Abstract: In a vertical hermetic compressor, an inner cylindrical housing coaxially mounted within a sealed outer enclosure, sealably carries at its lower end, paired helical screw rotors defining with the inner housing a screw compressor compression chamber and supports coaxially with one of the screw rotors and constituting an axial extension thereof the compressor electrical drive motor by longitudinally spaced tapered roller bearings. Oil is bled from the sump and fed to the suction inlet tube to the compressor upstream of the working gas filter. Compressed working fluid is discharged axially downwardly with the lower tapered roller bearing assembly providing a minimal high pressure gap between the screw rotor ends and the stationary end plates. Entrained oil from the discharge passage which extends through the electric motor rotor seeks the suction side of the compressor through the upper of the two tapered roller bearing pack assemblies for controlled continuous lubrication of the upper bearing assembly.

Abstract: After rugs have been cleaned in place in dwellings using liquids, even though the cleaning operations involve the vacuuming of then dirty cleaning liquids from the rug, considerable moisture is left in the rugs. To remove this residual moisture this rug dryer is centered over a large rug area. Then during drying operations the dryer blower fan draws room air in from above and directs the room air downwardly toward the rug for distribution along the floor and through the rug fibers in multiple directions away from the fan, while being directionally controlled near the rug, below a continuous floating and fluttering layer of an air impervious material extended over a large area of the rug. In a preferred embodiment, the axis of the dryer blower fan is arranged vertically and the fan housing of the blower assembly is mounted above the rug on small diameter legs. Also the fan housing of the blower assembly has a spaced outer ring to which the air impervious material is attached.
