Title: Measurement of a gas characteristic
Inventor: HAMMOND PAUL STEPHEN
IPC: G01N33/22
Filed: 1995-11-22
Granted: 1999-08-10
Abstract: Apparatus to measure the calorific value and/or Wobbe index of a fuel gas supplied along a pipe. A control can operate first and second outlet valves and can cause an inlet valve to be locked in a closed position or unlock it to allow it to open which it normally is until the gas pressure in a chamber, of predetermined volume, reaches a predetermined pressure difference above the pressure in the pipe. Under direction of the control, a pump pumps fuel gas from the pipe into the chamber whilst the outlet valves are closed.      On the pressure in the chamber attaining the predetermined difference above that in the pipe, the inlet valve closes automatically and is then held locked closed by the control. Now the values of certain properties of the gas in the chamber are measured and corrected to standard temperature and pressure. Those properties can be the speed of sound in the gas, and/or the thermal conductivity, and/or specific heat capacity. Then the first outlet valve is opened and the gas from the chamber discharges back to the pipe through an orifice plate.     and conduits. This allows the control to measure the value of the property of density of the gas corrected to standard temperature and pressure.      The first outlet valve 32 is closed again and the inlet valve is unlocked so it opens automatically.  The pump pumps another sample of gas into the chamber until the gas pressure therein attains the predetermined value above the pressure in the pipe and the inlet valve again closes automatically and is then again locked in the closed position. Now the second outlet valve is opened to allow the gas from the chamber to discharge to the pipe through a capillary passage. This discharge allows the control to measure the value of the property of the viscosity of the gas at standard temperature and pressure. Stored in the control are sets of prederived values of the different properties each set correlated to a particular calorific value and/or Wobbe index of the gas. The control compares the measured values with those in the sets to establish which set has values nearest to the measured ones and thereby the control infers the calorific value and/or Wobbe index of the gas in the pipe.

Title: Method of incorporating drugs into a polymer component of stents
Inventor: EURY ROBERT P
IPC: A61F2/82
Filed: 1996-03-20
Granted: 2001-06-19
Abstract: The drug-loaded polymeric material containing a therapeutic drug can be applied to a structure of an intravascular stent.  A therapeutically effective amount of a therapeutic drug is incorporated into such a layer of polymeric material, without significantly increasing the thickness of the stent, to avoid interfering with the function of the stent.  The drug-loaded polymer coating of the stent can formed to include pores, can be multi-layered to permit the combination of a plurality of different drug containing materials in a single stent, and can include a rate controlling membrane to allow for controlled retention and delivery of selected drugs within the affected blood vessel upon implantation.  The layer of polymeric material is manufactured by combining the selected polymeric material with a relatively high loading of the therapeutic drug in a thermal process, such as coextrusion of the therapeutic drug with the polymeric material.  The therapeutic drug is dispersed and incorporated into the polymer as small particles, preferably having a maximum cross-sectional dimension of 10 microns.

Abstract: An improved method of separating bound labeled indicator from free labeled indicator in a layer of a test element for immunoassay, comprising a) depositing sample containing a target immunoanalyte onto an exterior surface of a test element in the presence of the labeled indicator, and b) adding wash liquid to the exterior surface by i) depositing a first amount of wash liquid at a first location on the surface in a pool, ii) allowing a portion of the pool to spread out through a first portion of the test element to wash out free labeled indicator, and iii) depositing a second amount of wash liquid at a second location on the surface, to spread out through a second portion of the test element, so that background signal due to non-separated free labeled indicator remaining in the volume is reduced.

Abstract: A production logging tool is provided for use within a well to directly measure a velocity profile of a multiphase fluid flow within a cross-section of a well. The production logging tool includes a tool housing from which a plurality of arms are radially extensible. The plurality of arms are rotatably mounted to the tool housing for rotating around a tool axis extending longitudinally through the tool housing. At least one Doppler flow sensor is fixedly mounted to one of the plurality of arms for moving with the arm to dispose the Doppler flow sensor within different localized regions within a cross-section of the well.      The localized regions of the cross-section are located at different radial distances from and at different angular displacements around the tool axis of the tool housing, at points distal from the tool axis. The Doppler flow sensor has a depth of investigation for detecting flow velocities of a multiphase fluid flow proximate to the Doppler flow sensor, within the localized regions of the cross-section of the well. The plurality of arms are rotated about the tool housing to dispose the Doppler flow sensor within different ones of the localized regions disposed throughout the cross-section for measuring a velocity profile of the multiphase fluid flow through the cross-section of the well. Flow velocities are also preferably detected within localized regions disposed within the boundary layer of the multiphase fluid flow.

Abstract: In an ignition assembly for a flare vent having an open terminal end for ventingwaste gases, a hollow tubular stripper is located ad jacent a generally upright exterior wall of the flare vent and has a lower opening and an upper opening proximate to the terminal end of the flare vent. A conduit for diverting some of the waste gases from the flare vent to the stripper is located below both the upper opening of the stripper and the terminal end of the flare vent. A pilot has an ignition end to ignite the diverted waste gases in the stripper to produce an ignition flame at the upper opening of the stripper, which in turn ignites the waste gases exiting the terminal end of the flare vent. The pilot is housed in a sleeve having an open first end for receiving the pilot and an open second end for exposing the ignition end of the pilot to the waste gases in the stripper. The sleeve is insertable into the stripper and, when inserted, allows air flow through the stripper to produce the ignition flame and to cool the sleeve. A track is attached to the exterior wall of the flare vent for moving the sleeve and pilot between an inoperative position near the base of the flare vent and an operative position near the terminal end of the flare vent. In the operative position the second end of the sleeve and the pilot are located within the stripper below the stream of waste gas entering the stripper through the conduit.

Abstract: The present invention is method, rate controller, and system for preventing over-flow and underflow of a decoder buffer in a video compression system. First, a plurality of quantized video bits is received from an encoder (102). The plurality of quantized video bits correspond to a video frame type. Then, a virtual buffer is created, in a rate controller, to model fullness of a decoder buffer, based on the quantized video bits, to produce a virtual buffer fullness (104). A quantization stepsize estimate is finally determined, in a rate controller, based on at least a first predetermined target bit al-location the video frame type, and the vir-tual buffer fullness (106). The quantization stepsize estimate will prevent the overflow and underflow of a decoder buffer.
