  • Patent number: 11309178
    Abstract: The invention provides treatment systems useful to treat microelectronic workpieces with one or more treatment fluids dispensed onto a workpieces from one or more nozzle assemblies. The nozzle assemblies are easily moveable and positionable to change distance and/or angle of nozzle orientation relative to the substrates being treated. The nozzle assemblies are easily and quickly adjustable on demand. Adjustment may be manual or automated. The present invention is based at least in part upon coupling the nozzle directly or indirectly to a flexible bellows. As the bellows is flexed up or down or tilted, etc., the nozzle is moved in a corresponding manner. For example, the nozzle outlet can be moved closer or further away from the surface of the substrate being processed. The angle of the nozzle assembly, and hence the angle of the spray dispensed from the nozzle, with respect to the substrate can also be altered if desired.

  • Patent number: 11287198
    Abstract: An apparatus for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The apparatus is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.

  • Patent number: 11246953
    Abstract: Systems and methods for cleaning and disinfecting contaminated tube lumens are described herein. One system includes an ultraviolet light source and a sterile fluid reservoir fluidly coupled to a liquid light guide. The system is configured to allow simultaneous access and propagation of ultraviolet light and fluid in a tube having a lumen to be cleaned and disinfected. The light guide can be moved inside the tube and simultaneously emit ultraviolet light through its walls and at its distal end into the interior of the contaminated tube. A flush of sterile fluid from an open end of the liquid light guide removes debris and micro-organism detached from the inner surface during light exposure. The sterile fluid can be a high refractive index ionic solution promoting light propagation.
