| 20110033684 | FACER AND FACED POLYMERIC ROOFING BOARD - A prefabricated, faced roofing board composite includes a first board layer made of a polymeric material or a predominantly polymeric material and a fire and weather resistant fiberglass-based facer bonded to a top major surface of the first board layer and forming a top major surface of the composite. The fiberglass-based facer is substantially impervious to the passage of hot gases of combustion, water, and water vapor through the thickness of the fiberglass-based facer. The faced composite can be a cover board, an insulation board; can include cover board and insulation board layers; and can include cover board, insulation board, and baseboard layers. A second fiberglass-based facer that is substantially impervious to the passage of hot gases of combustion through its thickness can form a bottom major surface of the composite. The polymeric material or predominantly polymeric material of the board layer to which each fiberglass-based facer is bonded penetrates part of the way through, but not completely through, the fiberglass-based facer. | 02-10-2011 |
| 20110067872 | Wellbore Flow Control Devices Using Filter Media Containing Particulate Additives in a Foam Material - In one aspect a apparatus is provided that in one embodiment may include a permeable member made by combining a particulate additive to one or more materials, which materials when processed without the particulate additive form a substantially impermeable mass, wherein the permeable member inhibits flow of solid particles above a particular size through the permeable member. | 03-24-2011 |
| 20110132143 | NANOMATRIX POWDER METAL COMPACT - A powder metal compact is disclosed. The powder metal compact includes a substantially-continuous, cellular nanomatrix comprising a nanomatrix material. The compact also includes a plurality of dispersed particles comprising a particle core material that comprises Mg, Al, Zn or Mn, or a combination thereof, dispersed in the nanomatrix and a solid-state bond layer extending throughout the nanomatrix between the dispersed particles. The nanomatrix powder metal compacts are uniquely lightweight, high-strength materials that also provide uniquely selectable and controllable corrosion properties, including very rapid corrosion rates, useful for making a wide variety of degradable or disposable articles, including various downhole tools and components. | 06-09-2011 |
| 20110132612 | Telescopic Unit with Dissolvable Barrier - A telescopic member includes, at least a central component and a barrier disposed within the central component, the barrier has a selectively tailorable dissolution rate curve and has structural properties enabling the containment of high pressure prior to structural failure of the barrier through dissolution. | 06-09-2011 |
| 20110132619 | Dissolvable Tool and Method - A method of dissolving a tool includes, exposing an outer surface of the tool to an environment reactive with the tool, reacting the tool with the environment, applying stress to the tool, concentrating stress on the tool at stress risers in the outer surface, and initiating fracturing the tool at the stress risers. | 06-09-2011 |
| 20110132620 | Dissolvable Tool and Method - A method of dissolving a tool includes, positioning the tool within an environment reactive with at least a portion of the tool, introducing the environment below a surface of the tool through at least one perforation formed therein, reacting at least a portion of the tool exposed to the environment through the at least one perforation, weakening the tool to mechanical stress, and fracturing the tool. | 06-09-2011 |
| 20110132621 | Multi-Component Disappearing Tripping Ball and Method for Making the Same - A tripping ball including two or more relatively dissolution resistant parts of a ball and an adherent dissolvable material binding the two or more parts of the ball together and method for making a tripping ball as described. | 06-09-2011 |
| 20110135530 | METHOD OF MAKING A NANOMATRIX POWDER METAL COMPACT - A method of making a powder metal compact is disclosed. The method includes forming a coated metallic powder comprising a plurality of coated metallic powder particles having particle cores with nanoscale metallic coating layers disposed thereon, wherein the metallic coating layers have a chemical composition and the particle cores have a chemical composition that is different than the chemical composition of the metallic coating layers. The method also includes applying a predetermined temperature and a predetermined pressure to the coated powder particles sufficient to form a powder metal compact by solid-phase sintering of the nanoscale metallic coating layers of the plurality of coated powder particles to form a substantially-continuous, cellular nanomatrix of a nanomatrix material, a plurality of dispersed particles dispersed within the cellular nanomatrix and a solid-state bond layer extending throughout the cellular nanomatrix. | 06-09-2011 |
| 20110135953 | COATED METALLIC POWDER AND METHOD OF MAKING THE SAME - A metallic powder is disclosed. The metallic powder includes a plurality of metallic powder particles. Each powder particle includes a particle core. The particle core includes a core material comprising Mg, Al, Zn or Mn, or a combination thereof, having a melting temperature (T | 06-09-2011 |
| 20110136707 | ENGINEERED POWDER COMPACT COMPOSITE MATERIAL - An engineered dispersed particle-cellular nanomatrix composite material is disclosed. The engineered dispersed particle-cellular nanomatrix composite material is configured for contact with a fluid and configured to provide a selectable and controllable transition from one of a first strength condition to a second strength condition that is lower than a functional strength threshold, or a first weight loss amount to a second weight loss amount that is greater than a weight loss limit, as a function of a time in contact with the fluid. | 06-09-2011 |
