  • Patent number: 8347643
    Abstract: Various control methods are disclosed for removing moisture from the external surfaces of an evaporator in a refrigerant system to avoid moisture entering a conditioned space. In one embodiment, the evaporator fan is driven in a reverse direction, and the air is guided to the outdoor environment. In other embodiments, a supplemental exhaust fan is utilized in conjunction with the evaporator fan. Also, a reheat circuit, hot gas bypass circuit, or specific features of a heat pump unit may be utilized to more efficiently perform the moisture removal.

  • Patent number: 8348801
    Abstract: An electronic differential lock assembly includes a shift collar that is movable in response to an electronic signal from an unlocked position where axle shaft speed differentiation under predetermined conditions is permitted to a locked position where a pair of axle shafts are fixed for rotation together. Speed differentiation is provided by a differential that includes a differential gear assembly supported within a differential case. A coil surrounds the shift collar and is selectively energized to move the shift collar from the unlocked position to the locked position. The shift collar is splined to one of the axle shafts and is selectively splined to the differential case to lock the axle shafts together. The electronic differential lock assembly includes a return spring that automatically disengages the shift collar from the differential case once the coil is no longer energized.

  • Patent number: 8347647
    Abstract: An ECS system provides an ACM which locates the compressor upon a common shaft between a first turbine and a second turbine. Each RAF is located remote from the ACM such that the turbines are located outboard on each end of the ACM to provide the highest efficiency possible with each turbine using a straight axial outlet diffuser. As the compressor is located between the turbines the bypass circuits from the turbines are less circuitous and more efficient. Integral valve ports formed into the ACM housing portions results in a weight reduced design due to increase bypass efficiencies and simplified installations.

  • Patent number: 8343591
    Abstract: A method for use with a coating process includes depositing a ceramic coating on a substrate within a coating chamber. Prior to depositing the ceramic coating, an electron beam source is used to heat a ceramic material. The ceramic material radiates heat to heat a substrate to an oxidation temperature to form an oxide layer on the substrate. A desired evaporation rate of the ceramic material is established during the heating to thereby provide an improved ceramic coating.

  • Patent number: 8341934
    Abstract: An InfraRed Suppression System (IRSS) includes a double-walled exhaust duct and double walled septum. The double walled structure provides a flow path for secondary (non-exhaust gas) cooling air flow to slots along the surfaces exposed to exhaust gases. Exhaust gas flow past these slots draws cooling air across the duct and septum surfaces. This flow cools the surfaces close to the slots and mixes with exhaust gasses downstream to cool the exhaust plume. The septum in the shape of a helix rotating 360° fully blocks line-of-sight to the turbine exit from the aft of the aircraft. The exhaust duct is intended to be shrouded by an aerodynamic fairing which provides an aerodynamic contour which minimizes aerodynamic impact on the aircraft.
