| 20110074115 | Injection of sealant for pressure sealant type rotary seal - An insert for a pressure sealant type sealing system, an improved sealing system for sealing between an aperture of a machine housing and a rotating shaft of the machine protruding through the aperture, comprising the insert to provide a pair of outlets into the driveshaft arranged collinearly around the driveshaft, a method of injecting the sealant into the stuffing box in two positions on opposite sides of the drive shaft thereby balancing the pressure, and a method of retrofitting existing pressure sealant systems by retrofitting with the insert. | 03-31-2011 |
| 20090194951 | Cooling system for injection sealant stuffing box - A conduit for a cooling liquid, said conduit for substantially contacting a viscous fluid type sealant within a stuffing box, thereby conducting heat away from said sealant within said stuffing box by flowing said cooling liquid though said conduit. | 08-06-2009 |
| 20090194949 | Shaft for viscous sealant systems - A sealing system for sealing between an aperture of a machine housing and a rotating machine-shaft protruding through the aperture, said sealing system comprising: (i) a stuffing box for encasing the aperture of the machine housing and a segment of said shaft and, (ii) a viscous fluid type sealant within said stuffing box, wherein the shaft is concentric about its axis of rotation and said segment has at least one variation in its effective external diameter thereby increasing the surface area thereof, in contact with the liquid sealant. | 08-06-2009 |
