Title: Edge compression manifold apparatus

Abstract

A manifold for connecting external capillaries to the inlet and/or outlet ports of a microfluidic device for high pressure applications is provided. The fluid connector for coupling at least one fluid conduit to a corresponding port of a substrate that includes: (i) a manifold comprising one or more channels extending therethrough wherein each channel is at least partially threaded, (ii) one or more threaded ferrules each defining a bore extending therethrough with each ferrule supporting a fluid conduit wherein each ferrule is threaded into a channel of the manifold, (iii) a substrate having one or more ports on its upper surface wherein the substrate is positioned below the manifold so that the one or more ports is aligned with the one or more channels of the manifold, and (iv) device to apply an axial compressive force to the substrate to couple the one or more ports of the substrate to a corresponding proximal end of a fluid conduit.

  • A manifold for connecting external capillaries to the inlet and/or outlet ports of a microfluidic device for high pressure applications is provided. The fluid connector for coupling at least one fluid conduit to a corresponding port of a substrate that includes: (i) a manifold comprising one or more channels extending therethrough wherein each channel is at least partially threaded, (ii) one or more threaded ferrules each defining a bore extending therethrough with each ferrule supporting a fluid conduit wherein each ferrule is threaded into a channel of the manifold, (iii) a substrate having one or more ports on its uppermore » surface wherein the substrate is positioned below the manifold so that the one or more ports is aligned with the one or more channels of the manifold, and (iv) device to apply an axial compressive force to the substrate to couple the one or more ports of the substrate to a corresponding proximal end of a fluid conduit.« less
  • A vertical axis hermetic compressor includes an inner cylindrical housing fixed internally of a sealed outer enclosure bearing paired helical screw rotors defining with the inner housing closed thread compressor compression chambers. An electrical drive motor overlies the rotors and is shaft connected to one of the rotors. Compressed refrigerant vapor, where refrigerant is the working fluid, discharges through the motor rotor. Centrifugal force functions as a primary oil separator for oil entrained within the working fluid. An inverted dish deflector underlies a gas discharge port axially within the top of the outer enclosure such that oil impacted by gasmore » flow discharging axially from the motor adheres to the deflector to provide secondary oil separation while the gas passes about the periphery of the deflector to escape through the discharge opening of the outer enclosure. A non-woven plastic mesh pad fixed to the bottom of the deflector acts as a shock absorber for the entrained oil to prevent re-entraining oil in the gas stream in mist form to provide tertiary oil separation thereby reducing oil mist carried by the escaping gas to less than about 0.5 percent by weight. Oil dropping from the deflector into the bottom of the outer enclosure functioning as an oil sump impacts against a two passage parallel flow dual transfer tube including one passage supplying liquid refrigerant from the condenser to the compressor working space for cooling the same through a liquid injection port and within a second passage, intermediate pressure refrigerant vapor injected into the compression process through a vapor injection port. This prevents excessive heating of the working fluid pulsing in the tubes during compression with control valves in the passages leading to the liquid injection and vapor injection ports closed.« less
