Inventor: DONDERICI BURKAY
IPC: G01V3/08
Filed: 2010-06-29
Abstract: Various logging-while-drilling (LWD) systems and methods provide resistivity logging coupled with deep detection of elongated anomalies at acute angles, enabling effective geosteering without disrupting drilling operations and without requiring intervention in the operations of the existing well. One LWD system embodiment employs a tool having tilted antennas as the transmitter and the receiver, where at least one of the antennas is placed in the vicinity of the bit, making it possible to detect existing wells at distances of 50-100 feet. In some cases, the detection distance is increased by enhancing the visibility of the existing well using a contrast fluid treatment on target well, either to fill the bore or to surround the well with treated cement or fluids that invade the formation. At least one inversion method separates the inversion of formation parameters from the inversion of parameters specifying distance, direction, and orientation of the existing well.

IPC: B01D1/00
Filed: 2011-08-10
Abstract: A fermentation liquid feed including water and a product alcohol and optionally CO2 is at least partially vaporized such that a vapor stream is produced.

Title: Method and system for removing mature fine tailings of a desired density from a tailings pond
Inventor: SVORCAN RADE
IPC: B03B9/02
Filed: 2013-04-02
Abstract: A method and a system for removal of Mature Fine Tailings (MFT) out of oilsands tailings ponds, specifically enabling year-round removal of MFT which density is greater than 1.35 t/m3. It utilizes a hollow, essentially fully enclosed around its perimeter, ideally of cylindrical form structure, (henceforth called the "structure") (5) of predetermined geometry, which is placed at the pond surface as shown in Figure 2. Water and less dense MFT initially located within the structure is moved outside the structure, while the MFT of required density which is surrounding the structure enters it under the action of hydrostatic pressure as per Figure 6. Continuous MFT removal operation is enabled due to simultaneous inflow of MFT  surrounding the structure so that the hydrostatic equilibrium as per Formula 1 noted herein is maintained.

Abstract: Apparatus and methods for automatically recalibrating an output current range of a user output current control encoder (140, 240) of an auto - reconnect welding/cutting device (100). When an input power type connected to an auto - reconnect device is changed, the calibrated range of the user output current control encoder (e.g., output control knob) is automatically transformed in response to the auto - reconnect device sensing at least one characteristic of the input power type. As a result, when a user adjusts the encoder to its maximum full-scale setting, too much current will not be drawn by the auto - reconnect device which would cause a circuit protection component (e.g., a circuit breaker or a fuse) associated with the input power type to trip. Instead, the current that is drawn when the encoder is set to the maximum full-scale setting is no more than about a rated current of the circuit protection component.

Abstract: A gas storage container may be filled with gas under pressure by feeding cryogenic fluid comprising liquefied gas into the container through a first conduit arrangement in a nozzle inserted into a passageway through a fluid flow control unit mounted in an opening in said container; closing the container to the passage of gas into or out of said container; and allowing said cryogenic fluid to become gaseous within the closed container. The invention involves venting displaced air and/or gaseous cryogenic fluid from said container during the feeding step through a second conduit arrangement in the nozzle. In embodiments in which displaced air and/or gaseous cryogenic fluid flows through the second conduit arrangement around a length of the first conduit arrangement, heat transfer from the fluid flow control unit to said cryogenic fluid is suppressed thereby reducing the level of evaporation of the cryogenic fluid in the nozzle during fill.

Abstract: A method and apparatus are provided for the differential diagnosis of a patient with progressive supranuclear palsy (PSP) from a patient with Parkinson's disease (PD). One method includes identifying a plurality of partially repetitive eye movements that over time define square wave jerks, each square wave jerk of the plurality of square wave jerks defined by a first horizontal saccadic movement that moves the eye away from a fixation target followed by a corrective saccadic movement towards the target shortly thereafter, measuring a vertical component associated with the plurality of square wave jerks, comparing the vertical component with a threshold value. PSP or PD is identified by comparison of the vertical component with the threshold value. In another embodiment, a patient's saccade rate is determined and compared to a threshold value, and PSP or PD is identified based upon the comparison of the saccade rate with the threshold value.

Title: Battery pack cooling and charging device and method
Inventor: CHEN MING
IPC: H01M10/44
Filed: 2013-09-26
Abstract: A battery pack cooling and charging device includes a charging module for a battery pack, a cooling fan, a power source module and a cooling fan control module.  The cooling fan control module is capable of controlling the cooling fan for cooling and is connected with the cooling fan. During the charging operation, a rotational speed of the cooling fan for cooling the battery pack and a charging module is changed by detecting parameters such as fan operation time, a battery pack internal resistance, a charging module temperature, and a battery pack voltage. The rotational speed of the cooling fan is reasonably adjusted, thus noise of the cooling fan is reduced and energy consumption is reduced according to different phases of the charging process by regarding one parameter or combinations of parameters as conditions for changing the rotational speed of the fan.
