| 20100147693 | DEVICE AND METHOD FOR MANUFACTURING A PARTICULATE FILTER WITH REGULARLY SPACED MICROPORES - Various embodiments disclose devices and methods for fabricating microporous particulate filters with regularly spaced pores wherein sheet membrane substrates are exposed to energetic particle radiation through a mask and the damaged regions removed in a suitable developer. The required depth of field is achieved by using energetic particles to minimize diffraction and an energetic particle source with suitably small diameter. | 06-17-2010 |
| 20100107646 | SHAPE MEMORY ALLOY ACTUATED ADAPTIVE EXHAUST NOZZLE FOR JET ENGINE - The proposed adaptive exhaust nozzle features an innovative use of the shape memory alloy (SMA) actuators for actively control of the opening area of the exhaust nozzle for jet engines. The SMA actuators remotely control the opening area of the exhaust nozzle through a set of mechanism. An important advantage of using SMA actuators is the reduction of weight of the actuator system for variable area exhaust nozzle. Another advantage is that the SMA actuator can be activated using the heat from the exhaust and eliminate the need of other energy source. A prototype has been designed and fabricated. The functionality of the proposed SMA actuated adaptive exhaust nozzle is verified in the open-loop tests. | 05-06-2010 |
| 20100090175 | NANOCOMPOSITES OF POLYMERS WITH DISPERSED NANOTUBES - The present invention provides polymer nanocomposites with dispersed nanotubes and methods of making same. The polymer may be a polyether. For example, the present invention provides an effective method to successfully disperse single walled nanotubes (SWNTs) into both Polyethylenoxide (PEO) and its low molecular weight analog polyethylene glycol (PEG) with hydrodynamic percolation at about 0.09 wt % and an electrical percolation at about 0.03 wt % SWNTs at room temperature, and the resulting nanocomposites. The method may include providing a surfactant. Most notably the present inventors achieved a decrease in the melting point of the polymer and a retardation of polymer crystallization due to the presence of the nanotubes. | 04-15-2010 |
| 20080258719 | APPARATUS AND METHODS FOR FERROMAGNETIC WALL INSPECTION OF TUBULARS - Apparatus and methods for magnetic wall inspecting materials such as cylindrical and tubular members are disclosed. One apparatus includes a main magnetic coil producing lines of magnetic flux able to traverse a section of a tubular member in a direction generally parallel to a longitudinal axis of the tubular member; and one or more magnetic focusing members positioned along the tubular and able to redirect certain flux lines so that they are more parallel to the tubular. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b). | 10-23-2008 |
