| 20110296894 | FLANGE-FORMING SYSTEM FOR TUBE AND RELATED METHODS - A system is configured for forming a flange at an end of a tube. The system includes a collar configured to receive the tube. A first roller engages the collar and a second roller is configured to cooperate with the first roller to rotate the collar and the tube. A rotatable cam is disposed about the second roller and includes a cam surface configured to bend the end of the tube to thereby form the flange. The collar may be configured to restrict axial movement of the tube relative to the collar. Additionally or alternatively, the collar may be configured to restrict rotational movement of the tube relative to the collar. | 12-08-2011 |

| 20100038902 | Tube Coupling and Related Methods - A juncture assembly is provided between first and second ends of respective first and second tubes. The assembly includes a first flange that is located at the first end and a second flange that is located at the second end, with the second flange being in confronting relationship with the first flange. The first and second flanges define a gap between them. A gasket member contacts the first and second flanges and is configured to prevent flow of fluids through the gap. A clamp member of the assembly secures the gasket member to the first and second flanges with the clamp member including a channel for receiving the first and second flanges and first and second restriction elements that extend into the channel for positioning the first and second flanges within the channel. | 02-18-2010 |
| 20090085349 | DUCT SYSTEMS AND RELATED METHODS - A juncture assembly between first and second tubes includes first and second flanges formed at the ends of the tubes. The flanges include respective legs in a confronting relationship and defining a gap between them. A gasket member contacts the flanges and is configured to prevent travel of fluids through the gap. The gasket member may, for example, be disposed in the gap between the first and second legs. | 04-02-2009 |
