Patent CA-2162741-A1 (CA)
Title: Single horizontal wellbore gravity drainage assisted steam flood process and apparatus
Inventor: NZEKWU BEN IFEANYI
IPC: E21B43/24
Filed: 1995-11-14
Abstract: Heavy oil may exist as unconsolidated deposits in thin zones, sometimes underlain by bottom water, which deposits flow under solution-gas drive primary recovery mechanisms, resulting in rapid reduction in reservoir pressure and recovery of quantities of sand with oil.      A gravity-drainage assisted steam flooding process for recovery from thin viscous reservoirs uses a single horizontal wellbore. Steam is injected through tubing penetrating the reservoir to condition and heat the wellbore producing oil and reservoir fluids. After a period of steam circulation, production is constrained and steam injection is continued to initiate an active steam chamber. Fluid withdrawal is resumed while pressure is maintained. Steam injection is continued to cause the expansion and propagation of the active steam heated volume. As steam flows into the reservoir under gravitational counter current flow and pressure drive, heated oil, steam condensate and reservoir fluids drain and are pumped to the surface.

Title: Apparatus and method for determining geostrophic wind velocity
Inventor: WIESE CHUCK F
IPC: G01P5/14
Filed: 1994-08-22
Abstract: A geostrophic winds forecasting method (10) determines an atmospheric density (D) (14) and a Coriolis parameter (F) (16) at a given location. The atmospheric pressure is detected N times (20) at the location over a predetermined period of time (t). The period of time (t), e.g., two hours, corresponds to the time required for a pressure surface to travel a distance (x) at an empirically determined velocity, e.g., 35 knots. The change in pressure (.DELTA.P) is detected over a period of time (t). The geostrophic wind velocity (VG) is then determined (22), according to the invention, based on the following relationship: VG = [1/(D x F)] x [.DELTA.P/X]. The resulting geostrophic wind velocity (VG) is then displayed (25). At 35 knots, over a given two hour period, the distance X traveled by the pressure surface is approximately equal to 129,640 meters. The method is embodied in a weather instrument comprising a conventional barometer to produce a weather forecasting station.

Abstract: A plurality of ATM networks may be interconnected to allow communication of voice-band signals between them by using one or more PSTNs and a novel interface that converts ATM formatted data packets to a format usable by digital multiplicationequipment (DCME). Such an interface thus allows the DCME to advantageously function as a gateway between the ATM network and PSTN by providing for optimum bandwidthusage between the networks. In an illustrative example of the invention, a DCME available from AT&T as the Integrated Access and Cross Connect System ("IACS"), is provided with an ATM-to-DCME interface that converts ATM formatted packets to a regular channelized bitstream usable as an input by the IACS. The interface and the IACS are positioned on both ends of a PSTN to allow for connectivity between the PSTN and a plurality of ATM networks, as well as the required optimization of bandwidth usage. In another illustrative example of the invention, the functionality of the interface is built in to the IACS to convert ATM formatted packets directly into efficient wideband formatted packets for transmission over the PSTN.

Filed: 1996-07-23
Abstract: The present invention is a process for hydrophobically modified emulsion polymers, polymers obtained thereby, waterborne coating compositions containing the polymers and a coated substrate coated with the coating composition. The emulsion polymer is formed by first combining hydrophobic polymeric compound and .alpha.,.beta.-ethylenically unsaturated monomer, and surfactant to form a mixture and subjecting the mixture to high stress techniques to form stabilized particles of the hydrophobic polymer and monomers, in the aqueous phase, said particles having a particle size between 50 and 500 nm. The polymerizable material within the particles is polymerized to form a hydrophobically modified core polymer. Additional monomers including at least one .alpha...beta.-ethylenically unsaturated hydrophilic monomer are then added to the core polymer and polymerized by emulsion polymerization, to form a hydrophobically modified core-shell emulsion polymer. To form a coating composition, the emulsion polymer is combined with additional components such as pigments, crosslinkers, plasticizers and solvents. The coating is applied to a substrate to form a coated article.

Title: Atrial and ventricular capture detection and threshold-seeking pacemaker
Inventor: MARKOWITZ H TOBY
IPC: A61N1/37
Filed: 1995-07-31
Abstract: Capture detection and stimulation threshold-measurement methods and apparatus for deriving atrial and ventricular pace pulse (A-pace and V-pace) stimulation energy strength-duration data. In a first atrial and ventricular threshold test regimen for use with patients having intact A-V conduction of first degree AV block, A-pace pulses are delivered at a test escape interval and A-V  delay. Atrial loss of capture (ALOC) in response to an A-pace test stimulus is declared by the absence of a detected ventricular depolarization (V-event) in the latter portion of the paced A-V delay interval following the delivery of the A-pace test stimulus. In the ventricular threshold test regimen, a V-pace test stimulus is delivered after a shortened A-V delay. Ventricular loss of capture (VLOC) is declared by the detection of a V-event in the ventricular refractory period of the V-pace test stimulus. In a second algorithm for use in the atrium or ventricle in patients having regular measured sinus rhythm, premature A-pace or V-pace test stimuli are delivered, and the presence of an A-event or V-event at the end of the measured sinus escape interval is declared to be ALOC or VLOC, respectively. A-pace and V-pace test stimuli are repeated to confirm capture declarations at an energy exceeding the LOC test energy. The atrial and ventricular stimulation threshold data derived by varying both pulse amplitude (strength) and width (duration) is stored in memory for telemetry out and analysis and for use in setting the V-pace and A-pace normal pulse width and amplitude used between successive auto-capture tests in order to conserve battery energy.
