Abstract: A modified atmosphere package for storing oxygen sensitive goods containing a a gas impermeable tray including flanges around the perimeter of the tray and a bottom inside surface, and a a gas impermeable film with a bottom inside surface. The film is fitted with a one-way valve and is positioned over and adjacent to the flanges of said tray, and the film is sealed to such flanges. A support extends from the bottom inside surface of the tray to the bottom inside surface of the gas impermeable film, the support being adapted to prevent the film from collapsing when the atmospheric pressure above the film exceeds the atmospheric pressure below the film.

Abstract: The present invention is an apparatus for use as a grate clip on a traveling stoker grate assembly in a furnace or incinerator. The grate clip apparatus includes a sloping profile along a significant portion of its underside so as to prevent the build-up of ash, fuel and metallic deposits on the grate clip as it traverses a return loop.
