20090001004Vibration isolation for filtration equipment - A filter is described that is combined with a device to address vibrations. Such vibrations can adversely impact filter performance. An engine system including this combination is also described.01-01-2009
20090001005Filter system with vibration dampening - A filter is described that is combined with a device to address vibrations. Such vibrations can adversely impact filter performance. An engine system including this combination is also described.01-01-2009
20090020465STANDPIPE WITH FLOW RESTRICTION VALVE, AND FILTER CARTRIDGE - A “no filter, no run” filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.01-22-2009
20090249754Replaceable filter cartridge with removal feature - A replaceable filter cartridge including filter media defining a substantially columnar flow path sandwiched between first and second endcaps. The first endcap includes an opening fluidly connected to the substantially columnar flow path, leading to an interior cavity of the filter media defining a flow path. A sealing flange is aligned with the opening and extends axially away from the filter media. A handle is coupled to the sealing flange or a centerpost such that at least a portion of the handle extends into the flow path.10-08-2009
20100101993FILTER 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
20110073538STANDPIPE WITH FLOW RESTRICTION VALVE, AND FILTER CARTRIDGE - A “no filter, no run” filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.03-31-2011

20100108591Filter with Installation Integrity and Magnetic Flow-Control - A filter with installation integrity permits fluid flow only in a first installation condition and not in a second undesired or mis-installation condition, including improper alignment or mounting of a filter element in a housing, an incorrect replacement filter element, absence of a filter element, and an incorrect housing cover. A magnetically actuated valve has a piston controlling fluid flow according to installation condition.05-06-2010

20100108513CAPILLARY ELECTROPHORESIS USING CLEAR COATED CAPILLARY TUBES - A capillary tube having a hard, optically clear external coating or cladding. In one embodiment, the external clear coating comprises hard-fluoropolymer. The hard-fluoropolymer coating bonds to the fused silica glass, providing higher strength and superior static fatigue performance resulting in vastly improved bending flexibility. The thin hard-fluoropolymer coating of capillaries provides higher initial tensile strength, longer lifetime (resistance to stress corrosion or static fatigue) and superior ability to transmit excitation light and emitted light directly through the coating for fluorescence based detection.05-06-2010
20100170799MULTI-CAPILLARY ELECTROPHORESIS CARTRIDGE INTERFACE MECHANISM - The present invention provides for an interface mechanism in a bio-separation instrument that makes interface connections to a multi-channel cartridge. The interface mechanism precisely positions the cartridge in relation to the support elements in the instrument (e.g., high-voltage, gas pressure, incident radiation and detector), and makes automated, reliable and secured alignments and connections between various components in the cartridge and the support elements in the supporting instrument. The interface mechanism comprises pneumatically or electromechanically driven actuators for engaging support elements in the instrument to components on the cartridge. After the cartridge has been securely received by the interface mechanism, the connection sequence is initiated. The interface provides separate high voltage and optical connections for each separation channel in the cartridge, thus providing channel-to-channel isolation from cross talk both electrically and optically.07-08-2010
20100252437OPTICAL DETECTION ALIGNMENT COUPLING APPARATUS - An apparatus for aligning a capillary column with one or more excitation fibers and with one or more optical lens elements for Capillary Electrophoresis. The apparatus includes two identical blocks having a plurality of grooves for positioning and aligning the capillary column with the one or more excitation fibers, and a plurality of lens seats for optically coupling the lens element with the capillary column. Each block includes a male and female part for mating the two identical blocks together.10-07-2010
20110155572INTEGRATED BIO-ANALYSIS AND SAMPLE PREPARATION SYSTEM - An integrated bio-analysis system incorporates built-in sample preparation capabilities. In one aspect of the present invention, a bio-analysis instrument is provided with a built-in sample preparation device based on PCR (or thermal cycling block/module). In one embodiment of the present invention, a peltier unit in the sample preparation device provides thermal cycling of samples supported in a multi-well tray. In another aspect of the present invention, a CE instrument is provided with a built-in sample preparation capability, which may comprise a sample preparation (bio-molecular reaction) device based on thermal cycler type. In another aspect of the present invention, a PCR device is provided with a built-in analysis device, such as a CE device, for verifying the results of the PCR (bio-molecular reaction) process.06-30-2011

20110253540BIO-ANALYSIS USING BALL-ENDED INCIDENT AND OUTPUT OPTICAL FIBERS - A detection optics configuration for bio-analysis, in which the direction of incident radiation, the axis of the separation channel, and the direction of collection of the output radiation are coplanar at the detection zone. The detection configuration incorporates ball-end optical fibers to direct incident radiation at and collection of output radiation from the detection zone. The detection optics configuration may be implemented in an improved bio-separation instrument, in particular a capillary electrophoresis instrument.10-20-2011
