Patent number: 6719612Abstract: A blast cabinet (10) for ice blasting an article, the cabinet comprising a housing (11) having an interior support (19) for supporting the article. At least one ice blast nozzle (80) is disposed inside the housing and operable to direct a high speed stream of ice particles towards the article. In an embodiment the ice blast nozzle(s) is mounted on a articulated mount (82) wherein the nozzle can be articulated. An energy management system (30, 130) comprising a heating system is provided to facilitate the removal of spent ice particles, and prevent ice accumulation in the enclosure. In an embodiment of the blast cabinet, the energy management system (130) includes a piping assembly (36) a heat exchanger (37) both disposed in the housing.Type: GrantFiled: May 14, 2001Date of Patent: April 13, 2004Assignee: Universal Ice Blast, Inc.Inventors: Sam Visaisouk, Norman W.

Publication number: 20020146967Abstract: The invention provides an apparatus and method for partitioning continuously produced ice particulates and delivering them at a high velocity onto a substrate for treating the surface of the substrate. The apparatus includes a refrigerated curved surface that is brought into contact with water to form a thin, substantially uniform, ice sheet on the surface. This ice sheet is of such thickness as to contain stresses so that the sheet is predisposed to fracture into particulates. A harvesting blade is mounted to intercept a leading edge of the ice sheet and to fragment the ice sheet to produce ice particulates. These ice particulates enter into an inlet where they are fluidized and drawn into a manifold that extends substantially along the length of the harvesting blade. The manifold partitions the particulates into separate delivery tubes where they are ejected from nozzles to the workpiece. The manifold can be created to either evenly or unevenly distribute ice particulates to the delivery tubes.Type: ApplicationFiled: April 5, 2001Publication date: October 10, 2002Applicant: Universal Ice Blast, Inc.Inventors: Sam Visaisouk, Norman W.

Patent number: 6270394Abstract: The invention provides an apparatus and method for continuously delivering ice particulates at high velocity onto a substrate for treating the surface of the substrate. The apparatus includes a refrigerated curved surface that is brought into contact with water to form a thin, substantially uniform, ice sheet on the surface. This ice sheet is of such thickness as to contain stresses so that the sheet is predisposed to fracture into particulates. A doctor-knife is mounted to intercept a leading edge of the ice sheet and to fragment the ice sheet to produce ice particulates. These ice particulates enter into at least one ice-receiving tube that extends substantially along the length of the doctor-knife. Once in the tube, the ice particulates are fluidized by a constant flow of air and are carried into a hose for delivery through an ice-blasting nozzle under pressure.Type: GrantFiled: December 14, 1999Date of Patent: August 7, 2001Assignee: Universal Ice Blast, Inc.Inventors: Sam Visaisouk, Norman W.

Patent number: 6164085Abstract: Containers for transportation of bulk cargo susceptible to spoilage, that have a controlled temperature profile. The refrigerated containers include opposed insulated side walls each of which include internal channels for carrying return air from the floor of the container upward into a plenum. Each plenum is closed at one end, and in fluid communication with a refrigeration unit at the other end to supply return air to the refrigeration unit. Refrigerated air is blown from the refrigeration unit into a central air distribution duct that extends longitudinally along the roof of the container. The central duct is supplied with a multiplicity of spaced apart apertures, and is preferably tapered from a widest point in the vicinity of the refrigeration unit. Thus, substantially equal refrigerated airflow can be obtained throughout the refrigerated container.Type: GrantFiled: March 10, 1999Date of Patent: December 26, 2000Assignee: Cornerstone Technologies, Ltd.Inventors: Richard E. Clarke, Norman W. Fisher
