Patent number: 11420295Abstract: An exothermic cutting rod comprising an ignition assembly portion and a main portion. The main portion may comprise a plurality of fuel rods and a rod housing that is configured to allow a flow of oxygen to the ignition assembly portion. The ignition assembly portion may comprise an ignition fuel housing and an ignition fuel, which is entirely contained within said exothermic cutting rod. The ignition fuel housing may have one or more windows that are configured to allow a heat source to ignite the ignition fuel, which then in turn ignites the fuel rods.Type: GrantFiled: November 22, 2019Date of Patent: August 23, 2022Assignee: Broco, Inc.Inventor: Diego Adolfo Torres

Patent number: 9452487Abstract: An exothermic cutting rod that comprises a tube and a plurality of wires. The wires may be cored wires that comprise various mixtures of powdered metals and other additives. The cored wires may be disposed within the inner circumference of the tube. The wires filled with powdered metals may allow the manufacturer to more quickly adjust the mixture ratios and develop a combination that has better performance characteristics, such as a reduced requirement of pure or substantially pure oxygen, or compressed gas.Type: GrantFiled: June 21, 2013Date of Patent: September 27, 2016Assignee: BROCO, INC.Inventors: David Dean McComb, Rodger W. Spriggs

Patent number: 5736711Abstract: An improved underwater arc-welding apparatus that includes a handheld torch assembly connected to an housing that delivers electrical power, a pressurized shielding gas, and a consumable wire electrode to the site of the weldment. The housing is configured such that the diver/operator, himself, can control such welding parameters as the voltage level of the electrical power, the duration of the flow of the shielding gas, and the delivery rate of the electrode. In addition, the housing is configured to allow the entry of water into the space between its components, and these components, including an electric motor that advances the consumable wire electrode, are sealed individually from the water. Electrical connections between the components are effected using underwater cables and connectors.Type: GrantFiled: January 12, 1996Date of Patent: April 7, 1998Assignee: Broco, Inc.Inventors: Thomas C. Joos, Taner Bayrak
