(under the class definition) Devices having at least one electrode or shield which is movable relative to another electrode or shield or to some other part of the device.
(1) Note. This subclass includes devices where the electrode or shield is designed to be moved during the operation of the device and also includes devices where the electrode or shield is mounted so as to be moved for adjustment and need not be moved during the operation of the device. For example, included in this and the indented subclasses are spark gaps having one of the electrodes
mounted by means of screw threads so that the electrodes can be moved closer or further apart.

96, Gas Separation: Apparatus, 29, 39+, and 94 for electrical precipitators which have movable electrodes.
191, Electricity: Transmission to Vehicles, appropriate subclasses for means for transmitting electricity from a fixed point or contact to an object which is movable.
314, Electric Lamp and Discharge Devices: Consumable Electrodes, appropriate subclasses for arc lamps and similar discharge devices of the consumable electrode type having an electrode which is movable in order to feed it towards another electrode to maintain the proper length discharge space as the electrode is consumed by the discharge.
315, Electric Lamp and Discharge Devices: Systems,
327+, for systems for supplying electrical energy to discharge devices which are designed to be started by placing the electrodes into contact with each other and then separating the electrodes from each other (e.g., which have a movable electrode), and subclass 357 for electric systems for supplying electrical energy to other discharge devices of the gas or vapor type which have a movable electrode.
