  • Double bag vacuum infusion process and system for low cost, advanced composite fabrication
    Patent number: 8851879
    Abstract: Boeing is actively engaged in the production of lightweight composite airframes for both military and commercial applications. The double bag vacuum infusion process of the present invention provides a low cost, method for producing complex composite assemblies without an autoclave. It also enables the production of highly innovative structures. The quality of the composites produced using such an infusion process are comparable to composites made using prepregs, hand layup or fiber placement, and autoclave curing.
    Type: Grant

  • Nail gun magazine for stacked fasteners
    Patent number: 8485410
    Abstract: A magazine for a stack of fasteners in which the mean surface area overlap between adjacent fastener heads is substantial, has a chute, a constantly-urged follower pushing the stack in the chute, a slideway that intersects the chute at a separation station for the lead fastener, and a slide for pushing the lead fastener to an expulsion station and then retracting to get behind the next fastener to dispense from the chute and accede to the separation station, it being the new lead fastener.
