| 20080308126 | INSTALLATION FOR WASHING HAND TRUCKS OF OPERATING MACHINES, PARTICULARLY HAND TRUCKS OR ROTOGRAVURE MACHINES - An installation for washing hand trucks of operating machines, particularly of rotogravure machines, is constructed and designed in order to receive and to treat in a wash chamber a whole hand truck along with all its parts, not dismounted. In the wash chamber of the installation there is a number of tubular bored bars which receive the wash solvent from a circulation pump and direct the same in the form of jets against the parts of the treated hand truck which require to be washed. The bars form a rotatable whole, are displaced in rotation and in translation in an alternate movement by pneumatic cylinders, and advantageously they surround a print cylinder mounted in the hand truck. A lower collecting basin receives the falling used solvent, and therefrom the solvent is sucked by the circulation pump during a first pre-wash step. | 12-18-2008 |
| 20110023908 | METHODS AND APPARATUS FOR PROCESS ABATEMENT WITH RECOVERY AND REUSE OF ABATEMENT EFFLUENT - Methods and apparatus for recovering hydrogen fluoride (HF) are provided herein. In some embodiments, an apparatus includes a system for processing substrates, including a process chamber for processing a substrate; a fluorine generator coupled to the process chamber to provide fluorine (F | 02-03-2011 |
| 20110088722 | CLEANING COMPOSITIONS FOR USE IN CLOSED LOOP CLEANING MACHINES - Embodiments of the present disclosure include cleaning processes, closed loop cleaning machines, and methods of cleaning an article. The cleaning process includes contacting a surface of an article with a cleaning composition in a cleaning chamber, where the cleaning composition includes at least about 85 percent by weight organic solvents, based on total weight of the cleaning composition, and where at least about 5 percent by weight of the organic solvents is propylene glycol, based on total weight of the organic solvents, to clean the surface of the article, collecting the cleaning composition including contaminants, and recovering the cleaning composition via distillation, where a distillation apparatus removes the contaminants from the cleaning composition and is connected to the cleaning chamber by a process stream. | 04-21-2011 |
| 20110186079 | Method of Operation for a Recycler Assembly - A method of operating an assembly for recycling a solvent from a contaminated solvent solution including a source for the contaminated solvent solution at a level and a recycling assembly including a reservoir module and a recycler module. The reservoir module includes a reservoir and the recycler module includes a controller and a distillation assembly including a distiller having a conduit and a pressure relief valve. The pressure relief valve includes a tube. The method includes connecting the conduit to the source below the level; connecting the pressure relief valve tube to the source; pumping solvent into the reservoir, distiller and conduit to an operational level; and selecting a duty cycle of the controller to regulate a rest period after the controller operation of a distillation cycle. | 08-04-2011 |
| 20110186080 | Method of Service for a Recycler Assembly - A method of servicing an assembly for recycling a solvent from a contaminated solvent solution, the assembly includes a recycler module including a controller, a distillation assembly including a distiller, a condenser and a conduit, and an air handler assembly, and a reservoir module including a reservoir having a lid and a valve connected to the distiller. The method includes activating a service mode in the controller, actuating the valve from a recycle orientation to a service orientation, removing collected contaminants from the reservoir, and pumping solvent into the reservoir, distiller and conduit. | 08-04-2011 |
| 20110277790 | PROCESS FOR REMOVING WATER - To provide a process for removing water, which is free from formation of stains due to transfer of an article among dipping sumps, with which the water removal performance will not be decreased even for an article having a complicated shape, which can suppress suspension of water in a water removal solvent in a dipping sump, and which can maintain stable water removal performance continuously for a long period of time only with one dipping sump. | 11-17-2011 |
| 20130233350 | METHOD AND SYSTEM FOR REMOVING HYDROCARBON DEPOSITS FROM HEAT EXCHANGER TUBE BUNDLES - A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent. After contact with a heat exchanger tube bundle, the contaminated organic solvent may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The treatment of the heat exchanger tube bundle is also preferably performed using a method and system by which, through contact of the heat exchanger tube bundle with an organic solvent, a large percentage of hydrocarbon deposits are removed from the heat exchanger tube bundle in a short period of time. | 09-12-2013 |
| 20140083458 | PHOTORESIST STRIPPING SOLUTION, STRIPPING SOLUTION RECYCLING SYSTEM AND OPERATING METHOD, AND METHOD FOR RECYCLING STRIPPING SOLUTION - Provided is a stripping solution recycling system using a photoresist stripping solution that strips a photoresist without damaging a Cu film or reducing the adhesiveness to a layer deposited on the Cu film, when a Cu film or Cu alloy film on a large-area substrate is wet-etched to make wiring or the like. The stripping solution recycling system has a resist stripping device for repeatedly using a stripping solution; a distillation and regeneration device for distilling the stripping solution in the waste tank; a component analyzer for investigating the composition ratio of the main agent and the polar solvent in the separated liquid; a preparation device for preparing the mixed solution; and a supply tank for storing the mixed solution. | 03-27-2014 |
| 20150369424 | PROCESSING SYSTEM - A system for processing objects to be cleaned that includes a processing vessel, and a storage vessel that includes an upper section for storing clean liquid and a lower section for storing dirty liquid. The upper section and lower section are in flow communication. | 12-24-2015 |
