20130186617 | CORROSION MANAGEMENT SYSTEMS FOR VERTICALLY ORIENTED STRUCTURES - Corrosion management systems protecting against or managing corrosion of various components in generally vertically oriented structures, that can be located one or more of aboveground and underground. The corrosion management system includes a dispenser system that dispenses at least one corrosion inhibitor to the structure desired to be protected at a plurality of different vertical heights. | 07-25-2013 |
20130071317 | FUEL PERFORMANCE BOOSTER - Hydrogen is produced from methanol and water under supercritical temperature and pressure conditions desirably without any catalyst. The hydrogen can be produced in situ on an internal combustion engine using a heat source such as the exhaust system of the internal combustion engine to achieve the supercritical temperature. | 03-21-2013 |
20130029120 | A LAMINATE FOR PROTECTING METALS FROM CORROSIVE GASES - A corrosive gas resistant laminate comprises an outer polymer layer desirably containing a volatile corrosion inhibitor therein, a corrosion gas resistant barrier layer that can be a hydrophilic polymer, and a tie layer located between said outer and said barrier layers. The various laminates have improved transmission resistance with regard to corrosive gases such as oxygen, hydrogen sulfide, and halogen gases such as chlorine. The laminates can be used to protect metal during storage and transit. | 01-31-2013 |
20120294768 | CORROSION MANAGEMENT SYSTEMS FOR CONTROLLING, ELIMINATING AND/OR MANAGING CORROSION - The present invention generally relates to corrosion management systems designed to deliver corrosion protection and/or the management of corrosion to a top portion of an enclosure (e.g., storage tanks, cisterns, containers, etc.). In one embodiment, the present invention relates to corrosion management systems designed to deliver corrosion protection and/or the management of corrosion to a top portion, or roof portion, of an enclosure where such a system includes one or more dispensers designed to deliver at least one corrosion inhibitor to a system designed to protect a top portion of an enclosure (e.g., storage tanks, cisterns, containers, etc.). | 11-22-2012 |
20120275951 | System for Decreasing Environmental Corrosion Factors and/or for Delivering One or More Corrosion Inhibiting Compounds to an Enclosure - The present invention generally relates to portable systems designed to deliver one or more corrosion inhibiting compounds to an enclosure, and to method for using same. More specifically, the present invention relates to portable, mobile, self-contained and/or discrete systems designed to deliver one or more corrosion inhibiting compounds to an enclosure while simultaneously purging and/or recycling the interior atmosphere of such an enclosure, and to methods for using same. In another embodiment, the present invention relates to portable systems designed to deliver one or more corrosion inhibiting compounds to an enclosure while simultaneously dehumidifying, purging and/or recycling the interior atmosphere of such an enclosure, and to methods for using same. Another aspect of the present invention is that the recycled atmosphere of the enclosure can be passed through an absorbent that removes and/or collects the volatilized metal corrosion inhibitor compound. The collected corrosion inhibitor can later be reused. | 11-01-2012 |
20120141754 | Laminate for protecting metals from corrosive gases - A corrosive gas resistant laminate comprises an outer polymer layer desirably containing a volatile corrosion inhibitor therein, a corrosion gas resistant barrier layer that can be a hydrophilic polymer, and a tie layer located between said outer and said barrier layers. The various laminates have improved transmission resistance with regard to corrosive gases such as oxygen, hydrogen sulfide, and halogen gases such as chlorine. The laminates can be used to protect metal during storage and transit. | 06-07-2012 |
20120141642 | Laminate for preserving food - An all-purpose plastic laminate or wrap as for preserving food that resists penetration of fluids such as water and gases such as oxygen, hydrogen sulfide, sulfur dioxide, and the like. The laminate includes many different embodiments such as at least one hydrophobic outer layer that is free of any volatile corrosion inhibitors, at least one gas resistant barrier layer that can be a hydrophilic polymer, and at least one hydrophobic inner layer that contains a desired additive such as a food safe preservative or antioxidant therein. Optionally at least one tie layer is located between the outer and/or inner layer and said fluid resistant barrier layer. The laminate when applied as a wrap to a food item provides synergistic protection against fluid penetration. | 06-07-2012 |
20120040151 | RUST-RESISTANT TAPE - The present invention generally relates to rust-resistant tape formulations and/or structures. In one embodiment, the present invention relates to a rust-resistant tape that comprises a polymer base material layer, an adhesive layer and a rust-resistant component. In one embodiment, the adhesive layer adhered to one side of the layer of polymer base material. In another embodiment, the rust-resistant component comprises at least one volatile, or vapor-phase, corrosion inhibitor (VCI) that is placed into the matrix of the polymer base material or the adhesive layer. In still another embodiment, the at least one volatile, or vapor-phase, corrosion inhibitor (VCI) component of the present invention is contained within a discrete layer. In one instance, a rust-resistant tape in accordance with the present invention can be directly applied to a metal surface to be protected. | 02-16-2012 |
20120009082 | Systems and methods for preventing and/or reducing corrosion in various types of tanks containers and closed systems - The present invention relates to methods for preventing and/or reducing the occurrence of corrosion in a variety of articles including, but not limited to, tanks (e.g., storage tanks, septic tanks, fuel tanks, etc.); containers (e.g., shipping containers, storage containers, etc.); semi-closed systems (e.g., fuel systems, septic systems, reservoirs, etc.); and/or closed systems (e.g., waste disposal systems, waste disposal drums or containers, etc.). In another embodiment, the methods of the present invention may be utilized to reduce and/or prevent corrosion in a variety of pipelines (e.g., gas/oil pipelines, water pipelines, sewage lines, etc.). More specifically, the present invention relates to methods for preventing and/or reducing the occurrence of corrosion in a variety of articles including, but not limited to, metallic tanks; metallic containers; pipelines; semi-closed systems; and/or closed systems which are constructed partially or totally from metal. (e.g., steel, iron, copper, brass, aluminum, etc.). | 01-12-2012 |
