摘要： A cartridge (10) for dispensing a reagent contained in a reagent reservoir (32). The reservoir (32) is in fluid communication with a deformable dispense tube (26) that is a least partially compressible, in use, to dispense a volume of reagent from the tube (26). The reservoir (32) defines an enclosed gas space (46) above the reagent, and the cartridge (10) includes a gas vent (40) that, in use, admits gas to the gas space (46) in response to dispense of reagent from the tube (26) that serves to control the reservoir pressure as the reservoir (32) is depleted by subsequent dispensing of reagent. A dispenser employing the cartridge (10) and a method of dispensing a volume of reagent are also disclosed.

摘要： A dispense tap for a frozen beverage machine has a transition section defining a tapered bore with an inlet for frozen beverage from a freeze barrel of the machine and an outlet for frozen beverage controlled by a valve operable by a handle. The handle is rotatable to allow frozen beverage to flow from the transition section through a dispense cavity in the valve for exiting the tap. The outlet has a cross-section greater than the cross-section of the inlet which prevents ice conglomerating and forming a plug in the bore of the transition section.

摘要： Apparatus for generating an ammonia-containing gas is described for use in the selective catalytic reduction of NOx contained in the exhaust gases of an IC engine. The apparatus has a hydrolysis reactor (101) for containing an aqueous solution of urea that is heated, in use, to an elevated temperature by way of heat exchange with the exhaust gases to hydrolyse the urea and liberate ammonia containing gases. A pressure control valve (105) is operable between a substantially closed position for enabling the pressure of the ammonia-containing gas to attain a predetermined elevated pressure within the reactor (101) and an open position when the gas is above the predetermined pressure. A reservoir (106) receives all of the ammonia-containing gas discharged from the reactor (101) when the pressure control valve (101) is in its open position and has an outlet for feeding ammonia-containing gas to the exhaust gases. The reservoir (106) stores ammonia-containing gas during operation of the IC engine and, following the IC engine being switched off, ammonia-containing gas condensate. On cold start-up of the IC engine, the ammonia-containing gas condensate is converted into ammonia-containing gas for feeding to the exhaust gases.

摘要： A fluid flow control valve is provided with means for detecting and quantifying valve seat leakage when the valve is in its closed position. Any fluid leaking past the seat flows through an orifice of known, fixed dimensions present downstream of the seat when the valve is in its closed position. Pressure transducers measure a first pressure immediately upstream of the seat, a second pressure between the seat and the orifice, and a third pressure immediately downstream of the orifice. The second and third pressures are used to calculate flow through the orifice, and the calculated flow is used with the first and second pressures to determine the size of a leak path across the seat.

摘要： 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). A pump (32) is provided for pumping urea solution into the reaction vessel and a controller (33) controls the pump (32) in response to changing NOx output from the IC engine such that, in response to an increase in NOx output, the controller (33) controls the pump (32) to increase the level of urea solution in the reaction vessel, thereby increasing the surface area of urea solution available for heat exchange with the exhaust gas so as to increase the rate of production of gaseous ammonia in the reactor vessel.

摘要： An apparatus for reducing NOx comprising an exhaust conduit (101) of an IC engine (not shown) in which is placed a urea hydrolysis reactor (102) supplied with aqueous urea from urea storage tank (103). Flow of the hot exhaust gas through the exhaust conduit (101) heats the reactor (102) and causes the temperature of the urea therein to rise, promoting its hydrolysis and producing gaseous hydrolysis products. A pressure control valve (106) controls the release of the gaseous hydrolysis products from the reactor to a condenser (107). The condenser (107) is provided with a heat exchanger (108) which has an inlet (109) and an outlet (110) for connection to a coolant supply. When the gaseous hydrolysis gas enters the condenser (107) it is cooled by heat exchange with the engine cooling fluid and the ammonia and steam condense to form a pool of liquid in the bottom of the condenser (107). A dosing valve (112) is provided in the bottom of the condenser (107) to dose the liquid condensate into the exhaust conduit (101) to pass with the exhaust gas through an SCR catalyst on the surface of which the ammonia reacts with the Nox.
