20080283382 - Device and method for measuring elemental sulfur in gas in gas lines: A device and method for measuring the level of elemental sulfur present in a gas in a gas line. The device may include: an access fitting detachably connectable with the gas line, the access fitting having a first end and a second end; a probe detachably connectable to at least... Agent: Bracewell & Giuliani LLP

20080283383 - Method for the distillative purification of slow-evaporating fluids: The present invention relates to a method for removing volatile compounds from sparingly volatile fluids by means of rectification using an auxiliary and also to separation methods and chemical reactions in which sparingly volatile fluids are used, the purification of which is effected by means of rectification and using an... Agent: Norris, Mclaughlin & Marcus, P.A.

20080283384 - Process for producing trioxane and at least one comonomer: The invention relates to a process for preparing trioxane and at least one comonomer for preparing (co)polymers based on trioxane, in which, in a first step, formaldehyde the at least one comonomer reactant are reacted in aqueous solution to give trioxane and comonomer, to obtain a reaction mixture A1 comprising... Agent: Connolly Bove Lodge & Hutz, LLP

20080277262 - System and method for wastewater reduction and freshwater generation: A process whereby freshwater is generated and wastewater is eliminated through the employ of waste combustion gas; wherein combustion gas is cooled below dewpoint, via the effects of a wastewater fed evaporative cooler, resulting in the combined benefits of freshwater generation from the combustion gas and evaporative reduction of the... Agent: Dubois, Bryant, Campbell & Schwartz, LLP

20080277263 - Method and apparatus for treatment of impotable water: Apparatus and method are provided for treatment of impotable water and for optionally simultaneously creating surplus electricity. Briefly, water is marshaled through a series of chambers by variances in pressure which are created as the water changes state from liquid to gas and from gas to liquid. The source or...
