A shock mount may be used to mount an accessory gearbox to an engine case. The shock mount may allow free thermal expansion, while providing damping and stiffness in response to vibrations. The shock mount may include a cylinder filled with fluid, and a piston telescopically moveable within the cylinder. The piston may be coupled to an orifice plate. The orifice plate may include orifices through which the fluid may flow in response to compression or extension of the shock mount. The interaction of the fluid and the orifice plate may resist rapid compression or extension of the shock mount while allowing relatively slow compression or extension of the shock mount. | 03-24-2016 |
20160090910 | Membrane Separation Of Carbon Dioxide From Natural Gas With Energy Recovery - Carbon dioxide is separated from natural gas using a single stage membrane separation system to produce a retentate gas that typically meets the specification for pipeline distribution of natural gas, and a permeate gas comprising methane that is combusted to generate power and/or heat, e.g. for use in providing the utility requirements of the process itself or for export to an integrated process. Advantages include an overall reduction in power consumption and improvement in process efficiency. | 03-31-2016 |
