Abstract: A high-speed switching power supply. The high-speed switching power supply includes a primary power supply. A plurality of switching elements are connected to the primary power supply. A plurality of coils is connected to the plurality of switching elements. A capacitor is connected to the plurality of coils. A sum of currents flowing through the plurality of coils is made constant by a means for setting or selecting a power supply voltage depending on the number of coils.

Abstract: A dryer for drying textiles is disclosed. The dryer includes a blower for blowing air under the carpet, which includes a blower housing including a sleeve that forms an air outlet opening and a powered fan within the blower housing for blowing air out of the outlet opening. A tow handle is located on the blower housing above the fan and an indentation is included in the underside surface of the blower housing. The indentation has a shape corresponding to the shape of the tow handle such that the indentation can receive a tow handle from a second dryer to allow stacking of dryers. A maneuvering handle is rotatably connected at a first end to the tow handle. The maneuvering handle extends over the blower housing such that a foot located at the second end of the maneuvering handle rests on the upper surface of the blower housing sleeve.

Abstract: A mobile rug or carpet cleaner is provided with a support housing having front and rear wheels mounted so that the unit is tilted about the housing axis of the front wheels to engage and disengage a cleaning head with the carpet to be cleaned. The cleaner includes a fluid delivery system which provides fluid flow to the cleaning head, an auxiliary cleaning head and a spotter. The fluid delivery system utilizes a pump having an open conduit which continuously recycles cleaning fluid to a reservoir. The continuous recycle allows a solenoid valve in a line transporting fluid to the cleaning head spray nozzles to be abruptly closed without subjecting the entire fluid delivery system to a sudden, potentially damaging increase in fluid pressure. An automatic drain system utilizes a vacuum line to direct spent cleaning fluid to a removable waste tank for disposal. Suction can be selectively directed to the cleaning head or to the auxiliary head.
