Abstract:
1. A portable liquid oxygen (LOX) storage/delivery apparatus, comprising: an insulated LOX container having an interior for containing LOX, the LOX container having a top portion, a bottom portion and a sidewall between the top and bottom portions, the sidewall including a first side portion extending between the top portion and the bottom portion of the container, and a second side portion extending between the top portion and the bottom portion of the container, the second side portion being on an opposite side of said container from said first side portion; and a port system in communication with said interior of said container for charging said container with LOX, and for withdrawing LOX and gaseous oxygen from said container, wherein said gaseous oxygen is withdrawn from said container through a first outlet that opens into the interior of said container at a location adjacent a first juncture between said top portion and said first side portion of said sidewall; wherein LOX is withdrawn from said container through a second outlet that opens into the interior of said container at a location adjacent a second juncture between said bottom portion and said second side portion of said sidewall, the second juncture located generally diagonally from the first juncture relative to the interior of the container; wherein, in a state in which the container is partially filled with gaseous oxygen and partially filled with LOX, the gaseous oxygen can be withdrawn from said container through said first outlet and the LOX can be withdrawn from said container through said second outlet when said container is positioned in a first orientation with said sidewall horizontally oriented, and also when said container is positioned in a second orientation with said sidewall vertically oriented; wherein said first outlet communicates with a first port in said container, said first port being located adjacent said first outlet and said first juncture; wherein said second outlet is in communication with a second port, said second port being located adjacent said first port and adjacent said first juncture, said second outlet being connected to said second port by an LOX conduit extending through the interior of said container; and wherein at least a portion of said first port is substantially concentric with at least a portion of said second port.
