Abstract: An exhaust gas emissions reactor and method of treating exhaust gas. The reactor has a housing for receiving exhaust gas from an engine. An oxidation catalyst is disposed in the housing for receiving exhaust gas from an inlet, and at least one mixing duct in the housing receives exhaust gas from the oxidation catalyst. An injector introduces reduction agent into the exhaust gas in the mixing duct, and at least one mixer effects mixing of exhaust gas and reduction agent. Disposed in the mixing duct downstream of the injector is an SCR catalyst for receiving exhaust gas/reduction agent mixture therethrough. Treated exhaust gas is conveyed to an outlet of the housing.
Abstract: A device and method for heating exhaust gas from the combustion of fossil fuel upstream of an emissions control device, especially a diesel particulate filter. A conduit receives an exhaust gas flow, and is in fluid communication with the emissions control device for supplying exhaust gas thereto. A flow straightener is disposed in the conduit, and a portion of the exhaust gas flows through the flow straightener. An igniter is disposed in the conduit between the flow straightener and the emissions control device for igniting fuel supplied thereto to produce a flame to heat the exhaust gas flow.

Abstract: A shapeable, glycerine-free cold pack for providing cold therapy, and a method of producing the same, are provided. The pack comprises a plurality of encapsulated units, wherein a mixture of an NaCl based salt dissolved in water is encapsulated in polyacrylamide. An impermeable enclosure contains the encapsulated units or mini-gels to form the pack, which is pliable over a range of temperatures applicable to cold therapy.
