Abstract: A parts washing system comprises a wash liquid holding tank having a return opening, a rinse liquid holding tank also having a return opening, a wash chamber with drain port situated above both the wash liquid holding tank and the rinse liquid holding tank, a parts carrier movable from a loading position outside the wash chamber to a position inside the wash chamber, a nozzle adapted to direct liquid from one of the holding tanks into the wash chamber, at least one pump for transferring wash liquid and rinse liquid from the wash liquid holding tank and the rinse liquid holding tank to the spray nozzle, and a substantially L-shaped liquid diverter. The L-shaped liquid diverter is rotatably mounted at the drain port of the wash chamber for rotation in a substantially vertical plane. The L-shaped liquid diverter has an outlet end for dispensing liquid from the wash chamber to one of the wash liquid holding tank and the rinse liquid holding tank.

Abstract: Drive mechanism suitable for a parts treating machine comprises a housing defining a chamber containing a rotatable carriage wheel with a fixture journalled for rotation thereon. A carriage wheel drive is provided for indexing the carriage wheel and a fixture drive for rotating fixtures carried by the carriage wheel at a predetermined position. The carriage wheel drive includes a motor and a gear reducer operatively connected to the carriage wheel. The fixture drive includes a motor and a gear reducer operatively connected to a gear on a shaft extending upwardly from the fixture by an endless belt. The carriage wheel may be moved from a load station to a treating station, where spray nozzles or the like may spray treating material onto the parts to be treated as they are rotated together with the fixture at the treating station.

Abstract: A parts cleaning machine comprises a housing having a wheel with a fixture journalled for rotation thereon. The wheel comprises one or more pockets within which the fixtures may rotate. Drive mechanism comprising a wheel drive for indexing the wheel and a fixture drive for rotating the fixture at a predetermined location or locations during indexing of the wheel is provided in the housing. The wheel drive is actuated by a motor and a gear reducer operatively connected to the pocketed wheel. The fixture drive is actuated by a motor and an endless belt, or the like, is operatively connected to a drive gear on a shaft extending upwardly from the fixture. The wheel may be moved from a load station to a wash station, where spray nozzles may spray wash liquid onto the parts to be cleaned as they are rotated in the fixture at the wash station.

Abstract: An improved filtration system comprises a vessel divided into a concentrate chamber and a permeate chamber by a permeable septum. An ultrasonic wave generator is mounted to the vessel and positioned to direct ultrasonic waves through both the permeate contained in the permeate chamber and the permeable septum. A circulator such as a pump or agitator is operably associated with the concentrate chamber to provide a shearing force on the surface of the permeable septum. A vessel inlet port allows concentrate to flow into the concentrate chamber and a permeate outlet port allows permeate to be withdrawn.
