  • Patent number: 11149605
    Abstract: An exhaust pipe for the exhaust tract of a combustion machine, which has an inlet opening for an air connection, is characterized by an inner pipe section which is surrounded by an outer pipe section in order to form an annular channel that is closed at one end and at the other end is open toward the inner volume of the exhaust pipe, wherein the inlet opening for the air connection opens into the outer pipe section. By means of such an exhaust pipe, advantageous mixing of air supplied via the air connection into the exhaust gas flowing within the exhaust pipe can be achieved with a simple design, which can be attributed in particular to the complete introduction of the air in combination with the flow direction that is present along the longitudinal axis of the annular channel and the exhaust pipe.

  • Patent number: 10996112
    Abstract: Various embodiments of the invention provide systems and methods for accurately determining temperatures in harsh environments such as, for example, in a steam autoclave chamber during a sterilization cycle. In certain embodiments, temperature data accuracy is increased by utilizing an IC-based temperature logging device that monitors and compensates for inherent thermal delays that would otherwise cause a discrepancy between temperature as measured by a temperature sensor and the actual ambient gas temperature. By properly correcting for the thermal delay, the data accuracy of the measured gas temperature is thus greatly enhanced.

  • Patent number: 9476108
    Abstract: The invention provides methods, compositions, and apparatuses for preventing the formation of scale in heap leach process solution distribution systems comprised of piping, spray nozzles, or emitter tubes. Solution distribution system components often become fouled by scale because of local hot spots more prone to form scale than other locations along the systems length. Positioning sensors that detect periods of high temperature stress and adjusting scale control reagent dosage to send the right amount to inhibit hot spot deposition allows for the control of scale without using wasteful excessive amounts of scale control reagents. This can vastly improve scale control performance under high temperature stress conditions while minimizing scale control reagent waste under less severe stress conditions to reduce the total operating cost of running heap leach mining operations which depend upon well-functioning solution distribution systems.

    Abstract: A modular chemical production system includes multiple modules for performing a chemical reaction, particularly of radiochemical compounds, from a remote location. One embodiment comprises a reaction vessel including a moveable heat source with the position thereof relative to the reaction vessel being controllable from a remote position. Alternatively the heat source may be fixed in location and the reaction vial is moveable into and out of the heat source. The reaction vessel has one or more sealing plugs, the positioning of which in relationship to the reaction vessel is controllable from a remote position. Also the one or more reaction vessel sealing plugs can include one or more conduits there through for delivery of reactants, gases at atmospheric or an elevated pressure, inert gases, drawing a vacuum and removal of reaction end products to and from the reaction vial, the reaction vial with sealing plug in position being operable at elevated pressures.

  • Publication number: 20140325968
    Abstract: An exhaust gas purification device has: a catalyst to purify exhaust gas by reduction of nitrogen oxide included in the exhaust gas discharged from a combustion chamber of the engine, which catalyst has a purification efficiency of the nitrogen oxide varying depending on a temperature of the catalyst; a supply means capable of supplying a reduction agent for the reduction of the nitrogen oxide to the exhaust gas guided to the catalyst; and a control means having a configuration capable of controlling the temperature of the catalyst depending on an operating condition of the engine. The device has a configuration to prohibit controlling the temperature of the catalyst when a condition of being incapable of supplying the reduction agent in an amount corresponding to the temperature of the catalyst is satisfied, even if the temperature of the catalyst needs to be controlled.
