| 20090260888 | Fiber Reinforced Pressure Compensator Diaphragm - A drill bit for drilling a wellbore, the drill bit having a body and at least one bearing. A rotary cone is rotatably attached to the bit body at the bearing. A lubricant reservoir is located in an inner portion of the bit body and is in fluid communication with the bearing. A communication port leads from the inner portion of the bit body to the exterior of the bit body. A fiber reinforced elastomeric pressure compensator diaphragm separates lubricant in the lubricant reservoir from the communication port. | 10-22-2009 |

| 20090270546 | Method of making shear thinning gels - The present invention relates generally to gels that flow through an orifice. Specifically the invention relates to gels that are dispensed through a trigger spray nozzle or aerosol spray valve. Still more specifically, the invention relates to nonaquious gels containing polymers whose instantaneous viscosity reversibly decreases when the gel experiences shear loads. The invention includes spray gel compositions, methods of making spray gels and methods of dispensing gels whose viscosity exhibits an instantaneous temporary decrease in viscosity when the gel is subjected to shear force as happens when it flows through an orifice, such as a spray nozzle or aerosol valve. | 10-29-2009 |

| 20080263941 | Reduced vapor pressure gelled fuels and solvents - The present invention relates generally to gelled fuels and solvents. Specifically the invention relates to gel thickeners that reduce vapor pressure in fuels and solvents and are shear thinning (pseudoplastic or thixotropic) or are shear thickening and remain pourable and flowable. Still more specifically, the invention relates to nonaqueous gels made with diblock copolymers that reduce the Reid Vapor Pressure of gelled gasoline and lower the total volatility of gelled hydrocarbon solvents. These gels may contain secondary amino acid or triblock polymer gelling agents. The invention includes gel compositions and methods of making gels. | 10-30-2008 |
