Abstract: An arcuate member is clamped onto a pipe so that a protrusion or ridge penetratingly engages the outside surface of the pipe.

Abstract: An apparatus and method according to which a piece part is inspected and sorted. In several exemplary embodiments, the piece part is a post-tension concrete anchor. In an exemplary embodiment, the apparatus includes a reference component configured to engage the piece part by extending within an opening defined the piece part. The reference component extends within the opening by a first distance, the first distance being based on at least one dimension defined by the opening. A depth measurement device is configured to measure a second distance, which is a function of the first distance. A controller is configured to determine whether the second distance is within a predetermined range. If not, a bracket disengages the piece part from the reference component at a first location. If the second distance is within the predetermined range, the bracket disengages the piece part from the reference component at a second location.

Abstract: An apparatus and method according to which a piece part is inspected and sorted using a depth measurement device. In several exemplary embodiments, the piece part is a post-tension concrete anchor.

Abstract: An access door according to which the access door is hingedly or pivotally coupled to a panel such as, for example, a water meter box cover or another type of meter box cover.

Abstract: An apparatus according to which the apparatus includes a pair of connected arcuate members for clamping around a pipe, with each arcuate member including at least one protrusion. The arcuate members have a first material hardness and at least a portion of the at least one protrusion has a second material hardness that is greater than the first material hardness so that the portion penetratingly engages the pipe when the arcuate members are clamped around the pipe.

Abstract: A restrained sleeve coupling assembly for interconnecting pipe sections includes a generally cylindrical sleeve body, a generally cylindrical adaptor body and opposed end rings which are sleeved over the respective pipe sections to be joined. The generally cylindrical sleeve body has opposed gasket engaging surfaces adjacent opposite ends of the sleeve body for receiving fluid sealing gaskets forcibly engaged with the sleeve body, the adaptor body and one of the opposed end rings. The adaptor body includes a gasket engaging surface for receiving a fluid sealing gasket forcibly engaged with the adaptor body and the other of the opposed end rings. The end rings include flanges for engagement with elongated tension bolt assemblies to secure the sleeve body, the adaptor body, the gaskets and the end rings in assembly with each other.

The end rings include flanges for engagement with elongated tension bolt assemblies to secure the sleeve body, the gaskets and the end rings in assembly with each other. The end rings also include circumferentially spaced bosses and polygonal shaped gripper members disposed in recesses in the bosses and forcibly engageable with the outer surfaces of the pipe sections over which the end rings are sleeved as determined by limited torque bolt assemblies engageable with the gripper members.

Abstract: A hinge connection between an access door and a panel, such as a utility meter box cover, is formed by opposed cylindrical hinge pins which are integrally cast as part of the access door, and spaced-apart channel-shaped recesses formed in bosses which are cast as part of the panel facing a side of the panel opposite a planar wall part of the panel, which wall part includes an opening for receiving the access door. The hinge pins are supported in the channel-shaped recesses and are retained therein by conventional hex head machine bolt and nut assemblies which project through respective bores in the panel or meter box cover and intersect the channel-shaped recesses. The bolt heads are disposed in elongated slots opening to the planar surface of the panel or meter box cover and having widths only slightly greater than the distance across the flats of the bolt heads, respectively.

Abstract: A joint restraint (10) for securing a first pipe (12) to a second pipe. The joint restraint (10) includes an annular body (14) and a plurality of wedge housings (18) extending from the annular body (14) and characterized by open rear faces (38) to allow coreless casting. A bolt (32) is disposed within a hole (30) in each wedge housing (18) and a wedge (40) is disposed within each wedge housing (18). Each wedge (40) has a bolt-actuated tooth (52), a larger pressure-actuated tooth (54), a top surface (44) having a groove (48) adapted to slidably receive a bolt actuator (32), and a bottom surface (42) that is partially tapered to act as a bearing (76) limiting the extent of bolt-driven actuation.
