Abstract: A method for re-tensioning a stressed tendon cast in a reinforced concrete structure includes removing concrete from the structure to expose the tendon. A pocket former is attached to the exposed tendon. The pocket former comprises two partial sections assembled to enclose the tendon. Grout is poured around the pocket former and is allowed to substantially cure. The pocket former is removed and the tendon is cut. An anchor is assembled to the tendon and the tendon is stressed.

Abstract: A method for retaining tension in a stressed tendon cast in a reinforced concrete structure includes removing concrete from the structure to expose the tendon, attaching a re-anchoring clamp to the exposed tendon, the re-anchoring clamp comprising two partial sections assembled to enclose the tendon, pouring grout around the re-anchoring clamp and allowing the grout to substantially cure.

Abstract: An exhaust treatment device includes first and second substrates positioned in parallel within a housing. A baffle plate supports the substrates, an inlet tube and an outlet pipe, and defines a portion of a first chamber. First ends of the substrates and a second end of the inlet tube is in fluid communication with the first chamber. A partition supports the substrates, the inlet tube and the outlet pipe and defines a portion of a second chamber separate from first chamber. Second ends of the substrates and a second open end of the outlet pipe is in fluid communication with the second chamber. All of the exhaust flows in a first direction through the inlet tube, reverses direction through the substrates and reverses direction again to flow through the outlet pipe.

Abstract: An exhaust treatment system includes first and second exhaust conduits positioned on opposite ends of an exhaust treatment device. The exhaust treatment device includes a housing having a first outer diameter at a first end and a different second outer diameter at a second end. A clamp includes an inner surface engaging both the first exhaust conduit and the exhaust treatment device when the exhaust treatment device is positioned with its first end adjacent to the first exhaust conduit. The inner surface of the clamp is spaced apart from one of the housing and the exhaust treatment device when the second end of the exhaust treatment device is adjacent the first exhaust conduit.

Abstract: An exhaust treatment component for treating an engine exhaust including a housing including an inlet and an outlet. A mixing device is located within the housing between the inlet and the outlet, and the mixing device includes a shell communicating with the outlet, a decomposition tube having a first end and a second end, and a flow reversing device disposed proximate the second end. The first end extends from the shell and is configured to receive the exhaust from the inlet, and is configured to receive a reagent exhaust treatment fluid. The second end is positioned within the shell. The flow reversing device is configured to direct a mixture of the exhaust and reagent exhaust treatment fluid in predetermined directions into the shell, the flow reversing device reverses a flow direction of the exhaust back towards the first end of the decomposition tube.

Abstract: An exhaust treatment system includes an exhaust treatment device having a stepped outer diameter. First and second clamps each include a stepped inner diameter such that the clamps engage the exhaust treatment device and other portions of the exhaust treatment system when the exhaust treatment device is properly oriented. The exhaust treatment device interferes with one of the clamps to preclude coupling the exhaust treatment device to an adjacent portion of the exhaust treatment system when an attempt is made to install the exhaust treatment device in a reversed improper orientation. A consistent exhaust flow direction through an exhaust treatment device such as a diesel particulate filter may be maintained through use of the inventive system.

Abstract: An exhaust treatment system includes an emissions treatment device for treating exhaust emitted from an internal combustion engine. The exhaust treatment system includes a frame adapted to support first and second spaced apart portions of the exhaust treatment system. The emissions treatment device interconnects the first and second portions and is in receipt of exhaust from the first portion and provides treated exhaust to the second portion. A first bracket is fixed to the frame and includes one of a protrusion and a receptacle. A second bracket is adapted to be fixed to the emissions treatment device and includes the other of the protrusion and the receptacle. The protrusion is positioned within the receptacle when the emissions treatment device is properly positioned. The protrusion interferes with one of the second bracket and the emissions treatment device to preclude assembly when the emissions treatment device is improperly positioned.
