20090032353 | Apparatus with active material surface in contact with pheological fluid and method of enhancing performance thereof - An apparatus is provided having an active material forming a surface thereof in contact with a rheological fluid. The active material is controllable to vary a surface geometry thereof between a rough or nonsmooth surface geometry to increase drag, and achieve an increase in stress transmitted through the fluid, when a field is applied, while allowing a smooth surface geometry and an associated reduction in stress transmitted through the fluid when the field is removed. A method of enhancing performance of an apparatus that includes a rdeological fluid is also provided. | 02-05-2009 |
20090047489 | Composite article having adjustable surface morphology and methods of making and using - Disclosed are composite articles having adjustable surface morphologies, methods of making the composite articles, and methods of using the composite articles. The composite articles generally include an active layer comprising a shape memory material configured to undergo a change in property upon receipt of an activation signal, a bias layer configured to provide a mechanism for the composite article to return to a first shape from a second shape, and an activation device for providing the activation signal to the shape memory material. | 02-19-2009 |
20090068357 | MAGNESIUM-TITANIUM SOLID SOLUTION ALLOYS - Films of magnesium mixed with titanium are produced by non-equilibrium alloying processes such as electron beam evaporation of magnesium and titanium ingots in a very low pressure chamber. Such magnesium-titanium films form as single phase solid solutions. Titanium is inherently resistant to corrosion and its admixture with magnesium in solid solution provides a new composition that is less subject to intra-film galvanic corrosion. The magnesium-titanium films also provide relatively hard and strong coatings. | 03-12-2009 |
20090090325 | Piston Skirt Oil Retention for an Internal Combustion Engine - An internal combustion engine is provided having a cylinder case with at least one cylinder bore wall defining at least one cylinder bore. At least one piston is reciprocally movable within the at least one cylinder bore. The at least one piston includes at least one skirt portion preferably having a barrel-shaped profile. The cylinder bore wall has an oleophobic characteristic, while the at least one skirt portion has an oleophilic characteristic. The oleophobic and oleophilic characteristic is produced by at least one of coating and machining the at least one cylinder bore wall and the at least one skirt portion, respectively. | 04-09-2009 |
20090324937 | LAYERED COATING AND METHOD FOR FORMING THE SAME - A layered coating is disclosed herein.
