20090155472 | BUILDING MATERIAL COMPOSITION, ESPECIALLY BITUMEN-FREE SEALANT - The invention relates to a building material composition which is suitable in particular for use as a bitumen-free sealant for sealing structures and contains a polymer dispersion or a corresponding redispersion powder, in particular based preferably on emulsion polymers which are redispersible in an aqueous medium, together with polystyrene particles, hollow ceramic and synthetic microspheres and, if appropriate, at least one binder and, if appropriate, further additives. The sealant according to the invention can in principle be formulated as a 1C or 2C application system. In addition to excellent sealing properties, as can conventionally be achieved only with bitumen-containing sealants, the bitumen-free building material composition according to the invention shows in particular excellent shrinkage behavior after application. | 06-18-2009 |

20100281890 | Refrigerant Charging System and Method for Using Vapor-Phase Refrigerant - A refrigerant charging system and method for charging a refrigeration system with a vapor-phase refrigerant includes a refrigerant source, an input line, a sensor and a pressure regulator. The input line connects the refrigerant source to the refrigeration system. One or more valves are disposed between the refrigerant source and refrigeration system to regulate the pressure of the refrigerant being introduced into the refrigeration system, and the sensor measures the pressure of the refrigerant entering the refrigeration system. A pressure regulator can also be used to regulate the flow of refrigerant. Once the pressure of the refrigerant reaches a predetermined pressure, the refrigeration system is fully charged, and the transfer of refrigerant to the refrigeration system is stopped. The system and method are used to charge the refrigeration system of, e.g., an automotive vehicle, and the refrigeration is carbon dioxide. | 11-11-2010 |

20090253580 | Growth of Boron Nanostructures with Controlled Diameter - A process for growth of boron-based nanostructures, such as nanotubes and nanowires, with a controlled diameter and with controlled chemical (such as composition, doping) as well as physical (such as electrical and superconducting) properties is described. The boron nanostructures are grown on a metal-substituted MCM-41 template with pores having a uniform pore diameter of less than approximately 4 nm, and can be doped with a Group Ia or Group IIa electron donor element during or after growth of the nanostructure. Preliminary data based on magnetic susceptibility measurements suggest that Mg-doped boron nanotubes have a superconducting transition temperature on the order of 100 K. | 10-08-2009 |
20090325790 | SIZE-CONTROLLABLE TRANSITION METAL CLUSTERS IN MCM-41 FOR IMPROVING CHEMICAL CATALYSIS - A metal-substituted mesoporous oxide framework, such as Co-MCM-41, are disclosed which includes more than one ion species with different reduction kinetics. The reducibility correlates strongly with the pore radius of curvature, with the metal ions incorporated in smaller pores more resistant to complete reduction. The metal-ion substituted oxide framework improves catalytic processes by controlling the size of the catalytic particles forming in the pores. The metal-substituted mesoporous oxide framework can be employed in selective hydrogenation of organic chemicals, in ammonia synthesis, and in automotive catalytic exhaust systems. | 12-31-2009 |

20090184504 | EXPANDED METAL FILTERS - Expanded metal sheets are used to produce tubular filters. The expanded metal sheet has a multiplicity of rows of openings arranged to reduce nesting when the sheet is rolled on itself. In particular, the pitch between the rows of openings, the sizes of the openings, or both the pitch between the rows of openings and the sizes of the openings are varied to reduce nesting when the expanded metal sheet is rolled on itself. The filters can include external circumferential grooves, rounded corners produced by a point loading process, textured surfaces between openings, and/or torturous internal paths produced by non-perforated areas of an expanded metal sheet. The expanded metal sheet can be composed of carbon steel coated with a material having a higher heat conductivity, e.g., tin. Among other things, the filters can be used in automobile airbag inflators to capture slag and absorb heat produced by the inflator's explosive charge. | 07-23-2009 |
