| 20110146846 | METHOD FOR CUTTING WITH GAS AND APPARATUS FOR CUTTING WITH GAS - The object of the present invention is to provide a method for cutting with gas which uses a cutting tip including a preheating hole for forming a preheating flame with a fuel gas and an oxygen gas for preheating, and an oxygen gas hole for cutting a workpiece by injecting oxygen gas for cutting, and which can decrease an amount of hydrogen gas used by supply a fuel gas to the preheating hole, which is appropriate in both heating and cutting the workpiece, and an apparatus for cutting with gas, and the present invention provides an apparatus for cutting with gas ( | 06-23-2011 |
| 20130032250 | GAS CUTTING METHOD, GAS CUTTING MACHINE, AND CUTTING TIP - A gas cutting method is provided which includes: mixing hydrogen gas and hydrocarbon gas to acquire fuel gas; ejecting a preheating flame, which is formed by mixing and igniting the fuel gas and preheating oxygen gas, from an end of a cutting tip to heat a workpiece; and ejecting cutting hydrogen gas to the heated workpiece to cut the workpiece. Here, the content of the hydrocarbon gas in the fuel gas is more than 0 vol % and equal to or less than 4 vol %. | 02-07-2013 |
| 20130112320 | METHODS OF SEVERING AN OBJECT FROM THE OUTSIDE USING HEAT EVOLVED FROM AN EXOTHERMIC REACTION - According to an embodiment, a method of severing at least a first object comprises: positioning a severing device adjacent to the first object, wherein the first object is a wireline or a tubular, and wherein the severing device comprises: a first reactant, and a second reactant; initiating a reaction, or allowing a reaction to occur, between the first reactant and the second reactant, wherein the reaction is an exothermic reaction, and wherein heat evolved from the reaction has a temperature greater than or equal to the melting point of the first object; and directing at least a portion of the heat from the outside of the first object through the first object. | 05-09-2013 |
| 20130220487 | SILENT ENTRY TORCHING AND OXYGEN DELIVERY SYSTEM AND CONFIGURATION - A system for performing exothermic operations or oxygen delivery uses a rod and handle configuration to create a flowpath of oxygen. The rod includes cables having stainless steel fibers that burn using the oxygen within a hollow center area. While burning, the rod cuts through material. A sheath covers the covers to contain the gases and prevent unraveling of the cables. The handle attaches to the rod and provides control of the flow of oxygen to the rod. A manifold fixing in place bottles of oxygen connects to the handle and can be fixed to provide different mixtures from different bottles. The rod is disconnected when needed to fix a mask thereto for delivering breathable oxygen to a patient. | 08-29-2013 |
| 20130340893 | COMBUSTIBLE GAS - Combustible gas, which is easy to be stored, transported and the like and can contribute to improving the quality of a finished state of an operation such as gas cutting, gas welding or brazing, contains ethylene at 38 v/v % or more and 45 v/v % or less and the remainder being hydrogen and unavoidable impurity. | 12-26-2013 |

| 20110265914 | Tankless Exothermic Torch - A thermite torch is disclosed that contains a thermite composition made of a bimodal mixture of nano-sized particles and micro-sized particles. Also disclosed is a tankless exothermic torch comprising a rod and a handle that contains a gas generating compound in the handle. The thermite torch gun does not require a tank of compressed gas. Elimination of this tank mitigates dangers and logistical burdens associated with it presence and use, without compromising operation or cutting performance. The rod may contain a high-density mixture of oxygen-releasing and/or heat-releasing chemicals. Preferably, the mixture comprises a bimodal-blend of nanometer and micrometer-sized particles in a closely-packed configuration to fill interstitial voids. The gun may contain an ignition module and power supply for initiating directed high-temperature flame jetting, and for turning it on/off/on when a solid-chemical oxygen generator is mounted in the gun. | 11-03-2011 |

| 20090277538 | FRAMED TEM MACHINE AND METHOD OF OPERATING SAME - A thermal energy method (TEM) machine for deburring and deflashing work pieces, the TEM machine having an explosion load bearing frame. The frame comprises spaced apart coparallel first and second frame walls and a lateral structural member spacing apart the first and second frame walls. The top portion of the TEM combustion chamber is supported by the lateral structural member. The first and second frame walls are adapted to support a vertical displacement means. The first and second frame walls, the lateral structural member, and the vertical displacement means cooperate to contain vertically-directed explosion forces exerted upon the combustion chamber during the operation of the combustion chamber. Methods for deburring and/or deflashing using such TEM machines are also disclosed. | 11-12-2009 |
