| 20090155000 | GROUT AND LIFTING TUBE - A grout and lifting tube for casting within a concrete segment. The tube provides enhanced sealing between the tube and the concrete to prevent moisture leakage into a structure formed by a plurality of the concrete segments. The tube includes a generally cylindrical body having an exterior with an anchoring rib structure, a threaded interior, a proximal end, a distal end. An annular gasket is disposed at the proximal end of the tube body, and may be secured to the proximal end of the tube body by a mechanical interlock and/or by unitary co-molding. After the concrete section is placed and grout is pumped through the tube, a plug is threadable into the proximal end of the tube to both compress the gasket between the plug and the tube at a first seal, and to compress the gasket between the plug and the concrete surrounding the proximal end of the tube at a second seal to provide robust, watertight sealing. | 06-18-2009 |
| 20110024993 | GASKET AND MANDREL ASSEMBLY FOR PIPE JOINTS - A gasket and mandrel assembly, including a gasket having an annular main body portion with an anchor flange and a pipe sealing portion. The gasket is foldable between a folded position in which the pipe sealing portion is disposed substantially within the main body portion and an unfolded position in which the pipe sealing portion extends outwardly of the main body portion along its longitudinal axis. A pair of mandrels are respectively fitted on opposite sides of the folded gasket to enclose most of the gasket for casting the gasket within a wall in a concrete structure. At least one of the mandrels includes an annular outer surface aligned parallel or substantially parallel with the longitudinal axis of the gasket. Removal of the mandrels results in the cast opening in the concrete structure having a circular inner surface which is disposed parallel or substantially parallel to the longitudinal axis of the gasket and the resulting opening such that, if the gasket should fail, the gasket may be removed from the opening and an expansion-type gasket may be sealingly compressed against the opening surface with an expansion band assembly. | 02-03-2011 |

| 20090208893 | Insertion, Devices, Methods and System for Use in Dentistry - A dental insertion for a tooth filling, the insertion having a surface and a body extending from the surface, wherein at least one cavity is arranged in the surface, the cavity extending at least from the surface to a center of the body. Further, a dental insertion dummy having similar dimensions to a dental insertion, a device for handling of a dental insertion, a device of an electromagnetic radiation-conducting material for insertion into a dental insertion, a method for incorporating a dental insertion for a tooth filling into an interproximal space, a system including one or more of the insertions and devices and a method for production of insertions for dental treatment. | 08-20-2009 |
