    摘要： Typically, a bottom of a cup-shaped electrode opposes to that of a similar electrode through a predetermined gap and in a mixture of helium and hydrogen. A step-up transformer connected across an AC source through a resistor applies a voltage in excess of a discharge breakdown voltage for the gap across the electrodes to cause a pilot glow discharge between them before the source voltage reaches a glow hold minimum voltage for the electrodes. A rectified voltage resulting from a transformer connected across the resistor turns a bidirectional triode thyristor on to apply the source voltage across the electrodes through the conducting thyristor. This smoothly transits the pilot glow discharge to a glow discharge between the electrodes. The latter discharge heats a liquid forcedly flowing along inner surfaces of the electrodes. Also an auxiliary electrode can be operatively coupled to the electrodes to cause similarly a pilot glow discharge between it and either one of the electrodes. For a DC source a tubular anode surrounds a middle portion of a tubular cathode though which a liquid flows.

    摘要： In a glow-discharge workpiece-treating system's control system, the existence of a direct short-circuit between workpiece and glow-discharge treatment chamber is ascertained. This is done by comparing a voltage-indicating signal and a current-indicating signal against respective threshold levels, and generating a short-circuit signal when the voltage-indicating signal falls below its threshold level and the current-indicating signal exceeds its threshold level. Preferably, the threshold level for the voltage-indicating signal, although lower than the arc-discharge voltage of the system, is higher than the glow-discharge voltage of the system. When used in combination with conventional arc-discharge-responsive switching action, operative for briefly interrupting and then resuming operation in response to each detected arc discharge during normal operation, this can serve to differentiate between arc discharge, which although undesirable is a part of normal operation, and, on the other hand, actual galvanic short circuiting, for which brief interruption of operation constitutes no remedy at all. In a preferred embodiment, the short-circuit detection involves automatic detection of whether the potential difference between the workpiece and the treatment chamber does or does not exceed a threshold level within a predetermined time interval, corresponding to one or several normal-operation brief interruptions of operation.

    摘要： A charge-load support for use in a glow discharge furnace comprises first and second coaxial tubular members joined at one end and capped at the other end to provide a re-entrant entry to the space between the members, the outer member serving to protect the inner member against conductive deposit build-up thereon and the members together defining a relatively long convoluted path from the capping member to the other end thereby serving to reduce the risk of tracking in use of the support.
