20100058900 | INSTALLATION TOOL FOR A THREADED OBJECT - A tool for installing a threaded object includes a bit or inner implement that has a tip for engaging a head of the threaded object, and a sleeve surrounding the inner implement for securing the threaded object to the tool during the installation process. The sleeve includes plural arms at least some of which have inner lips that engage the head of the threaded object to hold the head against the tip. The inner lips are chamfered to facilitate engagement and disengagement between the sleeve and the head of the threaded object. The sleeve is able to translate to a limited extent relative to the inner implement, in order to pull back and disengage from the threaded object head as the threaded object is received into a threaded opening. | 03-11-2010 |

20090305882 | Articles Comprising Tetragonal Zirconia and Methods of Making the Same - Described is a porous ceramic body comprising zirconia having mesopores incorporated therein and the primary crystalline phase is tetragonal. When used as a carrier for a catalyst, the porous ceramic body has excellent crush resistance and a large total pore volume which results in an increase in the carrier's surface area onto which catalytic material may be deposited. Methods of making the carrier are also disclosed. | 12-10-2009 |
20100279846 | PHASE STABLE METAL OXIDE ARTICLE AND PROCESS OF MAKING THE SAME - A shaped ceramic article, made from an amorphous metal hydroxide having a crystalline microstructure and at least 60 weight percent of the crystalline microstructure is tetragonal, is disclosed. The article's crush strength exceeds 4 kg. A process for making the ceramic article is also described. | 11-04-2010 |

20090270249 | METHOD FOR FORMING A CATALYST CARRIER - A method of forming a carrier material suited to use in Fischer-Tropsch reactions includes forming a dispersion of first and second hydrated alumina materials in a liquid dispersant, such as an acid solution. The first alumina can be derived from an alkali aluminate, such as is formed in the Bayer reaction. The second hydrated alumina can be derived from high purity aluminum, such as via conversion to an alkoxide. The dispersion is spray dried to form particles which are heat treated to form a carrier material having low levels of impurities. | 10-29-2009 |

20090294021 | PROCESS FOR MAKING A CERAMIC COMPOSITE DEVICE - An electrical power generating device having a plurality of ceramic composite cells, each cell having a cathode and an anode. A thermal shell in which the ceramic composite cells are stacked or arranged in electrical series and gas parallel surrounded by shock absorbing and insulating materials, respectively, is preferably included. Also provided are an exhaust fan, thermocouple sensors, a fuel supply, a programmable computer controller with user interface, and a container supporting the assembly and having passageways for providing air ingress and egress to the device, and power output terminals for the electrical power from the device. | 12-03-2009 |
