DEFINITION

Classification: 315/129

(under the class definition) Systems provided with signaling means, or indicator means, or alarm means operated by some part of the load device or the electrical circuits therefor to indicate some condition in the load device or the circuits therefor.

(1) Note. The condition indicated may be the operative or inoperative condition of the load device or the circuit therefor, or the time that the load device has been operated, or the degree of heat of some part of the discharge device, or any other desired condition.

(2) Note. This and the indented subclasses do not include systems where a lamp or gas or vapor discharge device is the sole signal or indicator means to show some condition in system except where the casing or mounting for the signal lamp or discharge device which is used as a signal is claimed. Patents excluded are cross-referenced to this or the indented subclasses and are cross-referenced to this or the indented subclasses and are classified either as a plural load device system or in subclasses 88+ where the signal lamp or discharge device is operative only on failure of a first operated lamp or discharge device to operate properly. See the reference to subclasses 88+ under "Search This Class, Subclass", below. Where one of the lamps or discharge devices is claimed broadly as a signaling means, the patent is placed in this or the indented subclasses and cross-referenced to the other appropriate subclasses in this class.

SEE OR SEARCH THIS CLASS, SUBCLASS:

88, and indented subclasses, where the system includes two load devices and the system is arranged so that one of the load devices is energized only after the first load device fails to operate, even though the second operated load device is disclosed and claimed as a signal for the first operated load device, excepting where the casing or mounting for the load device which is used as a signal is claimed when the patent is placed in this subclass (129) or the indented subclasses and cross-referenced to subclass 88, and indented subclasses.

119, and indented subclasses, for systems under the class definition provided with automatically operating means to complete an electrical circuit in shunt about the discharge device or some part thereof, and/or to open the electric

circuit of the discharge device or some part thereof, such means being automatically operated in response to some condition of the discharge device which prevents further operation of the discharge device in the normal manner, especially subclass 120 where the system also includes automatically operating means to open the circuit and/or close a shunt circuit about the load device when the load device fails to operate properly.

116, Signals and Indicators, appropriate subclasses, for nonelectrical signals and indicators of general application.

313, Electric Lamp and Discharge Devices,

10, for the structure of electric lamps and discharge devices which are provided with a temperature indicator and subclasses 323+ for lamps and discharge devices which have combined therewith a signaling means, indicator means or alarm means. In the devices in Class 313 there is no electrical system for supplying current to the lamp or discharge device and there is no electrical system for controlling the signal indicator or alarm. The excluded systems are in this class (315) and not in Class 313.

314, Electric Lamp and Discharge Devices: Consumable Electrodes,

9, for consumable electrode discharge devices, and the systems therefor provided with signaling means, or indicator means, or alarm means.

324, Electricity: Measuring and Testing,

403+, for apparatus or methods for electrically testing electric lamps or space discharge devices.

340, Communications: Electrical,

500+, for electric signaling systems automatically responsive to a condition, particularly subclasses 641+ for a signalling light condition responsive indicating system.
