Processes and apparatuses for commercial and home-use cleaning of textile. Home-use embodiments replace the home laundry clothes dryer, except for embodiments using a novel manual kit. Home-use embodiments have an integrated spotting station. Soiled / stained textile is spray dampened with solvent, preferably automatically in the apparatus' rotatable drum; but the textile is not soaked nor immersed in solvent. Highly absorbent, untreated pad material is placed into the drum, for rubbing against the tumbling textile, to remove the soil, stains and solvent.

An apparatus and a method for treating, cleaning or refreshing fabric articles. Specifically, the apparatus is dual mode apparatus capable of both washing and drying operations wherein a lipophilic fluid is used in at least one step of the fabric treatment process in the apparatus. A kit containing replaceable / consumable components is also provided.

A method of revitalizing a fabric comprises directing a flow of air through a chamber while tumbling the fabric to dehydrate the fabric; removing particulates from the air flowing through the chamber; directing a treatment fluid into the chamber and onto the fabric; and tumbling the fabric while at least intermittently contacting the fabric with a low absorbency textured surface. In another embodiment, a method comprises placing the fabric in a chamber having a low absorbency textured surface; extracting fluid from the fabric to dehydrate the fabric; inserting treatment fluid into the chamber to apply the treatment fluid to the fabric; and extracting fluid from the fabric to dehydrate the fabric.

The present invention relates to an apparatus for treating, refreshing or cleaning fabric articles, especially articles of clothing, linen and drapery.

The invention relates to a non-aqueous washing machine, methods of using the machine, methods of washing, and recycling and modular components and subsystems thereof.

This invention relates to a fluid driven agitator used in densified gas cleaning system, which comprises a hydraulic motor mounted to a cleaning vessel of the densified gas cleaning system, wherein the hydraulic motor comprises a fluid in-port for charging the fluid into the hydraulic motor from outside of the cleaning vessel, and a fluid out-port for discharging the fluid from the hydraulic motor out of the cleaning vessel. An output shaft of the hydraulic motor can be joined to a rotatable component, such as a rotary basket or an impeller, subjecting circulation of the fluid and resulting in stirring.

A device for cleaning textile articles with a densified liquid state treatment gas, comprising a treatment chamber (10), a supply tank (18) for densified treatment gas and an evaporator chamber (36), which spaces are connected to each other by way of suitable tubes to allow pressure balance between the different spaces, filling of the treatment chamber (10) with liquid state treatment gas from the supply tank (18), as well as drainage of liquid state treatment gas from the treatment chamber (10) to the evaporator chamber (36). Compressor means (46) are arranged which are organized partly to achieve essentially complete drainage of gaseous treatment gas from the treatment chamber (10), and partly constitute the driving means during one in the treatment process included distillation phase, where densified treatment gas in the evaporator chamber (36) is gasified and through condenser means (44) conveyed back to the supply tank (18). The condenser means are in heat conducting touch with the evaporator chamber (36), and form together with the compressor means (46) a heat pump, which alone furnish the necessary heat energy for evaporating the liquid in the evaporator chamber (36). In a modified embodiment the treatment chamber (10) is adapted so as to act also as an evaporation chamber.

A method for fluid recovery in a semi-aqueous wash process including the steps of receiving semi-aqueous wash liquor from a wash container; pretreating the semi-aqueous wash liquor and separating it into aqueous-rich working fluid phase and non-aqueous working fluid phase, treating the aqueous-rich working fluid phase to remove remaining non-aqueous working fluid, and treating the non-aqueous-rich working fluid phase for recovery and reuse.

The present invention provides a method and a device, by which it is possible to decompose and treat a large amount of organic halogen compounds, etc. which are environmental pollutants, to a low concentration range at which it is dischargeable as waste liquor to sewage in a short time, and it is also possible to decompose organic substances and nitrogen or phosphorus compounds which are hardly decomposable by oxidation. To a sample solution 20 contained in a reaction vessel 10a in which an aqueous solution containing environmental pollutants is stored, for example, ultrasonic waves 50 are irradiated from a transducer 30a disposed at the central bottom portion of the reaction vessel 10a, and at the same time, ultraviolet rays are irradiated from an ultraviolet lamp 40a disposed at the peripheral edge of the reaction vessel 10a. In this instance, the ultraviolet lamp 40a is disposed at a position such that it does not interfere with the path of travel of ultrasonic waves 50.

An improved solvent recovery process for use in a dry cleaning method uses selective cleaning of a predetermined solvent fraction.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

A process for regenerating a solvent from a waste extract after use in a remediation process includes monitoring the water content and the amount of organic contaminants in the extract. If the water content in the extract is above a predetermined threshold value, the extract is distilled to yield the solvent therefrom for reuse in the remediation process. If the water content is below the threshold value but the amount of organic contaminants is above a predetermined limit, the extract is also distilled to yield the solvent therefrom for reuse. If the water content and amount of organic contaminants are both below their respective predetermined parameters, the extract is filtered through a molecular sieve to yield the solvent therefrom. The yield solvent is then collected from the distillation and filtering processes, and the regenerated solvent is then reused in the remediation process.

The present invention provides a washing apparatus and control method thereof, by which laundry can be dry-cleaned through the loaded configurations of the wet pad cloth, the filth transfer cloth, the steam providing unit, the fragrance spraying unit, and the detergent supplying unit using either the wet pad cloth or the filth transfer cloth or without using both of the wet pad cloth and the filth transfer cloth.
