| 20080223324 | Two-Step Rocker Arm Assembly - A two-step rocker arm assembly is provided having an arm member and a first roller assembly rotatably mounted with respect to the arm member and defining a generally C-shaped opening. A shaft member rotatably supports a second and a third roller assembly. The shaft member extends through the generally C-shaped opening and is selectively translatable therein to guide the second and third roller assemblies with respect to the arm member. A coupling lever is mounted with respect to the shaft member and is operable to selectively retain the shaft member with respect to the arm member for unitary movement therewith. | 09-18-2008 |
| 20080314347 | ROCKER ARM ASSEMBLY - A two step rocker assembly is provided having a lever body, a first roller assembly mounted to the lever body, and a center shaft extending through the first roller assembly. A second shaft extends through the lever body and defines a first pivot point. A coupling lever is pivotally connected to the second shaft and has an opening for receiving the center shaft. The coupling lever is rotatable about the first pivot point. A latch pin is mounted to the lever body. A second roller assembly is mounted on the center shaft. A spring lever is pivotally connected to the second shaft and is connected to the center shaft. The spring lever is rotatable about the first pivot point. A spring member is mounted on the lever body and engages the spring lever to bias the spring lever and the center shaft into the first position. | 12-25-2008 |
| 20100236525 | ENGINE ASSEMBLY INCLUDING CENTRALLY LOCATED FUEL RAIL - An engine assembly may include an engine block, a cylinder head, a fuel injector, and a fuel rail. The engine block may define a cylinder bore. The cylinder head may be coupled to the engine block and may define an intake port, an exhaust port, and a centrally located fuel injector opening between the intake port and the exhaust port. The fuel injector opening may be in direct communication with the cylinder bore. The fuel injector may be located within the fuel injector opening. The fuel rail may overlay the fuel injector opening and may be in communication with a fuel supply and the fuel injector. | 09-23-2010 |

| 20090145022 | COMBINED HOMOGENEOUS AND HETEROGENEOUS CATALYTIC TRANSESTERIFICATION PROCESS FOR BIODIESEL PRODUCTION - In one aspect, a process for producing a biofuel comprises reacting a feed material that comprises a glyceride with an alcohol in the presence of a catalytic composition such that at least some of the glyceride in the feed material is converted into a biofuel mixture that comprises glycerol and the corresponding alcoholic ester of the glyceride. The catalytic composition comprises a heterogeneous catalyst and a homogeneous catalyst. The heterogeneous catalyst and the homogeneous catalyst have a synergistic effect in catalyzing the reaction of the glyceride in the feed material with the alcohol. | 06-11-2009 |
| 20090307966 | ZnO NANOPARTICLE CATALYSTS FOR USE IN BIODIESEL PRODUCTION AND METHOD OF MAKING - A method of forming a biodiesel product and a heterogeneous catalyst system used to form said product that has a high tolerance for the presence of water and free fatty acids (FFA) in the oil feedstock is disclosed. This catalyst system may simultaneously catalyze both the esterification of FAA and the transesterification of triglycerides present in the oil feedstock. The catalyst system is comprised of a mixture of zinc oxide and a second metal oxide. The zinc oxide includes a mixture of amorphous zinc oxide and zinc oxide nanocrystals, the zinc nanocrystals having a mean grain size between about 20 and 80 nanometers with at least one of the nanocrystals including a mesopore having a diameter of about 5 to 15 nanometers. Preferably, the second metal oxide is a lanthanum oxide, the lanthanum oxide being selected as one from the group of La | 12-17-2009 |
| 20100010246 | METHODS AND CATALYSTS FOR MAKING BIODIESEL FROM THE TRANSESTERIFICATION AND ESTERIFICATION OF UNREFINED OILS - A method of forming a biodiesel product and a heterogeneous catalyst system used to form said product that has a high tolerance for the presence of water and free fatty acids (FFA) in the oil feedstock is disclosed. This catalyst system may simultaneously catalyze both the esterification of FAA and the transesterification of triglycerides present in the oil feedstock. The catalyst system according to one aspect of the present disclosure represents a class of zinc and lanthanum oxide heterogeneous catalysts that include different ratios of zinc oxide to lanthanum oxides (Zn:La ratio) ranging from about 10:0 to 0:10. The Zn:La ratio in the catalyst is believed to have an effect on the number and reactivity of Lewis acid and base sites, as well as the transesterification of glycerides, the esterification of fatty acids, and the hydrolysis of glycerides and biodiesel. | 01-14-2010 |
| 20100028977 | ENCLOSED PHOTOBIOREACTORS WITH ADAPTIVE INTERNAL ILLUMINATION FOR THE CULTIVATION OF ALGAE - The present invention provides an enclosed, internally-lighted bioreactor apparatus, methods for growing photosynthetic microorganisms in the enclosed, internally lighted bioreactor and methods for enhancing growth of a photosynthetic microorganism culture in the enclosed internally-lighted bioreactor. | 02-04-2010 |
| 20110067294 | EFFECT OF NATURAL AND SYNTHETIC ANTIOXIDANTS ON THE OXIDATIVE STABILITY OF BIODIESEL - Disclosed are biodiesel fuels with improved oxidative stability. Disclosed are biodiesel fuels which comprise two or more antioxidants which increase the oxidative stability of the biodiesel fuel. | 03-24-2011 |
| 20110209388 | CALCIUM AND LANTHANUM SOLID BASE CATALYSTS FOR TRANSESTERIFICATION - In one aspect, a heterogeneous catalyst comprises calcium hydroxide and lanthanum hydroxide, wherein the catalyst has a specific surface area of more than about 10 m | 09-01-2011 |
