Publication number: 20100263738Abstract: A vapor pressure equalization assembly having an underpressure relief assembly and an overpressure relief assembly in fluidic communication with the vapor space of a liquid storage tank (vessel). The underpressure and overpressure relief assemblies each have movable pistons sealingly engageable with respective sealing members, and biasing members which exert respective biasing forces to maintain the pistons in sealing engagement with the sealing members. A predetermined underpressure or overpressure differential between the vapor space pressure and atmospheric pressure will cause one of the pistons to open fluidic communication of the vapor space to equalize the vapor space pressure with that of the surrounding atmospheric pressure.Type: ApplicationFiled: June 23, 2009Publication date: October 21, 2010Applicant: Taylor Innovations, L.L.C.Inventor: Julian S.

Patent number: 7810516Abstract: An improved bulk fluid distribution for supplying process fluids to semiconductor process tools. The improved system having an alternating pressure vessel engine substantially eliminates pressure fluctuations in the bulk fluid supply line due to head losses from the changing weight of the fluid in the dispensing vessels. The system also enables flexible control of the flow conditions of the fluid in the fluid supply line.Type: GrantFiled: March 3, 2006Date of Patent: October 12, 2010Assignee: Air Liquide Electronics U.S. LPInventor: David Gerken

Patent number: 7641448Abstract: There is described a method and a system for cleaning an ink chamber (1) of a printing unit. The system includes a storage tank (10) which via a high-pressure pump (9) is connected with a hydrophore (2). In the hydrophore a high pressure is built up, and the hydrophore is connected with cleaning nozzles (40) via a valve (5). Thus it becomes possible to inject a shot of cleaning liquid into the chamber by switching the valves (5). The cleaning nozzles are preferably designed as a mushroom-shaped plug (40) with a stem (41) which is mounted in the chamber wall and which has a circular domed top (43) of elastic, resilient material. When injecting cleaning liquid, the elastic plug will spray cleaning liquid out into the chamber, and after shutting off the pressure, there will be a self-closing effect.Type: GrantFiled: March 12, 2005Date of Patent: January 5, 2010Assignee: Tresu Anlæg A/SInventor: Erik Gydesen

Publication number: 20090217451Abstract: An alternative propulsion or motive force for the riders of water features based on generated waves. A wave generator may be used to propel individuals or vessels within a chute for recreation or transportation. In one form, a pool or container having a body of water is configured to support an artificial wave generator which uses compressed gas to discharge water and generate a wave-like motion within a body of water. A source of make-up fluid is configured to mitigate internal low pressure conditions caused by the water discharge to enable effective wave generation with reduced quantities of compressed air. Portions of the waves generated in a pool may be captured in a variety of ways by chutes for stand-alone rides or for portions of chutes in water slides.Type: ApplicationFiled: May 1, 2009Publication date: September 3, 2009Inventor: Garrett T. Johnson

Publication number: 20090217822Abstract: This is a method for regulating pressure inside of a vessel containing a fermenting liquid for the purpose of regulating the amount of dissolved gas in the liquid. This is achieved by replacing the safety relief valve spring on the pressure vessel with a selected spring of known tension to maintain the desired pressure in the vessel. The method will vent excess pressure in the vessel automatically by having the spring compress more under the increased tension from the relief valve, thereby opening the valve and releasing excess gas until the pressure drops to the desired level and closing the valve.Type: ApplicationFiled: February 29, 2008Publication date: September 3, 2009Inventor: Joseph Kent Cyr
