increase its roughness, then covering the or each machined face with a thin layer of a material that is hard and has a high coefficient of friction. | 05-19-2011 |
20110129310 | ANGLE-ROUNDING METHOD AND TOOL - A method of angle rounding at an intersection between two surfaces of a workpiece, the method including machining away a minimum volume of material from the intersection of the two surfaces, thereby giving a convex rounded shape to the intersection of the two surfaces, the curved shape being located relative to the workpiece on the outside of a circular arc tangential to the two surfaces at the point where the curved shape connects with the two surfaces. | 06-02-2011 |
