摘要： A packing assembly for a valve includes a first segment having at least one first guiding surface, and a second segment having at least one second guiding surface in engagement with at least a portion of the at least one first guiding surface. A shape-memory member couples the first and second segments. The shape-memory member may be formed of a material that is responsive to changes in temperature, so that, in response to a change in temperature, the shape-memory member may cause relative movement of the first and second segments in a first direction. In response to the movement, the first and second guiding surfaces may cause relative displacement of the first and second segments in a second direction.

摘要： An apparatus for use in making localized passive measurements of electromagnetic radiation emitted from an object located in a radioactive environment includes a hollow elongate conduit having a first end, a second end, and a reflective inner surface. The first end of the conduit is positionable in the radioactive environment proximate the object, and the second end of the conduit is positionable outside the radioactive environment. The conduit has at least one bend between the first end and the second end, such that light entering the first end of the conduit is reflected by the inner surface of the conduit at least once as it travels through the conduit before reaching the second end. A detector in optical communication with the second end of the conduit is configured to detect electromagnetic radiation that reaches the second end.

摘要： A cross-over fluid coupling includes a first coupling end and a second coupling end. A plurality of first conduits have inner ends disposed toward the first coupling end and outer ends spaced apart from the inner end toward the second coupling end and being outboard of the inner end. A plurality of second conduits have outer ends that are disposed toward the first coupling end and positioned laterally outboard of the inner end of at least one of the first conduits, and inner ends that are spaced apart from the outer end toward the second coupling end in the axial direction and is laterally inboard of the outer end of the at least one of the first conduits.
