20090293654 | Tortionally Stiff, Thermally Isolating Shaft Coupling with Multiple Degrees of Freedom to Accommodate Misalignment - A coupling arrangement coupling and thermally isolating a continuously variable electrical actuator rotationally coupled to and from a butterfly valve is provided. The valve may be used to modulate high temperature exhaust gas flow through an engine turbocharger. The actuator provides a continuously variable control of the valve. The coupling arrangement provides a thermal block to reduce heat transfer and vibration insulation between the actuator and the valve. The coupling arrangement generally includes a coupling shaft rotationally coupled at opposite ends to the input and output shafts by torsion spring mechanisms. The torsion spring mechanisms include yokes rotationally locking the coupling shaft to the input and output shafts. The torsion spring mechanisms allow a limited range of axial and pivotal translation between the coupling shaft and the input and output shafts and are preloaded to prevent rotational hysteresis in the valve. | 12-03-2009 |

20120280179 | Self-Regulating Gas Generator and Method - A self-regulating gas generator that, in response to gas demand, supplies and automatically adjusts the amount of gas (e.g., hydrogen or oxygen) catalytically generated in a chemical supply chamber from an appropriate chemical supply, such as a chemical solution, gas dissolved in liquid, or mixture. In some embodiments, the gas generator may employ a piston, rotating rod, or other element(s) to expose the chemical supply to the catalyst in controlled amounts. In another embodiment, the self-regulating gas generator uses bang-bang control, with the element(s) exposing a catalyst, contained within the chemical supply chamber, to the chemical supply in ON and OFF states according to a self-adjusting duty cycle, thereby generating and outputting the gas in an orientation-independent manner. The gas generator may be used to provide gas for various gas consuming devices, such as a fuel cell, torch, or oxygen respiratory devices. | 11-08-2012 |
20130209913 | NANOFIBER ELECTRODE AND METHOD OF FORMING SAME - In one aspect, a method of forming an electrode for an electrochemical device is disclosed. In one embodiment, the method includes the steps of mixing at least a first amount of a catalyst and a second amount of an ionomer or uncharged polymer to form a solution and delivering the solution into a metallic needle having a needle tip. The method further includes the steps of applying a voltage between the needle tip and a collector substrate positioned at a distance from the needle tip, and extruding the solution from the needle tip at a flow rate such as to generate electrospun fibers and deposit the generated fibers on the collector substrate to form a mat with a porous network of fibers. Each fiber in the porous network of the mat has distributed particles of the catalyst. The method also includes the step of pressing the mat onto a membrane. | 08-15-2013 |
