Abstract: A medicament delivery device includes a housing, a container disposed within the housing and configured to contain medicament, a plunger slidably disposed within the container, a plunger rod configured to push the plunger through the container to dispense the medicament when the container contains medicament, and a gas canister configured to travel with the plunger rod and containing a compressed gas, wherein the gas canister is configured to release the compressed gas to drive the plunger rod to dispense the medicament out of a distal end of the container.

Abstract: A pump for a dialysis machine, the pump having a pump chamber and a deformable membrane actuable to pump a fluid from the pump chamber, the pump chamber being substantially conical such that the membrane is actuated to extend into the conical chamber in order to pump the fluid from the chamber.

Abstract: A method of preparing a dialysate solution for hemodialysis, the method including the steps of providing a mixing pump comprising a pump chamber covered by an actuable membrane, the chamber having a first inlet for admitting water into the chamber, a second inlet for admitting dialysate base solution into the chamber, and an outlet from the chamber, the method including the further steps of providing pump means for dispensing a predetermined volume of dialysate solution base into the chamber at a first pressure, actuating the membrane to draw a volume of water or water mix into the mixing pump chamber at a second pressure, wherein the magnitude of the first pressure is higher than the magnitude of the second pressure so as to ensure the complete dispense of the dialysate solution base into the chamber.

Abstract: A non-coring needle that includes a sharpened and hardened tip having a tapered back region against which a length of tubing is pressed and welded, brazed or soldered. A Luer Lock hub may be attached to the other end of the tubing.

Abstract: A thermo-hydrolysis reactor (1) for producing ammonia-containing gas by heating an aqueous solution of urea is described. The reactor (1) comprises an elongate vessel (2) having a middle tubular section, an enlarged lower section (4) having an inlet (5) for the urea solution, and an enlarged upper section (3) having an outlet (6) therein for the ammonia-containing gas. The reactor (1) is adapted such that, in use, heat transmitted through the walls of the reactor (1) from an external heat source heats the urea solution causing it to hydrolyse producing the ammonia-containing gas.

Abstract: A device 1, capable of being placed in-line in the exhaust conduit of an IC engine upstream of an SCR catalyst, which produces a gaseous hydrolysis product, containing ammonia, which is added to the exhaust gas in a controlled manner to pass therewith through the SCR catalyst to reduce the NOx content of the exhaust gas. The device 1 has an inlet 2 and an outlet 3 for the exhaust gas flowing therethrough and comprises an outer body 4, which forms a pressure barrier, and passing through the outer body 4 is an inner body 5 which comprises a flowpath longitudinally therethrough from the inlet 2 to the outlet 3.

Abstract: 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.

Abstract: An improved underground box and lid for use in irrigation systems and other underground systems is provided. A single box can be inverted, combined and interlocked with a second box to form a single enclosed structure that is twice as high. This can be used for those installations where underground system components are buried in the ground at a greater depth than can be accommodated by a single box.
