20100206417 | Device And Method For Repairing A Pipeline - A method for repairing a pipeline by means of at least one shell that is adapted to the outer contour of the pipeline, wherein the at least one shell is attached to the outer wall of the pipeline using an intermediate layer between the interior of the shell and the outer wall of the pipeline. The intermediate layer is made of an adhesive that can be activated, which is used to substantially completely coat the interior of the at least one shell. The attachment of the shell is carried out by applying a force acting at least in the radial direction, and the activation of the adhesive. A shell that is coated in this manner is also disclosed. | 08-19-2010 |
20100206418 | METHOD FOR CONNECTING PIPES AND PIPE HAVING A PROFILED FACE END - A pipe, particularly a pipeline pipe having a first and a second face end, wherein the two face ends are profiled such that two identically profiled pipes can be connected to each other by way of a glued plug-in connection of a first face end of one pipe to the second face end of the second pipe, wherein the plug-in connection has a centering section and a gluing section, wherein a stop step of the first pipe abuts a counter stop step of the second pipe in the centering section such that an annular gap, which is open toward the outside of the pipes and is filled with glue in the connected state, is formed in the gluing section. It is essential that the annular gap is formed by two gap walls extending substantially parallel to each other and tilted at an acute angle to the pipe axis. | 08-19-2010 |
20110132940 | WIDE-SLOT NOZZLE - A device for applying a flowable medium onto a level workpiece surface, including a housing forming an elongated outlet nozzle for the medium and an essentially cylindrical media distributor which is rotatably arranged in the housing and includes a slot that changes its position relative to the outlet nozzle by rotating the media distributor and whose outer surface forms sealing surfaces which rest sealingly against sealing surfaces of the housing. In order to develop the device such that low- to medium-viscosity media can be applied with a closed surface onto a level workpiece surface, the media distributor is a pipe whose interior is formed by a reservoir that can be fed with the medium via a feed opening and that the slot extends in such a manner that, by rotation of the media distributor, it can be brought from an open position, in which it forms an open, continuous opening essentially over its entire length from the reservoir to the outlet nozzle, to a closed position in which the continuous opening is completely closed. | 06-09-2011 |
