20140158359 | Methods for Increasing Subterranean Formation Permeability - Methods for increasing the permeability of a portion of a subterranean formation surrounding a wellbore using non-hydrolyzed liquid esters to attack carbonates within acid-soluble formations without requiring the use of a catalyst or enzyme. Some methods comprise providing a treatment fluid comprising a non-hydrolyzed liquid ester in a base fluid; introducing the treatment fluid into a subterranean formation at matrix flow rates to allow the non-hydrolyzed liquid ester to penetrate into at least a portion of the subterranean formation; and leaving the treatment fluid in contact with the subterranean formation for a period of time during which at least a portion of the non-hydrolyzed liquid ester hydrolyzes to produce an acid. | 06-12-2014 |

20140060004 | TILTROTOR VECTORED EXHAUST SYSTEM - The exhaust system is located on each nacelle of a tiltrotor aircraft. The exhaust system includes a vector nozzle that is selectively rotatable in relation to each nacelle in order to achieve certain performance objectives. The vector nozzle can be oriented to provide maximum flight performance, reduce infrared (IR) signature, or even to reduce/prevent ground heating. | 03-06-2014 |

20160030839 | MODIFYING A SIMULATED CHARACTER BY DIRECT MANIPULATION - A portion of a simulated element of a graphical simulation available for modification is identified in view of a cursor location associated with a user input device. The identified portion of the simulated element is selected for modification. The selected portion of the simulated element is then modified according to a direct manipulation of a display of the selected portion of the simulated element by a user using the user input device. | 02-04-2016 |
