20090235922INFRARED WOK HEATER - An infrared heater for heating a cooking vessel, such as a Chinese wok. The heater includes a block of refractory material, which emits infrared radiation upon heating to an elevated temperature, forming an inverted frustum-shaped cavity or opening. A gas-fired burner having a burner head which produces a laterally directed flame upon ignition of a mixture of a fuel gas and a combustion oxidant supplied to the burner is disposed in the cavity or opening. A planar structure suitable for emitting infrared radiation upon heating to an elevated temperature and forming at least one centralized opening covers the upward oriented base end of the inverted frustum-shaped opening. In accordance with one embodiment, the refractory block is disposed within a cylindrical housing which supports the cooking vessel above the centralized opening during the cooking process.09-24-2009

20090188244Apparatus and Method for Storing and Releasing Sulfur Containing Aromatic Compounds From a Fuel Stream of an Internal Combustion Engine - Disclosed is a fuel filter for removing sulfur containing compounds from an internal combustion fuel stream. In one embodiment, the fuel filter comprises at least one column comprising an adsorbent. In one exemplary embodiment the adsorbent is capable of removing sulfur containing compounds, especially sulfur containing aromatic compounds, from fuels used in internal combustion engines, especially diesel fuels. Also disclosed is an apparatus for extending the life cycle of a post combustion emission control device. In one exemplary embodiment, the apparatus comprises a fuel filter for removing sulfur containing compounds from an internal combustion fuel stream and an emission control device. Finally, a method for removing sulfur containing compounds from an internal combustion fuel stream is disclosed. In one exemplary embodiment, the method comprises passing a fuel through a fuel filter capable of removing sulfur containing compounds, storing the removed sulfur containing compounds, releasing a portion of the stored sulfur containing compounds, and sending the portion through the engine and into an emission control device.07-30-2009

20090027675MOLECULAR DETECTION SYSTEMS AND METHODS - Methods and systems for detecting materials both energetic and non-energetic. An example system passes a sample of fluid through a filter/concentrator (particulate/molecular). Then desorption of the material in the filter/concentrator occurs at a predefined temperature. The desorbed material is analyzed at an optical resonator system to detect presence of a predefined material.01-29-2009
20090139403WATER REMOVAL DOWNSTREAM OF A TURBINE - A rigid or semi-rigid demister pad is positioned between an air turbine and an inertial water removal device such as extractor in an air conditioning system for an aircraft. The demister pad comprises packed fibers or strands whose diameter typically ranges from approximately 10 or fewer microns to approximately 280 microns. The demister is capable of catching very small droplets discharged from the air turbine that coalesce into larger droplets that exit the demister pad and enter an adjacent water removal device downstream from the pad to separate the larger water droplets from the stream of air. This avoids using a water separator containing a coalescer bag that requires frequent maintenance and is sensitive to dirt and freezing. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance.06-04-2009

20080260575TWO-STAGE CATOX APPARATUS AND PROCESS - Apparatus and methods for the production of a secure supply of breathable air are important under conditions where threats from chemical and biological weapons may be present. A catalytic oxidation (CATOX) system may include of at least two primary elements: (1) a catalyst to destroy toxic chemicals by oxidation, and (2) a post treatment filter (PTF, also known as a post treatment adsorbent (PTA)) to remove acidic gases that may be produced by reaction over the catalyst and also remove acidic gases that can not be oxidized. Biological materials may be destroyed by sterilization at the CATOX normal operating temperatures. The catalyst and the post treatment filter may be operated in a two-stage manner, each operating at an independent temperature.10-23-2008
20090232718MULTI-STAGE CATALYTIC AIR PURIFICATION SYSTEM - Apparatus and methods for the production of a secure supply of breathable air are important under conditions where threats from chemical and biological weapons may be present. A method and a multi-stage CATOX system for producing a purified air flow from ambient air which may have nitrogen containing toxicants is provided. The multi-stage CATOX system has a first stage and second stage, at least one of the first or the second stage has a first catalytic heat exchanger with a cold side supporting a first catalyst and a hot side configured to transfer heat therefrom to the first catalyst.09-17-2009
20110026870PHOTONIC CRYSTAL FIBER SENSOR - Systems and methods for sensing a target analyte. An example sensor includes a tunable light source that provides a substantially single optical mode of light, a detector, a processor, and a resonator. The resonator resonates light provided by the light source at a predefined frequency. The resonator includes a photonic crystal fiber having a solid region that guides a substantially single optical mode of light and at least one hollow channel adjacent to the solid region. The hollow channel receives a fluid from an external source. The hollow channel is coated with a film having a material that is reactive with the target analyte in a manner that changes the optical properties of the film. The detector detects light from the resonator. A predetermined change in the detected signal as determined by the processor indicates presence of the target analyte. The material in the film is reversible.02-03-2011
20110105008CATALYTIC AIR PURIFICATION SYSTEM FOR A VEHICLE USING MULTIPLE HEAT SOURCES FROM AN ENGINE - An air purification system for a vehicle may comprise a first heated-ambient-air source comprising an engine with an ambient air compressor; and at least one heated-ambient-air outlet. The system may also comprise a second heated-ambient-air source; a mixing valve; a first heated-ambient-air channel connected between the at least one heated-ambient-air outlet of the engine and the mixing valve; a second heated-ambient-air channel connected between the second heated-ambient-air source and the mixing valve; and a catalytic decontamination unit positioned between the mixing valve and an enclosed passenger cabin of the vehicle for removing contaminants from ambient air and producing decontaminated air to the enclosed passenger cabin.05-05-2011
