Patent number: 6129451Abstract: The invention discloses an apparatus and method for mixing liquid carbon dioxide with an additive or surfactant and then forcibly dispersing the mixture into a cleaning chamber full of liquid carbon dioxide. Valving controls the process of admitting a liquid additive into a two liter reservoir and then admitting liquid carbon dioxide into the two liter reservoir under pressure thus filling the reservoir. The mixture is then admitted to the cleaning chamber under pressure. A nozzle, a plurality of nozzles, or a pipe having apertures therein is used to disperse the mixture inside the cleaning chamber.Type: GrantFiled: January 12, 1998Date of Patent: October 10, 2000Assignee: Snap-Tite Technologies, Inc.Inventors: Larry R. Rosio, Ed D Fulton

Patent number: 6042793Abstract: The invention discloses a plurality of cylindrical slugs linked together by a cable. The slugs are separated by spacers and the cable is crimped at each end thereof to keep the slugs and spacers from coming off the cable. The cable-slugs-spacers assembly is inserted through a guide tube and into an annulus locking the cover of the pressure vessel to the housing of the vessel. A relief mechanism is provided in the cover to ensure that the cable-slugs-spacers assembly is fully inserted in the annulus thus preventing accidental extrication of the cover when the vessel is pressurized. A proximity sensor is positioned in the housing of the vessel and senses the pressure of the first slug inserted into the annulus thus insuring that the cable-slugs-spacers assembly has been fully inserted in the annulus. A coupling is provided on one end of the cable-slugs-spacers assembly to positively lock the assembly in place ensuring that the cover will not be extricated from the pressure vessel under pressure.Type: GrantFiled: December 24, 1997Date of Patent: March 28, 2000Assignee: Snap-Tite Technologies, Inc.Inventors: Larry R. Rosio, Richard K. Reber, Marc Quint

Patent number: 5970554Abstract: An apparatus and method for controlling the use of carbon dioxide in drying cleaning clothes, garments and other fabrics is disclosed and claimed. The components of the invention include a distillation vessel, a compressor, a warm-up vessel, a cleaning chamber, a condenser, and a carbon dioxide storage tank. A programmable logic controller is utilized to control the apparatus. Several modes of use are disclosed. One mode, the reclaim mode, enables the efficient operation of the apparatus. As the name implies the reclaim mode recovers most of the carbon dioxide gas remaining in the cleaning chamber is removed therefrom.Type: GrantFiled: August 28, 1998Date of Patent: October 26, 1999Assignee: Snap-Tite Technologies, Inc.Inventors: Stephen H. Shore, Larry R. Rosio

Patent number: 5526834Abstract: An apparatus for precision cleaning with carbon dioxide includes a pressure vessel having a removable cleaning drum with a sanitized work zone. The sanitized work zone is defined by an impermeable drum body having a removable exit filter to ensure that circulating cleaning fluid does not redeposit contaminants on the parts. The carbon dioxide is maintained in liquid form in the storage vessel, raised above its critical temperature by the preheater, pumped into the pressure vessel to achieve critical pressure, circulated through the work zone for a predetermined period of time, and removed through the let-down valve.Type: GrantFiled: August 17, 1994Date of Patent: June 18, 1996Assignee: Snap-Tite, Inc.Inventors: Richard J. Mielnik, John A. Metalonis, Richard K. Reber, Larry R. Rosio, Stephen H. Shore, Charles W. Smith

Patent number: 5509431Abstract: A method for precision cleaning of a workpiece with a cleaning fluid comprising liquid and/or supercritical fluid carbon dioxide and a primary solvent which is liquid at ambient temperatures and pressures comprises first placing the workpiece in a pressurizable vessel with a removable lid and within an inner tank open at the top; supplying the primary solvent to the inner tank; flushing the primary solvent through the pressure vessel; draining the inner tank to remove the primary solvent; and then supplying liquid and/or supercritical fluid carbon dioxide to the pressure vessel and flushing it through the vessel by withdrawing it from near the bottom of the inner tank.Type: GrantFiled: November 14, 1994Date of Patent: April 23, 1996Assignee: Snap-Tite, Inc.Inventors: Charles W. Smith, Jr., Larry R. Rosio, Stephen H. Shore

Patent number: 5377705Abstract: An improved precision cleaning method includes introducing a solvent to a cleaning vessel, placing a workpiece in the cleaning vessel and contacting the workpiece with the solvent during a residence period. The cleaning vessel is then pressurized to a target pressure by adding carbon dioxide to the vessel, and additional carbon dioxide is pumped into the vessel while maintaining the target pressure to flush contents of the vessel. Cleaning may be enhanced by pressurizing to above the supercritical point of the carbon dioxide, and cleaning is further enhanced by application of sonic energy or mechanical agitation.Type: GrantFiled: September 16, 1993Date of Patent: January 3, 1995Assignee: Autoclave Engineers, Inc.Inventors: Charles W. Smith, Jr., Larry R. Rosio, Stephen H. Shore, James A. Karle

Patent number: 5355901Abstract: An apparatus for precision cleaning with carbon dioxide includes a pressure vessel having a removable cleaning drum with a sanitized work zone, a separator for regenerating spent carbon dioxide, and pressure and temperature monitoring and control devices to maintain the carbon dioxide in a supercritical state while it is circulated in contact with a part to be cleaned. The sanitized work zone is defined by an impermeable drum body having removable entry and exit filters to ensure that circulating cleaning fluid does not redeposit contaminants on the parts. The separator includes distillation means. The pressure vessel and separator form part of an overall system, including a storage vessel for carbon dioxide, a pump, a preheater, a let-down valve in communication with the pressure vessel outlet, a condenser and a bypass.Type: GrantFiled: October 27, 1992Date of Patent: October 18, 1994Assignee: Autoclave Engineers, Ltd.Inventors: Richard J. Mielnik, John A. Metalonis, Richard K. Reber, Larry R. Rosio, Stephen H. Shore, Charles W. Smith

Patent number: 4384703Abstract: A handle for a magnetically actuated valve which bears rotating and fixed indicia for reading the valve position. The rotating indicia is placed upon a jacket carrying drive magnets. The fixed indicia is placed upon a cap covering the exposed end of a nonmagnetic bonnet separating the drive and driven magnet assemblies. External stop means prevent rotation of the jacket relative to the cap and bonnet more than about 90.degree.. Internal stop means prevent the rotation of valve and driven magnets more than about 90.degree..Type: GrantFiled: January 21, 1981Date of Patent: May 24, 1983Assignee: Autoclave Engineers, Inc.Inventors: Robert F. Ruyak, Larry R. Rosio, Theodore R. Silver, Albert E. Straus
