  • Patent number: 8240013
    Abstract: A casket and burial system for human remains includes a casket fabricated from plastics and polymer composites, such as glass-fiber reinforced plastic. The casket includes a base member, a cover member fitting atop the base, and top and bottom closure panels having one or more ports for use in replacing the ambient atmosphere within the sealed casket with a selected gas or fluid such as nitrogen, or to inject a plastic foam into the free space remaining in the casket. The casket is preferably interred in a vertical attitude as that arrangement allows up to four caskets to fit within a standard grave plot.

  • Patent number: 5800651
    Abstract: A method is provided for pultruding a glass reinforced plastic door panel that is field alterable to fit an out-of-true frame. A mixture of reinforcing fibers and resin is pulled through a set of dies to form a panel having a pair of face sheets that are spaced apart by a hinge side stile at one panel edge and a strike, or lock, side stile at the other panel edge. The hinge side stile is arranged perpendicularly to the face sheets to form a closed panel edge, and the strike side stile is formed as a thick-walled structural channel open to the panel side. The pultruded panel is thereafter cut to lengths equal to the desired height of a door panel.

  • Patent number: 5653075
    Abstract: A glass reinforce plastic door panel of unitary construction that is field alterable to fit an out-of-true frame is provided. The door panel is arranged with a strike, or lock, side stile formed as a thick-walled structural channel open to the panel side. Alteration of the door is accomplished by trimming the channel walls without otherwise affecting the integrity of the panel. After trimming the channel walls, a flexible cap strip is emplaced within the channel to form a finished door edge.
