  • Patent number: 8088113
    Abstract: 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.

  • Publication number: 20080152815
    Abstract: A self-healing coating, incorporating medium-sized microcapsules filled with a liquid formulation, repairs itself upon physical compromise. In one embodiment, a commercial primer is mixed with these microcapsules and applied. After the coating has cured, any physical compromise of the cured coating results in the microcapsules bursting to release the liquid, in turn filling and sealing the compromised volume of the coating. In applications where a product is used to provide corrosion protection, the liquid contains anti-corrosion material as well as suitable diluents and film-forming compounds. In a preferred embodiment, the microcapsules are provided separately to be mixed with commercial products during preparation for application of the coating. For example, if a paint formulation is known a priori, tailored microcapsules packaged separately from the paint and designed for use with the paint formulation, are wet mixed into the paint during preparation for application.

  • Patent number: 7192993
    Abstract: A liquid self-healing coating, incorporating microcapsules filled with tailored repair formulations, repairs itself upon physical compromise after curing. In one embodiment, a commercially available paint primer is mixed with a pre-specified amount of these microcapsules. After the coating has cured on the substrate to which it is applied, any physical compromise of the cured coating results in the microcapsules bursting to release a liquid that fills and seals the compromised volume of the coating. In applications where paint is used to provide corrosion protection, the liquid contains anti-corrosion material as well as suitable diluents and film-forming compounds. In another embodiment, the microcapsules may be provided separately to enhance commercially available products.

  • Patent number: 6203692
    Abstract: A process for separating chlorine gas from a mixture with other gases is disclosed. In the process, chlorine gas, either as an impure gas or as dissolved gas in hydrochloric acid, is reduced at the cathode of an electrochemical cell to form chloride ions, which are discharged at the anode of the same cell as pure chlorine gas. An apparatus for performing the process is also disclosed.

  • Patent number: 5136474
    Abstract: Disclosed is a high-energy-density all-solid ionomer electrochemical capacitor, completely free of liquid electrolyte. The capacitor includes 1) a three-dimensional metal oxide-particulate-ionomer composite electrode structure, whereby the ionomer coats the individual particles and provides a mechanism for continuous proton transport throughout the composite structure and 2) a unitized repeating cell element that includes this three-dimensional composite electrode structure. The composite electrode structures are bonded to opposite sides of a thin sheet of a solid proton-conducting ionomer membrane and form an integrally bonded membrane and electrode assembly (MEA). The composite electrodes of the MEA are pressed against thin electrically conductive current collectors to form a repeating element in a bipolar cell capacitor arrangement. Energy storage and discharge are achieved by utilizing double-layer and reversible redox processes.
