The removed rubber particles are reused, and can be cleaned and sterilized prior to reinstallation. A method of recycling a synthetic turf field cover includes the steps of removing the existing synthetic turf field cover, aspirating pre-existing rubber and sand particles, sterilizing the rubber particles, reapplying the sterilized, reused rubber particles and applying additional rubber particles and sand to a replaced or reinstalled field turf cover.Type: ApplicationFiled: April 15, 2013Publication date: October 24, 2013Inventors: Patrick D. McAnany, Edwin L. Huggins

Publication number: 20130240118Abstract: A UV-IR combination curing system and method for manufacture and repair of composite parts, such as for use in wind blade manufacture and repair. The system and method utilize UV and IR dual radiation sources to cure glass fiber reinforced laminates containing a photo initiator. The UV and IR dual radiation sources can be configured as discrete stand-alone UV and IR lamps used in a side by side configuration, a plurality of UV lamps with thermal IR radiation, a combined UV/IR lamp, or other forms of light sources providing both UV and IR radiation. To achieve high glass transition and complete curing of thick laminates, the IR radiation source is initially turned on to heat the laminate to close to 40° C.-100° C. before the UV radiation source is turned on. The IR radiation source can be turned off after UV radiation source is activated.Type: ApplicationFiled: February 19, 2013Publication date: September 19, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Xiaomei Fang, Thomas Miebach, David Simon, Jordan Philip Seeger

Patent number: 8524356Abstract: A composite laminate patch for reworking an inconsistent area in a structure has inner and outer control regions possessing differing interlaminar fracture toughnesses for controlling the advance of a disbond in the patch. One or more separation zones in the patch between the control regions aids in diffusing the fracture energy of the disbond as the disband advances from the inner region to the outer region.Type: GrantFiled: February 17, 2010Date of Patent: September 3, 2013Assignee: The Boeing CompanyInventors: Eugene A. Dan-Jumbo, Russell L Keller, Everett A. Westerman
