Title: Flow conditioner for a gas transport pipe
Inventor: DUTERTRE DOMINIQUE
IPC: F16L55/027
Filed: 1999-03-12
Granted: 2005-06-28
Abstract: The flow conditioner for a gas transport pipe comprises at least one perforated plate disposed essentially perpendicularly to the axis XX' of the pipe and comprising a central hole and sets of additional holes that are regularly distributed over at least three concentric rings centered on the axis of the pipe so as to define a perforated plate that is axially symmetrical.      Within any one ring all of the circular holes are of the same diameter d1, d2, d3. On going away from the central hole and on passing from any one ring to an adjacent concentric ring, the diameter of the holes changes alternately in a reduction direction and in an increase direction. Each ring has a number of holes that is equal to or greater than six. The perforated plate is advantageously associated with a porous plate situated upstream from the perforated plate and parallel thereto.

Abstract: A method of treating surfaces of a hydrogen absorbing alloy and, particularly, a method of treating surfaces of a hydrogen absorbing alloy by enhancing the resistance of the surfaces of the powder against contamination such as oxide film, moisture and adsorptive gases when the alloy powder is being treated in the open air. In pulverizing or in treating a powdery hydrogen absorbing alloy or in producing a powder by the quickly quenched coagulation, the hydrogen absorbing alloy is treated in an atmosphere containing an SF6 gas to form a protection film containing at least a sulfide or a fluoride on the surfaces of the hydrogen absorbing alloy in order to enhance resistance against contamination. The method comprises a step for containing the hydrogen absorbing alloy in a container to pulverize it by hydrogenation in a hydrogen atmosphere, a step for dehydrogenation by evacuating the container, and a step for heat-treating the hydrogen absorbing alloy in an atmosphere containing the SF6 gas in the container.

Abstract: An arbitration scheme for providing deterministic bandwidth and delay guarantees in an input-buffered crossbar switch with speedup S is presented.  Within the framework of a crossbar architecture having a plurality of input channels and output channels, the arbitration scheme determines the sequence of fixed-size packet (or cell) transmission between the input channels and output channels satisfying the constraint that only one cell can leave an input channel and enter an output channel per phase in such a way that the arbitration delay is bounded for each cell awaiting transmission at the input channel. If the fixed-sized packets result from fragmentation of variable size packets, the scheduling and arbitration scheme determines deterministic delay guarantees to the initial variable size packets (re-assembled at the output channel) as well.

Abstract: A method of determining whether a page to be printed on a color printer will actually be entirely printed in one colorant, usually black, and if so, automatically omitting whatever processing steps are unnecessary as a result. Determining if the page is monochrome can be done either by (1) including a signal in the PDL or by a signal from the user or by (2) inspecting each element of the page to determine if all elements are specified to be printed in the same one colorant. If either is true, then various color operations such as trapping, color conversion to any other color, and color correction for non-selected colors can be automatically omitted.

Abstract: The hydraulic control system for operating a flow tube in a subsurface safety valve is disclosed. An isolation piston is used in conjunction with an operating control line and an engagement control line. Both control lines run from the surface. The isolation piston is spring loaded to equalize pressure across a dynamic piston to allow the flow tube to be shifted by a power spring to allow in turn the subsurface safety valve to close.  Application of pressure on the engagement control line directs pressure applied through the operating control line to the top of the dynamic piston thus shifting the flow tube downwardly to open the subsurface safety valve. In an alternative embodiment, a coaxial control line directs fluid to the top of the dynamic piston and additionally to a parallel path leading to the bottom of the dynamic piston where a control valve is mounted. The control valve can be actuated hydraulically, electronically or other ways such that when it is closed the pressure applied to the dynamic piston shifts the flow to open the subsurface safety valve. A loss of signal to the control valve equalizes the dynamic piston allowing the flow tube to shift.
