    摘要: A method and apparatus for determining refrigerant density and mass flow rate, and for pressurizing a refrigerant recovery tank while the refrigeration system is being recharged. The mass of a flowing refrigerant is automatically continually determined by reliable static means in a controlled recharging process. Flow-dependent pressure, such as the pressure drop across the orifice, and temperature data are taken from the recharging system and are connected to a data processor which uses the pressure and temperature data to determine the refrigerant density and the mass of the flowing refrigerant that has been used. The pressure of a source of recharging refrigerant can be maintained by withdrawing and heating liquid refrigerant and returning the resulting superheated vapor directly to the source of recharging refrigerant, and recharging operations can proceed during such pressure maintenance.

    摘要: A metal alloy feedstock and method for metal injection molding is disclosed. The alloy includes at least two components, such as a first component and a second component. The first component has a first melting point and the second component has a second melting point higher than the first melting point. The first melting point and the second melting point match to the temperature gradient of the heated barrel of an injection molding machine whereby when fed into the injection molding machine the first component melts prior to the second component melts and enables the second component to solute into the first component. Additional components may also be used.

    摘要: A net-shape molded elastomeric gasket for dissipating heat and providing electro-magnetic interference (EMI) shielding for an electronic device is formed by loading a base elastomeric matrix material with thermally conductive filler and EMI reflective metallic filler and injecting the mixture into a mold cavity. The gasket of the present invention provides superior sealing between the case sections of an electronic device by shielding the device from EMI infiltration along the seam between the sections. In addition, the gasket of the present invention is in thermal communication with the case sections of the electronic device to provide thermal transfer and dissipation between the separate parts of the device.
