Patent number: 6182318Abstract: A liquified gas dry-cleaning system including a storage tank containing a liquified gas derived from a liquifiable gas, a pressure vessel for containing a liquid bath derived from the liquifiable gas, and a circulating system for transporting the liquified gas between the storage tank and the pressurized vessel. The pressurized vessel includes a compressor mounted in a wall structure of the vessel for use in evacuating a gaseous form of the liquifiable gas released from the liquid bath during a cleaning cycle. Positioning of the compressor in this manner allows heat generated during each compression stroke of the compressor to be directed to the interior of pressure vessel to minimize the effects of a temperature decrease incident to the gaseous evacuation.Type: GrantFiled: December 17, 1998Date of Patent: February 6, 2001Assignee: Alliance Laundry Systems LLCInventors: James L.

Patent number: 6116255Abstract: Disclosed herein is an apparatus whereby a paint roller can quickly be cleaned, fluffed, and rendered damp-dry with the operator and cleaning area completely shielded from the splatter of solvent and paint. The washing and spin drying actions are produced by a high velocity single jet of water or other solvent delivered through a hand-held spray wand within the confines of a hand-held, tapered cylindrical enclosure.The enclosure is open at the top for insertion of both the paint laden roller and the spray wand, and for visual access into the cleaning process. It's in-rolled upper rim eliminates egress of random splatter. It's open bottom affords rapid exhaust, and being tapered throughout, permits enclosure elements to be nested for efficient quantity packaging. The detachable handle, when affixed to the enclosure and properly adjusted, accommodates nearly any paint roller handle design.Type: GrantFiled: May 4, 1998Date of Patent: September 12, 2000Assignee: The Walter TrustInventor: William R.

Patent number: 6076538Abstract: A method and kit for cleaning jewelry and small paits to 95% and greater clean. A holding basket has a plurality of apertures formed therein, and is adapted to securely retain jewelry and small parts therein. Jewelry is placed in the holding basket and dunked into a container filled with cleaning solution to coat the jewelry with cleaning solution. The holding basket is removed from the container of cleaning solution, and is placed in an automatic dishwasher and run through a wash cycle and dry cycle, thereby exposing the jewelry to impinging water and the action of steam to remove the cleaning solution and grime from the jewelry and small parts. The steam helps prevents formation of water spots. The kit includes a hinged jewelry holding basket with handles and a container filled with cleaning solution. The hinged jewelry holding basket is sized to be dunked into the cleaning solution.Type: GrantFiled: November 25, 1998Date of Patent: June 20, 2000Inventor: Jon Frankson

Patent number: 6044855Abstract: The invention is concerned with a device and a method for cleaning and disinfecting medical instruments, in particular instruments of minimal invasive surgery (MIS). Instead of the rigid connection of cleaning tubings to instrument connections and exits which has been used up to now and which have the disadvantage that certain contaminated regions remain inaccessible for a secure cleaning, there is suggested a docking of injector nozzles in defined chronological intervals, the injector nozzles being fixed in a centric position to the openings of the instrument connections. At the same time various types of injector nozzles are applied for adaptation to various instrument connections and openings. By measuring the rinsing fluid quantity flowing to the instrument connections and the total discharging rinsing fluid quantity, the quality of preparation may be evaluated and documented.Type: GrantFiled: November 12, 1997Date of Patent: April 4, 2000Assignee: Richard Wolf GmbHInventor: Harry Monch
