| 20080202913 | Method and Installation for Pyrolisis of Tires - The present invention relates to a method and apparatus for waste tyres pyrolysis wherein whole tyres are directly heated with flue gases from the combustion of pyrolysis gases, in a tunnel type furnace. The process produces thermal energy, carbon black and mineral oil; the cooled flue gases are cleaned from sulfur oxides before released into the atmosphere. | 08-28-2008 |

| 20090277308 | OPEN-FACED ROD SPINNER - An open-faced rod-spinning device configured for making and/or breaking joints between threaded drill rods. The rod-spinning device may include a drive gear with an open face. The drive gear may also be coupled to a plurality of drive pins. The rod-spinning device may include a carriage assembly including an open face for receiving and rotating about a drill rod. The carriage assembly may include a plurality of gripping lobes configured to be engaged and rotated by the drive pins about pivot pins. The drive gear may be configured to rotate relative to the carriage assembly to cause the drive pins to engage and rotate the gripping lobes. | 11-12-2009 |

| 20110232486 | Adsorbent Media with Li Exchanged Zeolite - An adsorbent media composition has a finished media lithium-exchanged zeolite X (LiX) with a finished Li content in a range from 96% to 83%, based on the total cation equivalents in the LiX. The adsorbent media composition is obtained from a slurry comprising water, a LiX precursor having a pre-media production Li content that is greater than the finished media LiX Li content, and another media component material, such as fibers. The water used to produced the media has a specific conductance in a range from 2.2 μSiemens/cm to 150 μSiemens/cm. The finished media LiX has a monovalent cation (Na, K, Rb, Cs and combinations thereof) in a range from 0.05% to 3%, based on the total equivalents of exchangeable cations in the finished media LiX. | 09-29-2011 |

| 20080222874 | HOT GAS DUCT AND DUCT SPLITTER ARRANGEMENT - A hot gas duct, such as a combustion casing in a gas turbine engine, includes a duct splitter held within the hot gas duct in at least three, preferably four, locations spaced around a peripheral edge of the duct splitter. At least one, preferably two, of the holding locations each comprise a generally cylindrical mounting that projects through a wall of the hot gas duct to engage an edge portion of the duct splitter by means of a slot formed in a circular face of the mounting. Mutually contacting surfaces of the slot and the duct splitter comprise hard face coatings to combat wear due to vibration and differential thermal expansion and contraction. The mountings have cooling holes that penetrate the mounting, so that coolant can flow through the mountings and into the interior of the hot gas duct to cool the mountings and the hard face coatings. | 09-18-2008 |
