| 20100075191 | Textured solid oxide fuel cell having reduced polarization losses - An improved SOFC including textural features pressed into a structural anode and electrolyte bi-layer laminate to increase the active surface area of the finished fuel cell anode and cathode. This arrangement reduces current losses from ohmic, concentration, and activation polarization. In a presently preferred embodiment, an array of dimples is formed during manufacture of the bi-layer laminate by isostatically pressing an array of steel balls against the laminate before firing thereof. The dimples or other features may be varied in depth and spacing as may be desired to optimize gas flow through the SOFC and fuel efficiency thereof. The array may be close-spaced or not and may have any desired geometric packing form, including rectangular and hexagonal. | 03-25-2010 |

| 20100150816 | Methods for Purifying an Aqueous Hydrochloric Acid Solution - Methods for purifying an aqueous hydrochloric acid solution waste stream having an impurity fraction comprising an initial Ti fraction, an initial S fraction and an initial Si fraction; that provide purified aqueous hydrochloric acid solutions having a final Ti fraction of less than 250 ppm, a final S fraction of less than 200 ppm, and a final Si fraction of less than 10 ppm, which may be determined with inductively coupled plasma spectroscopy. Process steps in various embodiments include sparging with an gas; mixing the sparged solution with a precipitation agent comprising a sufficient amount of an alkali earth metal salt and, optionally, a phosphoric acid source, to provide a metal salt precipitate; and mixing the initial aqueous acid solution or, optionally, the sparged aqueous acid solution, with a flocculating polymer. A preferred alkali earth metal salt is barium chloride and preferred flocculating polymers are poly(diallyldialkylammonium chloride) homopolymers and copolymers. | 06-17-2010 |

| 20090118465 | PREPARATION OF POLYTRIMTHYLENE ETHER GLYCOL OR COPOLYMERS THEREOF - This invention relates to a process for preparing polytrimethylene ether glycols or copolymers thereof by a polycondensation reaction using at least one acid catalyst, wherein the temperature of the reaction is controlled such that the average temperature during the first half of the reaction is higher than the average temperature during the second half of the reaction. | 05-07-2009 |

| 20080313904 | Three-piece lower manifold for a V-style engine intake manifold - A lower manifold for a V-style internal combustion engine comprising at least three shells: a top shell for mating with an upper manifold; a left shell for mating with a left engine head; and a right shell for mating with a right engine head. The three shells are formed independently by injection molding and are joined as by vibration welding when aligned in a welding jig. The molds for the left and right shells are formed such that the seal ring groove has a rectangular cross-section having sidewalls perpendicular to the lower shell surface because each left and right shell has its own draft angle preferably perpendicular to its lower shell surface. The method and apparatus of the invention permits runner cross-sections to be significantly rounded, which improves air flow characteristics of the runners. | 12-25-2008 |
| 20080314352 | Edge-pivot charge-motion control valve system for an internal combustion engine manifold runner - An edge-pivot charge-motion control assembly for controlling air turbulence comprising a molded sleeve inserted into a runner port of an intake manifold of an internal combustion engine. A control valve element is pivotably mounted in the sleeve for external actuation. The valve element pivots into a formed recess in a wall of the sleeve and thus may be fully removed as desired from the air stream. The system allows customizing of the valve shape and also the entrance and exit geometry of the runner sleeve as desired for any engine intake manifold, thus affording great flexibility in use with a series of engines of various displacements using essentially the same head. The charge motion function between engines, and even between runners in a given engine, can be changed inexpensively by changing a small, relatively inexpensive mold tool, rather than a large, very expensive manifold mold tool. | 12-25-2008 |

| 20100102609 | Vehicle Seat Assembly - A lift truck includes a seat assembly having a first frame and a seat bottom pivotably mounted to the frame for pivotable movement between a standing operating position and a sitting operating position. The seat bottom has an upper facing surface for supporting an operator sitting on the seat bottom when the seat bottom is in the sitting operator position and a lower surface facing outwardly when the seat bottom is in the standing operator position for supporting an operator leaning against the seat bottom. | 04-29-2010 |
