    Abstract: A waste disposal device having a wall structure defining an incineration space, a torch assembly separate from the wall structure, and first structure cooperating between the torch assembly and wall structure for maintaining the torch assembly in an operative position on the wall structure. The torch assembly has a torch for generating heat in the incineration space with the torch assembly in the operative position. The torch assembly further has second structure for circulating a cooling liquid in heat exchange relationship with the torch assembly, independently of the wall structure, to thereby effect cooling of the torch assembly. In one form, the torch assembly is removably maintained in the operative position on the wall structure.

    Abstract: An apparatus having a thermal scission reactor with a graphite-lined plasma arc chamber for the pyrolytic disposal of toxic or hazardous waste. The thermal scission reactor includes a vessel with the plasma arc chamber surrounded by a water jacket. A tubular plasma arc electrode is provided for reciprocating movement within the plasma arc chamber. A conduit communicates with the tubular plasma arc electrode for the introduction of waste material through the tubular plasma arc electrode into the plasma arc chamber. The tubular plasma arc and an opposing electrode produce a plasma electric arc within the plasma arc chamber. An entry duct communicates with the plasma arc chamber for introduction of solid waste into the plasma arc chamber. An exit duct communicates with the plasma arc chamber for escape of gases and ash from the plasma arc chamber. Graphite liners are provided in the plasma arc chamber, the entry duct and the exit duct. The graphite liners may be impregnated with substances for neutralizing the waste material being processed. Injection ports for introduction of neutralizing agents, water, oxygen or hydrogen into the plasma arc chamber may be provided.

    Abstract: An improved method and plasma torch incinerator or reactor in which the incinerator uses a rotating, materials-receiving drum or chamber for receiving the hot plasma of a plasma torch. By properly constructing the inner surface of the rotatable drum and by varying the speed of rotation of the drum, waste materials can be effectively spread out over the inner surface of the drum to form a relatively thin layer of waste materials which has a large surface area which can be more quickly heated to the desired high temperature provided by the plasma torch. Moreover, the spreading out of the waste materials can cause them to be recirculated and mixed by periodically reducing the speed of rotation of the drum. The plasma of the plasma torch is not directed toward a stationary part of the drum. Instead, the plasma torch is directed at a rotatable portion of the drum which provides for a better heat distribution and permits portions of the drum to cool during the intervals when they are not in direct contact with the plasma. Thus, liquid as well as solid waste materials can be fed together into the rotating drum.

    Abstract: A method and system for detoxification of waste materials, comprising incineration of the waste materials followed by additional contaminant reduction steps. The waste material is separated into solid and liquid portions that are fed separately into a combustion chamber wherein they are exposed to a plasma arc torch to affect combustion, producing a gaseous emissions stream and an obsidian residue. The gaseous emissions stream passes through an emissions control unit to eliminate acid gases, metals, and particulates, producing a cleansed exhaust gas and an emissions residue. The emissions residue is passed through an electroplating unit to reclaim metals. The obsidian residue is pulverized and then treated by a chemical process, or passed through the electroplating unit, to reduce the concentration of unbound barium contained therein, producing an inert obsidian residue that is free of toxic levels of all contaminants.

    Abstract: Disclosed is a hydrogen ion microlithography process for use in microelectronic fabrication and semiconductor device processing. The process comprises the steps of providing a single layer of either an amorphous silicon or hydrogenated amorphous silicon material. A pattern is recorded in a selected layer of amorphous silicon or hydrogenated amorphous silicon materials by preferentially implanting hydrogen ions therein so as to permit the selected layer to serve as a mask-resist wafer suitable for subsequent development and device fabrication. The layer is developed to provide a surface pattern therein adaptable for subsequent use in microelectronic fabrication and semiconductor device processing.
