Abstract

A filtering unit for filtering particulates from high temperature gases uses a spiral ceramic spring to bias a ceramic, tubular filter element into sealing contact with a flange about an aperture of a metallic tube sheet. The ceramic spiral spring may contact the upper edge of the filter element and be restrained by a stop member spaced from one end of the tube sheet, or the spring may contact the bottom of the filter element and be restrained by a support member spaced from the opposite end of the tube sheet. The stop member and support member are adjustably secured to the tube sheet. A filtering system uses the ceramic spiral spring to bias a plurality of ceramic, tubular filter elements in a respective plurality of apertures in a tube sheet which divides a vessel into upper and lower enclosed sections.

High exhaust temperature, zoned, electrically-heated particulate matter filter

Patent Gonze, Eugene V.; Paratore, Jr., Michael J.; Bhatia, Garima

A system includes a particulate matter (PM) filter, an electric heater, and a control circuit. The electric heater includes multiple zones, which each correspond to longitudinal zones along a length of the PM filter. A first zone includes multiple discontinuous sub-zones. The control circuit determines whether regeneration is needed based on an estimated level of loading of the PM filter and an exhaust flow rate. In response to a determination that regeneration is needed, the control circuit: controls an operating parameter of an engine to increase an exhaust temperature to a first temperature during a first period; after the firstmore »« less

Stable organic photosensitive devices with exciton-blocking charge carrier filters utilizing high glass transition temperature materials

Patent Forrest, Stephen R.; Burlingame, Quinn; Xiao, Xin; ...

Disclosed herein are stable organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material having a sufficiently high glass transition temperature, e.g., higher than the temperature or temperature range at which the device typically operates, higher than a highest operating temperature of the device, higher than a threshold temperature value, etc. and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

High performance internal reforming unit for high temperature fuel cells

Patent Ma, Zhiwen [Sandy Hook, CT]; Venkataraman, Ramakrishnan [New Milford, CT]; Novacco, Lawrence J [Brookfield, CT]

A fuel reformer having an enclosure with first and second opposing surfaces, a sidewall connecting the first and second opposing surfaces and an inlet port and an outlet port in the sidewall. A plate assembly supporting a catalyst and baffles are also disposed in the enclosure. A main baffle extends into the enclosure from a point of the sidewall between the inlet and outlet ports. The main baffle cooperates with the enclosure and the plate assembly to establish a path for the flow of fuel gas through the reformer from the inlet port to the outlet port. At least amore »« less

Method and apparatus for enhanced evanescent fluorescence and color filtering using a high refractive index thin film coating

Patent Kao, Hung Pin [2124 Promontory Cir., San Ramon, CA 94583]; Schoeniger, Joseph [126 Echo Ave., Oakland, CA 94611]; Yang, Nancy [72 Bacon Ct., Lafayette, CA 94549]

A technique for increasing the excitation and collection of evanescent fluorescence radiation emanating from a fiber optic sensor having a high refractive index (n.sub.r), dielectric thin film coating has been disclosed and described. The invention comprises a clad optical fiber core whose cladding is removed on a distal end, the distal end coated with a thin, non-porous, titanium dioxide sol-gel coating. It has been shown that such a fiber will exhibit increased fluorescence coupling due in part by 1) increasing the intensity of the evanescent field at the fiber core surface by a constructive interference effect on the propagating light,more »« less
