Patent number: 8934702Abstract: A system for determining cumulative tow gap width includes an in-process vision system having at least one camera adapted to record images of a composite material and a data analysis computer communicating with and adapted to receive image data from the in-process vision system. The data analysis computer may be adapted to calculate a cumulative gap width of tow gaps in the composite material. A user interface may communicate with and be adapted to receive data analysis results from the data analysis computer. A method for determining cumulative tow width gap of tow gaps in a composite structure is also disclosed.Type: GrantFiled: January 2, 2008Date of Patent: January 13, 2015Assignee: The Boeing CompanyInventors: Roger W. Engelbart, Reed Hannebaum, Eric Rector, Jeffrey Haywood

Patent number: 6299826Abstract: A gas plenum assembly for a fluidised bed apparatus, including a structure defining one or more side and base walls about a plenum chamber and means defining an inlet for gas to the chamber, arranged so that the gas flows generally upwardly into the chamber from the inlet. The assembly includes distributor means overlying the chamber, having multiple openings through which the gas exits the chamber for forming a fluidised bed above the distributor means. Means are disposed between the inlet and the distributor means for spreading the gas flow among the openings. The gas flow spreader means has a plurality of apertures for the gas flow therethrough, and the gas flow spreader means and the flow apertures are sized and arranged to substantially reduce cross-flow velocity of the gas at the openings.Type: GrantFiled: February 7, 2000Date of Patent: October 9, 2001Assignee: BHP Direct Reduced Iron Pty Ltd.Inventors: Allon Dudley Brent, Ross Jeffrey Haywood, William David Warnica, Grant Caffery
