Patent number: 6174382Abstract: A printing screen cleaning and reclaiming apparatus comprises a cleaning device defining a cleaning and reclaiming path and a plurality of low pressure-high volume water washoff stations, in series, along the path. An ink degradent, an emulsion remover, and a degreaser are each applied successively along the path, and an ink removal station, an emulsion removal station, and a degreaser removal station are positioned successively along the path to provide the low pressure-high volume water washoff. Each station is capable of delivering washoff fluid to the screen of up to 20 feet in height and any length in the range of approximately 40-400 psi, and in the range of approximately 10-250 gallons per minute for efficient and inexpensive cleaning of the screen.Type: GrantFiled: April 6, 1999Date of Patent: January 16, 2001Assignee: Intercontinental Chemical CorporationInventors: Albert B. Cord, Cameron W. Cord, Ted K. Parr, Gregory N. Jensen

Patent number: 5769956Abstract: Method by an oscillator screen cleaning apparatus includes an enclosed housing which forms a cleaning chamber having a plurality of spray nozzles positioned therein to spray a printing screen with cleaning solvent. An oscillating mechanism is mounted within the cleaning chamber to move the screen in an oscillating motion in front of the spray nozzles to provide an efficient and effective cleaning of the printing screen. The spray nozzles are arranged in two opposing grid patterns and the screen is oscillated between the grid patterns to provide complete coverage of the screen with spray cleaning solvent. The sprayed solvent is collected, filtered and resprayed onto the screen, and the high spray rate of the apparatus ensures effective cleaning with the re-used solvent. The entire spray system is enclosed within a housing which is coupled to a vapor recovery system so that solvent and solvent vapors do not escape into the environment.Type: GrantFiled: March 27, 1997Date of Patent: June 23, 1998Assignee: Intercontinental Chemical CorporationInventors: Albert B. Cord, Cameron W. Cord, David N. Gehrich, Gregory N. Jensen, Ted K. Parr

Patent number: 5685326Abstract: An oscillator screen cleaning apparatus includes an enclosed housing which forms a cleaning chamber having a plurality of spray nozzles to spray a printing screen. An oscillating mechanism moves the screen in an oscillating motion in front of the spray nozzles for efficient and effective cleaning. Fixed guide brackets extend into the cleaning chamber from the spray nozzles to guide a screen and maintain the screen perpendicular to the spray patterns from the nozzles. The guide brackets will readily guide screens of different widths and heights without requiring constant adaptation. A reservoir is integrated with the enclosed cleaning chamber and a sloped wall captures spray from the cleaning chamber and directs it to the reservoir for recycling. A vertically oriented pump in the reservoir directs cleaning liquid to the spray nozzles and any failure of the pump is contained in the reservoir to prevent leakage.Type: GrantFiled: October 24, 1995Date of Patent: November 11, 1997Assignee: Intercontinental Chemical CorporationInventors: Albert B.

Patent number: 4664721Abstract: Ink cleaning compositions are disclosed which degrade or solubilize broad classes of printing ink residues on printing screens for quick removal by a pressurized water stream. The compositions are essentially non-aqueous and contain N-methyl-2-pyrrolidone (NMP), an oxygenated solvent, such as butyl cellosolve and cyclohexanone, and a surfactant. Alternatingly, compositions containing NMP and tetrahydrofurfuryl alcohol as the primary components are disclosed. Methods of cleaning and reclaiming printing screens which provide synergistic activities are also disclosed. The compositions meet health and safety standards due to their biodegradability, lack of flammability and high threshold limit values.Type: GrantFiled: December 11, 1985Date of Patent: May 12, 1987Assignee: Intercontinental Chemical CorporationInventor: Gary M.
