Patent number: 7021328Abstract: A method of replacing a gas main that supplies gas to a recipient through an existing service line includes connecting a first tapping tee to the new gas main and connecting a second tapping tee to the existing service line that communicates with a downstream recipient. Branch passages of the first and second tapping tees are fluidically connected together by a connecting conduit. The new gas main is then tapped with the first tee so that gas flows from the new gas main into the connecting conduit up to the second tee. All air is bled from the connecting conduit between the first and second tees, and the existing service line is then tapped with the second tee so that gas is supplied to the recipient through both the existing service line and the connecting conduit. Gas flow to the recipient from the old main is then terminated. The second tee is a specially configured tapping tee specifically adapted for bleeding air from the connecting conduit that interconnects the first and second tees.Type: GrantFiled: August 15, 2003Date of Patent: April 4, 2006Assignee: Keyspan CorporationInventors: David L. Robison, Gregory Alan Brzozowski, Mario Carbone

Patent number: 6138501Abstract: A plunger apparatus is presently disclosed that includes a housing, and a probe slidably supported by the housing. A damping assembly is supported by the housing and cooperating with the probe. The housing, preferably, has a proximal portion and a distal portion wherein the probe is slidably mounted within the housing and extending axially from the distal portion. The probe, desirably, has an increased diameter portion at a proximal end thereof and a penetrating tip adjacent a distal end thereof. A hammer mechanism is provided that is slidably supported by the housing and cooperatively engaging the probe and cooperating with the damping assembly. The housing may also include a handle assembly. A method for using the plunger apparatus is also disclosed.Type: GrantFiled: October 16, 1998Date of Patent: October 31, 2000Assignee: KeySpan CorporationInventor: Jahangir Rastegar
