IPC: E21B43/40
Filed: 2008-02-21
Abstract: A method for recovering heavy oil including recovering an oil-water mixture from a well and separating oil from the oil-water mixture to produce an oil product and produced water. The produced water is separated into a series of produced water streams. Each produced water stream is directed into each of a plurality of interconnected evaporators in a multiple effect evaporator. A first produced water stream is heated and vaporized to form a first vapor stream. The first vapor stream then heats and vaporizes a second produced water stream to form a second vapor stream. This process may continue wherein the second vapor stream heats and vaporizes a third produced water stream. The vapor streams are condensed to form a distillate that is directed to a steam generator. The steam generator then heats the distillate and produces steam to inject into an oil injection well.

Title: Dense phase distribution branch
Inventor: MEMORY RUSSELL JAMES
IPC: A01C15/00
Filed: 2009-09-22
Abstract: A branch for distributing granular material includes an inlet portion, a transition portion downstream of the inlet portion, and an outlet portion downstream of the transition portion. Each portion has a critical air flow rate that is required to cause the granular material to flow through the respective portion. The branching that occurs at the transition portion results in the critical air flow rate of the transition portion being greater than the critical air flow rate of the inlet portion, typically requiring an amount of air at least equal to the critical air flow rate of the transition portion to flow granular material through the branch. In the disclosed branch, the inlet portion is oriented relative to the outlet portion such that applying air to substantially equal the critical air flow rate of the inlet portion results in granular material being urged by gravity to move through the transition portion and into the outlet portion.

Title: System and method for characterizing a sample by low-frequency spectra
Inventor: BUTTERS LISA C
IPC: G01N27/72
Filed: 2003-03-28
Abstract: A method and apparatus for interrogating a sample that exhibits molecular rotation are disclosed. In practicing the method, the sample is placed in a container having both magnetic and electromagnetic shielding, and Gaussian noise is injected into the sample. An electromagnetic time-domain signal composed of sample source radiation superimposed on the injected Gaussian noise is detected, and this signal is cross-correlated with a second time-domain signal produced by the same or similar sample, to produce a cross-correlated signal with frequency domain components. The latter is plotted in the frequency domain by a fast Fourier transform to produce a frequency domain spectrum in a frequency range within DC to 50KHz. From this spectrum, one or more low frequency signal components that are characteristic of the sample being interrogated are identified.

Title: Guide tube for continuous rod
Inventor: BASLER HERMANN
IPC: F16L7/00
Filed: 2009-11-19
Abstract: A guide tube for continuous rod has a sections pivotably connected together by at least one translatable pivot. The tube connects to a rig at a fixed pivot and is initially folded on the rig for transport. To unfold and raise the tube for operation, a rig operator pivots a support rod pivotably connected to the tube away from the rig using a rope. This pivoting support rod moves the attachment point of a winchline extending from the rig to the rod beyond the tube's fixed pivot. Also, the pivoting rod tensions a sling having a fixed length that extends from the rod to the tube's translatable pivot. In this way, the winchline can be tensioned without the need for rig operators to perform a substantial amount of manual labor as conventionally done. Once the outer sections of the guide tube are lowered to the ground, the entire guide tube can be unfolded and raised with the tensioned winchline.

Title: Adaptive coefficient scanning in video coding
Inventor: KARCZEWICZ MARTA
IPC: H04N19/593
Filed: 2008-06-12
Abstract: This disclosure describes techniques for scanning coefficients of video blocks, e.g., quantized and transformed coefficients. Rather than use conventional zig-zag scanning, the techniques of this disclosure adapt the scanning order based on statistics associated with previously coded blocks that were coded in the same prediction mode. For each prediction mode, statistics of the coefficients are stored, e.g., indicating probabilities that given coefficients are zero or non-zero. Periodically, adjustments to the scanning order can be made in order to better ensure that non-zero coefficients are grouped together and zero value coefficients are grouped together, which can improve the effectiveness of entropy coding. The techniques of this disclosure provide thresholds and threshold adjustments that can reduce the frequency that the scanning order adjustments occur, yet still achieve desired improvements in compression due to such scanning order adjustments.

Inventor: UTKHEDE DEEPANK
IPC: A61M5/14
Filed: 2008-09-05
Abstract: A solid drug core insert can be manufactured by injecting a liquid mixture comprising a therapeutic agent and a matrix precursor into a sheath body. The injection can be conducted at subambient temperatures. The mixture is cured to form a solid drug-matrix core. The therapeutic agent can be a liquid at about room temperature that forms a dispersion of droplets in the matrix material. A surface of the solid drug core is exposed, for example by cutting the tube, and the exposed surface of the solid drug core releases therapeutic quantities of the therapeutic agent when implanted into the patient. In some embodiments, the insert body inhibits release of the therapeutic agent, for example with a material substantially impermeable to the therapeutic agent, such that the therapeutic quantities are released through the exposed surface, thereby avoiding release of the therapeutic agent to non-target tissues.
