| 20090305391 | Triphasic bioreactor and process for gas effluent treatment - A triphasic bioreactor for physico-chemically treating a gas is disclosed. The triphasic bioreactor comprises a reaction chamber with a liquid and biocatalysts in suspension in the liquid, for catalyzing a reaction between the gas and the liquid to obtain a treated gas and a solution containing a reaction product. A gas bubbling means is provided in the reaction chamber for bubbling the gas to be treated into the liquid thereby dissolving the gas into the liquid and increasing a pressure inside the reaction chamber. The bioreactor further comprises a liquid inlet in fluid communication with the reaction chamber for receiving the liquid and filling the reaction chamber, a liquid outlet in fluid communication with the reaction chamber for releasing the solution and a gas outlet in fluid communication with the reaction chamber to release the treated gas. The bioreactor further comprises a retention device to retain the biocatalysts in the reaction chamber. The invention also concerns a process using the triphasic bioreactor. The triphasic bioreactor may advantageously be used for removing carbonic dioxide from a CO | 12-10-2009 |

| 20100147646 | PULLEY WITH ASYMMETRIC TORQUE-SENSITIVE CLUTCHING - A pulley assembly for use in an automobile accessory drive system includes a shaft engaging hub, a pulley member, a nut treaded onto the shaft engaging hub, and a brake member interposed between the pulley member and the nut. The shaft engaging hub is engaged with an accessory input shaft for rotation therewith. Frictional engagement between the pulley member, the brake member, and the nut transfers torque from the pulley member to the input shaft. The pulley member includes an inner coupling surface and a peripheral belt-engaging surface. The nut includes an outer coupling surface. The brake member includes a first coupling surface in frictional engagement the outer coupling surface of the nut and a second coupling surface in frictional engagement with the inner coupling surface of the pulley member. When torque is applied to the nut in a first direction the out coupling surface of the nut couples to the inner coupling surface of the brake member such that the hub and the nut rotate with the pulley member. The outer coupling surface of the nut and the inner coupling surface of the brake member decouple when torque applied to the nut is in a second direction opposite the first direction such that the hub rotates relative to the pulley member. | 06-17-2010 |
| 20110198185 | Pulley With Asymmetric Torque-Sensitive Clutching - A pulley assembly for an automobile accessory drive system includes a shaft engaging hub, a nut threaded onto the shaft engaging hub, an annular bushing, and one or more brake shoes positioned around the outside of the annular bushing all housed with a pulley member. The nut is capable of axial translation relative to the annular bushing and the annular bushing is capable of expanding radially outward in response to the axial translation of the nut in a first direction to provide frictional engagement between the inner coupling surface of the pulley member and the outer coupling surface of the brake shoes, which transfers torque from the pulley member to the input shaft. The nut includes a generally frustoconical outer surface, opposite its inner threaded surface, for seating the nut in the annular bushing. | 08-18-2011 |
