Patent number: 7931877Abstract: A device for disinfecting a portion of an implement such as a needleless hub or injection port. The device includes a body shaped to engage the implement with the portion to be disinfected exposed. A disinfectant area is located on the body so as to permit pivotal displacement of the area relative to the body such that in a first orientation the portion to be disinfected is exposed and in a second orientation the portion to be disinfected is covered and the disinfectant area engages the portion to be disinfected.Type: GrantFiled: October 23, 2007Date of Patent: April 26, 2011Assignee: Sage Products, Inc.Inventors: Jeffrey B. Steffens, Gregory T. Davis, Paul H. Hanifl

Patent number: 7931752Abstract: A method for cleaning a semiconductor equipment is provided. First, a first cleaning step is performed to the process chamber. The first cleaning step includes conducting a cleaning gas into the process chamber via a short processing gas injector for generating a plasma of the cleaning gas in the process chamber. Then, a cleaning step is performed to a long cleaning gas injector. The cleaning step performed to the long cleaning gas injector includes conducting the cleaning gas into the process chamber via the long processing gas injector. Then, a second cleaning step is performed to the process chamber. The second cleaning step includes conducting the plasma of the cleaning gas into the process chamber via the short processing gas injector.Type: GrantFiled: January 6, 2009Date of Patent: April 26, 2011Assignee: United Microelectronics Corp.Inventors: Chong-Tat Lee, Jui-Lin Tang, Chee-Thim Loh, Kok-Poh Chong

Publication number: 20110083700Abstract: A teat cup cleaning device comprises a heating chamber provided with a discharge outlet that is closable by a valve and arranged for connection to a teat cup. A filling device is arranged for filling the heating chamber with an amount of cleaning liquid and retaining a given quantity of gas. The chamber is provided with a heating arrangement arranged to heat the contents of the heating chamber to a temperature T higher than the boiling point Tk of the cleaning liquid at ambient pressure. On operation of the valve superheated cleaning liquid is discharged to clean a teat cup.Type: ApplicationFiled: December 17, 2010Publication date: April 14, 2011Applicant: MAASLAND N.V.Inventors: Karel Van Den Berg, Gerard Mostert

Publication number: 20110079241Abstract: This invention relates in part to a method for cleaning an ion source component of an ion implanter used in semiconductor and microelectronic manufacturing. The ion source component includes an ionization chamber and one or more components contained within the ionization chamber. The interior of the ionization chamber and/or the one or more components contained within the ionization chamber have at least some deposits thereon of elements contained within a dopant gas, e.g., carborane (C2B10H12). The method involves introducing a cleaning gas into the ionization chamber, and reacting the cleaning gas with the deposits under conditions sufficient to remove at least a portion of the deposits from the interior of the ionization chamber and/or from the one or more components contained within the ionization chamber.Type: ApplicationFiled: October 1, 2009Publication date: April 7, 2011Inventors: Ashwini Sinha, Serge Marius Campeau, Lloyd Anthony Brown

Publication number: 20110067730Abstract: A method for cleaning containers, in particular bottles of glass or plastics, and a cleaning machine with at least one cleaning medium, with the containers cleaned at least in one station preferential for the cleaning result and/or in a procedure step with at least essentially chemical-free cleaning media. The cleaning medium is advantageously a granular material, in particular granular ice, carried under pressure with compressed air or compressed water. The cleaning machine suited for carrying out the method includes downstream of an unpacking and presoaking station, a pre-cleaning station with a high pressure water blasting pre-cleaning section, and subsequently an intensive cleaning station with at least one intensive cleaning section to which a pressure blasting system for chemical-free, granular material and a carrier medium are associated, and a disinfection station following the intensive cleaning station.Type: ApplicationFiled: August 30, 2010Publication date: March 24, 2011Applicant: KRONES AGInventors: Cornelia Folz, Jan Momsen, Heinz Humele, Timm Kirchhoff, Klaus-Karl Wasmuht, Bernd Hansen, Thomas Islinger, Christoph Weinholzer

Patent number: 7909935Abstract: The present invention is directed to a method of cleaning an interior surface of a fluid delivery system. The method comprises introducing a first liquid into the fluid delivery system and contacting the interior surface with the first liquid; forming a slurry by introducing a particulate into the first liquid and contacting the interior surface with the slurry; introducing a second liquid into the fluid delivery system and contacting the interior surface with the second liquid; and introducing a third liquid into the fluid delivery system and contacting the interior surface with the third liquid. The first liquid is substantially soluble or substantially insoluble in the second liquid, the second liquid is substantially insoluble in the third liquid, and the particulate is substantially insoluble in the first and second liquids and substantially soluble in the third liquid.Type: GrantFiled: October 10, 2008Date of Patent: March 22, 2011Assignee: PPG Industries Ohio, Inc.Inventors: Jonathan N.
