Abstract: A joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, helium vent gas and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface. A weld-free MRI machine quench vent discharge system using pre-fabricated chimney duct components may be configured by selecting a quench vent outlet and discharge location, mapping a route, and determining directional changes. Elbows and bellows sections are selected based on these changes, and the distance between the MRI machine and discharge location is calculated to determine support positions. The system is assembled using prefabricated chimney ducts, each comprising an inner shell with spinner bolt flanges and a leak-free joint with a PTFE gasket. The design includes an outer shell with an insulation gap for thermal protection.

Abstract: A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

Abstract: A chimney section and a chimney system for handling gases is disclosed. The chimney section is rounded but non-circular in cross sectional shape and includes at least one flange on one end of the section body. The chimney section may be formed from a single piece of material, wherein the section body and flange are integrally formed with one another. In the chimney system, the junction between two adjacent chimney sections may consist of a flange interface, which is formed by the adjacent flanges on opposing ends of two adjacent chimney sections. A V-band may be placed over the flange interface to further seal the interior of the chimney sections, and a sealant may be placed in various positions of the chimney system to hermetically seal the interior thereof from the exterior. In another embodiment of the chimney system, insulation is added to create an insulated chimney system.

Abstract: A method and apparatus for a conveyor tensioning system comprising a main frame with at least one main frame roller pivotally mounted thereto for engagement with a conveyor belt. A moveable frame is engaged with the main frame at an engagement interface such that the position of the moveable frame with respect to the main frame may be adjusted in at least one dimension. The moveable frame also includes at least one moveable frame roller pivotally mounted thereto for engagement with a conveyor belt. The position of the moveable frame with respect to the main frame may be actuated by hydraulic cylinders or other mechanical systems. As the distance between the main frame and moveable frame increases, the tension on the belt also increases.
