DEFINITION

Classification: 315/265

(under subclass 260) Systems wherein the electrical discharge device is connected to an alternating current supply circuit so that two of the electrodes (such as the anodes) have impressed thereon, alternately, a positive and negative potential, one of these electrodes being positive when the other is negative, and having the electrode (such as the cathode) which cooperates with these electrodes (anodes) connected to a point in the circuit which has a potential intermediate that of the alternating potential impressed on the first mentioned electrodes so that a discharge is established between an anode and a cathode on each half of the alternating current wave.

(1) Note. The discharge device may have two cathodes and an anode with the discharge alternating between the anode and different cathodes.

140, for full wave systems where the supply circuit is a polyphase alternating current system and includes phase multiplying means in the supply circuit.

141, for full wave systems where the supply circuit is a polyphase alternating current system and includes a transformer in the supply circuit.

146, for full wave systems where there are a plurality of discharge control discharge device load devices connected in a polyphase alternating current supply system.

147, for the subject matter where the discharge device is connected to a polyphase alternating current supply system.

195, for full wave systems where there are a plurality of discharge control discharge device load devices in the system, and the system includes means to shift the phase of the control current and/or potential with respect to the current in the cathode-anode circuit.

253, for miscellaneous full wave systems under subclass 246 where there are a plurality of asymmetrical discharge device load devices in the system.
