Patent number: 7670462Abstract: A system and method whereby on-line cleaning of black oil heater tubes and delayed coker heater tubes may be effectuated by injecting a high pressure water charge through the tubes during normal process operations so as to prevent tube fouling and heater downtime. The high pressure water charge begins the on-line cleaning process once it enters the heater tube by undergoing intense boiling and evaporation. The cleaning occurs by two methods—a scrubbing action and a shocking action. The scrubbing action occurs because of the complete turbulence caused by the water charge's intense boiling within the heater tubes. The shocking action is caused by the expansion and contraction of the heater tubes resulting from the colder water charge flowing through the heater tubes which is then followed by the hotter process fluid flowing through the heater tubes.Type: GrantFiled: April 13, 2006Date of Patent: March 2, 2010Assignee: Great Southern Independent L.L.C.Inventors: William C.

By using driving device, the rotation module can be wholly driven. Also, multiple wash-heads can rotate individually along a cleaning path for cleaning wafer. The fluid was jetted from nozzle and assistant to clean wafer through fluid pipe. The prior art of single wafer wash-head is easily to reform a cleaning dead angle in wafer cleaning process.Type: GrantFiled: September 5, 2003Date of Patent: August 7, 2007Assignee: Nan Ya Technology CorporationInventors: Chih-Kun Chen, Yao-Hsiung Kung

Patent number: 7252100Abstract: A circuit board processing system includes a wash tank configured to contain cleaning fluid, and a positioning subsystem configured to immerse a set of circuit boards into the wash tank. The system further includes a flow control subsystem having (i) a first set of nozzles disposed within the wash tank, (ii) a second set of nozzles disposed within the wash tank, and (iii) a controller. The controller is configured to direct the cleaning fluid through the first set of nozzles to provide a flow of the cleaning fluid in a first direction relative to the set of circuit boards. The controller is further configured to direct the cleaning fluid through a second set of nozzles to provide a flow of the cleaning fluid in a second direction relative to the set of circuit boards after providing the flow of the cleaning fluid in the first direction.Type: GrantFiled: March 28, 2003Date of Patent: August 7, 2007Assignee: EMC CorporationInventors: Stuart D. Downes, Deborah Fragoza, Eric Ren, Thomas E. Knight

Patent number: 7188632Abstract: A high pressure water stream (14) is discharged onto a surface to be cleaned. An ozone/water stream (16) is discharged on the same surface for sanitizing the surface. The high pressure water and ozone/water streams (14, 16) are discharged simultaneously along closely adjacent paths that are either parallel (FIG. 3) or concentric (FIG. 2). The water pressure is at least about 100 p.s.i. and is preferably between 100 p.s.i. and 1000 p.s.i. The nozzles that discharge the streams (14, 16) may be movable relative to the object(s) that receives the high pressure water and ozone/water (FIG. 1) Or, they may be fixed and the object may be movable relative to them (FIG. 4).Type: GrantFiled: September 15, 2005Date of Patent: March 13, 2007Assignee: Ozone International LLCInventor: Daniel W. Lynn

Patent number: 7185664Abstract: A dish-cleaning appliance comprising a sink having a bowl defining a wash chamber with an open top for providing access to the wash chamber. A liquid recirculation system is provided for spraying liquid throughout the wash chamber. A drain conduit can be provided, alone or in combination with the recirculation system, for draining liquid from the wash chamber when the drain is closed. A fill control system is provided to ensure that the dishwashing cycle is not started with liquid in the wash chamber and that the sink drain is properly closed. One or more sensors can be provided for enabling the fill control system. The sensors can be located within the drain above the location where the drain is plugged.Type: GrantFiled: February 15, 2006Date of Patent: March 6, 2007Assignee: Whirlpool CorporationInventors: Ralph E. Christman, Ryan K. Roth

Patent number: 6983755Abstract: A cleaning apparatus includes upper and lower nozzle assemblies supplying a cleaning liquid to edge and bottom sections of a semiconductor substrate. The upper nozzle assembly has a first nozzle supplying the cleaning liquid onto the edge section, and second and third nozzles supplying a nitrogen gas for preventing the cleaning liquid from moving into a center portion of the semiconductor substrate. The cleaning liquid supplied to the edge section flows from the edge section towards a side section of the semiconductor substrate due to the rotation of the semiconductor substrate. An ultrasonic wave generator is provided above the edge section for generating ultrasonic waves. The ultrasonic waves are applied to the cleaning liquid supplied onto the edge and bottom sections, thereby improving the cleaning efficiency. The cleaning apparatus has a guide to guide the cleaning liquid supplied to the edge section toward the side section.Type: GrantFiled: October 28, 2002Date of Patent: January 10, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Chang-Hyeon Nam, Hong-Seong Son, Kyung-Hyun Kim
