| 20090159642 | Process of Brazing/Soldering By Flame of Metallic and Non-Metallic Materials - The invention refers to the flame soldering/brazing procedure of metallic and nonmetallic materials, used in industrial operations without releasing of noxious gases emissions. The soldering/brazing procedure according to the invention is achieved totally eliminating the noxious gases emissions, reducing the energy consumption for the soldering/brazing operation, and improving the quality of the joints by eliminating the influence of the temperature on the joint materials, in the following stages: cleaning and pickling of the joining surfaces with soldering/brazing flux, adapted as type and method to the specification of the materials that make up the joint; preparation and positioning of the joining components according to the joining drawing and ensuring a correct joint gap in relation to the added metal; uniform heating or the joint until the soldering/brazing alloy melted with the help of a burner with HHO oxy-hydrogen gas at a pressure of 0.1รท0.3 MPa; cooling of the joint with air and its protection so that it is not moved or stricken during the cooling and solidification of the soldering/brazing alloy. | 06-25-2009 |
| 20090199465 | PROCEDURE OF OBTAINING AUTOMOTIVE FUELS AND THE MODIFIED FUELS OBTAINED BY MEANS OF THIS PROCEDURE - The invention refers to a procedure of obtaining automotive modified fuels with the help of this procedure based on treating the fuels resulting from petroleum refining with the HHO mixture. In full compliance with this invention, the procedure comprises treating the fuel with a HHO gaseous mixture coming up as a result of the water electrolysis, in the presence or in the absence of catalytic agents, at temperatures between 20 and 100 Celsius degrees, at pressures between 1 and 20 atmospheres, and as long as 0.2 to 8 hours. | 08-13-2009 |
| 20100132661 | METHOD OF USING LEAN FUEL-AIR MIXTURES AT ALL OPERATING REGIMES OF A SPARK IGNITION ENGINE - The present invention refers to a method of using lean fuel-air mixtures at all operating regimes of a spark ignition engine, which is provided with an intake port fuel injection system, wherein said method is characterized in that in order to achieve the efficient lean mixture combustion process, an HHO oxy-hydric gas direct injection should be at a minimum pressure of 10 bar, during compression stroke, after intake valve closing, so that the hydrogen/fuel mixture volumetric fractions value is within the range of about 15% to 25%. | 06-03-2010 |
