|20120237311||METHOD AND APPARATUS FOR THERMAL CONTROL WITHIN A MACHINING PROCESS - Method and apparatus for mixing within a rotary union of a computer numerical control machine a constant pressure gas with a relatively higher-pressure, lower-temperature dense fluid to produce a dense isobaric fluid deliverable through a rotating tool without gelling or solidifying therein. The constant pressure gas may include carbon dioxide, nitrogen, air or mixtures thereof. The dense fluid preferably includes liquid carbon dioxide at or above its triple point. The liquid carbon dioxide and isobaric gas are independently fed to the rotary union. When mixed, a pressurized flowing carbon dioxide machining fluid composition is formed exhibiting a temperature between about 20° F. and 70° F. at pressures between 75 psi and 1,000 psi.||09-20-2012|
|20110233456||METHOD OF FORMING CRYOGENIC FLUID COMPOSITION - A method of forming a machining spray for treating a surface of a substrate during a machining process includes providing a first component containing solid carbon dioxide particles. A second provided component is derived from an inert gas having a temperature range from 305 K to about 477 K prior to being mixed with the solid carbon dioxide particles. The first component and the second component are combined to form the cryogenic fluid composition prior to contacting the substrate. An optional additive may be mixed with the solid carbon dioxide particles or the inert gas. The cryogenic fluid composition exhibits synergistically enhanced physicochemical properties of each component not observed prior to the combination thereof, wherein the fluid imparts enhanced cooling, heating or lubrication effects.||09-29-2011|
|20090178693||EXTRACTION PROCESS UTILZING LIQUIFIED CARBON DIOXIDE - A method for removing contaminants from synthetic resin material includes contacting a particulate synthetic resin material containing at least one contaminant with a solvent other than carbon dioxide. At least a portion of the contaminant is removed from the particulate synthetic resin material and becomes dispersed in the solvent. The solvent, with the contaminant dispersed therein, is then removed from the particulate synthetic resin material. Thereafter, at least a portion of the solvent still contained on the synthetic resin material is removed by contacting the particulate synthetic resin material with liquid carbon dioxide to dissolve the solvent into the carbon dioxide.||07-16-2009|
