Abstract: A porous refractory in the K2O—SiO2—B2O3 system is formed by chemical direct foaming by heating to over 600° C., resulting in adherent black or white foam. The foam can function as highly porous thermal insulation, a high or low thermal emissivity surface, as a sealant for deteriorated refractory surfaces, as a filler for pockmarks/holes/gaps or as a bonding agent for parts with large gaps between them.

Abstract: A rotatable flanged component is adapted for assembly into a flow line of a high-pressure fluid transportation system. The rotatable flanged component comprises a body and a conduit. The body has at least two ends. The conduit extends between the ends. The rotatable component also has a flange and a union face at each of the ends. The flanges and union faces are adapted to provide a flange union between the component and other flowline components at each the body end. At least one of the flanges is a rotatable flange. The rotatable flange has a central opening and a plurality of holes. The holes are adapted to accommodate threaded connectors for loading the flange with an axial force. The flange is mounted on the body end through the central opening for rotation and for transmission of the axial force to the body end.

Abstract: Missiles for frac manifolds manifold the discharge from a plurality of pumps. The missile comprises a missile body and inlet assemblies. The missile body has a straight primary bore and a plurality of feed bores. The primary bore extends axially through the missile body. The feed bores extend radially through the missile body and define a socket. An inlet assembly is associated with each feed bore. The inlet assembly comprises a nipple and a collar. The nipple has a bore extending axially between a spigot and a union end. The nipple is connected to the collar. The spigot is received in the socket of the feed bore. The union end is adapted for connection to a flowline component. The collar comprises mating parts releasably coupled together around the missile body. The nipple is thereby releasably coupled to the missile body by coupling the collar to the missile body.

Abstract: A method and associated system for forming composite materials is presented, including providing a composite charge having applied release films to top and bottom surfaces and positioned on a contoured forming tool such that a portion of the composite charge over hangs a second upper surface of forming tool. A fairing bar abuts the forming tool that has an uppermost surface positioned above the second upper surface of the forming tool. The combination of the positioning of the failing bar and the use of release film in contact with the composite charge allows the composite charge to conform to the contoured forming tool without bridging or wrinkling the composite charge when a forming membrane and applied vacuum are used.

Abstract: Flowline components are assembled into high-pressure fluid transportation systems by a flange union. The flowline component comprises a body defining a substantially cylindrical central conduit. The conduit extends between first and second flat union faces and is adapted to conduct fluids through the body. The union faces are adapted to provide a mating surface for a flange union between the component and another flowline component. Accordingly, the union faces have a plurality of holes adapted to accommodate threaded connectors for forming the flange union. The holes are arranged in a defined array extending angularly around the conduit. Importantly, the array of holes on the first union face and the array of holes on the second union face are offset angularly relative to each other by an angle ?. It will be appreciated that such components may allow changes in the direction of a flow line.

Abstract: Pressure relief valves may be tapped into flow lines. The pressure relief valves are normally shut and are adapted to open at a threshold pressure in the flow line. The valves comprise a body which is adapted to allow the valve to be tapped into the flow line. A passage is defined in the body. The passage provides a valve inlet and a valve outlet. The inlet is in fluid communication with the flow line. A sacrificial closure is disposed in the passage and blocks flow through the passage. The closure is exposed to fluid pressure in the flow line. The valve also comprises means for compromising the sacrificial closure in response to detection of the threshold pressure in the flow line. The integrity of the closure will be compromised such that fluid from the flow line may flow through the passage and out the valve outlet.

Abstract: Methods of inducing tooth movement and treating malocclusion include reducing orthodontic treatment duration by daily applying cyclic forces simultaneously to teeth of the maxillary and mandibular arches during a treatment period. The teeth are also receiving static forces generated by an orthodontic appliance during the treatment period. The cyclic forces applied daily by clamping the teeth down on a bite plate, and activating an extraoral vibration source configured to deliver the cyclic forces to the bite plate at a constant frequency and a maximum force. Data indicating usage duration and usage frequency is stored electronically.

Abstract: A mattress having a foam core is provided. The foam core may include a channel along two or more sides of the foam core. Spring coils in the channel(s) provide increased localized support proximal the outer edge of the mattress. The spring coils may be conventional spring coils or individually pocketed spring coils. In certain alternatives, the spring coils may be replaced by foam different than the foam core; such difference may include foams having a higher indentation force deflection (IFD) rating. The mattress may have a foam core that is provided with an undercut filled with a foam insert where a higher IFD foam is provided in the undercut.

Abstract: Pressure relief valves may be tapped into high-pressure flow lines. The pressure relief valve is normally shut and is adapted to open at a threshold fluid pressure. It comprises a body, a passage, a valve seat, a ball, and a linear actuator. The passage is defined in the body and has a valve inlet and a valve outlet. The valve seat is in the passage. The ball is adapted to engage the valve seat to block flow through the passage. The linear actuator is mounted for linear movement in response to detection of the threshold pressure a from a normally extended position to a retracted position. In the extended position the ball engages the valve seat to close the passage, thereby shutting the valve. In the retracted position the ball can be flushed out of the valve by fluid flowing through the passage, thereby opening the valve.
