  • Patent number: 7128075
    Abstract: An apparatus for washing parts includes a cleaning chamber including a spray portion and a reservoir portion. The spray portion includes a support for the parts and a spray bar having at least one orifice for distributing a cleaning solution. The reservoir portion stores and collects the cleaning fluid. A thermal energy source adjusts and maintains the operating temperature of the cleaning solution in the reservoir portion. The thermal energy source retains a transfer fluid and includes a heater for adjusting a temperature of the transfer fluid. A conduit extends through the thermal energy source and defines a passageway for the cleaning fluid. A pump draws the cleaning fluid through the passageway and discharges the cleaning solution through the spray bar, such that the operating temperature of the cleaning solution is increased.

  • Patent number: 7028698
    Abstract: Apparatus for pressure processing components is disclosed which includes an improved closure system that minimizes dust-generating parts and allows easy access to the chamber. Ports are provided for introducing and releasing pressurized gases and fluids to and from the processing space. The heating system of the apparatus heats both the cover and the stage inside the pressurized chamber such that cycle time to equilibrate heated, pressurized fluids such as supercritical carbon dioxide inside the chamber are decreased. The apparatus includes a mechanism that raises the stage inside the chamber, pressing it against the fixed cover and sealing the inside of the pressure vessel. In one embodiment a screw-type jack is used to move the component-loaded stage fitted with a deformable o-ring seal a short travel distance to seat against the lid and seal the pressure chamber. In a related embodiment a computer and an electronic stepper motor are used to drive the pressing means in an automated fashion.

  • Patent number: 7018483
    Abstract: Thermal cleaning and separation of metal parts is performed by a stator from an electric motor. Windings embedded in an organic, insulating material are placed and heated to 250°–500° C. under controlled conditions in a heating chamber, evaporating organic material and loosened windings. Flue gas is evaporated organic substances conducted through a closed pipe system to a condensator, where organic gases condense. The pipe system is designed so that condensate is conducted-on in the closed pipe system to a partly liquid filled vessel. Contents of this vessel are air and water that flow concurrently with the condensed flue gas as condensate, increasing content of organic material in the vessel and separating condensate from air. Air may be conducted to the oven for renewed absorption of organic material. All organic material evaporated from the heating chamber is collected in the vessel for later disposal in an environmentally correct and secure way.

  • Patent number: 6899110
    Abstract: The present invention can remove particles such as dust by flowing solvent gas such as CO2 through a line filter and eject it from a nozzle so as to be converted to solid particles or liquid droplets and eject to a workpiece to be cleaned so as to clean particles or organic materials. It is possible to make the solvent to a solid particle or liquid droplet by adjusting a gap between the nozzle and the workpiece to be cleaned; thus, it is possible to select the most preferable state according to the extent of the adhesion of organic material to the workpiece to be cleaned. Also, it is possible to remove particles such dust in the solvent by a line filter; thus, it is not necessary to use highly pure expensive solvent, and it is possible to reduce the running cost of the apparatus.

  • Patent number: 6857437
    Abstract: Initially, process parameters for dense phase fluid cleaning are determined. Thereafter, a cleaning chamber containing a substrate is pressurized with a dense phase fluid, based on these process parameters. The substrate is then cleaned with the dense phase fluid, again based on these process parameters. Exhaust fluid is subsequently expelled from the cleaning chamber, and thereafter analyzed. The process parameters are then adjusted to adjusted process parameters based on the analysis of the exhaust fluid. Thereafter, the cleaning chamber is again pressurized and cleaning repeated. This pressurization and cleaning is based on the adjusted process parameters. Also, this pressurization and cleaning is repeated until the substrate is sufficiently clean.
