  • Publication number: 20090107116
    Abstract: A device (1) is disclosed for generating gaseous ammonia formed by the hydrolysis of an aqueous solution of urea at elevated temperature and pressure and for feeding the gaseous ammonia into the exhaust gas of an IC engine as it flows through the exhaust system of the engine. The device (1) is placed in the exhaust system and has an inlet (2) for the exhaust gas and an outlet (3) for the exhaust gas so that the exhaust gas will flow through the device (1) during use. The aqueous solution of urea is contained in a reaction vessel located between the inlet (2) and the outlet (3) such that, in use, the vessel and therefore the urea solution are heated by heat exchange with the exhaust gas as it flows from the inlet (2) to the outlet (3).

  • Publication number: 20040098991
    Abstract: A thermoelectric module (1) has a plurality of thermoelectric devices (2) integral with heat conducting surfaces (5, 5′) of fluid chambers (3, 3′). The thermoelectric devices (2) are operable to transfer heat to or from fluids in the chambers (3, 3′). A product, eg a beverage, flowing through one of the chambers (3, 3′) can be heated or cooled to achieve a desired product temperature by selective operation of the thermoelectric devices (2). The module (1) provides an integrated unit that avoids inefficient boundaries between the heat conducting surfaces (5, 5′) and the thermoelectric devices (2).

  • Patent number: 6705489
    Abstract: The present invention comprises a valve providing for the dispensing of two liquids at a desired ratio. The valve includes first and second liquid flow body assemblies releasably securable to a nozzle body assembly. Each liquid flow body assembly is securable to a source of liquid and includes flow sensing means and flow regulating means. A control receives inputs from the flow sensing means and regulates the operation of the flow regulating means to provide for the dispensing of the two liquids from the nozzle body assembly at a predetermined ratio.

  • Publication number: 20040000560
    Abstract: The present invention is a valve that provides for automatic and accurate fluid dispensing of two fluids at a predetermined ratio. The valve is designed to be easily assembled and disassembled by hand without the need for hand tools, and includes a diluent flow body and a concentrate flow body releasably securable to a common nozzle body portion. The diluent and concentrate flow bodies each define a flow channel and each include a first end for connection to sources of diluent and concentrate respectively, and an opposite end for fluid connection with the nozzle body. The diluent body flow channel includes a flow sensor connected to a micro-controller for sensing the flow rate of the diluent. The concentrate body flow channel includes a further flow sensor for sensing the flow rate of the concentrate. Stepper motors are secured to both the diluent and concentrate bodies and each operates a linear rod extending there through and through a flow regulator.
