| 20120112375 | METHOD AND MEANS OF LINING A MANHOLE - An apparatus and method is provided for lining the wall of a manhole. The apparatus may include a liner assembly, which includes an expansion device, an auxiliary bladder, a primary bladder, and a liner. The auxiliary bladder is first inflated near the top of the manhole. Next the primary bladder may be expanded to press the liner against the wall of the manhole. The liner, being impregnated with a resinous material, is pressed against the wall until the resinous material cures and hardens. The expansion device, auxiliary bladder, and primary bladder are then removed from the manhole. The result is a repaired manhole wall. | 05-10-2012 |
| 20120084957 | APPARATUS AND METHOD FOR REPAIRING THE JUNCTION OF A SEWER MAIN AND LATERAL PIPE - The present invention is directed to methods for repairing pipes or pipe junctions. The methods include providing a launcher device having a bladder and a liner impregnated with a material capable of curing and hardening. The bladder includes a first end, a closed second end, and an opening proximal the closed second end. A portion of the bladder is positioned within the launcher device, a rope or a line is connected to the liner, and the rope or line is threaded through the opening in the bladder. The rope or the line is pulled until the liner is at least partially within the bladder, and the rope or line is removed. The pipe is repaired by positioning the liner against the wall of a pipe, and allowing a material capable of curing and hardening to cure and harden. The methods allow for the rapid reuse of the bladder. | 04-12-2012 |
| 20120084956 | APPARATUS AND METHOD FOR REPAIRING THE JUNCTION OF A SEWER MAIN AND LATERAL PIPE - The present invention is an improved method and assembly for repairing a pipe or the junction of two pipes, such as sewer pipes. The assembly includes a launcher device having a launcher device body, a launcher device opening disposed on the launcher device body, and a main bladder substantially surrounding the launcher device body. The main bladder includes an opening that substantially aligns with the launcher device opening. The assembly further includes an absorbent liner and a lateral bladder having a tubular lateral bladder body portion and a flange portion. The flange portion of the lateral bladder is attached to the exterior of the launcher device body. A method of using the assembly includes impregnating the liner with resinous material; inserting at least a portion of the liner into the lateral bladder; inflating the bladders; pressing the liner against the pipe; and allowing the resinous material to cure and harden. | 04-12-2012 |
| 20120009020 | MANHOLE LINER AND METHOD OF USING THE SAME - A manhole liner and a method of using the same are provided. The manhole liner is sized substantially equally to the largest diameter of the manhole, so that the liner does not have to stretch to be pressed against the manhole wall. Additionally, the liner is impregnated with a resinous material capable of curing and hardening. A bladder, preferably stretchable circumferentially and having a diameter less than the smallest diameter of the manhole, is inserted into the liner. The bladder is expanded to press the liner against the wall of the manhole to dispense resinous material from the liner, while the liner is able to fold over itself in areas having a diameter less than the original diameter of the liner. Because the bladder stretches to produce a smooth outside surface, the resinous material will migrate to areas in the folds and will cure with a smooth interior surface. | 01-12-2012 |

The liner assembly includes a first and second camera and a containment bladder all operably connected to a launcher device, and which are used in combination by a user in a remote location to position and align the liner assembly in a main pipe, adjacent a lateral pipe, wherein no external access to the lateral pipe is available. The user will use images from the cameras to send control information to a positioning device, which positions and aligns a liner assembly with a lateral pipe. The liner assembly is then used to repair damage to the lateral pipe and the juncture between the main and lateral pipes. | 01-12-2012 |
| 20120006439 | METHOD AND MEANS FOR FORMING A LINER - A new liner and method of forming a liner for use in lining the junction between a main pipe and a lateral pipe are provided.

The material is pressed into fractures and the bladder remains inflated until the material cures and hardens, leaving a newly lined pipe. An assembly for forming the lining in the pipe includes a dispensing hose, a dispensing unit, and a bladder. | 12-08-2011 |
