    Abstract: A cleaning chamber and a separate spaced-apart drying chamber are provided, which communicate with one another. Articles are cleaned in the cleaning chamber while the same is out of communication with the drying chamber. Then the communication between the chambers are established and the cleaned articles are transported from the cleaning chamber into the drying chamber with a stream of air circulating in a closed path. After this, the communication between the chambers is interrupted and the thus-transported articles are dried in the drying chamber. A transport conduit communicates the chambers with one another, and a flap located in the former is operative for closing and opening the transport conduit. An air passage additionally communicates the chambers with one another, and an air impeller causes air to travel into the cleaning chamber to thereby transport the articles from the same, and to travel into the drying chamber to thereby dry the articles.

    Abstract: A method for cleaning greatly soiled textiles with organic solvents and aqueous detergent solutions consisting essentially of (1) contacting greatly soiled textiles with a cleaning liquor consisting of a customary water-immiscible, organic dry-cleaning solvent and an aqueous solution of a detergent composition containing from 3.5% to 35% by weight of said solution of an anionic surface-active compound with a low solubility in said organic dry-cleaning solvent, wherein from 0.5 to 10 gm of said detergent composition are present per liter of said cleaning liquor for a time sufficient to clean said soiled textiles and to have said textiles absorb said aqueous solution, (2) removing the soiled organic dry-cleaning solvent from said textiles containing absorbed aqueous solution, (3) contacting said textiles containing absorbed aqueous solution with water for a time sufficient to completely wash said textiles, (4) rinsing said textiles with water, and (5) recovering said cleaned textiles.

    Abstract: A method of dry cleaning of goods in which the majority of the solvent present in the goods at the conclusion of the actual cleaning is recovered by circulating air, by means of a fan, through the goods in a dry cleaning drum and through a watercooled condenser and a heating element, and then a small remaining amount of solvent is removed from the goods by a deodorizing operation, in which air is passed in a closed circuit through the goods in the dry cleaning drum and over a refrigerated surface on which the solvent is condensed.

    Abstract: Low-boiling solvent is circulated in a dry cleaning apparatus during cleaning from a cleaning tank through a filter to a storage tank and back to the cleaning tank. Mechanical refrigeration units control the temperature and pressure in the apparatus by drawing solvent vapors from the tanks and returning cold liquid solvent to the storage tank. One of the units also condenses the solvent vapors driven out of the cleaned objects by heating after the cleaning step, and makes a vent unnecessary.
