Patents by Inventor Rafael Lanza Rivas

Rafael Lanza Rivas has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6949153
    Abstract: The manufacture is carried out in a continuous manner simultaneous to the filling of the shot holes, in a mixer, preferably a rotating mixer, wherein a water-based, non-explosive or low sensitivity matrix, an air bubble stabilizing agent, and optionally, an oxidant in granular form and a combustible material are mixed together. The nature of the water-based matrix, together with the use of an air bubble stabilizing agent, allows the incorporation of air during the mixing, regulating the density of the final product and acting on the variables of the process. On coming out of the mixer, the explosive is totally sensitized and has reached its final density, allowing for quality control before filling the shot hole. The process may be carried out on the explosives pumping truck, with compartments for the transportation of a water-based matrix, an oxidant in granular form, a combustible material and a gas bubble stabilizing agent.

  • Patent number: 6610158
    Abstract: The procedure involves the mixture of a water based oxidizing product with an oxygen balance greater than 14% consisting of a water solution saturated with oxidizing salts, oxidizing particles in suspension and thickening agents, with a fuel and a gas in a mixer, by means of the formation of an intimate mixture of the oxidizing product and the fuel and the formation of a suspension or emulsion of gas in the mixture. The density of the end explosive product may be varied according to the gas flow and this is controlled before introducing the explosive into the bore. The installation consists of a tank (1) with the oxidizing product, a fuel tank (11), a gas reserve (10), a mixer (5), a pump (3), a dosing device for the fuel (12) with a flow meter (13) and a regulating device of the gas flow (8), and, optionally, a tank (2) with a stabilizer of the gas bubbles, a dosing pump (4) and a flow meter (7).

  • Patent number: 6537399
    Abstract: The process for sensitizing in situ aqueous explosives before charging the mine holes comprises the formation of an emulsion of dispersion gas-in-liquid from a low sensitivity or non explosive matrix product which consists of a liquid mixture in solution, emulsion or suspension of oxidant in fuel, and a gas. The density of the final explosive product can be varied as a function of the gas flow rate and can be controlled before introducing it into the hole. The installation comprises a tank (1) with the matrix product, a gas reserve (10), a mixture (5), a pump (3), and a gas flow rate regulating device (8) and optionally a tank (2) with a gas bubble stabilizing agent, a dosing pump (4) and a flow meter (7).
