Abstract: A clothes treating system includes a treating chamber for receiving clothes and a treating fluid therein, and a piston having a piston head. The piston can be adapted for reciprocating linear motion. Reciprocating motion of the piston head within the chamber agitates the clothes. An inner false wall can be contained within the chamber, and can have a corrugated surface providing frictional agitation of the clothes as the clothes are moved against the corrugated surface by the reciprocal motion of the piston head.

Abstract: A method and apparatus for analyzing, maintaining or adjusting the chemical and physical structure of a CO2 Composite Spray in real-time. A light beam is passed through a portion of the CO2 Composite Spray plume, following which the transmitted light is collected using a detector and analyzed using a computer processing device. Light absorption, reflection and/or florescence data are correlated with CO2 particle density and particle size, spray plume length, organic and inorganic spray additives, and water vapor content. The treatment spray geometry is used to optimize and control a CO2 Composite Spray in precision cleaning, machining, and cooling processes.

Abstract: A method and apparatus is disclosed for the production, delivery and control of microscopic quantities of minute solid carbon dioxide (CO2) particles having uniform density and distribution for use in a CO2 Composite Spray process, which employs compression of liquid carbon dioxide to form a supersaturated liquid, which is then condensed via micro-capillaries into minute and highly energetic solid carbon dioxide particles, which are injected into a propellant gas stream.
