Systems and methods for redacting portions of a document resulting in one or more versions of the document that show to readers the portions of the document that have been redacted. At least one of these one or more versions may have the content of the redacted portions encrypted and/or actually removed and replaced with a sort of filler (e.g., to resemble a blacked out portion of a paper copy). At least one other version may show to users the actual content that has been redacted. This latter version may be retained for users privy to the content (i.e., information) of the redacted portions, so that they know what content was redacted, whereas versions with the content removed or encrypted may be provided to those not privy to the content.

A system and methods for protecting a metal surface from corrosion are provided herein. The method includes injecting particles comprising a sacrificial anodic material into a fluid proximate to the metal surface.
摘要:
A rectifier assembly includes individual diodes arranged to form a full-wave bridge such that the silicon wafers of the diodes are loaded in compression. As so arranged, the centrifugal forces add to the compression forces on the diodes and on the electrical contacts therewith. The three-phase (AC) input conductors are connected by conductive straps which connect the diodes through to DC (+/−) terminal ring outputs. One surface of each of the diodes is in electrical contact with a conductive strap which then connects with the individual (AC) phases of an exciter rotor winding. The opposing surface of the diode contacts the ring diode pad on either the DC (+/−) output terminal ring. Two conductive posts, each of which are connected to only one of the DC (+/−) output terminal rings permit external connection to a main rotor winding.

An apparatus for achieving weight loss in a patient is disclosed. The apparatus has a barrier material and an applicator for dispensing the barrier material about the intestine. An injector is used to place the barrier material to block nutrient transfer from the intestine into the blood stream. The barrier material is a polymerizable adhesive that can be injected interstitially between layers of the intestine, or injected into vascular structures to partially block the flow of blood to the nutrient absorbing layers.

A design for a suture for use in suture appositioning techniques, and a method for use are disclosed. In one embodiment the suture may comprise a hollow length having a wall forming a lumen, which may serve as a conduit through which fluid may be pumped and discharged through a plurality of perforations in the wall. In another embodiment the suture may comprise a plurality of suture members connected by a connecting member. In one embodiment of a method disclosed, a suture having a hollow length having a wall forming a lumen, with a plurality of perforations in the wall, may be placed in a stitching procedure to apposition tissues, and a fluid such as an adhesive, adhesive activating agent or drug may be pumped through the lumen and discharged out the perforations for various beneficial effects.
摘要:
The present techniques are directed to systems and methods for displacing a structure in a fluid handling system with a displacement fluid. A system includes a plurality of storage conduits that can hold a treatment fluid or a barrier fluid. The treatment and barrier fluids are transferred from the storage conduits by a displacement fluid using a driver.
摘要:
A method and systems are provided for injecting a hydrate slurry into a reservoir. The method includes combining gas and water within a subsea simultaneous water and gas (SWAG) injection system. The method also includes forming a hydrate slurry from the gas and the water, and injecting the hydrate slurry into a reservoir.
摘要:
Embodiments described herein provide a system and methods for protecting a fluid stream from fouling using particles that include phase change materials. In an example, the particles are injected into the fluid stream and release energy at a selected temperature, which may warm the fluid stream.
摘要:
Methods and systems are provided for producing hydrocarbons from production fluids that have water as an external phase. An exemplary embodiment provides a method that comprises producing a production fluid having water as the external phase and injecting an amount of a thermodynamic hydrate inhibitor into the production fluid, wherein the amount is adjusted to allow hydrate formation to occur while retaining liquid water as the external phase. The water and thermodynamic hydrate inhibitor may be separated from the production fluid and a purified hydrocarbon stream may be produced.
摘要:
Provided are apparatus, systems, and methods for generating a non-plugging hydrate slurry. The apparatus, systems, and methods for generating a hydrate slurry are useful for transport and/or production of wellstream hydrocarbons in subsea and arctic environments. The present invention provides methods of seeded or unseeded methods of making dry hydrates. Dry hydrates are made with or without the aid of chemicals and, preferably, with minimum use of rotating or other energized equipment.
