Abstract: An inlet nozzle assembly includes: a delivery nozzle configured to deliver an effluent stream into an abatement chamber; and a mount configured to couple with an enclosure defining the abatement chamber, the mount being further configured to receive the delivery nozzle, wherein the delivery nozzle is configured to extend from the mount distal from the abatement chamber. In this way, the height of the mount and the location of the abatement chamber can remain fixed for different length delivery nozzles and different amounts of the delivery nozzle extend from the mount, dependent on the length of that nozzle.

Abstract: A valve includes a housing with at least one inlet and at least one outlet; a valve member located within the housing and being moveable between different positions for controlling, in use, the flow of a fluid from an inlet to an outlet of the valve; wherein the valve further includes at least two spaced-apart valve seats in which the valve member is seated so as to form a cavity bounded by the valve seats, an exterior surface of the valve member and an interior surface of the housing; a first conduit extending between the exterior of the housing and the cavity; and a second conduit extending between the cavity and a bore of the valve member, through which conduits, in use, a purge gas can be introduced into the cavity and bore.

Abstract: A pumping line arrangement includes a chamber connecting line which is fluidly connectable to a process chamber that forms part of a semiconductor fabrication tool. The pumping line arrangement also includes a valve module which is fluidly connected to the chamber connecting line. The valve module splits the chamber connecting line into respective first and second pumping lines. The first pumping line is intended to carry a first process flow and the second pumping line is intended to carry a second process flow which is incompatible with the first process flow. At least one of the first pumping line or the second pumping line includes fluidly connected therewithin a pre-abatement module that is configured to remove one or more incompatible constituents from the process flow intended to be carried by the other pumping line.

Abstract: Venturi Scrubbers are used to separate particulate from a large range of fluids. Many provide additional liquid and/or gas to drive the fluid and aid in the removal of particulate. The present invention provides a liquid ring pump through which the fluid to be treated is first passed and then exhausted, with additional work fluid to a Venturi scrubber such that the particulate can be separated from the exhaust fluid.

Abstract: Liquid ring pumps are used to pump a variety of fluid types. The present invention provides a two stage liquid ring pump through which an exhaust gas comprising compounds to be destroyed is passed. The exhaust gas passes through the first stage to a gas abatement device, following which it is passed back to the second stage of the liquid ring pump for removal of the compounds formed in said abatement device. The stages of the liquid ring pump may be adjustable.

Abstract: An inlet assembly for a burner includes a manifold having an inlet aperture and a coaxially aligned outlet aperture, the manifold having a nozzle bore extending along a longitudinal axis between the inlet aperture and the outlet aperture for conveying an effluent gas from an inlet pipe coupleable with the inlet aperture to the outlet aperture for delivery to a combustion chamber of the burner. A nozzle bore scraper is housed within the nozzle bore. An actuator is operable to reciprocate the nozzle bore scraper relative to the nozzle bore, the nozzle bore scraper reciprocating along the longitudinal axis within the nozzle bore between a rest position and an actuated position to reduce effluent gas deposits within the nozzle bore.

Abstract: A vacuum system pipe coupling includes a first coupling member and a second coupling member. The vacuum system pipe coupling has a seal system that is to be positioned to seal between the first and second coupling members and a securing system to releasably secure the first coupling member to the second coupling member. The seal system has an inner seal element and an outer seal element spaced from the inner seal element. The first coupling member is provided with a flow passage configured to conduct a pressurised gas to a space between the inner and outer seal elements to shield the outer seal element from fluid flowing through the pipe coupling in the event of failure of the inner seal element.
