Patent number: 6725570Abstract: A clothes dryer having a fire protection system. The clothes dryer chamber has an inlet which receives drying air and an exhaust for removing moisture laden air. The temperature within the drying chamber is monitored, and a determination is made from the dryer electronic controller whether or not a fire exists in the tumbler. The fire detection conditions are based on determining whether a certain temperature rise exists within the tumbler when the drying air ceases. The fire suppression system when activated will inject a fire suppressing substance into the tumbler for suppressing the fire.Type: GrantFiled: November 29, 2002Date of Patent: April 27, 2004Assignee: American Dryer CorporationInventors: Michael W. Confoey, Dennis Slutsky

Patent number: 6694638Abstract: A vent check strip for checking a dryer or a vent pipe connected to a dryer. The vent check strip has a temperature sensitive area that changes its color at a threshold temperature within a working temperature range of the dryer when the dryer functions normally. The vent check strip can be placed inside the dryer or the vent pipe so that after the dryer is turned on to perform its normal drying function for a period of time until the dryer reaches the working temperature range, the vent check strip can be retrieved for examination. If the vent check strip does not change its color, then it indicates that the dryer is malfunction or the vent pipe is clogged, kinked, broken or otherwise damaged and needs to be serviced.Type: GrantFiled: May 12, 2003Date of Patent: February 24, 2004Inventors: Oleg Krioukov, Zoya Krioukova

Patent number: 6634118Abstract: Wood is disposed in a container having at least one flexible wall, and vacuum is applied to the container. The flexible wall presses against a surface of the wood. The container and wood are them immersed in a heated bath (e.g. comprising water, air, or other fluids). The wood is heated by conduction through the flexible wall, and maintained at accurate temperature by the bath. The wood is thereby rapidly dried by heat and vacuum. The present invention is energy efficient, and provides rapid, uniform drying of the wood without checking.Type: GrantFiled: June 28, 2002Date of Patent: October 21, 2003Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Zhangjing Chen, Fred M. Lamb

Patent number: 6625901Abstract: A dryer for drying a substrate includes: a bath containing a fluid; a chamber; and an isopropyl alcohol delivery system supplying isopropyl alcohol vapor to the interface between the substrate and the fluid when the substrate is removed from the fluid of the bath into the chamber. The isopropyl alcohol vapor is supplied perpendicularly to a vertical axis of the substrate. The dryer further includes a chamber environment control system that supplies a gas into the chamber to dry the substrate and controls temperature and humidity in the chamber and a chamber heater attached to the chamber to transfer thermal energy into the chamber. A drying method includes: immersing a substrate into a fluid contained in a bath; removing the substrate from the fluid into a chamber; and supplying isopropyl alcohol vapor into an interface between the substrate and the fluid perpendicularly to a vertical axis of the substrate.Type: GrantFiled: November 20, 2000Date of Patent: September 30, 2003Assignee: Oliver Design, Inc.Inventors: Yassin Mehmandoust, Donald E. Stephens

Patent number: 6620368Abstract: A process which uses sol-gel to process oxide-based monoliths which are virtually free of cracks, without nullifying the desired attributes of the oxide-based monoliths. The method comprises substantially drying a wet porous gel monolith by removing a portion of the liquid from the pores of the gel monolith while the gel monolith remains wet, shrinking in size, and becoming correspondingly more dense, then removing the remaining portion of the liquid from the pores of the gel monolith such that the outer region of the gel monolith is not dried before the inner region of the gel monolith is dried. The gel monolith is substantially dried under conditions in which the liquid evaporation rate is no greater than the pore liquid diffusion rate.Type: GrantFiled: July 13, 2000Date of Patent: September 16, 2003Assignee: Simax Technologies, Inc.Inventors: Shi-Ho Wang, Chih-Hsing Cheng, Sharon Doh

Patent number: 6519871Abstract: A method and apparatus for operating an automatic cycle of a clothes dryer wherein after initiation of an automatic cycle, a CPU displays the expected time remaining during the current cycle. At various times during the cycle, the expected time remaining is updated by comparing the time required to reach certain moisture levels of the articles contained therein to reference times. The comparison also results in the expected times being updated for future uses of the clothes dryer. Finally, the invention includes a system for updating the amount of time required to reach a desired final temperature during a cooldown sequence.Type: GrantFiled: May 25, 2001Date of Patent: February 18, 2003Assignee: Maytag CorporationInventors: Douglas W. Gardner, Michael D. Lafrenz, Kim L. Wright

Patent number: 6381873Abstract: An method for the formation of coating films on substrates which consists of a main high-temperature and high pressure drying chamber with two additional chambers located in front and behind the working chamber, respectively. The front drying chamber, which is installed between the loading station and the working chamber, is intended for drying the coating films at room temperature, while the rear drying chamber is intended for cooling after drying at high temperature and high pressure in the main working chamber. The front and rear chambers are provided with means for adjusting the respective drying and cooling processes by means of respective heating and cooling systems. This allows initial drying in a wider temperature range and final cooling under most optimum conditions.Type: GrantFiled: August 4, 2000Date of Patent: May 7, 2002Inventors: Vladimir Peremychtchev, Joseph Kristul, Igor Rakhvalsky

Patent number: 6357142Abstract: A system for high-pressure drying of semiconductor wafers includes the insertion of a wafer into an open vessel, the immersion of the wafer in a liquid, pressure-sealing of the vessel, pressurization of the vessel with an inert gas, and then the controlled draining of the liquid using a moveable drain that extracts water from a depth maintained just below the gas-liquid interface. Thereafter, the pressure may be reduced in the vessel and the dry and clean wafer may be removed. The high pressure suppresses the boiling point of liquids, thus allowing higher temperatures to be used to optimize reactivity. Megasonic waves are used with pressurized fluid to enhance cleaning performance. Supercritical substances are provided in a sealed vessel containing a wafer to promote cleaning and other treatment.Type: GrantFiled: August 7, 2001Date of Patent: March 19, 2002Assignee: Semitool, Inc.Inventors: Eric J.
