Abstract:
A method of making a composite downhole article is disclosed. The method include forming at least one removable core member comprising a first metallic material that is removable in a wellbore fluid at a first removal rate; and disposing at least one outer member on the core member, the outer member comprising a second material that is removable in the wellbore fluid at a second removal rate, wherein the removable core member has a composition gradient or a density gradient, or a combination thereof, and wherein the first removal rate is substantially greater than the second removal rate. A method of using a composite downhole article is also disclosed. The method includes forming a composite downhole article as described above; using the article to perform a first wellbore operation; exposing the article to the wellbore fluid; and selectively removing the second removable member.
Abstract:
A composite downhole article is disclosed. The article is selectively corrodible in a wellbore fluid. The article includes at least one corrodible core member comprising a metallic first material that is corrodible in a wellbore fluid at a first corrosion rate. The article also includes at least one outer member disposed on the core member and comprising a second material that is corrodible in the wellbore fluid at a second corrosion rate, wherein the corrodible core member has a composition gradient or a density gradient, or a combination thereof, and wherein the first corrosion rate is substantially greater than the second corrosion rate.
Abstract:
A cookware object, system and method of cooking are provided. The cookware object includes raised ridges and recessed channels within a base of the object that is designed to hold water (or other liquid), and a lid to retain/promote steam.
Abstract:
A method finds an error in a computer program. A plurality of execution breakpoints are set in the computer program. A portion of the execution of the computer program is simulated as recorded in the trace data in the reverse order until one a plurality of conditions is met, wherein one of the plurality of conditions is an attempt to execute a machine instruction associated with one of the plurality of execution breakpoints.
Abstract:
In one embodiment, the present invention includes a method for configuring a single chip radio tuner having a configurable front end, which may be adapted within an integrated circuit (IC). The method may include setting a controller of the tuner with configuration information for a radio in which the tuner is located. Then, control signals responsive to the configuration information can be sent to the configurable front end to configure the tuner.
Abstract:
A process for stabilizing particles includes disposing reactive nanoparticles in a borehole; contacting the reactive nanoparticles with a resin; introducing a curing agent; and curing the resin and reactive nanoparticles with the curing agent to form a nanocomposite, wherein, during curing, the nanocomposite is bonded to the particles to stabilize the particles. A process for consolidating particles includes coating the particles with a resin; introducing reactive nanoparticles; curing the resin and reactive nanoparticles with a curing agent to form a nanocomposite which is bonded to the particles; and controlling a rate of the curing by an amount of the curing agent which is present with the resin, wherein the nanocomposite bonded to the particles is thermally stable up to at least 600° F. (315° C.). A system comprises a resin; reactive nanoparticles; a curing agent to form a nanocomposite; and particles disposed in a downhole location to which the nanocomposite binds.

Abstract:
A heat exchanger has a multi-lumen tubing having one end connected to a supply fitting and another end connected to a return fitting. The tubing has a central lumen, a middle lumen that surrounds the central lumen and an outer lumen that surrounds the middle lumen. When infusate traverses along the heat exchanger, it is heated by the heating fluid that flows along the central lumen, and also by the rerouted heating fluid that flows along the outer lumen of the tubing. The heat exchanger is fluidly coupled to a heater by its inlet and outlet so that the temperature of the heating fluid for warming the infusate is maintained at a predetermined temperature.
Abstract:
An elbow for a solid particle conveyance system includes an elbow body having an inlet duct and an outlet duct with an interior space defined between the inlet and outlet ducts. An aeration insert is mounted to the elbow body for aerating solid particles passing through the interior space of the elbow body. The aeration insert is mounted to the elbow body to provide aeration from an elevation between that of the inlet duct and the outlet duct to facilitate downward movement of solid particles from the inlet duct across the aeration insert, and out through the outlet duct.
Abstract:
A composite particle comprises a core, a shielding layer deposited on the core, and further comprising an interlayer region formed at an interface of the shielding layer and the core, the interlayer region having a reactivity less than that of the core, and the shielding layer having a reactivity less than that of the interlayer region, a metallic layer not identical to the shielding layer and deposited on the shielding layer, the metallic layer having a reactivity less than that of the core, and optionally, an adhesion metal layer deposited on the metallic layer.
