An electrode assembly comprising concentric tubular electrodes is provided for high temperature processing of materials. The electrode assembly is connected with a power supply that includes switching means for alternatively operating the electrode assembly in a transferred mode of operation, in a non-transferred mode of operation, or according to a controlled sequence of non-transferred and transferred modes of operation. The power supply system includes variable inductors, such as leakage-coupled reactors, for controlling the electrical power supplied to the electrodes for producing a DC arc. The electrode assembly can be incorporated into an arc furnace for processing waste material in the furnace. The electrode assembly is also suitable for use in the practice of in-situ vitrification and remediation of contaminated soil. During in-situ vitrification, the electrode assembly may also be operated in the non-transferred mode, while being withdrawn from holes in the earth, to produce vitrified columns of soil.

An arc furnace that utilizes a combined DC arc system and an AC joule heating system to melt the waste disposed therein and to keep the waste material in a molten condition. The DC arc system utilizes the AC joule heating electrodes as part of the DC current path, thereby eliminating the need for a counter DC electrode. Furthermore, the AC joule heating system provides for peripheral and radial AC current flow to neighboring AC joule heating electrodes, thereby creating a stirring effect in the molten waste. This design greatly simplifies the arc furnace control system while providing a more effective thermal control of the molten waste.

Microwave-induced plasma for continuous, real time trace element monitoring under harsh and variable conditions. The sensor includes a source of high power microwave energy and a shorted waveguide made of a microwave conductive, high temperature capability refractory material communicating with the source of the microwave energy to generate a plasma. The high power waveguide is constructed to be robust in a hot, hostile environment. It includes an aperture for the passage of gases to be analyzed and a spectrometer is connected to receive light from the plasma. Provision is made for real time in situ calibration. The spectrometer disperses the light, which is then analyzed by a computer. The sensor is capable of making continuous, real time quantitative measurements of desired elements, such as the heavy metals lead and mercury. The invention may be incorporated into a high temperature process device and implemented in situ for example, such as with a DC graphite electrode plasma arc furnace.

This loss-of-vacuum detecting means for a vacuum circuit breaker utilizes input information derived from the current transformers of the overcurrent-sensing means typically present in medium voltage switchgear. In this overcurrent-sensing means, the current transformer secondaries for the respective phases of the switchgear are connected in parallel with each other across a shorting conductor; and in series with each secondary is the operating coil of an overcurrent relay. Connected in the shorting conductor is an "a" switch that is closed when the vacuum circuit breaker is closed and is opened when the circuit breaker is opened. Rectifying means is connected across said switch for developing a d. c. voltage when said switch is opened and one or more of said secondary windings is energized. Time-delay relay means is arranged to be energized by said d. c.

The present invention provides a relatively compact self-powered, tunable waste conversion system and apparatus which has the advantage of highly robust operation which provides complete or substantially complete conversion of a wide range of waste streams into useful gas and a stable, nonleachable solid product at a single location with greatly reduced air pollution to meet air quality standards. The system provides the capability for highly efficient conversion of waste into high quality combustible gas and for high efficiency conversion of the gas into electricity by utilizing a high efficiency gas turbine or by an internal combustion engine. The solid product can be suitable for various commercial applications. Alternatively, the solid product stream, which is a safe, stable material, may be disposed of without special considerations as hazardous material. In the preferred embodiment of the invention, the arc plasma furnace and joule heated melter are formed as a fully integrated unit with a common melt pool having circuit arrangements for the simultaneous independently controllable operation of both the arc plasma and the joule heated portions of the unit without interference with one another.

A method and portable apparatus for self-powered, sensitive analysis of solid, liquid or gas samples for the presence of elements is provided. The apparatus includes a compact sensor system which utilizes a microwave power source and a shorted waveguide to induce a plasma. The microwave power source may be a magnetron or the like. The device includes a portable power supply and preferably includes a portable battery charger. The portable power supply includes a compact generator- internal combustion engine unit. The device can be operated by directly using power from the portable power supply or in a more compact embodiment by using power from batteries that are recharged by a separate portable power supply module. Pulsed microwave operation can be used to reduce average power requirements and facilitate the use of very compact units using batteries. The device is capable of being transported to and from remote sites for analysis by an individual without the need for heavy transportation equipment.

A well drilling assembly including a drill bit projecting beyond the bottom of a hollow casing at the bottom of the hole. A fluid motor mounted in the casing has a rotary shaft to rotate the drill bit. The lower end of the rotary shaft is hollow to provide a central flow passage therein, and has an outer pressure diameter less than the inner diameter of said casing to provide an outer pressure passage therealong. Bearings are mounted in the outer passage to support the shaft against radial and axial displacement, and are engulfed in a body of lubricant confined between upper and lower floating seals which limit flow of drilling mud into the lubricant and flow of lubricant from the body into the drilling mud. A labyrinth provides a rotating orifice in the outer passage below the lower seals to maintain a pressure differential between the exterior of said drill bit and the lower seals.
