  • Patent number: 7730887
    Abstract: A portable gas fractionalization apparatus that provides oxygen rich air to patients is provided. The apparatus is compact, lightweight, and low-noise. The components are assembled in a housing that is divided into two compartments. One compartment is maintained at a lower temperature than the other compartment. The lower temperature compartment is configured for mounting components that can be damaged by heat. The higher temperature compartment is configured for mounting heat generating components. An air stream is directed to flow from an ambient air inlet to an air outlet constantly so that there is always a fresh source of cooling air. The apparatus utilizes a PSA unit to produce an oxygen enriched product. The PSA unit incorporates a novel single ended column design in which all flow paths and valves can be co-located on a single integrated manifold. The apparatus also can be used in conjunction with a satellite conserver and a mobility cart.

  • Patent number: 6374645
    Abstract: There is disclosed herein a relatively simple locking device for sporting items such as skateboards, snowboards, snow skis, and the like. In one form of the locking device, the same includes a member which can be affixed to a wheel truck of a skateboard, binding of a snowboard, or binding of a snow ski, and includes a releasable cable which can be wrapped around a fixed or stationary object so as to secure the sporting item. In one embodiment, the cable can be extended and retracted from the body of the locking device so as to provide a suitable length of the cable for the securing function. In another embodiment, the cable is normally retained in a flanged section of the locking device, but can be released therefrom for attachment to the fixed or stationary object.
