| 20110240244 | EXOTHERMIC WELDING MOLD WITH INTEGRAL COVER - An exothermal weld mold includes a mold section with an integral cover portion, made as part of a single piece of material with the rest of the mold section. The mold section may be a mold half of a vertically split mold, or may constitute most of a half of the mold. The cover portion may be part of an integral cover that covers substantially all of a reaction chamber or crucible of the mold. The cover may have one or more vent holes, in the top and/or side of the mold. The cover may have a baffled passage for expansion of gases produced by reaction of the weld material, before the gases are expelled from the mold at an opening in the top or side of the mold. The passage may be a serpentine passage. A filter may be placed in the passage. | 10-06-2011 |

| 20130299116 | METHOD AND APPARATUS FOR INTERLOCKING LOAD CARRYING ELEMENTS - A method for interlocking structural steel components with a metal-filled interlock is disclosed herein. The method comprises placing a mold about aligned contoured portions of structural steel components and attaching a crucible and a spout to the mold. The crucible is charged with exothermic reactive metals which are ignited, forming a molten metal filler. The molten metal filler melts a metal plug in the crucible or spout and the molten metal filler flows into the mold and about the aligned contoured portions of the structural steel components. Cooling of the molten metal filler forms a metal-filled interlock. Molds for performing the disclosed method are also disclosed herein. | 11-14-2013 |
| 20140182803 | METHOD AND DEVICE FOR THE ALUMINOTHERMIC WELDING OF RAILS - The invention concerns a method for the aluminothermic welding of rails, comprising the steps of:
| 07-03-2014 |
| 20150328716 | Device and process for remote ignition in aluminothermic welding - It enables to use very limited energy and an easily transportable device. Comprises: a) a consumable ignition element with a resistive wire to be heated as the electric current passes through it and cause a remote ignition; b) a reusable intermediate element, provided with fitting means to be electrically connected with the ignition element; c) a portable case to house a portable power source and, d) an ignition switch that is housed in the case, with a push button to activate the power source, as well as a first indicator adapted to turn on if the power source is available and a second indicator adapted to turn on if the contact between the first tracks and the second tracks is correct. | 11-19-2015 |
