| 20080284162 | Pipe coupling - A clamping assembly for joining pipe comprising a clamping band formed with a first retaining area and a second retaining area, having an axial split forming a first and second edge and a first tab disposed along the first edge of the axial split and a second tab along the second edge of the axial split, a first worm gear clamp for securing the clamping band to a first pipe section, a second worm gear clamp for securing the clamping band to a second pipe section, and at least one bolt for securing the first tab to the second tab for providing a sealed coupling of the first tab to the second tab and the first edge to the second edge, wherein coupling the first tab to the second tab provides for a seal of the first edge and the second edge such that the pipe join is sealed. | 11-20-2008 |
| 20090079186 | FLEXIBLE FITTING FOR RIGID TUBING ASSEMBLY - A flexible fitting for connecting a plurality of rigid tubings to form a tubing assembly including a housing, having a plurality of bores defined therein and a plurality of tube fittings, each fixedly attached to an end portion of one of the plurality of rigid tubings and disposed therein one of the plurality of bores. Each of the plurality of tube fittings includes an o-ring channel having an o-ring disposed therein and in sealing contact with a sidewall of the housing when the flexible fitting is assembled. The combination of the tube fittings and the o-rings permit movement of tubing assembly, and more particularly the rigid tubing, about an axis of the tube fitting, translation along the axis of the tube fitting, and provide angulation of the rigid tubing relative to the housing. | 03-26-2009 |
| 20090230675 | Cuff seal using single clamp - A cuff seal may include an annular body having an outer radial portion, an inner radial portion, and an end portion; an annular groove disposed between the outer radial portion and the inner radial portion; and a clamp disposed around the outer radial portion, the clamp being adapted to constrict the annular body. The outer radial portion, the inner radial portion, and the end portion form a U-shaped cross-section defining the annular groove, and the annular groove includes an open end and a closed end. | 09-17-2009 |
| 20100253071 | THERMOPLASTIC ELASTOMERIC ATTACHMENT SYSTEM FOR TRANSFER OF PARTICULATE MATERIALS - A system for attaching a thin film sleeve to a drum using a flange made of thermoplastic material. The inner surface of the flange having an integrally molded portion, where the integrally molded portion is used to create a seal with a different thermoplastic material. The second thermoplastic material can be attached to the drum, thereby forming a seal between the drum, the second thermoplastic material, and the flange. The outer surface of the flange being integrally sealed with the thin film sleeve, thereby creating a barrier between any product being transported through the sleeve to the drum. | 10-07-2010 |
| 20140353963 | Telescoping Pipe Connector - A pipe connector comprises a first pipe section | 12-04-2014 |
| 20150137509 | CLAMP APPARATUS HAVING INDEXING FEATURE - A clamp apparatus is disclosed which has a duct having an indexing feature formed thereon. A wire clamp is provided which has a length of resilient spring material shaped generally in accordance with a cross sectional configuration and diameter of the duct. A tightening component is operatively coupled to the length of resilient spring material. A portion of the wire clamp engages with the indexing feature to enable the wire clamp to be positioned and held in a desired angular orientation on the duct while being tightened on the duct using the tightening component. | 05-21-2015 |
