Abstract: An ink jet printing apparatus and method for generating droplets of a printing liquid from a nozzle of an inkjet printhead features a temperature responsive vibrating beam constrained at both ends of the beam within or near a nozzle having an exit opening, the beam being continuously vibrated within the printing liquid in response to electrical pulsing applied to the beam so that the beam vibrates at a predetermined frequency and the beam is at a temperature that is characterized by frequency of vibration that is substantially at a local minimum point whereby minor excursions in temperature of the beam from the local minimum point temperature provides substantially minimal changes in frequency and amplitude of vibration of the beam. A heating element located at or near the exit outlet of the nozzle is selectively heated to provide a heat pulse to a meniscus of the printing liquid at the nozzle exit outlet to selectively control droplet formation and/or droplet direction leaving the printhead.

Abstract: A process for hot or supercritical water oxidative decomposition of wastes, particularly halogenated organic compounds, is described. The process employs a heterogeneous reagent which accelerates the decomposition and is effective to neutralize acidic byproducts. The reagent is maintained in suspension throughout the reaction by operating at conditions of temperature and pressure at which the heterogeneous reagent is largely or fully insoluble in water, and preferably at which liquid water is not present. Production of potentially corrosive brine is also minimized by operating at conditions under which sodium chloride is insoluble.
