Number	Title	Issue Date
7838056	Using carbon dioxide regulators to extend the shelf life of a carbonated beverage A method for replenishing carbon dioxide gas in a carbonated beverage container where a carbon dioxide regulator releases carbon dioxide at a rate approximately equal to the rate of carbon dioxide loss from said container. Also shown is a packaging system for mainta...	11/23/2010
6844418	Waste plastic additive for asphalt The present invention provides an improved polymer additive which may be used to increase the high temperature viscosity of an asphalt, without deleteriously affecting the low-temperature viscosity of the asphalt. The polymer additive may also be used to improve the...	01/18/2005
5929255	Process for coproducing fumaric acid and maleic anhydride The present invention provides a process for recovering fumaric acid formed as a by-product during the production of maleic anhydride so that both fumaric acid and maleic anhydride are obtained. The process of the present invention further eliminates the ...	07/27/1999
5626741	Catalytic cracking with quenching A catalytic cracking process is disclosed in which cracking is performed in a riser reactor, catalytically cracked product is substantially separated from the catalyst in a gross-cut separator downstream of the riser reactor, and the cracked product is qu...	05/06/1997
5279727	Open-bottomed cyclone with solids separation tube and method Open-ended cyclone separators are disclosed which employ catalyst separation tubes to prevent separated solids discharged through an open cyclone end from being entrained in a countercurrently moving flow of process gas entering the separator through the ...	01/18/1994
5262046	In-line cyclone separator and method of solid/gas separation Methods and apparatus are disclosed for separating solids from a mixture of solids and gases. An in-line cyclone separator cyclonically swirls the mixture as it exits a conduit concentrically located within a radially symmetric separation chamber. In some...	11/16/1993
5089235	Catalytic cracking unit with external cyclone and oil quench system Effective quenching is provided in a catalytic cracking unit to increase product yield and decrease thermal cracking.

5087427	Catalytic cracking unit with internal gross cut separator and quench injector Effective quenching is provided in a catalytic cracking unit to increase product yield and decrease thermal cracking. Advantageously, the quench is injected at special locations. In the illustrated embodiment, the quench is injected into the oil product i...	02/11/1992
5059303	Oil stabilization A method for stabilizing oil is provided. An oil fraction having hydrocarbons with an initial boiling point of about 200° F. to about 1050° F. is hydrotreated to reduce the nitrogen content of the oil fraction to be stabilized. Subsequently, condensed a...	10/22/1991
5043058	Quenching downstream of an external vapor catalyst separator Effective quenching is provided in a catalytic cracking process to increase product yield and decrease thermal cracking. To this end, the quench is injected at special locations and a special quench is used. In the illustrated embodiment, the quench is in...	08/27/1991
4786368	Static mixer retorting of oil shale Oil shale is well mixed and efficiently, effectively, and economically retorted in a special gravity flow retorting process and system which utilizes novel arrangements of internal baffles in a static mixer....	11/22/1988
4721560	Static mixer retorting of oil shale Oil shale is well mixed and efficiently, effectively, and economically retorted in a special gravity flow retorting process and system which utilizes novel arrangements of internal baffles in a static mixer....	01/26/1988
4637464	In situ retorting of oil shale with pulsed water purge Product yield and quality is increased during in situ retorting of oil shale by pulsed combustion in which the flow of feed gas to the flame front is intermittently stopped while continuously retorting the oil shale. In the process, a water purge is injec...	01/20/1987
4597852	Static mixer retorting of oil shale Oil shale is well mixed and efficiently, effectively, and economically retorted in a special gravity flow retorting process and system which utilizes novel arrangements of internal baffles in a static mixer....	07/01/1986
4552214	Pulsed in situ retorting in an array of oil shale retorts Greater product yield and quality and continuous upgrading of shale oil with hydrogen-rich, purge mode off gases is attained by pulsing in situ retorts at different phases and intervals. In the process, flow of feed gases to the flame fronts of undergroun...	11/12/1985
4532991	Pulsed retorting with continuous shale oil upgrading One or more in situ oil shale retorts are alternately operated in a combustion mode and a purge mode with a steam or water purge to produce a greater yield of shale oil. Hydrogen-rich off gases emitted during purging are mixed with the shale oil in a reac...	08/06/1985
4457374	Transient response process for detecting in situ retorting conditions A process is provided for determining retorting conditions in an in situ oil shale retort. In the process, the thickness of the hot shale zone is determined by monitoring the off gases in response to changing the feed conditions, such as the temperature o...	07/03/1984
4436344	In situ retorting of oil shale with pulsed combustion Product yield and quality is increased during in situ retorting of oil shale by pulsed combustion in which the flow of feed gas to the flame front is intermittently stopped while continuously retorting the oil shale. A purge gas can be injected into the r...	03/13/1984
