| 20090090668 | FUEL FILTER ASSEMBLY WITH FLOW RESTRICTION VALVE - A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control valve is provided on a standpipe to control the flow of fuel into the standpipe. The valve has a component that has a first position at which any flow through the flow passage past the valve is insufficient to permit engine operation, and a second position at which a greater amount of flow through the flow passage is permitted by the valve in an amount sufficient to permit engine operation, and the component rotates about the longitudinal axis when it moves from the first position to the second position and from the second position to the first position. | 04-09-2009 |
| 20090114588 | FUEL FILTER ASSEMBLY WITH FLOW RESTRICTION SLEEVE - A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control sleeve is provided on a standpipe to control the flow of fluid, for example fuel, into the standpipe. The sleeve can be axially moveable between closed and open positions, with one or more members on an installed filter cartridge designed to release the sleeve to permit the movement from the closed position to the open position to allow fluid flow. A spring acts on the sleeve to bias the sleeve back to the closed position upon removal of the filter cartridge. The sleeve can also be designed without axial movement, but nonetheless is configured to be opened and closed to control fluid flow into the standpipe. | 05-07-2009 |
| 20090242816 | Fuel filter housing with snap lock valve asssembly - A valve assembly that is useable with a fuel filter housing to control the flow of fuel through the fuel filter housing. The valve assembly comprises two primary parts that are connected together via a snap connection, and when the valve assembly is installed on the fuel filter housing, means on the fuel filter housing prevent disconnection of the snap connection. One or both of the primary parts of the valve assembly can be provided with a tamper evident feature that will indicate whether someone has tried to remove or disassemble the valve assembly. | 10-01-2009 |
| 20090242820 | FUEL FILTER HOUSING WITH SNAP LOCK VALVE ASSEMBLY - A valve assembly that is useable with a fuel filter housing to control the flow of fuel through the fuel filter housing. The valve assembly comprises two primary parts that are connected together via a snap connection, and when the valve assembly is installed on the fuel filter housing, means on the fuel filter housing prevent disconnection of the snap connection. One or both of the primary parts of the valve assembly can be provided with a tamper evident feature that will indicate whether someone has tried to remove or disassemble the valve assembly. | 10-01-2009 |
| 20100101993 | FILTER CARTRIDGE HAVING A FILTER WITHIN A FILTER, AND AN ENDPLATE SEALING STRUCTURE ON AN OUTER FILTER ELEMENT - A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement. | 04-29-2010 |
| 20100213115 | NO FILTER NO RUN FLUID FILTRATION SYSTEMS - Improvements to “no filter, no run” fluid filtration systems are described. In one example, a filter includes a movable pin cage that has a first pre-installation position adjacent the bottom end plate and is temporarily connected thereto by a snap connection system, and a second position adjacent the upper end plate where it performs a valve interaction function. In another example, a filter includes non-centered valve pins that are rotatable relative to an upper end plate of the filter. | 08-26-2010 |

| 20090294095 | METHOD AND APPARATUS FOR MANAGING AMBIENT CONDITIONS - A heat transfer system with a surface member having a first surface and a second surface, forming a heat transfer surface, and a thermal conduit attached to and spaced across the first surface, the thermal conduit adapted to receive a thermal media to heat or cool the heat transfer surface to heat or cool a body within the heat transfer surface. A method of heating or cooling a body including providing a heat transfer system comprising a surface member having a first surface and a second surface, forming a heat transfer surface, and a thermal conduit attached to and spaced across the first surface, the thermal conduit adapted to receive a thermal media to heat or cool the heat transfer surface, positioning the heat transfer system proximate the body, and supplying heated or cooled thermal media to the heat transfer system to heat or cool the body. | 12-03-2009 |
| 20110073274 | MODULAR CLIMATE CHANGE TARP SYSTEM - A heat transfer system having a flexible surface member having a first side and a second side, forming a heat transfer surface, and two or more thermal conduits, spaced apart and extending across a portion of the heat transfer surface, the two or more thermal conduits adapted to receive a thermal media to form a heat source (heating) or heat sink (cooling) across the heat transfer surface. The flexible surface member may have a plurality of edge regions, the two or more thermal conduits extending between edge regions, such as adjacent edge regions or opposing edge regions. The flexible surface member may have a plurality of corner regions, the two or more thermal conduits extending between corner regions, such as adjacent corner regions or opposing corner regions. | 03-31-2011 |
