20070261550 - Method of separating nitrogen gas and molecular sieve carbon: where C indicates an oxygen level (ppm) in the nitrogen gas product; Q indicates a volume of nitrogen gas produced per minute per unit effective volume of a single adsorption column; P indicates an adsorption pressure (MPa); and U indicates a ratio of the volume of the feed air to... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, P.C.

20070261551 - Separation of carbon dioxide from other gases: An inventive adsorptive gas separation process is provided capable of producing a purified methane product gas as a light non-adsorbed product gas as opposed to a heavy desorbed exhaust gas component, from a feed gas mixture comprising at least methane, and carbon dioxide. In an embodiment of the invention, the... Agent: Klarquist Sparkman, LLP

20070261552 - Direct gas recirculation heater for optimal desorption of gases in cryogenic gas storage containers: A cryogenic gas storage system for optimal desorption of adsorbed gases, wherein a gas storage material is subjected to enhanced, ample selected recirculation of gas of the same type as the adsorbed gas, at suitable temperature and pressure, so as to supply of heat energy to the material and thereby... Agent: Charles H. Ellerbrock General Motors Corporation

20070256558 - Ejector to reduce permeate backpressure of air separation module: An air separation system includes an ejector for controlling a pressure differential across an air separation module and a valve for controlling air flow through the ejector such that airflow through the ejector is discontinued when not required to maintain the desired pressure differential across the air separation module.... Agent: Carlson, Gaskey & Olds, P.C.

20070256559 - Integrated vacuum absorption steam cycle gas separation: Methods and systems for separating a targeted gas from a gas stream emitted from a power plant. The gas stream is brought into contact with an absorption solution to preferentially absorb the targeted gas to be separated from the gas stream so that an absorbed gas is present within the... Agent: Greer, Burns & Crain

20070251381 - Filter system for electronic equipment enclosure: A filter system including a method for self cleaning the filter system of an electronic equipment enclosure where air flow is monitored either by monitoring fan performance of air flow velocity through the enclosure. The system includes two filters elements, an upstream ASHRAE or HEPA filter element to block particulate... Agent: Harness, Dickey, & Pierce, P.l.c

20070251382 - Separation of light gases from halogens: A process is provided for separating one or more light gases from bromine or chlorine using one or more physical separations and contact with a chemical scrubber to recover additional halogen. In one aspect, the process comprises (a) providing a feed of halogen containing one or more light gases to... Agent: Christie, Parker & Hale, LLP

20070251385 - Dust reduction in delivery of particulate commodities: Apparatus for reducing dust emissions from particulate commodities such as wheat or coal using a curved loading spoon connected to the discharge from a loading spout. The curved loading spoon turns particulate commodities delivered at a rate above a predetermined delivery velocity against a curved outer wall causing dust arising...
