  • Publication number: 20240160109
    Abstract: Degradation of the reflectivity of one or more reflective optical elements in a system for generating EUV radiation is reduced by the controlled introduction of a gas into a vacuum chamber containing the optical element. The gas may be added to the flow of another gas such as hydrogen or alternated with the introduction of hydrogen radicals.

  • Patent number: 7704420
    Abstract: A spraying device for melt granulation in a fluidized bed including a nozzle (2) with a feed channel for a liquid to be atomized, where the liquid is led through an emulsifying device and into an internal mixing chamber for gas and liquid, before it is fed to the fluidized bed. The nozzle has a separate channel for the atomizing gas fitted concentrically around the central liquid supply channel for the liquid to be atomized or nebulized. The mixing chamber surrounds the outlet zone of the liquid spray from the emulsifying device and the gas, allowing efficient mixing of high speed atomization gas and liquid, and having an external gas cap (1) where fluidization gas is channelled into a spout above the spraying device.

  • Publication number: 20070200007
    Abstract: The invention concerns a spraying device for melt granulation in fluidised bed comprising a nozzle (2) with a feed channel for a liquid to be atomised, where the liquid is led through emulsifying means and into an internal mixing chamber for gas and liquid, before it is fed to the fluidised bed. The nozzle has a separate channel for the atomising gas fitted concentrically around the central liquid supply channel for the liquid to be atomised or nebulised. The mixing chamber surrounds the outlet zone of the liquid spray from the emulsifying means and the gas, allowing efficient mixing of high speed atomisation gas and liquid, and having an external gas cap (1) where fluidisation gas is channelled into a spout above the spraying device.
