DEFINITION

Classification: 264/272.16

Transducer, or electric lamp or space discharge device:

(under subclass 272.11) Processes in which the component encapsulated is adapted to convert mechanical to electrical energy by electromagnetism or the component is an electric lamp or electric space discharge device.

(1) Note. Electric space discharge devices are defined for the purpose of classification as including any device which is intended to have an electric current flow between two spaced electrodes, at least part of the path followed by the discharge being constituted by a gas, vapor, or vacuum. Electric space discharge devices, therefore, include spark gaps, spark plugs, radio tubes, X-ray tubes, cathode-ray tubes, gas or vapor discharge lamps and lighting arresters of the electric space discharge type.
