| 20120124804 | SLIP ON GROOVE COUPLING WITH MULTIPLE SEALING GASKET - Methods, gaskets, and couplings for connecting two pipes are disclosed. One embodiment of the method includes the steps of placing the assembled coupling over one end of a pipe, aligning the second pipe with the first pipe, sliding the coupling off the end of the first pipe so that a portion of the coupling is around each pipe, and securing the coupling. | 05-24-2012 |
| 20120097283 | RESILIENT PLUG APPARATUS AND METHOD OF USE - Systems, apparatuses, and methods of use of a plug assembly are disclosed herein. The plug assembly includes an expandable plug for use with a pipe having an annular wall defining an outer wall surface and an inner wall surface. | 04-26-2012 |
| 20120090697 | NON-INTERRUPT METER CHANGE OUT - Disclosed is a non-interrupt meter change out device including a clamp assembly, at least one case assembly, and at least one collar, the clamp assembly including a frame and a distance adjuster. | 04-19-2012 |
| 20120011929 | Plastic Water Meter with Metal Threads - Embodiments of the present invention generally relate to flow meters and more particularly to improved plastic water flow meters for commercial or residential use. In various embodiments, a plastic water meter is provided that may include metal threads for connecting the water meter to a water system. In particular, the plastic water meter may include at least one spud that is shaped to receive and engage a plastic spud insert, in which the plastic spud insert may include a metal ring with a threaded outer surface. The plastic spud insert may include an annular lip portion extending outwardly to discourage removal of the metal ring when the spud insert is engaged with the water meter. Furthermore, the plastic spud insert and the inner surface of the metal ring may have complementary circumferential profiles to discourage relative rotation between the metal ring and the spud insert. | 01-19-2012 |
| 20110308646 | MECHANICAL POSITION INDICATOR - A check valve position indicator assembly is disclosed including an indicator housing, an indicator shaft rotably disposed in the indicator housing, an indicator arm attached to the shaft, a rod attached to the shaft, a mounting bracket, an indicia member attached to the mounting bracket, and at least one fastener attaching the indicator housing with the mounting bracket. In some embodiments, a seal is included along the bottom of the indicator housing. | 12-22-2011 |
| 20110308638 | INFRASTRUCTURE MONITORING DEVICES, SYSTEMS, AND METHODS - An infrastructure monitoring system and method include multiple communications devices. At least one communications device is coupled to an element of the infrastructure. | 12-22-2011 |
| 20110285093 | SIMPLIFIED LOW INSERTION FORCE SEALING DEVICE CAPABLE OF SELF RESTRAINT AND JOINT DEFLECTION - A conduit coupling system, sealing device, bell and method of use are disclosed herein. The system comprises at least two piping components, and a sealing device. A first component has a bell and a second component has a spigot, the spigot is adapted to mate with the bell. The bell comprises a first end and a second end, the first end coupled to the first component. The bell has a concave annular inner surface and a diameter of the annular inner surface adjacent to the first end of the bell is greater than a diameter of the annular inner surface adjacent to the second end of the bell. The sealing device comprises a locking segment comprising a convex outer surface and a K-type gasket coupled to a locking segment or a non-restraining anti-extrusion segment. The sealing device is adapted to fit between the bell and the spigot. | 11-24-2011 |
| 20110210543 | Pipe Coupling Device - Disclosed is a device for coupling a male piping member to a female piping member including a compressible sealing gasket and a gripping ring surrounding the male piping member, the gripping ring including at least one gripping member and at least one overlapping surface; an intermediate ring surrounding the male piping member, the intermediate ring at least partially overlapping the overlapping surface of the gripping ring, the intermediate ring communicating with the compressible sealing gasket; and a locking ring surrounding the male piping member and communicating with the gripping ring, wherein through a tightening connection between the locking ring and the female piping member, the locking ring communicates with the gripping ring forcing the intermediate ring into the compressible sealing gasket to form a seal between the male piping member and the female piping member and subsequently to force the gripping ring to grip the male piping member. | 09-01-2011 |
| 20110209775 | SIMPLIFIED LOW INSERTION FORCE SEALING DEVICE CAPABLE OF SELF RESTRAINT AND JOINT DEFLECTION - A method of use of a conduit coupling system, sealing device, and bell are disclosed herein. The method comprises positioning a sealing device inside a bell coupled to one end of a first conduit, inserting a spigot of a second conduit through the sealing device inside the bell, wherein the sealing device is adapted to move axially within the bell in the direction of the insertion of the spigot and in a radial direction from a centerline of the conduit, and partially removing the spigot from the bell, wherein a segment of the sealing device engages the outer surface of the spigot end as the spigot end is partially removed from the bell. The bell comprises a first end and a second end, the first end coupled to the first conduit. The bell has a concave annular inner surface and a diameter of the annular inner surface adjacent to the first end of the bell is greater than a diameter of the annular inner surface adjacent to the second end of the bell. The sealing device comprises a locking segment comprising a convex outer surface and a K-type gasket coupled to a locking segment or a non-restraining anti-extrusion segment. The sealing device is adapted to fit between the bell and the spigot. | 09-01-2011 |
| 20110072896 | PLASTIC WATER METER WITH METAL THREADS - Embodiments of the present invention generally relate to flow meters and more particularly to improved plastic water flow meters for commercial or residential use. In various embodiments, a plastic water meter is provided that may include metal threads for connecting the water meter to a water system. In particular, the plastic water meter may include at least one spud that is shaped to receive and engage a plastic spud insert, in which the plastic spud insert may include a metal ring with a threaded outer surface. The plastic spud insert may include an annular lip portion extending outwardly to discourage removal of the metal ring when the spud insert is engaged with the water meter. Furthermore, the plastic spud insert and the inner surface of the metal ring may have complementary circumferential profiles to discourage relative rotation between the metal ring and the spud insert. | 03-31-2011 |
