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 |

20160015480 | DENTAL MATRIX CLAMP - A ring clamp matrix system utilizes a split ring spring with a pair of feet, one mounted to each end of the ring. At least one of the feet includes a wedging surface for engaging and holding a sectional matrix foil. Each foot is positioned outwardly from the interproximal space as the ring clamp is being installed between two adjacent teeth, to have each foot exert a force inward against the teeth and foil under the force of the spring when the spring is permitted to retract to its natural shape. A pair of juxtaposed extensions, each extend in the orthogonal direction, respectively inwardly towards each other from the bottom of each foot. These extensions are retained in position by the respective curved surfaces of the teeth to force the foil against one of the two teeth and positively lock the ring clamp from moving out of position. | 01-21-2016 |
