  • Patent number: 9814866
    Abstract: A flushable valve which has unidirectional flushing can be used to flush a lumen of a stent, catheter and/or tubing. By flushing the stent, catheter and/or tubing, particulates or residue that can block or impede the flow of fluid out of the stent, catheter and/or tubing can be overcome thereby facilitating continued drainage. An automatic flushable valve eliminates manual manipulation of the device. In an embodiment of the invention, a back pressure sensor can be used to detect when the flow through the stent, catheter and/or tubing has become impeded and activates a flushing cycle. In an embodiment of the invention, a leak detector can be used to detect when an operation has caused the flush device to leak. In various embodiments of the invention, the back pressure sensor and the leak detector can be used to detect that the flush device is operating under normal conditions.

    Abstract: An apparatus for controlling hydrocarbon delivery in an exhaust gas processing system of an engine that includes a heat generating device and a DPF, comprising a fuel injector and a control manifold, which has a pressure chamber holding compressed air for separating hydrocarbon from exhaust gas, and is fluidly connected to the fuel injector, a fuel control solenoid valve for controlling hydrocarbon supply, a pressure sensor, and a volume changing device, which provides a linear relationship between its volume change and pressure change in the control manifold. With the volume changing device, a deterioration factor value indicative of performance change of the hydrocarbon delivery device can be calculated for compensating temperature control, calculating the hydrocarbon conversion efficiencies of the heat generating device and the DPF in the exhaust gas processing system, detecting failures and mal-functions in the exhaust gas processing system and the engine.

  • Publication number: 20140052101
    Abstract: A valve is provided for controlling flow along a fluid line that includes an outer shell and an inner housing slidably disposed therein that includes connector threads surrounding a boss on one end and a passage through the boss. A backing member is coupled to the outer shell and has a sealing pin extending into the passage. The inner housing is movable helically relative to the outer shell from a closed position wherein a sealing pin engages an outlet opening at the distal end of the boss to seal the opening and an open position in which the inner housing is directed away from the sealing pin to open a fluid path through the valve. A torque limiter mechanism between the outer shell and inner housing resists movement from the valve closed position to the valve open position until a selected torque level is reached.

  • Patent number: 8608823
    Abstract: The invention relates to an apparatus and a process for granulating a metal melt. The apparatus substantially comprises a round water tank, into which water is injected in a tangential direction with the aid of a number of nozzles, so that the water in the tank rotates and forms a parabolic surface. The nozzles are arranged such that they are distributed in height and around the circumference of the tank wall. The uppermost nozzle is located in the region of the surface of the water and produces a stream of water or fan of water lying in the surface of the water. For granulating a metal melt, it is poured continuously from a melting crucible into the stream of water or fan of water of the uppermost nozzle.

  • Patent number: 8590555
    Abstract: The present invention presents various novel approaches to solving the problems inherent in measuring biological pressures in high pressure systems. Thus, to protect a pressure transducer exposed to fluid flows at higher pressures than its overpressure rating, a novel valve is used that closes a protected leg in which the transducer is located. The various exemplary embodiments of such valves each have a high pressure input, one or more low pressure inputs, and an output. In operation, when a high pressure fluid flow occurs at a high pressure input, such valves automatically close the low pressure inputs. Alternatively, a novel transducer system is presented, which automatically limits the effective pressure sensed by a transducer to a certain maximum.

    Abstract: An injection device for administering a reagent into an exhaust passage of an internal combustion engine, the injection device having an axis along its length and comprising an outwardly opening valve member having a seating surface which is engageable with a valve seating region. A seating member provided with an internal bore which defines the valve seating region, wherein the internal bore further defines a flow re-directing region downstream of the valve seating region. The seating member has an end face provided with a feature which intersects with at least a portion of the flow re-directing region to define, together with the flow re-directing region, a spray path for reagent exiting the injection device when the valve member is moved outwardly from the bore away from the valve seating region. The spray path has a variable spray angle, relative to the axis, around the circumference of the valve seating region.

  • Publication number: 20130213479
    Abstract: A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

  • Patent number: 8475550
    Abstract: A method for injecting a chemical, such as an odorant, from a chemical supply into a fluid-containing system such as a natural gas or an LPG pipeline. A tank of odorant is maintained at a pressure above ambient, but below pipeline pressure. An injection conduit communicates the odorant tank with the pipeline. A hydraulic pressure booster is located in the injection conduit for pressurizing the chemical to a pressure above that of the pipeline. Flow-control apparatus located within the injection conduit for metering chemical to be injected into the pipeline is either (a) drip-style metering valve adjustable between a drop-wise setting and a steady-flow setting or (b) a pair of valves one of which is a flow valve allowing larger volumes to be injected and the other which is a drop-wise flow valve for metering smaller volumes of the chemical.
