Abstract: The invention provides a method of, and means for, connecting components of a moveable sub-assembly in a fluid control valve. To control a dimensional characteristic of the moveable sub-assembly, a first component of the sub-assembly can be crimped to create a mechanical connection to a second component of the moveable sub-assembly. The sub-components may be configured such that in the absence of the crimp they can be moveably translated between a plurality of positions and they may be slideably translatable between a number of relative positions, while the crimp acts, once formed, to retain the sub-components in a chosen position relative to one another.
Abstract: A dispensing system for delivery of a dispersant from a canister containing an erodible but cakeable water dispersant wherein the cakeable water dispersant in a one piece caked condition falls to a bottom of a divergent walled canister so the water flowing through a bottom portion of the canister continues to maintain erodible contact with the dispersant as the water disperant is consumed.

Abstract: The pressure-type flow controller includes a main body provided with a fluid passage, a control valve for pressure control fixed in a horizontal position to the main body, an on/off valve fixed in a vertical position to the main body on the downstream side of the control valve for pressure control, an orifice provided in the fluid passage on the upstream side of the on/off valve, and a pressure sensor fixed to the main body for detecting the internal pressure of the fluid passage between the control valve for pressure control and the orifice. The fluid passage includes a first passage portion in a horizontal position connected to the control valve for pressure control, a second passage portion in a vertical position connecting the first passage portion to the orifice, and a third passage portion in a horizontal position connecting the second passage portion to the pressure sensor.
Abstract: A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.
Abstract: A method for pipe coupling encapsulation includes placing two elastomeric partial rings around pipes on opposite sides of a leaking joint coupling, taking a repair coupling, which includes a band and opposing clamp members extending outwards from ends of the band, and placing the band around the leaking joint coupling such that opposite end portions of the band overlie the elastomeric partial rings, and tightening the opposing clamp members towards each other with one or more tightening elements.
Abstract: A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle.

Abstract: Embodiments of a valve assembly and a plumbing system incorporating the same are provided herein. In some embodiments, a valve assembly for use with an enclosed environment includes a housing having an interior volume, an inlet disposed at a first end of the housing and fluidly coupled to an environment surrounding the housing, and an outlet disposed at a second end of the housing opposite the first end and fluidly coupled to the enclosed environment; a first valve having a first valve seat and a first sealing member at least partially extending through a first opening in the first valve seat in a closed position; and a second valve disposed beneath the first valve and having a second valve seat and a second sealing member at least partially extending through a second opening in the second valve seat in a closed position.
Abstract: A release mechanism includes a frame with an interior. The release mechanism also includes a prestrained element coupled to the interior of the frame. The prestrained element creates a seal with the frame. The prestrained element is notched in one or more regions. The prestrained element is configured to fracture when heated to a predetermined temperature allowing the interior to open. The fracture is based on the notched regions of the prestrained element such that separation initiates within the notched regions. The remaining regions of the prestrained element unfractured. The shape memory alloy element can include one or more of a nickel-titanium alloy, a titanium-nickel alloy, a copper-zinc-aluminum alloy, a copper aluminum nickel alloy, and a nickel titanium hafnium alloy. Heating of the shape memory alloy element causes a stress in the shape memory alloy that causes fracturing of the prestrained alloy when sufficient heating has been achieved.
Abstract: Rotary valve assemblies are disclosed, for example, for use in a thermal management system. The assembly may include a first rotary valve including a primary shaft including a hollow portion defining a first inner cavity and a first spline piece disposed within the first inner cavity on one end and including a primary spline feature on an opposite end, the primary spline feature having one or more primary splines. A second rotary valve may include a secondary shaft including a hollow portion defining a second inner cavity and a second spline piece disposed within the second inner cavity and including a secondary spline feature having one or more secondary splines. One or both of the first spline piece and the second spline piece may be formed of metal. The primary splines and the secondary splines may be configured to mesh together to form a spline joint between the rotary valves.
Abstract: Valve assemblies with butterfly valves for use as a double isolation & bleed (DIB) valve and a double block & bleed (DBB) valve. The embodiments may have a twin-disc design with a non-separable, valve body having a central bore. A pair of butterfly valves may reside in the central bore, each having an annular seal and a rotatable disc that contacts the annular seal to prevent flow of fluid into space between the butterfly valves. Implementations of the embodiments configure the annular seal with a sloped contact surface at an angle to positively seal the rotatable discs in the preferred direction of incoming flow. In this way, the valves can always close in response to either uni-directional flow into one end of the central bore or bi-directional flow into both ends of the central bore, respectively or simultaneously.
Abstract: A flexible check valve for fluid-handling systems that prevents reverse flow but allows downstream flow of fluid comprises a dome that fits within a pipe and includes a concave surface. The flexible check valve further includes a flexible seat that fits within the pipe and includes a. convex surface. The flexible seat is deformable from a closed position, that prevents reverse flow, to an open position, that allows downstream flow, when an upstream pressure acts on the flexible seat and exceeds a downstream pressure and when, in the closed position, the concave surface of the dome is oriented downstream and the convex surface of the flexible seat is oriented upstream. A housing is connected to the dome and the flexible seat and is connectable to the pipe. A seal is formed between the concave surface and the convex surface when the flexible check valve is in the closed position.
Abstract: A valved tap is disclosed comprising a tap body having a through bore from a threaded input end to an output end thereof. A globe valve is positioned in the valve body so as to interrupt the flow of fluid in the through bore. The output end of the tap body may comprise a flanged portion connectable to a manifold.
