| 20090191076 | TUNABLE CHOKE TUBE FOR PULSATION CONTROL DEVICE USED WITH GAS COMPRESSOR - A method and system for reducing pulsation in a gas compressor system. A pulsation control device, such as a filter bottle or side branch absorber, is installed at a port into some location on the compressor system. The pulsation control device has a choke tube with a variable cross-sectional area, such as by having multiple conduits that may be opened or closed or a diameter that may be varied. In operation, the cross sectional area of the choke tube is varied depending on the compressor speed. | 07-30-2009 |

| 20100329899 | MULTI-FREQUENCY PULSATION ABSORBER AT CYLINDER VALVE CAP - A multi-chambered pulsation absorber for attachment over the valve cap opening of a compressor cylinder. Each chamber is in fluid communication with the valve cap opening (or cylinder internal gas passages) via an associated choke tube. Each pairing of a chamber with a choke tube is tuned, in the manner of a Helmholz resonator, to attenuate and nearly eliminate a different cylinder-related pulsation frequency, such as those resulting from internal cylinder pulsations or cylinder nozzle pulsations. | 12-30-2010 |
| 20110243760 | Pressure Recovery Insert for Reciprocating Gas Compressor - A method of reducing pulsations in a reciprocating compressor system, the system having nozzles between cylinders and filter bottles of the compressor system, the nozzles attaching at ports of the cylinders and filter bottles. A special insert is designed to be placed in one or more of the nozzle. The insert is generally cylindrical, but has a narrowed throat, a flared inlet end, and a flared outlet end. The insert dimensions, such as the inner diameter of the throat and the distance from the throat to the outlet end are calculated to reduce pulsations as well as provide pressure recovery. | 10-06-2011 |

| 20110144758 | GLENOID AUGMENT AND ASSOCIATED METHOD - A augmented glenoid implant assembly for use in performing shoulder arthroplasty is provided. The augmented glenoid implant assembly is used for cooperation with the glenoid fossa of a scapula. The implant assembly includes a first component for attachment to the scapula. The first component defines a support surface for cooperation with the glenoid fossa, a second surface positioned adjacent a buttress formed in the glenoid fossa and an assembly surface. The implant assembly also includes a second component removably secured to the first component. The second component includes an assembly face of the second component. The assembly surface of the second component is in close approximation to the assembly surface of the first component. The second component further includes an articulating surface opposed to the assembly surface. | 06-16-2011 |
| 20110153023 | MODULAR GLENOID PROSTHESIS AND ASSOCIATED METHOD - A glenoid implant assembly is provided. The assembly includes a first component for attachment to the glenoid fossa of a scapula. The component defines an assembly face of the component. The assembly also includes a second component removably secured to the first component. The second component includes an assembly face of the second component. The assembly face of the second component is in close approximation to the assembly face of the first component. The second component is attachable to the first component in a direction generally normal to the assembly faces. | 06-23-2011 |

| 20090248378 | Method For Geologic Modeling Through Hydrodynamics-Based Gridding (Hydro-Grids) - A method of hydrodynamics-based gridding (Hydro-Grids) for creating geologic models of subsurface volumes, such as reservoirs, is disclosed. Geologic data is obtained. Vertical grid surfaces are created. Lateral grid surfaces are created to correspond to surfaces of constant geologic time during the deposition of sediments in the subsurface volume. Geologic properties within each cell are represented as values within each cell created by the vertical and lateral surfaces. Reservoir performance is simulated using the represented geologic properties of the subsurface volume. A hydrocarbon reservoir is developed based on the simulated reservoir performance. | 10-01-2009 |

| 20090135670 | Method For Combining Seismic Data Sets - A method is disclosed for combining seismic data sets. This method has application in merging data sets of different vintages, merging data sets collected using different acquisition technologies, and merging data sets acquired using different types of sensors, for example merging hydrophone and geophone measurements in ocean bottom seismic data. In one embodiment, a desired data trace is to be determined from a set of measured data traces, and the following steps are applied: (a) model filters are constructed which express the deterministic relationship between the desired data trace and each available measured trace that depends on the desired data trace; (b) the noise properties associated with each measured data trace are determined; (c) a sufficient statistic for the desired data trace is formed by application of an appropriate filter to each measured trace and summing the filter outputs; (d) the sufficient statistic is further processed by a single-input single-output estimator to construct an estimate of the desired data trace from the sufficient statistic. | 05-28-2009 |
| 20090204377 | Method for Constructing Geologic Models of Subsurface Sedimentary Volumes - A method is disclosed for using a three-dimensional seismic image of a subsurface earth volume to construct a geologic model specifying the spatially-varying grain size distribution, porosity, and permeability throughout the volume. The method applies to earth volumes composed of water-lain clastic sedimentary deposits and involves, in one embodiment, (a) identifying the outline forms of geologic bodies in geologic data; (b) using the outline forms of the geologic bodies to determine the spatially-varying grain size distribution within the bodies, guided by assumptions about the nature and behavior of the paleoflow that deposited the bodies; (c) determining rock properties such as, porosity and permeability within the geologic bodies based on grain-size distribution, mineralogy and burial history information. | 08-13-2009 |
| 20100198638 | METHOD FOR DETERMINING THE PROPERTIES OF HYDROCARBON RESERVOIRS FROM GEOPHYSICAL DATA - A hydrocarbon exploration method is disclosed for developing a model of at least one effective material property of a subsurface reservoir as a function of the composition and structure of the reservoir rock. In one embodiment, the method comprises: obtaining a 3D image ( | 08-05-2010 |

| 20110125977 | ALIGNING DATA STORAGE DEVICE PARTITION TO BOUNDARY OF PHYSICAL DATA SECTOR - A method of aligning a partition of a data storage device to a boundary of a physical data sector is disclosed. The data storage device comprises a non-volatile memory comprising a plurality of physical data sectors, wherein each physical data sector comprises a plurality of logical data sectors. A partition map is read from the non-volatile memory, wherein the partition map identifies a partition comprising a number of logical data sectors. A number of logical data sectors in each physical data sector is determined. Whether at least part of the partition aligns with a boundary of a physical data sector is determined. When at least part of the partition does not align with a boundary of a physical data sector, at least part of the partition is moved to align at least part of the partition to a boundary of a physical data sector. | 05-26-2011 |
