| 20090250837 | METHOD OF MANUFACTURE OF A NUT AND TAIL ASSEMBLY - A nut and tail assembly and method of manufacture including a nut having a first end and an inward flange at the other end, a longitudinal cylindrical hollow body having a first end and a second end at which is located an outstanding flange and a circular longitudinal sleeve. The sleeve extends along said sliding surface and has a flange at a first end abutting against the body flange. A stop is located between the ends of the body and defines a cavity sliding surface generally parallel to the longitudinal body between the stop and flange. The nut inward flange extends into the body cavity and is of large enough diameter to be able to slide on said body sliding surface, but small enough to be held within said cavity defined between said stop and sleeve flange. Projections on the sleeve flange assist in locating the sleeve relative to the nut during the moulding process. | 10-08-2009 |
| 20090127803 | Pipe Coupling Adapted for Sealing the End of a Pipe - The present invention relates to a sealing member for use in a pipe coupling assembly and, in particular, to a sealing member for sealing the end of a pipe having an exposed metal surface at its end, such as pipes comprising an internal metal sheath which is lined internally and externally with plastic. The sealing member includes a pipe receiving portion adapted to receive the end of the pipe to thereby prevent contact between the end of the pipe and fluid travelling through the pipe. The sealing member may be used in standard pipe couplings, or is preferably incorporated into a coupling having a deformable gripping member whereby upon tightening of the coupling assembly nut, the gripping member urges against the pipe both radially and longitudinally to thereby simultaneously grip the pipe and urge the pipe end within the pipe receiving portion. | 05-21-2009 |
