    Abstract: A commercial dry-cleaning solvent filter apparatus is configured to filter and decontaminate a used dry-cleaning solvent in a specialized multi-level filtration container to enable environmentally-friendly reuse of the used dry-cleaning solvent in a commercial dry-cleaning machine after a novel decontamination process. The commercial dry-cleaning solvent filter apparatus incorporates multi-level gravity feed filtration chambers filled with a unique multi-metallic and multi-chemical filtration “clay” agent in multiple stages for comprehensive decontamination of the used dry-cleaning solvent. The filtered and decontaminated used dry-cleaning solvent is reusable and can be pumped back into a dry-cleaning solvent tank internal to the commercial dry-cleaning machine. The reuse of the dry-cleaning solvent reduces the need for frequent solvent replacements. The movement of the used dry-cleaning solvent into or out of the commercial dry-cleaning machine and the commercial dry-cleaning solvent filter apparatus is further assisted by a motorized pump mobilizing the used dry-cleaning solvent.

    Abstract: According to the present invention, a dry cleaning washer and a dryer are arranged in a closed cycle system so that the effluent solvent vapor from the washer is delivered to an accumulator chamber generally simultaneously with the delivery from the dryer of effluent hot air. The hot air super heats the solvent vapor increasing its volitization and the heated and highly volatile solvent vapors are then passed to a condenser which includes the feed coils for supplying clean air to the dryer. In passing through the condenser, the super heated solvent vapor, instantly liquifies giving off its heat to the cool air, thus preheating the clean air prior to its entry into the dryer. The liquified solvent is returned to the washer, or to a storage reservoir.

    Abstract: The present invention relates to a process of fabric cleaning utilizing a solvent emulsion which effectively combines the dissolving and suspending power of water for hydrophilic substances with the dissolving power of organic compositions for hydrophobic substances. The factor lending economic practicability to the process is the breaking of the emulsion after it has performed its cleaning function whereby only the organic fraction thereof undergoes distillation cleansing.
