20090039949 | METHOD AND APPARATUS FOR PRODUCING A LOW-NOISE, TEMPERATURE-COMPENSATED BANDGAP VOLTAGE REFERENCE - A bandgap voltage reference circuit is achieved that does not resort to the use of resistors or regulation loops and is thus able to achieve improved noise performance while also exhibiting absolute stability, no start-up issues, and low input-voltage operation. Subcircuits comprised of four interconnected transistors of different junction areas are used to create differential base-emitter voltage sources with magnitudes that vary in direct proportion to absolute temperature. The voltages from several of these subcircuits are combined without resistors to create a voltage source that is proportional to absolute temperature. An additional transistor is operated as a forward-biased PN junction to create a voltage source that varies in a sense that is complementary to absolute temperature. By a judicious choice of the transistor-junction-area ratios and the number of subcircuits that are summed, the combination of the complementary and proportional voltage references produces a bandgap voltage reference that is nearly constant with variations in temperature. The unique summation technique presented results in a bandgap reference with a noise performance that is more than an order of magnitude better than the prior art, particularly for applications requiring low current consumption. | 02-12-2009 |

20130323010 | TURBINE COOLANT SUPPLY SYSTEM - A gas turbine engine configured to rotate in a circumferential direction about an axis extending through a center of the gas turbine engine comprises a turbine stage. The turbine stage comprises a disk, a plurality of blades and a mini-disk. The disk comprises an outer diameter edge having slots, an inner diameter bore surrounding the axis, a forward face, and an aft face. The plurality of blades is coupled to the slots. The mini-disk is coupled to the aft face of the rotor to define a cooling plenum therebetween in order to direct cooling air to the slots. In one embodiment of the invention, the cooling plenum is connected to a radially inner compressor bleed air inlet through all rotating components so that cooling air passes against the inner diameter bore. | 12-05-2013 |

20130269949 | Cold Heavy Oil Production System and Methods - A system for producing hydrocarbons and sand from a formation includes a wellbore having a substantially horizontal portion. In addition, the system includes a liner disposed in the substantially horizontal portion. The liner has a longitudinal axis and includes a plurality of slots. Each slot is configured to pass sand from the formation into the wellbore. Further, the system includes a production string extending through the wellbore. Still further, the system includes a pump disposed at a downhole end of the production string in the liner. The pump has a central axis, an outlet coupled to the downhole end of the production tubing, and an inlet distal the production string. The pump is configured to pump hydrocarbons and sand from the formation to the surface. The central axis of the pump is oriented at an angle α measured downward from vertical. The angle α is between 60° and 90°. | 10-17-2013 |

20100326651 | ISOTOPIC IDENTIFICATION OF PRODUCTION BY INDIVIDUAL FORMATIONS IN COMMINGLED GAS WELLS - A computer system and computerized method for allocating production among multiple formations produced by a hydrocarbon well, using isotopic concentration analysis. According to an aspect of the system and method, multiple single-formation isotopic concentration measurements of multiple hydrocarbon gases are taken from each formation. Within each formation, groups of similar isotopic concentration values are defined, and are mapped to geographic regions of the formations. Mixing equations are developed between regions of the different formations, for use in allocating production for a well intersecting those regions. According to another aspect of the system and method, allocation among three or more formations is performed using Monte Carlo analysis of an underspecified mixing equation, and at a measured isotopic concentration value for the commingled flow from the well. | 12-30-2010 |
