PrimaryExaminer-PhilipR.Coe Attorney,Agent,orFirm-Majestic,Parsons,Siebert& Hsue [57] ABSTRACT A drycleaningsystemparticularlysuitedforemploying Supercritical CO2 as the cleaning fluid consisting of a scalable cleaning vessel containing a rotatable drum adapted for holding soiled substrate, a cleaning ?uid storage vessel, and a gas vaporizer vessel for recycling used cleaning fluid is provided. The drum is magneti cally coupled to a motor so that itan be rotated during the cleaning process. The system isadapted for automa tion which permits increased energy ef?ciency as the heating and cooling effect associated with CO2 gas condensation and expansion can be channeled to heat and cool various parts of the system. 10 Claims, 3 Drawing Sheets 23 [56] 68/18 F; 134/951; 34/26, 32, 36, 72, 74 References Cited U.S. PATENT DOCUMENTS 3,969,196 7/1976 Zosel . 4,012,194 3/1977 Maffei . 4,219,333 8/1980 Harris . 5,013,366 5/1991 Jacksoneta1.. 5,123,176 6/1992 Yamadaeta1...34/32 FOREIGN PATENT DOCUMENTS 0518653Al 12/1992 European Pat.

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
