  • Patent number: 8075672
    Abstract: Hydroxylamine is formed in a reactor through a partial hydrogenation of nitric oxide gas (NO) with hydrogen gas (H2) in an aqueous medium with nitrogen gas (N2) as an inert gas. The formation of the hydroxylamine forms nitrous oxide gas (N2O). The gases and the water vapor are flowed away from the reactor in a vent gas stream enabling recycling of the gases. The N2O is removed from the vent gas stream to reduce flammability. Once the N2O is removed, the NO, H2, and N2 are recycled and re-used in the reactor to form additional hydroxylamine. The N2O removed from the vent gas stream is of high purity and can be commercially sold or economically discarded.

  • Publication number: 20110298878
    Abstract: The invention relates to a method for printing a substrate (7) in a printing machine, in which ink is transferred from a flexible carrier (3) to the substrate (7) in accordance with a predefined pattern by energy being introduced into the ink through the flexible carrier (3) by a device for the introduction of energy, some of the ink evaporating in the area of action of the energy and, as a result, a drop of ink (67) being thrown onto the substrate (7) to be printed, this step being repeated at least once, ink being transferred at least partly to the substrate (7) at the same positions in order to intensify the pattern produced. The substrate is transported through the printing machine (1) during the printing and, after the transfer of ink in step (a), the device for the introduction of energy is controlled in such a way that, during the repetition in step (b), the ink is transferred at the same position again as in step (a). The invention further relates to a printing machine for implementing the method.
