Abstract: A method and apparatus of washing laundry using a reduce amount of, or without the use of, hot water and detergents using a closed-loop or open-loop ozonated wash water system wherein wash water maintained in a contact tank is ozonated by an ozone generator prior to use in the washing machine. The oxygen and/or dried air used in the ozone generator to generate the ozone is concentrated by an oxygen concentrator before being fed into the generator. The system includes a venturi injector for entraining ozone into the water in the storage and contact tanks. The system also includes the use of contact extenders, static mixers and flow restriction fittings. The spent wash water may be collected, filtered and reused, thereby eliminating waste water disposal problems, resulting in considerable water and energy savings.

Abstract: An automatic clothes washing machine includes an outer housing, a tub mounted in the housing, and a perforated basket mounted in the tub. An ozone generator generates ozone which is conducted to water in the tub for sterilizing, bleaching and deodorizing clothes being washed. The ozone is conducted through a double-wall pipe to a perforated ozone distributor disposed between the tub and basket. The ozone generator comprises a flexible tube which is intermittently compressed by an electromagnetically controlled actuator for directing air toward an ozone-producing electrode.

Abstract: The invention concerns a method for dyeing textiles, whereby textiles are loaded with a dye liquor containing dye in diluted form; several mutually separate dye compartments (dye containers) being provided and mounted in a zone above the dyeing chamber receiving the textiles to be treated. Several textile pieces are processed simultaneously in the dyeing chamber of which the base zone comprises supply lines with upwardly directed supply apertures for steam and for the dye liquor. Thus, it possible to deposit colors structured as pictures across wide areas and differing from each other on a variety of textiles. Furthermore, uniform dye soaking of the textiles is achieved in spite of such image designs. For that purpose, the invention provides that the dye liquor is made to pass from below to above through the textiles using pressurized transport media at raised pressure.

Abstract: This invention relates to a method and apparatus for liquid deflection for liquid spray generators utilized in impressing marking materials (e.g., dyes, inks, paints, coatings) onto substrates (e.g., fabric) and, more particularly, to a mechanism for producing a plurality of aligned streams of atomized droplets to produce a pattern on a substrate. A constant air supply is utilized with a liquid marking material line which is low enough to prevent diverting of the stable liquid stream but high enough to keep the air orifice free of liquid. Shields are also utilized to prevent the liquid mist accumulation from accidently getting on the substrate to be treated.

Abstract: In a unified washing-drying machine, the use of conventional drying means is eliminated and, instead, an electromagnetic heating system is provided at an appropriate place in the unified washing-drying machine as a means to thermally evaporate the remaining moisture in the washed fabrics during the drying cycle. A high-pressure air system with the air nozzle assemblies imbedded on the agitator is installed in the unified washing-drying machine such that the high-pressure air flow from the air nozzle assemblies can float the washed fabrics to have the evaporated steam or water vapor removed efficiently. Also, the high-pressure air flow can have the washed fabrics circulate and tumble well to prevent wrinckles from setting on the washed fabrics. Thus, with the invented unified washing-drying machine contineous, uninterrupted cleaning and drying cycles can be achieved with the additional benefit of saving space by eliminating an extra dryer installment as in a conventional laundry system.

Abstract: A unit for automatically cleaning items such as laundry or the like comprises a plurality of reciprocating plungers mounted to engage the items within a tank containing the items and a cleaning liquid. Each plunger comprises a piston mounted within a canister. The piston is mounted within the canister in an arrangement which permits a limited relative movement between the piston and canister, thus developing a bi-directional pumping action. With each stroke of the plunger, the piston forces liquid through the items to be cleaned, first in one direction and then the other, by virtue of the limited movement of the piston relative to the canister, the latter serving to assist in holding the items to be cleaned in a position for encountering the liquid being driven by the piston. The combined rotary reciprocating action of the plungers not only serves to clean the items in the tank but also to slowly propel them from the inlet to the outlet end of the tank so that a continuous cleaning process is performed.
