Patent number: 10237928Abstract: An embodiment disclosed herein includes a monolithic graphite electrode. The electrode has a main body having a length of more than 3050 mm. Another embodiment disclosed herein includes an electrode column comprising a plurality of monolithic graphite electrodes. The column has a length of more than 3050 mm of electrode per joint. A further embodiment discussed herein is the practice of increasing the length of the electrode to minimize the occurrence of an electrode joint in the electrode column for a given length. This practice will improve efficiencies for both electrode manufacturers as well as electric arc furnace operators.Type: GrantFiled: April 3, 2008Date of Patent: March 19, 2019Assignee: GrafTech International Holdings Inc.Inventors: Diane M.

Patent number: 9588023Abstract: A method and apparatus for the collection, transportation and analysis of gas samples which may be required in various scientific, environmental and natural resource contexts is provided. The apparatus comprises a sampling container assembly for sampling a fluid. The container assembly comprises a body defining a sampling chamber having a first end and a second end, a first valve assembly fluidly coupled with the first end and a reactant material positioned within the sampling chamber for reacting with the fluid. After collection of the sample in the sampling container assembly, hazardous fluids are converted to non-hazardous materials that can be transported without additional hazardous material restraints. Further, the flow through design of the sampling container assembly allows for the collection of gases such as H2S at low concentrations by flowing the gas over the reactant materials for longer periods of time.Type: GrantFiled: March 10, 2015Date of Patent: March 7, 2017Assignee: Weatherford Switzerland Trading and Development GMBHInventors: Todd Coleman, Corben Rice, Dennis Coleman

Patent number: 9187698Abstract: A method of processing light fraction tar includes pre-heating the light fraction tar before directing it through a reactor. The reactor has a top and a bottom and a surface spanning between said top and said bottom. A film of the light fraction tar flows down the surface under the force of gravity and with heated gas blowing thereon. The portion of the film that reaches the bottom of the reactor has improved properties making it more widely useful for carbon products.Type: GrantFiled: November 11, 2011Date of Patent: November 17, 2015Assignees: Graftech International Holdings Inc., JPMorgan Chase Bank N.A., as collateral agentInventors: Chong Chen, Philip Dennis Coleman

Patent number: 8522599Abstract: A canister for measuring the natural gas content of rock cores which (1) has an inner core-containment bag made of non-permeable plastic which can be flash evacuated, collapsing around the core and thus minimizing the amount of air present and improving the quality of the gas analyses and (2) which prevents the released gas from reacting with the outer canister. A procedure for using gas-sampling bags to periodically collect the gas released from the core so that (1) the volume of released gas can be measured at a later date using more convenient and precise laboratory methods, (2) the gas can be readily transported and stored, and (3) the gas can be easily submitted for analysis.Type: GrantFiled: April 17, 2009Date of Patent: September 3, 2013Assignee: Isotech Laboratories, Inc.Inventors: Dennis Coleman, Coleman Todd

Publication number: 20120111740Abstract: A gas sampling container capable of obtaining, isolating and transporting samples of gas or other fluid under pressure form. The container further exhibits a plurality of simple, reliable, inexpensive, self sealing, valves which allow the introduction, flow through and exit of the gas sample. The container is suitable for taking discrete or serial samples from a gas or fluid flow source and is especially suited for use in automated sampling apparatus. These containers are acceptable for shipment of compressed flammable gases under the regulatory structures of many countries.Type: ApplicationFiled: October 27, 2011Publication date: May 10, 2012Inventors: Todd Coleman, Dennis Coleman

Publication number: 20120066860Abstract: A blast gate to control the application of vacuum pressure to a particulate generating machine so that particulate may be drawn away from the machine and isolated in a vacuum container. The blast gate may be opened when either a vacuum or particulate generating machine is switched on. The blast gate is designed to be inserted in a duct leading from the vacuum to the particulate generating machine. The electromechanical design allows two switches to be activated by a mechanical rotating arm. The switches respectively allow the gate to be held in the open position or in the closed position as well as activating the mechanical arm whereby the gate is moved to the open or closed position.Type: ApplicationFiled: June 9, 2011Publication date: March 22, 2012Inventors: Dennis Coleman, Gavin Steele

Publication number: 20100083771Abstract: The object of this invention is to provide a gas sampling system capable of taking discreet samples from a continuous flow of gas or fluid. Said apparatus offers a frame (1) and mounting components in the form of a fixed chuck (4) and a spring-loaded chuck with a sample container (5) mounted there between. The sampling container has self-sealing end cap valve assemblies (76) that automatically open when the sample container (5) communicates with the fixed chuck (4) and the spring loaded chuck (6) and the end cap valve assembly automatically closes when the sample container is removed. A value system allows the gas flow to be directed from one sample container to the other alternatively opening and closing a gas flow path. A sample extraction assembly (14) allows the efficient removal of samples from the sample containers.Type: ApplicationFiled: December 4, 2009Publication date: April 8, 2010Inventors: Dennis Coleman, Todd Coleman
