DEFINITION

Classification: 315/9

(under subclass 1) Systems having a plurality of cathode-ray tube devices connected in the system.

(1) Note. One of the cathode-ray tubes may be in the supply circuit or control circuit of the other cathode-ray tube, or both cathode-ray tubes may constitute load devices in the circuit.

8.61, for plural cathode-ray tube systems utilized in storing or code translation systems.

13.1, for cathode-ray tube systems wherein the cathode-ray tube is provided with a plurality of cathode-ray beams.

324, and indented subclass, and the subclasses specified in the notes to the definitions of those subclasses for systems under the class definition having plural discharge device loads. SEE OR SEARCH CLASS

313, Electric Lamp and Discharge Devices,

2.1, for structures which include a plurality of cathode-ray tubes which are structurally combined so as to form a unitary device (e.g., such as being enclosed within a common envelope) and subclasses 409+ for cathode-ray tubes which are provided with a plurality of cathodes. See subclasses 409+ where the cathode-ray tube has means to form a plurality of cathode-ray beams.
