摘要： A radiation imaging system comprising a scintillator, an imager array, and a lamination layer. Lamination layer bonds and optically couples scintillator to imager array. Lamination layer is comprised of a lamination material that is substantially free from void spaces. Radiation imaging system fabrication comprises the steps of disposing lamination layer between a light imager and a scintillator to form a subassembly. Light imager comprises imager array, an imaging plate surface and a plurality of contact pads. Additional steps include subjecting subassembly to a vacuum; heating subassembly to a bonding temperature, exerting a bonding force on subassembly, maintaining the vacuum, the bonding temperature and the bonding force until light imager is bonded to the scintillator and the lamination layer is comprised of lamination material that is substantially free from void spaces.

摘要： A metering and control system is described for supplying fuel to a burner nozzle of a burner assembly which preheats intake air in a diesel engine. Fuel for the control system is derived from the regulated pressure output of a fuel pump in the engine fuel supply system. The fuel metering and control system includes a series of parallel flow lines connected between the fuel pump and the burner nozzle. Each line has a metering orifice and check valve set to pass flow above a given pressure level. For intermediate rpm flow is through one line and at high rpm flow is through both. As a result, the fuel flow rate into the burner nozzle is directly proportional to engine rpm to provide a uniform nozzle preheat temperature over the full range of engine rpm. Suitable control inputs are provided to initiate or terminate flow to the burner in response to selected engine operating parameters. In addition, supplemental fuel flow may be provided during start up and/or cold operating conditions, again initiated or terminated by selected engine operating parameters.
