Patent number: 6833032Abstract: An automatic deliming process for a steam oven cooker is described. The process initiates a deliming procedure after a predetermined time of normal operation, which period of time is determined by the hardness of the water in the local area. Upon the expiration of this period of time a microprocessor signals an operator to shut down normal operation of the oven, and initiate the deliming process. The microprocessor then activates a peristaltic pump which injects a predetermined quantity of deliming liquid from an external reservoir into the generator. After the deliming time has passed and the generator contents have cooled to 140° F. the microprocessor automatically activates a drain pump to drain the deliming solution from the generator. Subsequently the microprocessor activates a fill-solenoid opening and inlet from a reservoir of rinse water into the generator to rinse the same. The microprocessor then again opens the drain to drain the rinse water, and normal operation is resumed.Type: GrantFiled: November 5, 2002Date of Patent: December 21, 2004Assignee: Blodgett Holdings, Inc.Inventors: Scott Douglas, John Bardeau

Publication number: 20040238006Abstract: Disclosed is a novel process for interior cleaning and by cleaning, removing noxious gas and/or restoring the operating efficiency of organically contaminated hydrocarbon processing equipment in a safe and effective manner and in a very short period of time, without a need to manually enter an unsafe environment and mechanically remove organic contaminants. Used is a formulation of non-aqueous, monocyclic saturated terpene mixed with a non-ionic surfactant package. The terpene-based chemical is injected into organically contaminated equipment using a novel process involving high-pressure steam to form a very effective cleaning vapor.Type: ApplicationFiled: May 28, 2003Publication date: December 2, 2004Applicant: Refined Technologies, Inc.Inventors: Sean E. Sears, Kevin L. Roberts

Publication number: 20040168712Abstract: This invention is a method for cleaning a semiconductor manufacturing system, which passes a highly volatile liquid agent through the system to remove the impurities and to dissolve chemicals used in the system. The cleaning agent dissolves and washes the chemicals out of the system to keep the chemicals from combining with moisture in the air and forming oxide particles. By washing with a liquid, residual gases and impurities in the system are rapidly removed from the system. After washing the system, the cleaning agent is quickly dried because the cleaning agent is highly volatile. Thereby, the system is cleaned efficiently within a short time by using this method.Type: ApplicationFiled: February 26, 2004Publication date: September 2, 2004Applicant: Nanmat Technology Co., Ltd.Inventors: Wei-Sheng Chao, Chi-Hui Lin, Chuang-I Chen, Goang-Cheng Chang, Chao-Kai Hsieh, Hsin-Cheng Huang, Cheng-Jye Chu

Patent number: 6648982Abstract: Disclosed are systems and methods for removing stubborn contaminants, aluminum fluoride and aluminum chloride in particular, from components of semiconductor-processing equipment. One embodiment forces steam through small holes in a gas distribution plate to remove build up on the interior walls of the holes. A cleaning fixture disposed between the steam source and the gas distribution plate delivers the steam at increased pressures. The gas distribution plate can be immersed in water during cleaning to capture the exiting steam.Type: GrantFiled: June 11, 2001Date of Patent: November 18, 2003Assignee: Quantum Global Technologies, LLCInventors: David S. Zuck, Kurtis R. Macura

Patent number: 6598805Abstract: A gas mixture of dry steam and nitrogen gas serving as carrier gas is blown into a hot water mist injection port for rendering the nitrogen gas serve as a medium absorbing latent heat of condensation, thereby smoothly progressing condensation of water vapor and efficiently forming hot water mist. The water vapor is condensed in the hot water mist injection port formed by a cylindrical pipe for supplying latent heat of condensation to the nitrogen gas and dilating the same, thereby accelerating the flow of the hot water mist and spraying the hot water mist to a substrate from the hot water mist injection port at a high speed. Small droplets contained in the high-speed hot water mist have high kinetic energy and high thermal energy, for exhibiting a large colliding effect and a high activation effect with respect to small contaminants adhering to the substrate. A substrate cleaning apparatus capable of spraying hot water mist attaining a high cleaning effect to a substrate is provided.Type: GrantFiled: May 15, 2002Date of Patent: July 29, 2003Assignee: Dainippon Screen Mfg. Co., LTDInventors: Takamasa Sakai, Sadao Hirae

Patent number: 6408860Abstract: A method for cleaning phosphorus from a MBE vacuum chamber by freezing the panel (22) placed within the vacuum chamber (10) onto which excess phosphorus is deposited. The panel is connected to a source of cold nitrogen (24) which cools the panel. Water is introduced after the panels are cooled so as to form a layer of ice on top of the phosphorus. The panel may then be removed for cleaning with ice covering the phosphorus without danger of ignition of the phosphorus.Type: GrantFiled: September 21, 2000Date of Patent: June 25, 2002Assignee: TRW Inc.Inventors: Patrick T. Chin, Todd K. Makishi, Thomas R. Block

Patent number: 6401730Abstract: A method for cleaning small volume pharmaceutical containers of particulate contamination, which includes the simultaneous introduction of air and cleaning fluid as a moving film on the interior of the container, particulary in a neck region, to prevent re-deposit of contaminant particulates thereon. A nozzle is used for introduction of fluid such as water into the container and a tube within or otherwise juxtaposed with the nozzle is used for the simultaneous introduction of air. Cleaning is effected before initial medical application use.Type: GrantFiled: January 17, 2001Date of Patent: June 11, 2002Inventor: Julius Z. Knapp

Patent number: 6348174Abstract: Infectious wastes originating in hospitals or other locations are deposited into a sealable, pressure resistant, portable sterilizer vessel at the source of the wastes. The sterilizer vessel rides on wheels enabling travel of the filled vessel to a sterilization station at another location where steam is directed into the vessel to perform the sterilization. Operators need not transfer unprocessed infectious waste from a collection cart to a fixed sterilization vessel at the sterilization site. In the preferred form, handler exposure to unprocessed wastes is further reduced by creating an airflow from the vessel opening to a filter while the vessel is opened for deposit of wastes.Type: GrantFiled: December 6, 1999Date of Patent: February 19, 2002Inventor: John L.
