Patent number: 7337800Abstract: An automatic flushing system for a potable water station includes a conduit having a first end connected to a potable water supply source and a second end having a nozzle coupling. It also includes an air gap assembly having a coupling operable for coupling with the nozzle coupling to releasably connect the conduit to the air gap assembly in a stored position. Further, the system includes a control system operable for automatically flushing potable water through the conduit and the air gap assembly after exceeding a predetermined time in which a predetermined minimum threshold temperature is exceeded and a predetermined time during which the potable water station has remained idle. A method for automatically flushing a potable water station includes the step of providing the potable water station with a conduit having a first end connected to a potable water supply source and having a second end remote therefrom.Type: GrantFiled: November 15, 2004Date of Patent: March 4, 2008Assignee: Semler Industries, Inc.Inventors: Joseph M. Palm, Loren H. Semler

Publication number: 20070277904Abstract: A system (10) and method for substantially automatically aseptically or non-aseptically filling a container with a fluid. The transfer of fluid occurs via a movable nozzle mechanism (20) substantially automatically inserted into a side opening (32) in a connector (12) attached to the container. More specifically, the side opening (32) in the connector (12) is exposed, the nozzle mechanism (20) is moved into the side opening (32), the fluid is transferred into the container via the nozzle mechanism (20) and the connector (12), the nozzle mechanism (20) is removed from the side opening (32) in the connector (12), and the side opening (32) in the connector (12) is closed. The aseptic transfer of fluid includes a substantially automatic sterilization procedure accomplished by both spray and contact components (54,56).Type: ApplicationFiled: March 30, 2007Publication date: December 6, 2007Inventor: Carl Martin

Patent number: 7293675Abstract: Concentrated beverages are supplied from corresponding collapsible bags-in-boxes to a fountain dispenser having multiple dispensing valves and through corresponding beverage supply lines each having an air operated pump. A coupler connects each supply line to a spout on the corresponding beverage bag, and each spout and coupler has a normally closed spring-biased valve. Each beverage supply line is cleaned by a cleaning solution confined within a bag-in-a-box and having a spout connected by another coupler to one end portion of a cleaning solution line having a second end portion with an adapter connected to the coupler on the beverage supply line. A manifold has an inlet connected to the first end portion of the cleaning solution line and multiple outlets with shut-off valves connected to second end portions of corresponding cleaning solution lines so that multiple beverage supply lines to a dispenser may be cleaned simultaneously.Type: GrantFiled: June 1, 2004Date of Patent: November 13, 2007Assignee: VeryFresh Juice Company, Inc.Inventor: Noel G. Luhn

Patent number: 7128084Abstract: The present invention provides a method and apparatus for a self-cleaning valve assembly. The valve is adapted to cycle and thereby clean the valve assembly in response to one or more predefined parameters which are programmed into a programmable controller. The valve is additionally configured to cycle according to one or more of several different methods which have been shown to efficiently clean the valve assembly. In this manner, the valve assembly is automatically cleaned improving the efficiency thereof and eliminating stuck valve warranty returns.Type: GrantFiled: December 21, 2004Date of Patent: October 31, 2006Assignee: General Motors CorporationInventors: Charles F. Long, Phillip F. Mc Cauley, Scott E. Mundy

Patent number: 7013916Abstract: An apparatus for containing and delivering hazardous gases at sub-atmospheric pressure from a pressurized container is provided which includes a valve body in sealed communication with an outlet orifice of the pressurized container. The outlet orifice of the pressurized container is open to an interior chamber of the pressurized container. A fluid discharge path is located in the valve body, between the outlet orifice of the pressurized container and an outlet orifice of the valve body. A pressure regulator having a pressure sensing means capable of responding to sub-atomospheric pressure, is integral to the valve body, in-line in the fluid discharge path with the pressure regulator pre-set to a pressure below atmospheric pressure to allow the gas to be delivered through the regulator from the interior chamber only when the pressure regulator senses a downstream pressure at or below the pre-set pressure.Type: GrantFiled: August 18, 2000Date of Patent: March 21, 2006Assignee: Air Products and Chemicals, Inc.Inventors: Ronald Martin Pearlstein, John Giles Langan, Dao-Hong Zheng, John Irven, Benjamin Lee Hertzler
