In accordance with the structure, because the locking unit is designed direcly on the locking end to make water can be guided directly and vertically to the locking screw cap and perforation and position the water faucet on the shutter of the granite counter, the interval between the shutter and wall can be shortened properly for saving space and costs in connection materials.Type: GrantFiled: June 3, 2005Date of Patent: March 6, 2007Inventor: Chiu-Chih Chung

Patent number: 7159906Abstract: Embodiments of the invention, can utilize a flange system incorporating metal sealing. In a further specific embodiment, the subject invention can utilize stainless steel sealing, where the flanges and seals are stainless steel. The subject seal may be made and released and remade multiple times. In a specific embodiment, the subject seal may be unaffected by heat extremes and more resistant to corrosive environments than copper and other soft metal seals. The subject invention can utilize sexless flanges, so as to avoid male/female design problems and can utilize infinitely rotatable flanges. The subject infinitely rotatable flanges eliminate bolt hole alignment problems, such that rotatable bolted flanges are not needed.Type: GrantFiled: February 2, 2004Date of Patent: January 9, 2007Assignee: A&N CorporationInventors: June E.

Patent number: 7014225Abstract: A pipe and snap connector assembly including mating male and female pipes joined by a clam-shell type connector. The female pipe receives a portion of the male pipe, and each pipe provides a radial flange configured such that there is a gap between the radial flanges when the male pipe is received in the female pipe. A sealing washer or seal is disposed between the flanges, in the gap. The clam-shell type connector is of open-ended barrel construction, and includes a radial clamp cavity that is sized to contact the radial flanges on the male and female pipes and axially compress them against the seal to provide a fluid-tight connection of the pipes. A latch and catch mechanism on the connector can be opened and closed without the use of special tools.Type: GrantFiled: September 7, 2004Date of Patent: March 21, 2006Assignee: Viking Plastics, Inc.Inventors: Kelly J. Goodsel, Ernest Lane, Jr., Cyrus D. Gilson, Michael Hiner

Patent number: 6979025Abstract: A metal pipeline section that has a metal flange at one end is lined with a plastic liner such that some of the liner extends beyond the flange end of the pipeline section. An annular plastic member is electrofusion joined onto the outside of the portion of plastic liner which extends beyond the flange end of the pipeline section and any liner extending beyond the annular plastic member is trimmed off to make the liner flush with the annular plastic member. The annular plastic member is then positioned adjacent the annular plastic member of another similarly prepared pipeline section and a containment ring is secured around them to restrain any outward movement of the annular plastic members when the pipeline is in use. The metal flanges are secured to each other such that the annular plastic members are compressed between them to prevent leakage.Type: GrantFiled: December 7, 2001Date of Patent: December 27, 2005Assignee: Lattice Intellectual Property Ltd.Inventors: Robert John Conder, Zahid Ahmed Shah

Patent number: 6942220Abstract: The present invention provides a combination metal gasket that is formed by fitting a ring-shaped metal base elastic structure in at least one trough portion of two trough portions of a ring-shaped metal gasket that has an S-shaped longitudinal cross section. The combination metal gasket does not demonstrate the plastic deformation even when a large compressive load is applied and is not likely to be destroyed even when a pressure of a fluid being sealed is high; that is, stable sealing properties are exhibited.Type: GrantFiled: January 5, 2004Date of Patent: September 13, 2005Assignee: Nichias CorporationInventors: Kenichi Takahiro, Hideaki Mori, Kanji Hanashima
