Patent number: 10422076Abstract: A powered pneumatic system for capturing a rejected tissue sheet on a parent roll for recycling.The parent roll is supported on a powered parent roll back stand, which turns the parent roll to unwind it. The sheet is drawn into the inlet of a wide pneumatic hood. Suction pressure supplied by a material-handling fan draws the sheet through a duct, where the material-handling fanbreaks it up. The air with entrained, broken paper may be supplied either to a dry system, typically including a separator to separate the paper from the air, or to a wet system for pulping the paper. A trim receiver is one example of a dry system separator. A Venturi scrubber is one example of a wet system. In either case, the paper from the parent roll can be recycled without needing to cut the paper from the roll.Type: GrantFiled: May 14, 2019Date of Patent: September 24, 2019Assignee: Brunn Air Systems, Inc.Inventor: John Kelyman

Patent number: 10364531Abstract: A dust hood for a papermaking system. The hood body has a roof and depending long sidewalls. An inlet extends substantially the entirety of each of the long sidewalls. The hood includes an outlet at one end. The roof is peaked and reaches a peak line. The hood may be positioned at or near floor level and used with air ramps that drive dust toward the inlets.Type: GrantFiled: February 21, 2019Date of Patent: July 30, 2019Assignee: Brunn Air Systems, Inc.Inventors: John Kelyman, Anthony York

Patent number: 10364530Abstract: A below-web dust hood for a papermaking system. The hood body has the general shape of a tapering trapezoidal pyramid, taller at one end than the other. The inlet of the hood body tapers inversely in height—broader where the hood body is shorter, and narrower where the hood body is taller in order to maintain uniform flow across the entire inlet.Type: GrantFiled: February 19, 2019Date of Patent: July 30, 2019Assignee: Brunn Air Systems, Inc.Inventors: John Kelyman, Anthony York

Patent number: 10265741Abstract: A high volume dust collector that is adapted and configured to reduce time associated with routine cleaning of an industrial tissue-machine and factory. The dust collector has a body, having an intake positioned to draw large volumes of air and dust from any area where dust is known to accumulate when engaged. The intake is taller than it is wide and is fitted with a grill to prevent larger maculature from clogging the system. An outlet on each collector connects to a fan or blower and sends collected dust to filtration system. An access hatch is positioned on the body of the collector to allow an operator to manually clear any clogs, should they occur.Type: GrantFiled: March 4, 2018Date of Patent: April 23, 2019Assignee: Brunn Air Systems, Inc.Inventor: John Kelyman

Patent number: 10246827Abstract: An upper reel hood in dust control system for the “dry” side of a through-air drying (TAD) papermaking system. The hood body has the general shape of a tapering trapezoidal pyramid, taller at one end than the other. The inlet of the hood body tapers inversely in height—broader where the hood body is shorter, and narrower where the hood body is taller in order to maintain uniform flow across the entire inlet. The hood body may be over 5 meters wide.Type: GrantFiled: June 18, 2018Date of Patent: April 2, 2019Assignee: Brunn Air Systems, Inc.Inventors: John Kelyman, Anthony York

Patent number: 10190259Abstract: A pneumatic hood for a tissue or papermaking machine is disclosed. The hood has an inlet to admit dust and air. The inlet is defined, in part, by an inlet flap that is hingedly connected to the body of the hood. The inlet flap is coupled to one or more linear actuators, such as pneumatic cylinders, by a linkage such that the linear actuators drive the inlet flap between positions in which the inlet is wider and positions in which the inlet is narrower. Thus, the size of the inlet can be increased to clear large obstructions.Type: GrantFiled: July 6, 2017Date of Patent: January 29, 2019Assignee: Brunn Air Systems, Inc.Inventor: John Kelyman

Patent number: 10023996Abstract: One aspect of the invention relates to a dust control system for the “dry” side of a through-air drying (TAD) papermaking system. A series of dust hoods are placed in specific locations, both above and below the web of paper or tissue that is being manufactured. Each hood spans at least a substantial portion of the width of the belt or web, and each hood is shaped and otherwise adapted for its particular position, both to accommodate the structure of the papermaking machine and to ensure that the airflow through the inlet of the hood is substantially uniform across its entire width. Baffles are provided between certain hoods in order to create dust-control zones around the hoods, and air ramps and other elements may be used to drive dust into the dust control zones and toward the hoods.Type: GrantFiled: September 27, 2017Date of Patent: July 17, 2018Assignee: Brunn Air Systems, IncInventors: John Kelyman, Anthony York

Patent number: 9770684Abstract: An apparatus and method for cleaning a drum filter medium are disclosed. Air with entrained particulate matter, e.g., from a papermaking process, flows through a filter medium positioned along the perforated circumferential surface of a rotating drum. At least some of the particulate matter is caught on or in the filter medium. A set of suction nozzles provided proximate to the surface of the filter medium is provided to draw the particulate matter off of the filter medium. A complementary set of compressed air nozzles simultaneously delivers compressed air to drive particulate matter off of the filter medium and into the suction nozzles. This cleans the filter medium in situ and extends its useful life.Type: GrantFiled: March 20, 2017Date of Patent: September 26, 2017Assignee: Brunn Air Systems, Inc.Inventor: John Kelyman
