    摘要： A PORTABLE RUG SCRUBBING UNIT HAVING SCRUBBING, FOAM GENERATING AND VACUUMING ASSEMBLIES INCORPORATED DIRECTLY THEREIN. THE DRIVING MOTOR HAS AN ELONGATED SHAFT UPON WHICH ARE MOUNTED A VACUUM IMPELLER ASSEMBLY, A PRESSURE IMPELLER ASSEMBLY AND A PULLEY FOR DRIVING THE CYLINDRICAL SCRUBBING BRUSHES. THE BRUSHES ROTATE IN OPPOSITE DIRECTIONS VIA A GEAR TRAIN AND BY SELECTIVELY SHIFTING THE HANDLE, THE OPERATOR MAY SHIFT THE WEIGHT OF THE DEVICE FROM ONE TO THE OTHER OF THE BRUSHES, THUS TENDING TO MOVE THE MACHINE REARWARLY OR FORWARDLY. LIQUID DETERGENT IS SUPPLIED TO A FORMER ASSEMBLY LOCATED ADJACENT THE BRUSHES. THE FOAMER ASSEMBLY MIXES PRESCRIBED AMOUNTS OF DETERGENT AND AIR CAUSING IT TO EMIT THEREFROM ONTO THE BRUSHES IN THE FORM OF DRY FOAM WHICH, WHEN WORKED INTO THE CARPET BY THE SCRUBBERS, SUSPENDS DIRT AND OTHER FOREIGN PARTICLES THEREIN. THE VACUUM SQUEEGEE IS POSITIONED FORWARDLY OF THE BRUSHES, PERMITTING THE OPERATOR TO SCRUB DURING FORWARD MOTION OF THE MACHINE AND VACUUM FINALLY DURING THE REARWARD MOTION OF THE MACHINE. SUITABLE VALVES ARE PROVIDED, OF COURSE, FOR DEACTIVATING THE FOAMER DURING ANY DESIRED PERIOD. THE FOAM AND PARTICLES SUSPENDED THEREIN ARE TRANSFERRED VIA THE SUCTION IMPELLER TO A SUITABLE RECEPTACLE POSITIONED ON THE HANDLE OF THE MACHINE. IT IS UNDERSTOOD THAT THIS ABSTRACT IS NOT TO BE UTILIZED TO LIMIT THE SCOPE OF THIS INVENTION.

    摘要： A FUEL CELL BATTERY HAVING A PLURALITY OF UNITIZED DUPLEX FUEL CELLS, EACH BEING COMPRISED OF CONVENTIONAL FUEL CELL ELEMENTS. THE UNITIZED DUPLEX CELLS ARE MOUNTED IN THE BATTERY SUCH THAT EACH CELL OPERATES INDEPENDENTLY OF ALL OTHER CELLS IN THE BATTERY. A FLUID CIRCULATES INSIDE EACH DUPLEX CELL AND A FLUID REACTANT CIRCULATES BETWEEN ADJACENT DUPLEX CELLS, THEREBY PERMITTING EACH CELL TO BE REMOVED FOR REPAIR OF REPLACEMENT WITHOUT THE DISASSEMBLY OF THE ENTIRE BATTERY.
