20100212881 | Dual Mini Well Surface Control System - A well surface control system for use with various types of work strings such as, but not limited to, drill strings, coiled tubing, snubbing pipe, electric line, production tubing, and wireline. The system includes a main housing with a main bore extending from one end to the other. The main housing is equipped with a side port which communicates with the main bore between the two ends. The main housing is also equipped with two valves for controlling fluid and/or gas flows through the main bore and for severing a component of a work string running through the main bore. The first valve is positioned between the side port and one end of the main housing and the second valve is positioned between the side port and the other end of the main housing. Attached to each end of the main housing is a saver sub, with means for temporarily locking the saver subs to the main housing to prevent circular and longitudinal movement of the saver subs in relation to the main housing. | 08-26-2010 |

20090238735 | System and Method for Extending the Range of Hydrocarbon Feeds in Gas Crackers - In a system for thermal cracking gaseous feedstocks, the system including a gas cracker for producing an effluent comprising olefins, at least one transfer line exchanger for the recovery of process energy from the effluent and a water quench tower system, a process for extending the range of system feedstocks to include liquid feedstocks that yield tar is provided. The process includes the steps of injecting a first quench fluid downstream of the at least one transfer line exchanger to quench the process effluent comprising olefins, separating in a separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to the water quench tower system and quenching the separated cracked product with a second quench fluid to produce a cracked gas effluent for recovery and a second byproduct stream comprising tar. An apparatus for cracking a liquid hydrocarbon feedstock that yield tar is also provided. | 09-24-2009 |
20090280042 | Controlling Tar By Quenching Cracked Effluent From A Liquid Fed Gas Cracker - In a system for thermal cracking gaseous feedstocks, the system including a gas cracker for producing an effluent comprising olefins, at least one transfer line exchanger for the recovery of process energy from the effluent and a water quench tower system, a process for extending the range of system feedstocks to include liquid feedstocks that yield tar is provided. The process includes the steps of injecting a first quench fluid downstream of a primary transfer line exchanger to quench the process effluent comprising olefins, separating in a first separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to a water quench tower system and quenching the separated cracked product with a second quench fluid to produce a cracked gas effluent for recovery and a second byproduct stream comprising tar. An apparatus for carrying out such process is also provided. | 11-12-2009 |

20140359170 | SYNCHRONIZING DEVICE ASSOCIATION DATA AMONG COMPUTING DEVICES - Device association data for peripheral devices, which is data used to connect to the peripheral devices, is maintained and synchronized across multiple computing devices associated with a user account on a service. When a new peripheral device is associated with a computing device, device association data for the new peripheral device is added to the computing device. The device association data for the new peripheral device is also sent to the service, which provides the device association to the other computing devices from which the user logs into his or her account, and those other computing devices in turn automatically associate themselves with the peripheral device. Device use data describing how a user desires to use the peripheral device on one computing device, as well as changes to the device association data on one computing device, can similarly be synchronized across the multiple computing devices. | 12-04-2014 |

20160093087 | LOW LATENCY INK RENDERING PIPELINE - Systems and methods are provided for improving the latency for display of ink during user creation of ink content with a stylus, mouse, finger (or other touch input), or other drawing device for tracing a desired location for ink content in a display area. In order to reduce or minimize the time for display of ink content created by a user using a stylus/mouse/touch input/other device, a separate ink rendering process thread can be used that operates within the operating system and in parallel to other application threads. When it is desired to create ink content within an application, user interactions corresponding to creation of ink content can be handled by the separate ink rendering process thread. This can avoid potential delays in displaying ink content due to an application handling other events in a process flow. | 03-31-2016 |
