20100294317 | Separation Vessel for Solids Removal - A separation device for removing solids from an input stream is provided, comprising a vessel, such as a production vessel or storage tank, having an inlet for receiving an input stream containing fluids, such as oil and water, and solids, such as sand and silt. The vessel also includes a fluid outlet and a drain outlet. An optional fluid recirculation and injection device is mounted inside the vessel and delivers fluid to facilitate removal of the solids through the drain outlet. The vessel also includes an agitation or flighted device mounted adjacent to the drain outlet for contacting and dislodging solids which have settled within the vessel. The agitation device includes a rotatable shaft driven by a motor, and an agitation element, such as an auger, to break up the solids and move them toward the drain outlet. A method of removing solids is also provided using the auger device. | 11-25-2010 |
20130168291 | Method, Apparatus and System for Hydrocarbon Recovery - The present invention relates to a system, method and apparatus for the extraction of hydrocarbons from contaminated solids. The method for separating hydrocarbons from solids comprising exposing the solid to a heat source of sufficient temperature to release substantially all of the hydrocarbon and water from the solids as volatile vapors, condensing at least a portion of the hydrocarbon vapor, and condensing the water vapor. The apparatus for extracting hydrocarbons from solids comprises a heat source capable of reaching temperatures sufficient to vaporize substantially all of the hydrocarbons in the contaminated solids and at least one separation tank in fluid communication with an outlet of said heat source for condensing at least part of the hydrocarbons. The present invention also relates the system for applying said method to said apparatus to extract and recover hydrocarbons from contaminated solids. | 07-04-2013 |

20120201175 | FILTERING USING IMPEDANCE TRANSLATOR - This disclosure relates to low noise amplifiers (LNAs) and more particularly to LNAs integrated on integrated circuit (IC) chips along with radio frequency (RF) amplifiers. In one implementation, an impedance translator is coupled to an amplifier, the impedance translator to cause the amplifier to selectively amplify the one or more components of a received signal. | 08-09-2012 |
20130208631 | Cancellation of RF Second-Order Intermodulation Distortion - The disclosed invention relates to a transceiver system configured to cancel RF second-order intermodulation distortion (IMD2) within a differential reception path. In some embodiments, the transceiver system has one or more common-mode attenuation elements that attenuate common-mode interferer signals within the differential reception path. The common-mode attenuation elements detect a common-mode interferer from one or more nodes within a transceiver system front-end. One or more properties of the detected common-mode interferer are adjusted and then fed into the differential reception path, where the adjusted common-mode signal attenuates the common-mode interferers. In other embodiments, the differential reception path has a tunable amplifying stage. The tunable amplifying stage has first and second amplifier elements that are independently operated to intentionally introduce an operating parameter mismatch between the elements. The intentional mismatch may be tuned to account for different nonlinear responses of the amplifier elements to mitigate IMD2 within the differential reception path. | 08-15-2013 |
