DEFINITION

Classification: 313/150

(under subclass 146) Devices having a movable liquid electrode.

(1) Note. Since all devices having liquid electrodes may

have the electrode moved by tilting the device so as to cause the electrode to flow, this subclass includes only those devices which are provided with a liquid electrode which may be moved by means other than the mere tilting of the device. Some of the devices in this subclass have means for changing the level of a liquid electrode and some are provided with means for producing a jet or fountain of liquid from the region of the liquid electrode for starting a discharge, but the subclass is not limited to such types.

163+, for other discharge devices under the class definition which are provided with liquid electrodes.

SEE OR SEARCH CLASS

315, Electric Lamp and Discharge Devices: Systems, 327+, for systems for supplying electrical energy to discharge devices which have a liquid electrode and which are provided with means for moving the liquid electrode into contact with another electrode to start the device into operation, see subclasses 328+ where the device is designed to be started by tilting the discharge device so as to bring the liquid electrode into contact with another electrode.

362, Illumination,

263+, for liquid electrode type lamps (e.g., mercury vapor lamps) in combination with a separable support for the lamp.
