A portable, self-contained device is described for the topical application of oxygen and the removal of wound exudates to promote the healing of skin wounds. The device includes a wound dressing that incorporates at least one electrochemical cell for generating oxygen. The device can regulate the supply of oxygen to the wound at various concentrations, pressures and dosages and is used to produce a high concentration of oxygen at the wound site. By reversing the polarity of the power source a reduced pressure can be created in a reservoir attached to our device. The reduced pressure in the reservoir draws naturally flowing exudates away from the wound. Alternately, two reverse polarity cells are used to alternately supply oxygen and draw away exudates.

An annular flow concentric tube heat exchanger for heating two counter flowing fluid streams has been devised. Although capable of heating gases or liquids, the primary purpose of the invention is to function as an improved recuperator for recovering exhaust heat from a Brayton Cycle gas turbine engine, Ericsson Cycle engine or similar recuperated engine. The basic element of the recuperator is a concentric tube assembly that, in the preferred embodiment, is comprised of four concentric tubes that enclose three concentric annular flow passages. The low pressure exhaust flows through the inner and outer annular passages while the high pressure compressor exit air flows through the annular passage that is between the two low pressure passages. The high and low pressure flows are in opposite directions to achieve the high effectiveness that is only available with a counterflow heat exchanger. Heat is transferred from the exhaust gas to the compressor air though the tube walls on each side of the high pressure passage. Two low pressure passages are provided for each high pressure air passage to compensate for the lower pressure (and therefore lower density) of the exhaust gas. Multiple concentric tube assemblies are used to make a recuperator. The tube assemblies terminate in header assemblies located at each end of the concentric tube assemblies. The headers are made of simple plates and rings that serve the dual function of structurally locating the concentric tube assemblies and directing the flow to the proper passage in the concentric tube assemblies. High and low pressure flow tubes provide flow passages connecting the recuperator to the engine compressor air and exhaust tubing respectively. The annular flow concentric tube recuperator can be easily made from commercial tubing with minimal special tooling and is capable of very high effectiveness with very low pressure drop.

An air-holding protective foam pad construction where open cell foam is enveloped in an air-holding cavity formed by top and bottom air-holding sheets. The foam is not attached to the top and bottom air-holding sheets and the sheets are totally and continuously sealed together around a narrow common perimeter. Upon potentially destructive impact, the open cell foam first absorbs some of the impact force, and secondly the air expelled from the foam bloats the air-holding cavity. The result of the latter is a redistribution of impact forces over a larger surface area, reducing the intensity of force at the site of initial impact. The pad construction thereby has a dual action attenuation of both absorbing and redistributing the intensity of an initial localized impact force.

An improved hand-held two-stage cat-litter scooper tool critically configured to more effectively segregate and lift-away wet cat-litter, without causing migration into, or disturbing clean dry areas. The planar leading-edge of the scooping-blade portion, is formed to either a 90-degree triangular, or transversely-square, plan-view shape; either shape thus able to project closely into the corners of a conventional cat-litter box. The rear portion of either scooping-blade includes an approximate 40-degree transverse-bend, creating an aftward containment-bowl area, effectively holding wet cat-litter when the rearward projecting handle is tilted down (the scooping-blade thus tilting upward) after a horizontal forward scooping motion. The handle is arranged along the medial longitudinal-axis of the tool, angling upward at approximately 45-degrees relative to the plane of the scooping-blade, facilitating the special "tilt-loading action" without dragging of one's hand into the cat-litter. A further aid to performance of the tool being shoved through soiled cat-litter, includes acutely up-turned blade sides; both set slightly back from the actual frontal-sides of the scooping-blade. This particular formation being discovered to function most effectively, providing minimal disturbance to surrounding cat-litter, while very precisely shaving away waste cat-litter. Generic-variations include a preferred 2-piece construction, embodying a stainless-steel blade portion, permanently locking into a retention-groove formed into the aftward injection-molded plastic-body forming the side-walls of the essential containment-bowl; including an integral handle member thereto.
