Abstract: Methods and systems for reducing a pressure of compressed natural gas and for delivering natural gas are disclosed. A regulator comprising a vortex tube may be used to reduce the pressure of compressed natural gas while a temperature thereof is also reduced. The temperature reduction associated with a pressure drop in the compressed natural gas is achieved by throttling the gas at constant enthalpy from 3,000 psig to 150 psig through the regulator. At least one heat exchanger may be utilized to increase the temperature of the compressed natural gas to a temperature suitable for injection delivery. A pressure-reducing regulator may be used to further reduce a pressure of the gas to about 45 psig for delivery to an end-user.

Abstract: Ankle prosthesis apparatuses, systems and methods are provided as disclosed herein. Additionally, systems and methods for bone resection and implantation of prosthetics are provided, including surgical techniques and related instrumentation. An ankle prosthesis apparatus can include a talar component having a lower surface with a bone fixation portion for fixation to a talus bone and an upper surface designed for articulation with a bearing component. The bearing component can have a lower surface for articulation with the talar component and an upper surface for articulation with a tibial component. The tibial component can have a lower surface for articulation with the bearing component and an upper surface with a bone fixation portion for fixation to a tibia bone and/or a fibula bone. The bearing component can have a protrusion on its upper surface adapted for engagement with a recess on the tibial component to allow desired rotational and translational movement.
