Abstract: The swivel joint comprises a housing holding a resilient annulus which in one embodiment sealingly engages an upper portion of a tubular head at the top of the dip tube, and an inward annular lip in the lower part of the housing swivelly supports the head from below. In another embodiment the resilient annulus in the housing serves to both seal and swivelly support the dip tube by its head.

Abstract: A mobile cart-mounted unit for cleaning and preserving turbine engines comprises pressurized reservoirs for holding the solvent, cleaner, preservative and water. Pressurization is achieved by use of an integrally mounted air compressor driven by an internal combustion engine. The engine also powers an alternator which is used to charge a storage battery. The storage battery serves as an energy source to crank the turbine to approximately 10 percent rated speed during the cleaning and preservation servicing sequence. A control console provides the operator with the needed valves, gages and meters with which to operate the unit.
