摘要： 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.

摘要： The present invention is an apparatus and process for cleaning substrates using dense fluids under the influence of centrifugal force and dense fluid phase changes. A perforated centrifuge drum operates within a pressure vessel having drains and fill ports. System controls include a high optical sensor, a low optical sensor, a pressure transducer, and a thermocouple. An external dense fluid cleaning and management system exchanges dense fluid and gas with the pressure vessel via the drain and fill ports. Dense fluid centrifugal separations prevent pooling and supercooling of liquid carbon dioxide avoiding recontamination of the substrate. The present invention can perform solvent-aided separation processes including liquid-liquid, liquid-supercritical-fluid, froth flotation and centrifugal phase-shift separations.

摘要： A process for coating a substrate with a chosen material comprising placing the substrate in a coating chamber and contacting the substrate with a mixture of the selected coating material in a chosen dense phase gas at a selected temperature and a pressure equal to or above the critical pressure of the dense phase gas for a period of time which is sufficient to allow complete penetration of the mixture into all surfaces of the substrate. Then, the phase of the dense phase gas is shifted to produce dissolution of the chosen material from the dense phase gas and to thereby form the coating of the chosen material on the substrate.

摘要： A process for removing two or more contaminants from a substrate in a single process. The substrate to be cleaned is contacted with a dense phase gas at or above the critical pressure thereof. The phase of the dense phase gas is then shifted between the liquid state and the supercritical state by varying the temperature of the dense fluid in a series of steps between temperatures above and below the critical temperature of the dense fluid. After completion of each step in the temperature change, the temperature is maintained for a predetermined period of time in order to allow contact with the substrate and contaminants and removal of the contaminants. At each step in the temperature change, the dense phase gas possesses different cohesive energy density or solubility properties. Thus, this phase shifting of the dense fluid provides removal of a variety of contaminants from the substrate without the necessity of utilizing different solvents. In alternative embodiments, ultraviolet radiation, ultrasonic energy, or reactive dense phase gas or additives may additionally be used.

摘要： An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO2 composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO2 and additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), CO2 particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO2 particles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical CO2 particle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.

摘要： A method of forming and delivering a carbonated machining fluid to be used in a machining process, the machining process including a tool contacting a substrate, comprises supplying a pressure vessel with a non-carbonated machining fluid and non-supercritical carbon dioxide. The machining fluid and carbon dioxide are allowed to admix such that at least a portion of the carbon dioxide dissolves into the machining fluid to form the carbonated machining fluid. The carbonated machining fluid is then delivered under pressure from the vessel to an applicator and applied to the tool or the substrate to impart cooling and lubricating effects.
