There is described an invert emulsion wellbore fluid that includes: an oleaginous external phase; a non-oleaginous internal phase; an emulsifier; and a rheological additive comprising a sulphonated polymer formed from 100 to 10,000 monomers. There is also described a method of drilling a subterranean hole using the invert emulsion drilling fluid.

The invention provides a display interface in a social networking system that enables the presentation of information related to a user in a timeline or map view. The system accesses information about a user of a social networking system, including both data about the user and social network activities related to the user. The system then selects one or more of these pieces of data and/or activities from a certain time period and gathers them into timeline units based on their relatedness and their relevance to users. These timeline units are ranked by relevance to the user, and are used to generate a timeline or map view for the user containing visual representations of the timeline units organized by location or time. The timeline or map view is then provided to other users of the social networking system that wish to view information about the user.

A touch-screen display apparatus, the apparatus may include first and second sheets having opposed major surfaces and a size and shape defined by a periphery. The periphery may be defined by opposed ends and opposed edges. The first and second sheets may each have a conductive pattern including a pair of opposed busbars and a plurality of traces electrically coupled to, and extending between, corresponding pairs of opposed busbars. The transparent force sensing (TFS) sheet may have opposed major surfaces and a variable resistance which is related to a force exerted upon one or more of its major surfaces. The TFS sheet may be situated between the first and second sheets. The apparatus may also include one or more separation portions situated between the TFS sheet and the first or second sheet to bias the TFS sheet apart from the first or second sheet.

A method for controlling a printer via a server computer comprises, spooling a file including a hierarchy of a print ticket attached with a fixed document and a fixed page, in response to a print job on a client computer, creating print data from a spooled file, processing a print job, storing, using a CPU, a copy of the spooled file during the processing of the print job, receiving a request to redirect, and sending a modified copy of the spool file to another printer after the request to redirect is received.
摘要:
A method of cleaning a wellbore drilled with an oil-based drilling fluid that forms an oil-based filter cake where the method includes: emplacing a breaker fluid into the wellbore, the breaker fluid comprising: a water-miscible non-aqueous fluid; at least one weighting salt; and at least one breaking agent; and shutting in the well for a period of time sufficient to initiate breaking of the oil-based filter cake is disclosed.
摘要:
The gate valve includes a valve housing (12) having a fluid conduit (14) and defining a valve seat (16) and a support surface (18), a seal plate (20), a counter plate (22) having cushion (72) vulcanized to a surface facing the support surface (18), and an actuator (34) for moving the seal plate and the counter plate between respective open and closed positions. The cushion is configured to prevent metal-to-metal contact between the counter plate and the support surface of the valve housing.
摘要:
A method of improving the lubricity of an aqueous based drilling fluid composed of an aqueous base fluid, and a weighting agent. The method involves the addition of an effective amount of a phospholipid to substantially reduce the coefficient of friction when compared to the fluid absent the phospholipids. Preferably the phospholipids have the structure: in which R and R′ are C6 to C25 hydrocarbon groups; and A is an anion to counter the cationic charge.

The proliferation of uterine fibroid leiomyoma cells is inhibited by certain Fibroid Cell Growth Inhibitor (FGI) agents. Pharmacological doses of FGI agents can be made high enough to not only inhibit proliferation, but to cause cell death. Non-invasive or minimally invasive, non-systemic delivery methods deliver the FGI agent to the target fibroid leiomyoma cell population, thereby avoiding the disadvantages and side effects of surgical and systemic hormonal therapy interventions for treatment of uterine fibroids. The FGI agents are substrates normally present and well tolerated in humans. The efficacy of the FGI agents relates to their ability to moderate Protein Kinase C and Mitogen Activated Protein Kinase pathways. Specific FGI agents shown to be useful to inhibit growth of uterine fibroid cells include: α-tocopherol, α-tocopherol succinate, and troglitazone. Delivery of FGI agents to the target uterine fibroid cells may be accomplished by intra-vaginal and in situ injection techniques.
摘要:
A method and apparatus for controlling an interactive human-machine interface, which includes an input device and comprises a set of states. The set of states form a network through which data can be passed as a token. In a dialogue control unit, future states are assessed to determine allowable user inputs that may be received from the user. Each portion of the user input is stored in an associated node of the token, for use in the current state or in another of the active states. Each node is checked to see if it relates to the current state, and if so, then the portion of the user input stored in the node is processed.
